this is an absolutely gold vlog teaching for audiophile. i plan to use trinnov altitude for my surround processing. if i didn't mistakenly heard, it has active crossover for each channels, correct me if i'm wrong. so hypothetically, if i were to build a symmetrical 25 surround channels, (floor, bed & height channels including main LCRs and top center voice-of-god height speaker) that would sum up to 50 discrete channels yes? 25 high frequency and 25 low-mid frequency channels. correct me if i'm wrong here. 2. also in regards to trinnov, their bass management and wave forming, does the 1.25 of A listening position still applies? i highly appreciate your vlog Mr. Guntars, top-notch educational stuffs.

Hi, thank you for the inspiring comment. With the Trinnov altitude processor, you are stepping into the next-generation home cinema. And what is most important is that the processor is separated from the amplifier. It is important because THD processing and amplifiers are developing at different speeds, similar to photography where a good lens is living 10 times the camera body life’s. Modern amplifier boards in home cinema exceed human hearing limits, but THD processing is still in development. In-home cinema speaker placement is less critical because you have a number of them filling the room and reducing room impact. Subwoofer placement issues are compensated by the digital processor changing phase and volume of low-level signal in the digital processor. The measurement microphone takes the role of a precise listener. Wit stereo everything is so critical due to non-optimal standards. It would be far simpler in the case of 3 speaker systems- left, right, and center. Historically stereo is developed as 2 2-channel system where a 3-dimensional effect is generated by our brain capability which is adding critical placement limits.

I was wondering about the pillows, i understand that you need dampening, but making those small pillows, will they not take up cabinet space, as far as i know, you would want a filler that lets air pass through it, are you making a compromise, or are there something i miss? Lovely work anyways.
@guntarssmits2104 28 күн бұрын
You are losing physical space but not cabinet and loudspeaker interaction volume. Physically dampening is rising box volume and lowering woofer and box calculated resonance frequency. Dampening works so that sound initiates fibers and converts them into heat. The dampening volume extension ratio is calculated when using good speaker design software.

Yes, it works as energy storage for instant power delivery and improves the system's dynamics. The best place for this capacitor would be on the board close to the chipset. In this particular case, it was placed at the output of the power supply.

oh boy! so many false statements here... amplifiers have surpassed the human ear.. wow... bla bla bla and .. the icepower is becoming the best amplifier. again according to Guntars. Are you affiliated with Icepower sales anyhow? For example he's comparing Purifi's and Icepower's THD+noise vs power graphs - and the icepower shows like10 times higher distortion and in high frequencies the distortion gets even worse but Guntars with a straight face tells you that icepower is better digressing on cars horse power keeping mum on the obvious drawbacks. Any icepower boards measure worse that purifi and hypex NC. Eg - icepoer's thd+noise reach 0.01% (purifi below 0.0002% on listening levels) Those best specs like noise etc are only measure best at over 70% of power. At listening levels the distortion is worse. How often do you listen to music at home at 700 watts?? may be at 1200 watts? Icepower is worse on multitone signal measurements as well. Sonic-wise, i've owned a number of icepower's, hypex's, purifi's boards and hi-end assemblies, icepower is only interesting in the mid-bass, overall loses to purifi and hypex (NC). icepower is on par with UcD. And if you do a clean proper power on the buffer stage replacing the obsolete opams then UcD sounds better. You can't do much about those stupid icepower's chips. They use only basic power cleaning on the buffers. Proprietary chips approach is con, not pro. Generally, Icepower are decent energy efficient amps, especially for stage use and multi way diy speakers tending to lose microdetails compared to real hi-end amps being tube, solid or class-D and it's not home audio high-end domain yet as proven by listening and measurements. Seems, Gutars's a good engineer, I'd suggest he gets to build a proper speaker system around topline Scan-speak, Seas Excel or even Purifi or Accuton drivers then we debate on "Current designs exceed human hearing resolution at least 10 times". Still interesting video, liked.

There is no magic in amplifier design. Non of Hypex, Purify, or Ice power has its developed semiconductors. Today, the amplifier game is over. There are lines of amplifier boards exceeding human hearing limits. In most cases, the statement that this amplifier has better mids, in reality, means a power supply problem and suppressed low frequencies. In simple amplifier has coloration. According to TI research 100W amplifier power supply should be capable of delivering 800W short-term power. Most 400W amplifier designs power supply is a limit to perfection, not THD. Genelec - a World higher resolution studio monitor manufacturer states that amplifier THD for their speakers should be 0.01%. I know that consumer marketing is crazy strong and some messages are seeded in the audiophile community, but it is nothing about precise audio performance. 20 other specs are having more impact on sound reproduction than THD. My focus on Icepower is due to their professional board’s availability to the consumer market and reasonable pricing. Today you can make high-end amplifier within a 1000 EUR budget and it is very close to perfection. Want to get better sound reproduction you should go for multi-amplifier architecture with active crossover where the number of loudspeakers in a box is driven by dedicated amplifiers. The worst thing you have in your audio system is passive crossover. Once you get rid of that you are at a different reproduction tolerance.

@@guntarssmits2104 SPL dB/w/m min/max guitar: 40/55, rock band: 80/110, orchestra: 35/110, jet plane: 130. To reproduce an orchestra you need spl of 110 db W/m. Regular speaker drivers' sensitivity is 86-89 dB W/m, better ones reach 98-103 literally meaning you need to connect 1 watt to a driver and you get spl of 86 to 103 dB at 1kH depending on the driver. Hence to reach orchestra spl you'll need only several watts, in case of ineffective drivers - tens. Hi-end single ended tube amps often have like 8w output. So, the statement that you need 400W or even 1200W to reach realistic SPL level even considering low frequencies and picks is limply incorrect. Yes, i'm aware on the studies that power units should be able to deliver higher level of power instantaneously and this is not for SPL reaching but for the amplitude to rise fast enough. And it's true there. Like many I tend to disagree with you that the amplifiers game is over otherwise all amplifiers would have sounded the same had you connected them to your speakers. But this is not happening. The bottleneck will always be transducing electric signals to sound waves (speakers). The best of these have THD around 0.5% in the mids but not three - four zeros after the dot. Multi-amplifier is a good approach; but you gotta make sure that your drivers are properly time delayed from the lowest woofer in the system and equalized. Interesting fact that Troels found that multi-amplification speakers sounded worse then passively x-overed. And from my experience I tend to agree. I saw you had built some of Troel's speakers. On the other hand a proper active crossover is much easier to build than a passive one.

@@RomanTecDev To limit the long discussion, I recommend watching the Harbeth lab ( ex BBC acoustics research lab) experiment where a lifetime top speaker designer demonstrates real speaker peak power consumption. kzbin.info/www/bejne/j2S6oYWPYqqnjpo Before calculation, we should drill down a bit into the physics topic. Speaker sensitivities are given to 1kHz where huma has high sensitivity hearing. For 100Hz our hearing is 100 times lower and for 40Hz 1000 times lower. Sound is all about speaker acceleration (not movement); we are dealing with high mass and high-power motor physical models for low frequencies. There are similarities with a car accelerating from a red light where an odometer shows fuel consumption of 50L/ 100km. When we finish acceleration, it is just 6l/100km. Amplifier peak power capability is the same as 50L/100km. In the moment you are not able to provide it your drum kick is suppressed. Music mastering in the studio is done on high power-driven speakers capable of significant SPL at low frequencies and you at home should be able to replicate it.

300AS1 monoblocks would still be a good addition to a line between 200AS2 and 1200AS1 because the stereo separation is the absolute best it can be. A 1200W amplifier for stereo listening is probably a lot of fun but it's more than a lot of people need, and it's a physically large chassis with a high price tag. The benefits of modern Class-D amplifiers are incredible; there is now no need for a large case, heavy transformer, and heavy heatsinks. It seems like the product line should be structured: 200AS2, 300AS1, 1200AS2, 1200AS1. For my own use I plan to build a 200AS2 for my desktop and a pair of 300AS1 for my second system. My main system is using Hypex NCoreX NCx500 monoblocks with 1200W power supply and that is more power than I require, but this was the point - no further upgrade path.

The price of the 300 AS1 project is very close to 1200 AS2. But 1200 Is by far the better solution. You can use it as an end-game amplifier for desktop to large floor standings. Self noise is so low that it seems the system is silent from 10cm.

I completed my 200AS2 stereo project and dual 300AS1 monoblock project. I feel like the sound from both amps is state of the art in the application where I am using each one, when feeding each one with a modern, nearly-perfect DAC with volume control, such as the SMSL RAW-MDA1. A benefit of the 300AS1 monoblock is that it has more power supply capacity dedicated to each channel; the 200AS2 shares a 300W SMPS between two amp channels that can deliver 200W individually or 150W when both operating together, while the 300AS1 has a dedicated 300W SMPS for each amplifier channel, there are just two boards required when providing 2 channels of amplification to a 2-channel audio system, two cases, etc.; naturally that costs more.

The importance of damping factor is interesting. The damping factor is the relationship between the amplifiers output impedance , and the loudspeaker impedance. The biggest advantage of a high damping factor (low amplifier impedance compared to the loudspeaker impedance) is to "brake" the back-EMF generated from the loudspeaker. But here is the fun bit: When the loudspeaker generates high back-EMF is when the cone excursion is high, but when the excursion is high, the impedance of the speaker is always high in most cases, due to resonances and so on. This will then automaticly increase the damping factor..

@guntarssmits2104 4 ай бұрын
There are four grades of measurement. But you should start with optimum speaker placement anyway to get a good sound stage. The first is my described method with headphones where you insulate yourself from the room and then compare both in-room and headphones to try to get as close as possible. It is a simple and precise method that includes room influence. The second is to apply the noise with one of the measurement software and try to get a flat response. It also includes room impact. May be good to properly place speakers. The third - get linear anachronic chamber response using digital DSP and step response where I do not see any value unless you are not in the treated room. The room will spoil everything And the fourth - have a treated room and by using DSP crossover fix everything that you can. It is a complex task and you need knowledge close to the studio mastering person. Modern DSP crossovers with parametric filters in the hands of beginners in most cases land with failure. Your music listening experience will not improve but you will have a perfectly neutral sonic balance to be able to mix recordings. The funny thing is that with the first method you are at 95% of the audio quality.

On a scale from 1-10, it will be “0”.DSP can change some coloration issues, extend bass performance, correct baffle compensation, correct some loudspeaker components design amplitude frequency limitations, and do speaker time alignment but cannot change room reflection soundstage smash. Your active system's largest benefit is loudspeaker driving tolerance and control which you can describe as detalization. To further improve your sound stage you should use speakers with waveguides forming more focused direct radiation and narrow vertical plane radiation. At some point, you are at your current system limits and the next step is room treatment or rearranging your listening sofa configuration to be closer to speakers. In my video, there are THX placement recommendations drawings and those are industry standards for the best result. No shortcuts, sorry😊

@@partyk138 In most cases for home usage you do not need DSP. DSP is great for pro musicians when you change performance places, have many speaker boxes, and get nasty reflections from architectural constructions. With more than 40 DSP adjustment parameters you can get more or less acceptable sound for live performance and suppress some positive microphone feedback. To simplify this process test signals are built into the crossover DSP, and typically good DSP crossover has measurement microphone input. For home usage, you do not get much from DSP You can improve some tiny bit of coloration, but your overall impression is minor or not improved. There are only a few potential steps with a big impact - amplifier power, amplifier bridging, and direct loudspeaker connection to multichannel amplifiers with crossover prior amplifiers. The rest of the processing has a minor impact on your listening experience. In the case of home recording, you should start with room treatment and then use DSP and acoustic measurements to get a neutral sonic balance for proper mixing.

It would be best if you looked at 1200AS2 as a power stage of the amplifier and it is meant to work from a preamp with a volume regulator. For 4 ohms load to get out full power, you need a balance 2V RMS input level, for 8 Ohms you need 3.8V RMS (5V peak). For an unbalanced connection, the input level should be double. I think this is the main reason your output level is not sufficient. 1200 will work great with professional audio interfaces, modern DACs, and streamers with balanced outputs.

@@Thor777AHT When we are talking about amplifier quality it by far is not the worst component in your music reproduction path -Preamp, amplifier, passive crossover, speaker, and Human hearing psychoacoustics resolution. My personal experience shows that any modern well-built amplifier exceeds speaker reproduction tolerance and human hearing resolution which is relatively low compared to audio amplifier tolerance. When I hear amplifier improvements? first by adding power from 100W to 400W, precisely bridging (Quadro balanced) when improving the sleave rate without changing bandwidth. One of the amplifiers goes halfway up, and the other goes halfway down making an instant push-pull system that doubles speaker driving performance, and the last, most efficient improvement, is connecting loudspeakers directly to the amplifier output and using active crossover before the amplifiers. In that case, you eliminate losses in Passive crossover. You need 4-6 channel different power amplifiers to make such a system. I just published a series of videos about such a system on my channel. To argue with your father and other amplifier enthusiasts you should look at the complete system. Even if the amplifier is super fast, you are driving the speaker membrane with a limited force motor and significant membrane mass. All supper-fast microforces are lost in a lousy speaker execution system and inertia. I would say that no feedback system can’t impact sound reproduction detalization. Especially when you have a passive crossover with large reactive energy-storing elements (Inductors and capacitors) in between. This is theory. In practice, the blind listening test may be able answer to this century's question. 😊

The Chinese sell these devices as Hi-Fi. But can you tell me that the TRA 3255 can work as a HI-FI amplifier? Thanks!

We need to define the Hi-Fi amplifier criteria. For near field monitors (1m listening) for Hi-Fi you need 100-150W power. For Floor standing at a distance 2-3mm you need 400W clean power. The simple answer is that TPA3255 can be treated as a Hi-FI amplifier for near-field monitors under one condition -good power supply quality. Most Chinese amplifiers come with PC industrial power supplies which can’t provide short-term instant power. 100W amplifier power supply should be able for the short term provide about 8 times RMS power - about 800W for about a second. The power supply should have a different architecture. Otherwise, TPA3255 is a very good amplifier especially used in stereo bridged mode (chip has 4 channels) it measures well and it sounds good, and proper builds are far better than 120W AB class amplifiers. There are several Audio science reviews rating it high. But as I said, power supply is an issue in most budget offerings. You can measure it well for constant power but dynamic characteristics are more important. Sound quality is all about the amplifier's capability to accelerate the speaker membrane at any rated power and the engine of the amplifier is power supply instant power.

outdated, the new hypex is better

By drilling down into the topic you may find that human earing has relatively low resolution. THD max resolution is 0.25%, amplifiers can easily make 0.005%, and Amplitude resolution is 0.25dB at midrange around 3kHz and 3dB at 50Hz and 16kHz. Damping factor max value 50 (amplifiers can do 700 and more). The basic parameter specifications improvements do not make sense. But such things as quadro balanced (bridged), power supply instant power capability, thermal design, etc become critical parameters when we are talking about amplifier quality. And the right direction to audibly improve your system is using active crossover and active speaker systems. Most of Chipamp's active systems sound better than most advanced Icepower Hypex or Purifi most expensive amplifiers with passive crossover speaker systems. By architecture, Quado balanced design, power supply instant power capability, audio quality, output power, and telemetry built-in Icepower 1200AS2 is the best amplifier board today. It is available for the DIY community from EU-proven retailer Soundimport.

Hi I know this is an old video I hope you are pronouncing chassis better, if you are still struggling try pronouncing it ( sha sea ) sha pronounced with the A pronounced the same as you would say cat, mat hat. Hope that makes sense.

Yes, any foreign language is art. Thank you for pointing it out. I am confident that I will use developing AI language technologies for videos shortly. Today not up to level yet but progressing fast.

A quick look at ICEpower's specs shows moderately low distortion and a rising output impedance with frequency. This demonstrates that they have not been able to do what Hypex and Purifi have succeeded in doing, namely put the output inductor filter inside the feedback loop and maintain stability. This means less feedback and higher distortion caused by the output inductor being outside the feedback loop. ICEpower is thus stuck in older technology with poorer specs. Buy it if you like it, but if you want super low distortion and high damping factor at all frequencies, look elsewhere.
