New or old DACS

[@richardt3371]

If Robert is talking about a Denon SACD player (rather than an amp, he doesn't say) then the Denon SACD player will not output the SACD layer via coaxial, so if the Burr Brown1792 is the built-in DAC then that's what he should use. I also don't agree with a generalisation that Delta-Sigma (DS) chips are better than R2R ladder DACS. And just finally, the Burr Brown PCM1792, 24bit / 192kHz converter is a brilliant DAC - no need to upgrade anything.

[@usaturnuranus]

Yes, my trusty old Yamaha receiver has 24/192 Burr Brown DAC as well, great sound.

[@D1N02]

It ain't that simple. Many high end Dacs are r2r ladder dacs. But you are going to pay for them. A simple Sigma Delta DAC may easily match them for detail extraction but many have a digital sound to them, les natural than what a good ladder dac can do.

[@Matt67012]

“Natural sound” 😅

[@stephens2r338]

I totally agree. As Paul has often said there's a lot more to a dac than just the chip. I use a 20 year old dCS Elgar which uses their own ring dac chips. IMO it still can still compete against the latest dacs in its used price class today and yes it can also play DSD. DSD sounds the best but is nothing new!

[@joshua43214]

I upgraded to a Holo May KTE DAC this year. I'll prolly never go back to sigma-delta. Also, the effective noise floor in even very high end gear is at 19 or 20 bit depth. Upsampling at the source to 20 bits puts all the noise of the digital side in the 20th bit, and leaves 19 bits for all the good stuff (assuming your gear is good enough).

[@kevingest5452]

I prefer the sound of the analog out of my Rotel RCD-950 from the mid 90s over running the coax to either my Schiit Modi or my Cambridge DAC magic. I attribute that to the Rotel having R2R rather than a delta sigma DAC. Of course the difference is subtle enough that it may be in my head, which is the more likely explanation.

[@digggerrjones7345]

BB 1792 *is* delta sigma! Higher bit and sampling rates *do not* always sound better!! Robert should just keep the Denon and enjoy the music!!!

[@archimagosmusings2708]

Agree. The PCM1792 is one of the Advanced Segment DACs and most of the internal processing is done through presumably multi-bit SDM. Also, modern DACs do not achieve anything close to 32-bit dynamic range. The best are around 21-bits.

@@rosswarren436(& andrew jackson) Agreed in every respect. Another technological backslide in my opinion are many current generation, remastered older recordings that have much improved instrument clarity, but sadly have badly overblown and over-compressed volume levels, which tends to pretty much flatline their dynamic range in many cases. I assume this is for catering to all the dedicated phone and/or portable music player fans who apparently only listen in noisy environments and have zero appreciation for the original recording's quietest passages being, well, quiet. I get that there are a lot of genres where everything is so over processed, autotuned, and workstation reedited to begin with so, like, what the hell does it actually matter, but I really wish they would maybe offer the user the option of purchasing a remastered version that has not been compressed and boosted to the extreme.

Technically the latest DACs may be superior in performance, but would my 68 (almost 69) year old ears really hear a difference? As a simple example, I recently changed the output of my Denon DCD-600NE CD player (great unit but nothing fancy) from the analog outputs to the TOSLINK outputs into my Denon AVR-X3500H home theater receiver to keep the signal all digital through the Audyssey process until the AVR's final D/A converter.

Great article on DAC's, but it won't work with Hi-Fi SACD players as the only output cd quality digitally, so Robert should not invest in an off board dac.

There is a transport recently available, perhaps from PS Audio, but it's silly money.

All true in general. Actually, I thought this would be an ideal time to mention that while most DACs are obsolete by the time you plug them in, the Direct Stream gets updates to stay current.

Also inexpensive by picking up these things at a thrift store and a good way to experiment with various chips.

You'd need a tube for each channel. Certain tubes/designs can color sound. So can cheap op amps. Neither are desirable. Lampizator created a pretty clean sounding triode amp using a Russian 6n2p triode. It replaced the output buffer typically made of several op amps and the result was no coloration, but just clean clear sound. It does not change the sound of the DAC, just lets it shine through. Some sound great, some not. All depends on what the DAC produces. But at least you hear it clearly. I did several and they all were a substantial improvement over stock. Not for everyone as we all have different tastes.

The chip hardly matters, and bit depth beyond 16 bit doesn't matter much since most music is only available in 16 bit resolution anyways. Even R2R vs delta sigma doesn't mean anything. What matters is the output stage of the dac. The reason so many people like the old R2R dacs is because most of those chips would force manufacturers to create a custom discrete output stage. Most modern chips force you to use the cheap built in opamp output stage and you have no say in the overall quality of the dac.

That is wrong. An the reason it is wrong has to do with the filtering. It you upsample your regular CDs, they don't magically create information that was not there in the first place, but the e.g. harshness the filters add otherwise like with older chips is shifted to where it does not matter.

"... get a pretty good approximation..."? PCM is based on each sample/ period in time/ ... having a specific measured and quantified value. Each sample stands alone and is basically independent of any others, You can take any instant in time and find out what it's value is by accessing that sample. Only a ladder DAC is capable of actually outputting this. You could feed a ladder DAC a single sample and it could reproduce that value until told otherwise. This is what PCM is based on. All of the sample to sample output levels then need to be integrated/ filtered/ smoothed to provide usable analog outputs. Sigma/ Delta is single bit (3 bit,...) with no reference to any actual specific value. S/D DACs have no idea what the data in a PCM file means. Feed one a single sample and see what it does. S/D takes PCM data as a suggestion. Not as an objective measured value. As does true DSD. They kind of float along keeping close to an ever changing stream. This provides some of the filtering/ smoothing needed to produce an analog output. But does so at the cost of actual technically specified values/ accuracy as a ladder DAC can. This begs the question of, if adherence to PCM is the goal, isn't a ladder DAC technically better/ required by default? Or is it the matter of what you like the sound of better instead?

This is one reason I'll never jump on the very small SACD train but instead will purchase DSD files and put them on USB flash drives to play them. Many receivers and CD players have a USB-A jack that allows just that. Yes, you are limited to whatever DAC is inside that device, but most of the CD players in the $500 and up range have "decent" DACs. It is a pity that stupid Sony still wields so much detrimental control, even now. Regarding I2S, it seems that some manufacturers are allowing the pin outs to be known and they can even be changed in software for compatibility. But doing that is likely above the heads of some audiophiles who are not "techie types".

@@gotham61 I'm simply stating how Paul does his productions. And even if he is wrong, it doesn't change the fact that he focused on the crux of the question. I'm not disagreeing with anyone. Just explaining why he may not have thought about what he said and why he didn't bother to address that specific issue. However, if he gets a question specifically asking about proper connections for SACD's and DAC, then I'm sure Paul world explain that in detail.

Most all the KZbin reviewers rave about the "wide soundstage, imaging, and natural tonality" of the communist Chinese made R2R DACs compared to most (but not all) sigma-delta chip-based ones. Is it snake oil? Is there any real electrical engineering reason that would be the case? Then I have read some posters say a $300 Geshelli Labs J2 DAC based on an AKM chip set sounds as good (or even has better bass extension and definition) than the $880 R2R Denafrips Ares II. As an audiophile with a modest ~$10K system, I want to get all I can from it, but I don't want to spend $880 to $2000 on a DAC if a $300 DAC + $80 linear power supply can offer 90% of that more expensive DAC. And obviously, it isn't just the architecture of the DAC itself but also what op-amps are chosen. Many say those op-amps have just as much to do with sound quality as whatever DAC chip or ladder is used along with the quality of the power supplies.

Not snake oil. China makes all the best stuff.

[@Montreal_Audio_Systems]

You need a 7000$ dac trust me. I tried everything and most of the Chinese high end ones you can't compare what a true high end not Chinese DAC can do! I was blown away

[@Pete.across.the.street]

@@Montreal_Audio_Systems go dacless with the Peachtree GaN 1, you won't regret it.

[@rosswarren436]

@@Montreal_Audio_Systems not really. My entire stereo is about $10K, so it would be foolish to spend $7K on a mere DAC. I can't see spending more than the cost of my preamp on one maximum. It's like there's no reason to put a 600 HP engine in a Honda Accord. But hey, it would be interesting to be able to do a blind comparison with a switcher between say a $400 DAC, a $1000 DAC, and a $7000 DAC just for the hell of it and see what results I'd find with my 64 year old ears

[@rosswarren436]

@@Pete.across.the.street they also make lots of crap and good luck getting it serviced after the warranty for a reasonable cost. And it isn't so much about it being Chinese as about my asking why does it seem that R2R DACs get the rave reviews compared to sigma-delta DACs, even at the same price points, Chinese or not. Say compare the $900 SMSL SU-10 (sigma-delta) with the similarly priced Denafrips Ares II (R2R). Which is "better"?

It seems Unlikely to me that a 15 year old Denon SACD player will have a DSD compatible digital output for connecting an external DAC. Just sayin’

PCM63P eats delta sigma buzzers, easy :)

[@ronniefranks4351]

Yep, that’s what my ancient Enlightened Audio Designs DSP-7000 Series III keeps telling me. I suspect I would be looking at multiple thousands of dollars to do better.

@@ronniefranks4351 solid dac, and with good selection of pcm63p chips inside. NOS is even better. Paul likes to oversample for some reason to astronomical levels, because i guess he thinks more is better - not quite. Sigma delta buzzers yes, it is a crap technology, made to be portable and cheap, takes so much to make it sound good as what r2r dacs do in a beat.

It would be great if one day you could explain how digital audio works ... 1 bit versus 16 bit and bit depth etc ... unless you've studied all this at college the average person won't have a clue what you're talking about. The sad thing is ... no one has ever set out to explain the basics of this either. All you get is a full blown very technical discussion on aspects of digital recording and transmission which offers very little help ...

[@JohnDoe-np3zk]

What a load of garbage. While DACs have sort of come a long way, the pcm1792 with hdcd has delta sigma plus 8x oversampling plus hdcd. Your lame non research is lame. The musicality was the entire point and my Rotel RCD1070 just sounds good.
