[@iam_mad]

The FM is the mor musical amp, has more near "tube" feeling, best choice for efficient speakers, but will less strongly drive very difficult speakers with less then 4 Ohms and loose bass drivers that need control. Dartzheel is like a power plant, can drive anything low efficient (what I don´t like) and can still make a very good sound, but not such a nice mid tone and bass like the FM. Either You get a really good speaker with the FM or You have the big 3 way or 4 way speaker (difficult to drive) and low impedance / efficiency, then go for Dartzheel.

[@demart28]

@@iam_mad which one would you choose to drive Monitor Audio RS6 Silver?

[@thomothomo1078]

@@iam_mad That is not how I hear it.The Dartzeel clone to me sounds warmer and more like a valve amp.The FM 300A copy sounds more like a good SS amp and can drive lower impedance loads better than the Dartzeel despite having less power.I own the dartzeel copy with the extra pair of output transistors.Both amps sound excellent.which is best probably comes down to speaker matching.The Dartzeel copy is superb with vintage Tannoy Monitor Gold15s.

[@iam_mad]

Its my pleasure to guide You 😊 Is there really a 10°C difference between the same transistors on R and L side? In my FM there is a difference of 2°C Did You find the zero point on the speaker outlets? In my FM I found the bias of 20 mV had the best sound with my fullrange speaker Bumbel Bee. The higher You drive the bias, the more heat You get, because You go towards ClassA The bias voltage is milli volt, means 1 of a thousand, 0,001 V. Make sure You have proper contact on the right side, where the terminal is missing!

[@alaingingras7224]

What I meant to say is both sides ,little red capped transistors get really hot@ 40 C.So I wonder If the bias has anything to do with this.I would try this myself but am afraid of the consequences...It was biased @18.3 mv.

Google "Musical Paradise" and compare it to Yours! I am right now working on the pairing with the "Musical Paradise" wich sounds absolutely fantastic! It is good to have a zero-negative feedback preamp, and keep the volume potis on the FM300A on 50%, then the tube preamp injects the good tomality into the FM300a (wich amplifies VERY precise) Nest video comes soon...

Hi, did you have any opportunity to try the FM711 mk2 clone?

[@iam_mad]

No, I am very happy with the sound of the FM300A, I don´t see the need for the 701- The point in the 300A is, the low feedback circuit design, that makes the sound so good. Adding circuits will mostly ruin the sound. But the nowadays speakers are all "slim bass colummn design" and have many small bass drivers with big excursion, they need these type of amplification with strong feedback circuits for control, which ruins the natural sound. I generally go for the speakers with real sound, 2 way monitor or fullrange driver. I will recieve the Dartzeel clone because of the demand, but I dont expect the big thing of it.

There is a fuse in the back plate of the Amp, I don´t know the Ampere rating right now. You can plaug any source via RCA jacks and level the volume with the two potentiometers at the front, but there is no remote control, since this power stage is from the 80ies and is all about sound without additions. It sounds great with any CD player, I used several DACs from Cambridge Audio to the famous Philips DAC960, but You could also use any preamp. I have combined it with the tube preamp MP-701 kk2, which gives You a tube like organic sound and more refined sound stage. Speakerwise I heard only positive response from most of known brands like Dali, Kef, Elac, etc. It also shines with fullrange speakers like the Sibelius or the Petit.

I bought one of these .Mine has a bad hum.I believe it is a ground loop hum.I researched this problem and after testing it in a way I will not go into it was obviously an earth problem.I bought an iFi GND Defender plug adaptor which simply plugs into the power input socket and then you plug the normal power chord into that.I was very skeptical about this thing working but it does exactly what it claims to do. No more hum! These are very high resolution amplifiers but neither do they sound analytical or clinical.Preamplifier matching is critical to get them sounding their best.With the right preamp they have good projection and depth but with some preamps will sound a bit flat.In my case it works best with my Suprtatek tube preamp [6SN7].I suspect it is one of those S.S.power amps that sounds best with high gain tube preamps [many do].

Hi thank you for the very interesting review I have been struck by one your statement in particular concerning the Canton sound I have always thought that a speaker keeps its own sound signature even with different amplifiers I was clearly wrong How do the Canton sound with the tube amp? Thanks again and kind regards Gino

[@iam_mad]

Thank You for Your comment! 😊 The sound of a speaker is always influenced by the amp, but this is much more depending on the efficiency of the speaker and the type of the amp. The tube Amp can show its great sound as more as higher is the efficiency of a speaker. In the case of the Canton, it is a low-efficiency speaker, so it will "swallow" the tube sound. (this is greatly simplified) The solid state amp can show its influence on the low-eff Canton much better, because it has simply the power to do so. (and the high attenuation) The high - eff - speakers show the sound of the Amp much clearer, and there tube amps can also shine. If You watch my build of the Petit (Speaker) then You see a High Efficiency speaker, that has even no cross over. 😉

@@iam_mad hi thank you so much for your kind and very valuable advice Actually I am watching the sound check video of the Petit and they seem to sound phenomenal indeed I will watch the other videos on their design and sincere compliments for your excellent work I had in mind a 2 ways speaker with a big woofer and a wide band driver used from let's say 200Hz up but it's a medium term project because i am moving to another home now Speaking of amps i am more a solid state guy for convenience Kindest regards gino

are you going to buy the FM 411 clone?

[@iam_mad]

Thanks for Your comment! I´m really happy with the FM300, so I think there is no need for the newer one, actually FM Acoustics did have a hard time to move on to a new model, because the 300 was so good, and so much requested by the customers. I don´t know how good the 411 sounds? 🤔 I saw the price of the original 68.000 CHF 😳 I will concentrate now on the pre amp (evt. with tubes) and the next speaker build! 😉

[@MasterofPlay7]

@@iam_mad well i think the clone doesn't cost that much, but yea what pre amp you are thinking of getting?

[@iam_mad]

@@MasterofPlay7 If You have the FM411 let us know about Your expierence! Since OldChen are quite good, I consider the OldChen C1 as the more "old fashioned" tube, and the Musical Paradise MP 701 MK2 is already on the way, this is a more modern design with a lot of customable options.

[@MasterofPlay7]

@@iam_mad for tube amp why didn't you get the wilsonton or cayin but oldchen?

[@iam_mad]

@@MasterofPlay7 because I go for the good stuff and buy everything with my private money 😉 (and OldChen has a reputation in the German high end circle) I would regard the Willsenton a more commercial product, and as You can watch on Skunkie´s channel, they need mods..

QUICK QUESTION: I have a pair of Klipsch RP-8000F II speakers and I need a (new) amplifier. Currently I am just using my old(er) Sony Home Theater Amplifier (STR-DH820) and these speakers are Very Bright with that amp. I don’t mind it for movies but for 2 channel listening my setup is just to bright/hot/has a digital sheen/whatever you want to label it. Speakers are amazing but this is just the wrong amp for them for music. Would this FM300A (in your opinion) work with these speakers and (hopefully) tone down the brightness when compared to my Sony AVR? I see Amazon has the FM300A listed as in stock (I am in Bend Oregon, USA) an am willing to order this if it’ll take care of my 2 channel listening issues. Thanks for any help you can provide - I Love Your Channel!!👏🤓

[@iam_mad]

I don´t see the FM300A on Amazon..? I only know it being sold on eBay, but You must be careful that it is the correct one, because there are cheaper versions, that don´t have the NOS transistors and the Hifi-Elna caps. I would not think to compare it to a Sony, since on my German channel some said it is much better then their Accuphase.😊 This is a bare power amplifier, and it doesnt have too much stuff in it to ruin the sound 😉

[@richardde-j8y]

i have this amp, sound is good, but it misses some power....too bad

[@matthewtaylor7355]

The red Wima caps can be upgraded.... Jantzen Silver Z Caps will increase detail etc...

[@WolfgangWimmer]

Hi Matthew, may I ask if you have done this, do you know which type of jantzen Silver Caps can be used exactly? Thx

[@matthewtaylor7355]

​@@WolfgangWimmersorry for the delay. I have not done it with Clone.. But with my 300b amp and large Tannoy. The detail increased alot

[@WolfgangWimmer]

@@matthewtaylor7355 This means you have a original FM Acoustics FM300b amp? In the meantime I changed to Jantzen Silver caps and also Mundorf Mylytic.

Hi I got one from alibaba. Great sound but then after like 10 minutes the power in my house gave up. Does this thing take a lot of power from the grid? But the sound was massive , hard to discribe that good . I used it with 30 year old mission loudsepakers ( 6 ohm ). Awsome sound. But the amplifier is dead now. Anyone had this experiance as well ? Maybe an emergensy fuse got damaged. I do not know what to do maybe send it back to china? i hope manufacturer has an answer for me. Otherwise I have to take the loss, that would be a pitty

[@maskapl]

Hi , I’ve same experience. After 4 days it died. On the pack there is special compartment with spare fuse. You can try to replaced. I did that and fuse keeps blowing. I tried about 5 fuses and cables, no luck. Did you resolve your issue? Thanks

[@wdsoft]

@@maskapl hi wel i ordered via Alibaba and has big issue sending it back. I had to pay for that myself. Wel didnot do that. Send my fn300 to repair shop and they found transformer broken. Hmm so contacted the manufacturer. Made a deal they would send me new transformer and an other fm300 on a 100 euro discount. She was going to let the engeneers test the fm300 extra. Wel this was the best u could do. So paid them . Will have to hope this thing is better and let repair man add the new transformer . If all ok i have two fn300. I have a pre- amplifier from same manufacturer. That is a fantastic device. Amazing sound. I run it with a 20 dollar Chinese digital amp and it sounds better then an onkio amplifier.

[@wdsoft]

@@maskapl i have ordered from brzhifi audio. This is the manufacturer

[@maskapl]

@@wdsoft but did you found what was wrong with that unit, why it was blowing fuses?

[@wdsoft]

Fuse broken then that big round thing was broken.

Why tf are the heat sinks covered???

[@iam_mad]

The heat development is very moderate, when playing silent it keeps completely cool.

[@MrRourk]

Noooo you voided the warranty! Buy a ST35 before they are all gone. The people in the tube world have rediscovered this great amp.

[@iam_mad]

Thank You for the recommendation! ☺ I like SE tube Amps a lot for the fullrange speaker, the push-pull would give a total different sound, I will dig that, when the time comes! 😉

You cannot evaluate sound via YT - you will always hear the sound of your PC connected system.
