[quote user="drdna"] Would you then suggest that this approach demands the DSET approach to succeed? [/quote]
The DSET resolves all problems with SET amplification; it is not surprise that Sakuma went there. BTW, my familiarity with Sakuma’s DSET wa...

[quote user="Teflon"]If I understand you, your amplifier uses line level frequency selection at the input to each channel, and the output of each channel is optimized for the frequency range of interest -you worry not about the performance of a chann...

...you are too categorical and are on the boundary to be phanatical... Everybody and his ears. You can be sure I listened and owned many kinds of amps and my friend built some 40-50 non-Sakuma amps before he began with trans coupling and built anothe...

Nope, I do not have any proof to the rumor as I do not use the Japanese transformers. I heard them many times, was not liking the entire sound of the playbacks (do not blame only transformers for that) but since I never myself dealt with Japanese tra...

[quote user="Romy the Cat"]I did not have any low-power DHT but now what I do and when I drive 93dB sensitive speaker with it I have the very same ugly midbass that I experienced with countless setups of other people. I think it is a pattern. Also, r...

Thanks, John. We all adults and we all know how much difference between Realty and what we see on TV, particularly if we have done TV for living. As I told Sakuma might be is more interesting then the cult that I feel purely artificially is made abou...

I have near friend and he builds amps based on Sakuma ideas. They are nothing but compressed and band-limited. Quite opposite - wonderful tone, even balance, low-level detail and killing bass. His (and Sakuma?) theory is transformers provide optimal ...

I have run each of these for long periods and can validly comment.My power amp circuitry is a 6N1 based Mu Follower driving a 2A3 in turn driving a 3K Tamura amorphous core OPT.The 6N1 tube is a special military type that is not freely available.Ther...

Yeah, and I once thought Krell was the way to go, a boy's (or a man's) dream when I saw pictures of the KSA 100 poweramp for the first time. I must admit that in 1991 I heard a demo with Krell KAS poweramps, Wilson WATT/Puppy's + Pow Wow subwoofer an...

[quote user="dazzdax"]Recently I'm also using AC isolation transformers (from Tamura and Audio Consulting) with good results. [/quote]Chris,
I would like do not go on tangent but I am craving to write my News Release about the mentioned by you Audio...

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

…the theory that you not correctly presented BTW. Is it in an amp with a half-dozen series transformers Sakuma has the “killing bass”? The Sakuma amps are bandwidth limited by default, it is what BTW Sakuma went to DSET to fight the bandw...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

Hi Romy,I see why you don't like the design. And in particular, the choice of where he chose to limit the frequency responses for the two channels. I see the benefit of the DSET approach in this context as you explained it. If I understand you, your ...
