[quote user="Wojtek"]say how much the old man is involved in all this cult and noise around him? I've also read all the poetic stuff on the site and can't say that this mystical aproach is not appealing. I had the impression that Sakuma just entertai...

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...

[quote user="dazzdax"]Sakuma San is some sort of cult figure among the tube-o-philes. I wonder why he is implementing so many transformers in his amplifiers. Using transformers can be a good thing but in my experience too many transformers give a som...

Indeed,
a sad news. The Sakuma was not the person from whom I channel inspirations in
audio but the man was certainly driven by own interesting ideas. My favorite
about his idea to build an amplifier and to set it at the dining table
while it is ...

FYI
The news
On Sunday, December 13, Mr. Sakuma who was hospitalized due to poor physical condition passed away.
Wednesday, funeral
Date and time Tuesday (18th) Wednesday from 18 o'clock Wednesday (19th) Farewell ceremony From 12:30

…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...

Or perhaps he simply likes it to sound that way? You pursue one sonic ideal, Mr Sakuma obviously pursues a different one. The sound level - does Sakuma play louder or softer than you? My guess would be softer....

I wondered if Romy or anyone else has toyed with Sakuma's very interesting topological solutions. I have followed this for a number of years but my circuit building skills are so poor I figured I would likely blow something up.Adrian...

At the 7-level perceptual paradigm was operating not Sakuma by Cho-sun for Micro-Seiki. Sakuma was not operating in my view at any level but just listed highly band-passed, highly compressed gray sound. Nl, feels that “Systems like these are all abou...

I am categorical but very much not phanatical, it is interesting that you brought phanatisizm in context of Sakuma discussion. I am categorical in the facts about the sound that Sakuma demonstrated, and allegedly continue demonstrate via his “phanati...

[quote user="Romy the Cat"]So, Teflon, I do not think you got what I meant. SET has no 'topological limitation' because exists DSET. DSET is free from any, even theoretical limitation, of cause if you prepared to deal with price and power demand...
|
|
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 ...
|
|
Thanks, Jim, and thanks to everyone who replied in direct emails. Summarizing what was advised to me it looks like as now the input impedance of the amp is around 4.5K. That was roughly what I would like to have, though I would like to go even furthe...

[quote user="dazzdax"] Sakuma's idiosyncratic and esoteric way of thinking (he believes for example that tubes have a "soul") is not to everyone's liking. He is projecting his mind into a sort of tone control. At least for him this tone control bring...

The Sakuma schematic the was presented in there: http://www10.big.or.jp/~dh/msm/msm3.html…was not the one that I referred in my comment above. The bi-amp that seen/heard in Sakuma place was different. The one at the picture above is legitimate way to...

[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...

[quote user="Teflon"]I'm interested in bi-amping so you have my interest - if you say a SET has a 'topological limitation' what is the ridiculously simple change needed to make it good for LF operation ?I was previously thinking about using triodes i...

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 ...

|
Romy, can you say what you do not like in the Sakuma amp that is poor from a bi-amping stand point ?...
|
|
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...
