If you truly want a true reference quality SET 300 B amplifier
Radu Tarta Shiny eyes products are way under the radar and No commercial
brands are even remotely close to his expertise . In Europe Thomas Meyer is his equal . What most miss is the sheer quality and engineering expertise on all levels
inside and out . Look at U.S Audio Mart he has a absolutely fantastic 2 box 300B amp that I have heard is stunningly good with premium tubes and choices of input tubes you can use for tastes of all music types it’s $10k+ , But if this were made by a big commercial company this would be with ease$25k,it’s that good, check it out !
@donsachs I am seriously thinking of coming to Seattle for the audio show in June. Are you going to be there every day? I've never been to one of these shows before. Meeting you in person (finally) and seeing your 300b mono blocks is a main motivator.
Not to tread on any designers toes in any way, more a testimonial to the impression a well thought out 300b design can have.
I have heard 300b Valve Amp's over the years, mainly SET with low Watt Output.
I have liked the vocal and simple acoustic music when replayed through them, but in general have not got too attached to these types of design.
Recently I have been auditioned a Tim De Paravicini design PP 300b that was in production 30ish years ago.
A friend has purchased it, who has a system I know very well and have been used to hearting Neurochrome SS Amplification and VAC Valve Amplification. The Amp' was given a pre-heat prior to my arrival, the impact the the TDP design 300b Amp has made on the presentation was quite instant. I was aware something quite special was being used and become very contented with hearing a 300b Amp' in use that were really worth making a reference to, hence I am producing this post.
The Amp's owner has informed me the Neurochrome and VAC Amp were now most likely to be sold, as they do not foresee the need for them any longer.
There is in my opinion a a new satisfaction in place. This is so far achieved without a Tube Roll, or a swap out of some very old Cap's.
A PP 300b Amp can really work for those who have struggled with the Tubes used as a SET dsign.
