Best 300B SET

Have to agree with Gsm18439(Gary). There are no shortage of worthy canidates in this realm. System matching and individual listening preference make it impossible to declare any of them the best. You can certainly say there are a variety of superb choices available.Those SETs listed above would qualify.

Asa,
The LM755 field coil speaker with your Air Tight 300b amplifier would seem to be a potentially superb combination.

Jet,
Our experiences are similar regarding 300b amps.My prior amplifier was a very good 100 watt(60 watt triode mode which I preferred) push pull class AB 6550/KT88.I wondered if the 8 watt SET 300b might let me down in some areas while excelling in others.It exceeded expectations(stunningly so) and the bigger push pull amp was retired long ago.

Given the talent and track record of Ken Shindo I'd expect that amplifier to be wonderful sounding. With the other excellent choices mentioned here I find it very difficult to deem anyone of them "the top choice". How did/would you reach such a determination? Edoit how did the Shindo WE 300b sound to you in relation to other 300b SETs?

Hi Pani,
In another thread you were considering other amplifiers for your Tannoys. If it came to a choice, would you,
1.keep the Wavac and find another speaker that's more compatible, or
2. Keep the Tannoy and replace the Wavac? Or has this issue been resolved?

Hi Pani,
I find the good 300b SET amps allow me to enjoy any genre of music. I'm primarily into jazz, big band and some classical music. However when I do play electronic Chicago blues or rock at home it is very satisfying and gets me very involved. I've concluded that it's really all about the amplifier and speaker match. My amp and speakers are made by the same builder so that's certainly an advantage(and short cut) for me. I share your thoughts on the fabulous midrange they provide. Personally the most nuanced, realistic tone and timbre I've ever experienced so far.
Charles,

Jet, absolutely +1, same results!

Discussions like this sometimes ignore the individuality of products. Which 845 or 300b amp? There's is a hierarchy and some will be better than others no doubt. What speaker is being driven? Another huge variable to factor in. It's difficult to group all together and genaralize.

There are many excellent choices and combinations available regarding SET amplifiers and appropriate efficient speakers. I love my Coincident system but I could replace it(although I won't) and start over and feel confident that other systems would be very pleasing as well. If you take your time and search there are great choices of brands is this very special genre. A brief list of speaker candidates, Trenner-Friedl Pharoah (and their RA Box model), Ocellia, Tonian Lab, Horning, Audiokinesis, Zu, Vaughn Audio, Audio Note UK, Coincident, Line Magnetic 755, there are a bunch more! High efficiency is definitely the way to go IMO.

The Trenner-Friedl was designed based on a 8 watt amplifier (300b SET?)
they had in their possession at the time. I'd email them for more insight and
their thoughts. You have many wonderful choices given that you're starting
from scratch. This should be quite exciting and fun for you. The Shindo WE
300b has been used successfully driving the Devore Silver back, so theT-
Friedl RA Box should be okay it would seem.
Charles,

I recall reading about this amplifier several years ago. Knowing the esteemed reputation of the designer and builder I'd imagine that it is a superb SET amplifier. It's likely difficult to find these days unfortunately. There's so much high quality equipment in this special genre of High End Audio. Low power amplifiers of this caliber provide beautiful realism.
