What's the greatest bargain in SET these days?

I would buy that explanation. In my case I have a set on the radar screen somday as a good solution with a wider variety of speaker designs for lower level more casual listening. Good for the ears no doubt. That would be another advantage for music lovers looking to preserve their hearing. Also I believe lower listening levels tend to fare better more often for minimizing listening fatigue which tends to increase listening enjoyment. At least for forms of music conducive for low level listening.

Rebbi, the 300B with David's "5.6" model speakers (with his proprietary 15" AN drivers) were among my favorite combinations at RMAF this year...at all of $3.5K total for the pair (including the speaker build). The incongruity between sound and price tag on that system was second only to the little Linkwitz omni built from Home Depot PVC pipe that costs $450 to build (now THAT was an eye opener...).

The only "trouble" with the AN 5.6s (for me) was that they are far too large (44T X 18W X 14.74) for any space I'm likely to occupy in the near future. But they were pretty darn sweet...

Al,
That observation correlates with my listening experience.With the sensitivity of my speakers (94 db and 14 ohm load)sitting 10 feet from the speakers. My average SPL listening is 75-80 db C weighted with a range with most jazz CD recordings from soft (low 50s db) to (88-90 db peaks). Most of the time amp is using "fractions" of 1 watt up to 1-2 watts of power. So distortion is very low. This explains the high resolution,transparency and very subtle nuance retrival. These levels are very easy on the ears and yet enjoyable and involving. Loudest I've gone was 102-104 db with cranked up jazz drumming and rock(the Doors and also N. Young).It was good at those high levels(done rarely).

Mdemaio,
What you report is very good news for many people. High quality sound for very reasonable cost. Seems that's quite a 300b SET for 1550.00

Hi Rebbi,
The more I reflect on your situation and choices, the more attractive the Commomsense Audio SET amp becomes.Mdemaio said it was very close to the Audion SET in sound quality. That's high praise given the Audion's stature and reputation. To get this for 1550.00 is remarkable IMO. This price gives you room for possible upgraded parts, I'd ask David if for a bit more money could the caps,wire,resistors be improved.These parts are crucial to getting top level sound. I wouldn't cut corners here to save a few dollars. He might say the chosen parts are already top quality(for all I know).

For instance using some Jupiter copper foil coupling capacitors would be excellent(they aren't crazy expensive either). Have him use the best wire you can afford, If you get this right the first time you'll have a SET that can keep you happy for many years. Of course I have no idea if he's open to this approach or not. SET circuits are so bare bones pure and simple that you'll hear what each part has to offer.
