But how many valves does it use in the output stage to get that figure, and how much useable power do you actualy get for all that heat!

I‘m using the german made Eternal Arts OTL https://audioclassica.de/de/EternalArts-OTL-Mark-2.html into my QUAD ESL 57 QA https://www.quad-musik.de/index.php/...taten/esl57-qa and it‘s a match made in heaven. Lots of power and clarity!

4 per channel, and consumption is quoted as 0.7A, giving a quoted 15w/chBut how many valves does it use in the output stage to get that figure, and how much useable power do you actualy get for all that heat!

Graaf have been making OTL amps for a few years so you may be able to pick one up for a sensible price.
Here's a review

Is that .7A per channel, or total consumption, ie both channels ?

No worries, just found the info on them!

Not efficient by any means, but they do sound good. I had a 4w Mini Beast that did deeper and better bass than any SS amp I’ve tried.

So as you are aware:
current amp LAvardin IT
Speakers - Roksan Darius s11 (impedance drops to 4ohm) but actually easy to drive
I have a near field set-up - I need more load tolerance than I do outright power.
I have to say single ended is beguiling, but I've always found the bass a bit sloppy.
I like my IT but have had it now for 17 years - I did upgrade to V2 specs. I think it's time for a change - I am looking for a tad more warmth to come through

Indeed, also; i asume the over-all feedback must be quite high to acheive the output impedance figures quoted!
Either way; there are no perfect amplifiers, speakers, source equipment etc, so what ever works for a paticular system, and personal taste, is what this hobby is all about.
