i did, murray. they vary in sound - some i liked, some i didn't. i will focus on them more very soon when my new speakers arrive.

everything is built to order and there is a flexibility in meeting your demands. that is also one of the reasons why they don't sound consistent - i mean 2 similar amps do, but there are so many variables re what caps, resistors or valves fit into your budget.

the prices are always discussed upon the requested specs but they are not expensive. they do cost more than chinese but certainly less than europeans.

however, my favourite manufacturer from this part of the world is:

there is an english section of his website.

he is cheaper and (for my taste) more focused on the real issues of the SETs - i think he recently build a custom order SET with ITs for someone from norway, based on a russian military version of 2A3 (6B4G or something like that). he is fanatically dedicated to the SETs, he bulds his own transformers and at the end charges really very moderately for what you get. most of the amps shown there are between 600 and 900E, the preamps are under 400E. we tried to estimate what is his margin - it's not more than 150-200E per amp.
