Yes, according to the manufacturer's homepage it is sold at € 3,900 »only«, which is about $ 4,100.

But alas, I read 4 pc.12AU7 tubes? They aren't of the very best reputation in AF amplification, are they?

Cheers!

Yes, I can edit the title, but I'd prefer that underwurlde request that I do so first.

Today's exchange rate would make that a little over $4700 USD...

The 12AU7A/ECC82 would not be my first choice, but long ago I did offer an inexpensive line stage that used them - not too shabby for the price point. Linearity is the concern, but can vary significantly from brand to brand.

I think the one in the picture is a later generation Ongaku which is more subtle than the earliest version that had the preamp tubes sticking out at the top front enclosure that's less appealing to me.

I don't know the sound so I can't comment if it's worth the price. But sound quality of such item to the potential buyers, believe it or not, is not always paramount...

If I read correctly both Kondo and Audio note UK is using 12AU7 variants in their best designs .I think it's all in application .

12AU7 is a pretty nasty valve; fine for old TV sets and guitar amplifiers. Morgan Jones demonstrated that its distortion performance - notably third harmonic - is very poor. Years ago I tested a few myself and the results were similar. I would never use 12AU7 in an amplifier, after all there are many better and indeed, cheaper options.

I think $4700 may be fair price today. But if to take this ready construction, copy and start mass production in China, of course it may cost under $1000.
DIYers who copy designs don't know how much R/D can cost. It is much more than cost of parts in the final product.

A tube amplifier does not need R&D. Everything is invented in the first half of the last century...
