Pls recommend tube DAC

Monarchy M24. It's a tube DAC with a separate tube linestage in one chassis. I can't give you an indepth analysis, as I have limited experience with DACs and audio gear in general, but it has garnered very good reviews and I'm quite happy with it.

Go to the Monarchy site and read the Bound for Sound review if you're interested.

I use it as a preamp. The DAC has an optical and coaxial input, and the linestage has one (analog) RCA input. One for my Oppo, one for my Airport Express and one for my turntable.

OH.. the M24 is about $750.

I second the Paradisea. If you're patient, you'll find one come up on Agon for less than ebay.

I've heard nothing but good things about the Monarchy M24. As Elf73 points out, it can serve as a line stage too. Good article here:

A third thumbs up on the Paradisea+ USB.

Like is so often the case, there is no real interest in this post in recommendations of a tube dac, only of recommendations of a cheap tube dac. I would like truth in advertising.
