Here is a directory of tube-based DACs ... although you asked for vinyl sound, not tube sound, this thread seems to have headed in the direction of tubes. Vinyl thru a solid state amp sounds different than CD thru a solid state amp. Either thru tubes sound different again -- 4 sound signatures for the 4 combinations.

To my ears, tubes (in amps, pre-amps, buffers, or DACs) add some very pleasing and euphonic harmonics that capture some of the real-world acoustic effects of certain types of live performances, especially those in small intimate rooms, and well-tuned concert halls (but not, e.g. in stadiums, and of little importance for studio albums). It does this to both analog and digital sources. Good soild state amps however seem more muscular (better transients), and often seem to me to have better separation and frequency response. Solid state
digital amps (class D, ICE, tripath ...) sound different still (a little towards crisp and away from mellow).
This is totally different IMO to the analog (vinyl) vs digital (CD and downloaded) source comparison. If you are not thrown for a loop by pops and clicks, vinyl does seem to have both better transients and smoother frequency response, although less detail and separation, than digital. Sometimes the detail in digital is too much, as when you can (in CDs mastered from older analog tapes) hear the tape hiss better than you can with the LP. With a modern CD that was digitally (and expertly) mastered, and recorded well in a studio, you can reach a level of perfection with regards to detail that I don't get from vinyl. I'll listen to an SACD of, say, a female vocalist with complex backing instrumentation through an tube HP amp ... I'll also listen to an LP through a solid state amp ... it all depends.
I have assembled the half-speed mastered LP, the SACD, and the re-mastered redbook CD of Carole King, Tapestry. I am attempting to listen to all of them with HE90's both thru a tube amp (HE90V) and thru a solid state amp (a digital one, in fact, PS Audio, using an energizer built by AudioCats employing Lundhal transformers). Of course the cartridge and phono stage make a difference, but there is only so much I can control!
I will report!
