Any tube DACs with tight bass?


From a number of reviews of tubed DAC's, a common theme seems to be that the bass can be soft/loose/ripe/etc. I realize that one is unlikely to find Krell/Levinson/Wadia bass from such designs, but which tube DAC's give well-defined bass as well as rich, full mids? (I'm not worried about "rolled-off" highs... this is usually welcome on most CD's).

Best tube dacs I heard are.
Jadis JS-1. This is a one bit tube dac.
This Jadis is from the mid to late 90s.
It sounded so airy and smooth. The power supply was a tubed power supply.

Jadis JS-2 MkII This is the 24 bit dac version.

Metronome C1A DAC and C20 Signature Dac.
These tube dacs sound phenominal.

Musical Fidelity TRI-VISTA 21 DAC
One of the best.

Audio Logic a longtime favorite.
Ditto on the Audio Logic, i just got a minty model 34 to replace my long stand-by modded Alpha, this thing really rocks out in a MAJOR way, plus it has four tubes for me to roll if i want to. It's a definate keeper.
the new updated audiologic model 24 with the transformers
might be the best tube DAC any place . you will never go wrong with any audiologic product. as for bass it is as good as any DAC that i have ever heard.
