Any tube DACs with tight bass?

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.
