Tube DAC Recommendations


I am in the market for DAC; my preference is a tube DAC. My primary music source will come from a computer or music server. The DAC will connect to Sim Audio 700i integrated amp. Budget is up to $7000 for the DAC.
I have been studying this forum over the last several months but cannot seem to find a consensus on the top 3-5 tube DACs.
Any input is appreciated.

Thanks

Yes, the Romulus absolutely fulfills my expectations. Full, rich, warm, pleasing with plenty of natural-sounding detail. The sound invites the listener to keep listening. Just guessing here, but I would think the only folks who may not be enamored with the Romulus would be those seeking the ultimate in bare-knuckle resolution, music be damned. It is funny that not much has been published yet about the Romulus or Pandora, although I suspect that some good reviews are coming before long. Let us know what happens.
Many thanks to all for your advice on this matter. It was a huge help to me in narrowing down the list.
I have decided to go with the Romulus.

Rtilden-
I appreciate all your comments concerning your experience with the Romulus. Keep me posted on what you do on the tube end.
Best.. Derek
Glad I was able to help. I will post back as requested, and I hope that you are able to favorably post back after your unit has broken in.
I am with Doggiehowser on this. I also have a PDX and have compared it to tons of stuff and nothing bests it so far. The only one that may do it is a Killer DAC which I have on order. I have heard it on a few occasions and know it is very good but haven't done a direct comparison to a PDX. That DAC was compared to a number of uber expensive DAC's by people whose ears I trust including an Audio Note and top of the line DCS Stack. The others were quickly eliminated leaving the Killer and DCS. It was a tie - the DCS was quicker with fantastic detail but the Killer simply sounded more natural and real.

When I get the Killer I will be doing a detailed comparison as well as lending it to guys I trust such as Doggiehowser so they can do the same.

Bob,The PDX looks like it cound be something special.Pasive resistor I/V straightforward output stage and wow, Duelund VSF capacitors with the level 2 mod(very interesting). What`s the output(volts) of this DAC and does it avoid the use of opamps? How stout is the power supply?
