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

My tried and true recommendation: Audio Note.

I have yet to hear a DAC I prefer.

It's strength is the orgnanic, natural quality of voice and instrument timbre, dynamics, and dimensionality. It has great frequency extension with clear highs and satisfying bass.

Only two downsides I can think of:
1- Essentially no USB support. If you need USB you will need a USB to SPDIF converter.
2- The DAC chip only supports up to 18/96.

Even with those limitations it is the most natural digital music experience I've ever heard.
I've heard the Aesthetix Pandora VC being feed from a PS Audio PWT into the AES input and a Auraliti PK 90 into the USB input. I agree with Rtilden's Romulus comments on break-in and sound quality with 16/44.1 recordings, but hirez from the PWT/PK90 takes it to another level,especialy when connected directly to your amps.
I have a level 2 PDX with Bybees all over the place as a special order. Like I say its the best DAC I have heard so far with one exception (aside from the Killer which may be better) - a Playback designs DAC I have on DSD - but only DSD - via PCM the PDX easily bests it - and of course its not valve.

Each DAC is hand built by the designer, Clay Geisner, to order, and the output resistor is adjusted to the input sensitivity of the amps being used. This is to make for easy direct connecting to the amps and using the volume control on the computer which myself and others found sounds the best. Its a bit better than the version with the volume control even though the particular volume control used is very transparent using LED's and not a pot.

No op amps or anything like that. The power supply is a special linear supply that plugs into your outlet and connects by a special supplied chord.

If you want to know more simply drop Lenehan Audio a line. The guy that runs it, Mike Lenehan, is really good to deal with. I am fortunate to live only about 30-40 minutes (so does my mate Doggiehowser) from the factory and know the guys there pretty well.

With the amount you have to spend I would look at the version I have with Bybees all over the place (on the power going in, from the DAC chip to the amp, and on the output). Its not on the site but just mention it to Mike and I am sure he will arrange for it.

Anyway good luck on your search.

Thanks bill,
No op amps,seperate power supply and Duelund caps,I`d like to hear this Lenehan PDX one day.
Regards,
Yea you and tons of others would love to hear the DAC. I am fortunate in being close to where they are made. Trouble is to keep costs down it is sold direct. If it was sold through a dealer network it would cost a lot more. That's the trouble with selling direct - you save - but you take a punt.

Thanks
