Looking for Better Jitter Reduction in a DAC

I'm looking to improve the jitter control in my digital setup, which hopefully will create a more analogue presentation. I own a PS Audio PW Memory Transport, which sports a FPGA, and a Nuwave DSD DAC with a scaled-down version of the gate array.

   I have owned a Chord which uses this technology and it was like listening to analogue recordings. I sold it only because it's soundstage was very forward, like sitting in the front row of a concert hall. My current PS Audio setup has wide and deep imaging, as does my Atma-Sphere preamp.
   I have auditioned the Schiit Grundir and it was a bit too fast in the attack and transients, but had the dynamics and deep imaging that I like. So, I guess what I'm looking for is a unit with a laid-back, realistic musical presentation.

The Mytek Digital Stereo192 DSD and Blue Circle DAC are in my price range, but there is no way to audition them.
  So any recommendation and advice is appreciated. DSD preferred, budget is about $1200 used.

@dlcockrum/Dave,

I see you own Tommy's DAC. I'm curious why you decided on the DAC DAC and what other DACs you've had in your system prior to deciding on it. I own the HS version and really like it but haven't had a chance to voice many other DACs.

Thanks,

Gary

P.S. How much of an incremental improvement did you experience with the Uptone gear?

All (rpt all) DACs should be isolated from very low frequency vibration and some internal damping might also be advisable. All circuit boards should be isolated from the chassis, you know, as opposed to being coupled to the chassis.

Hi gareneau,

Not sure what "Tommy’s DAC DAC" is. I currently have the Exogal Comet Plus. I will report on the ISO Regen/UltraCap LPS-1 combo this weekend.

Geoff, the DAC, ISO Regent and UltraCap LPS-1 power supply sit on a Symposium Svelte platform. Not planning to decouple the internals from the chassis but I get your point.

Dave,

My mistake. My email should have been directed to Chris (rodge827).

Chris, I'm interested in your thoughts on Tommy's (owner of Digital Amplification Company) DAC - called the DAC DAC, of course. And the Uptone gear that you have with it -

@dlcockrum , the UltraCap LPS-1 looks like a great device. But what is the advantage of the LPS-1 over a traditional LPS with a toroidal transformer, e.g.; Teddy Pardo?
  According to the Uptone website, it has superior isolation to prevent AC leakage via the UltraCap™.  The Teddy also claims to have isolation thru its proprietary low pass filter and series of capacitors.
   Also, what is the LPS-1 using as a transformer?

If I can get a better understanding of this new LPS, I'd like to make a purchase.
