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.

I'm using a PSA PWT Coaxial out to an iFi SPDIF iPurifier ($150.00 Music Direct 60 day return policy) with excellent results! It sound good out of the box. After 200 hours of run in it has really hit its stride. Better instrument separation, imaging, sound stage, nuances, and defined bass response to name a few things. I have owned the Syncro Mesh and though it is a good performer, but the cost is way too high especially since you need to purchase the upgraded Dynamo PS for best results. I just purchased an Uptone Audio Ultra Cap LPS-1 that will be delivered sometime next week. I'm not sure if it is needed but thought to give it a try. Super quiet power supplies are a must to get the best out of digital audio.
Current Digital Front End: PSA PWT > Virtual Mode Coaxial Digital Cable > iFi SPDIF iPurifier> Digital Amplifier Company DAC TS version

I have had many different digital front end set ups over the years and this set up rivals the best of them.

NAD Master series had a DAC that I was looking at about a year back that had an IS2 input and was going for about a grand used and got a favorable review from J.A. In Stereophile.

Hi david_ten,

I violated the audiophile cardinal rule and changed speaker cables right after adding the ISO Regen. I figure late this week will be enough time for the new SCs to settle and for me to adjust, so I will do some with and without ISO Regen trials and report back.

Dave, I’ve had a number of change ups of late also, which does impact evaluation. I’m repeating something you most certainly know...enjoy the gear for a few weeks and then remove the Uptone products. : )

I’ve had my replacement ISOREGEN for a couple of weeks now. It is powered by the UltraCap LPS-1 also. I’m in the same situation as you are.
