@lowrider57 Did you ever deduce the issue? Did you try the iPurifier?
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.

@leemaze, Sorry for not updating this thread, I usually do. I upgraded to a used Audio Note DAC2.1 Signature, it's a NOS ladder dac. I decided to stop trying to put band-aids on a budget DAC. The AN has transformed my system, it sounds wonderful. It's very well built with a huge PS, tube rectification, tube gain-stage, and in-house dac chips. It's also possible that I prefer the sonics of a well executed NOS dac. Regarding the iPurifier, I tried it on both DAC's and w/o an external LPS it did not influence the SQ. I still have it and may be able to use it for it's optical capability into the new Dac. Thanks for asking, Jim |
iPurifier is a great tool for Dolby Digital and DTS jitter reduction. I use it in my home theater. For PCM, I recommend the Synchro-Mesh. Some jitter plots: https://www.audiocircle.com/index.php?topic=154408.0 For digital coax cables, I recommend my Reference BNC (RCA adapters) for $275.

@leemaze, Agon member jond recommended Audio Note after i posted a qwery about NOS dacs. Border Patrol and AN looked the most promising and as luck would have it, a dealer was selling a 2.1 Signature in XL condition. There was a 3.1 available, but I couldn't swing the extra cash. Regarding the iPurifier, every member here stated that it will not perform well with the stock wall-wart. It needs a linear PS with fast regulation and control of ripple current. There's a lot of info in the archives. I contacted Steve N. and the Synchro-mesh seems to be the best reclocker on the market today. I could have gone in that direction, but decided to first increase my budget and buy a better DAC. I have the PS Audio PWT, so my source is providing a well clocked data stream. You should check the archives about the iPurifier before giving up on it, it's only $150 plus the cost of a linear PS. Or go directly to the Synchro-mesh. |
