Upgrade bug has hit, interested in Pass Labs Amps

Messelt, I agree that your Kimber USB cable could be part of the issue. . . my experiences with listening Kimber wiring is that they tend to be a bit on the tippy side. Not sure that going to a glass connection would improve things though. . . a glass fiber connection means that the electrical signal is converted to light pulses at one end, then back to electrical signals at the other end of the wire run. . . that introduces additional potential for timing inaccuracies or jitter. . . which we perceive as edginess in the sound. What power cords are you using on your Ref 1000? I am having excewllent results with Cardas Golden Ref on the Mk.2s. G.

I am using Analysis Plus Power Oval 10 for the Ref1000s and a Aural Symphonics Cappuccino for the DAC3. I am in the process of running a dedicated circuit for the ref1000s using a hospital grade duplex (all thats in the budget for now.) Maybe that will help with my issues for a while. That will not happen for a few weeks, I have to install a sub panel as I have no room for expansion in my current panel.

Guido, you lost me there. Cardas Golden Reference????? I tried those and they mushed the sound horribly. All cables with heavy dielectrics do the same. It was the Anti-Cable that taught me to try naked ribbons.

A lot of the testimonials at Spetz's site are from former Analysis users.

Hi Messelt, I am grasping at straws of course, but I suspect that the Oval 2 may be a better choice for the BC amps than the Oval 10. . . I know that Oval 2s are often recommended with other class D amps like the JRDG 201s and 501s. . . I even heard Oval 2 on the big JRDG 312 and it works quite well. If i interpreted the descriptive page on PCs on the Analysis Plus web site correctly, the Oval 2 PC has a braided shielding. I just recently read somewhere on Audiogon that shielded PCs may be appropriate for some switching amps. As far as I know, the Cardas Golden Refs are shielded, and they sure work well on the BC Ref 1000 Mk.2s in my system.
Yet, I also suspect that the Kimber USB cable may be part of your problem set. . . . I heard very good things instead of the Ridge Street Audio USB wire. . . mind you, I am not speaking out of personal experience. G.
