Time to upgrade my PS Audio Quintet

I'm thinking about going up to solo crystal oval 8, have you compared the two? Oval 9 and oval 8?

I have not tried the Oval 8. I bought the Oval 9 based on recommendations from AudiogoN members.

thanks for sharing, i thought both were great cables, probably more refined with oval 8(from the review i read), hence i ordered oval 8, i've been auditioning this swedish cable called supra sword(their flagship cable)they are really good cables, it's like listening to vinyl, so organic and coherent, and tons of details, and it's copper stuff.
just my two cents

What powercord is on the Quintet? as it affects overall sound. I first tried an older plus cable and found it to grainy as well ,I then used an Statement Sc and the grain is gone, I plan on trying the new AC-10 or AC-12 which is on my Amp at the moment, the cable change alone will work.

Allenjohns, you may want to consider the PI Audio Group Majik BUSS filtration system ($595). This thing performs as advertised; and it works well with existing conditioners. Check their website for details. There is also a little bit of information here on A-gon, but more on Audio Circle. Since you have some room in your budget, you can get Dave Ellege, PIA's owner, to work with you to build something custom for your set-up. I had Porter Ports installed on one duplex to go with the standard outlets on the other side. Dave's a nice guy and he'll give you a 30-day audition.

In my case there was visual proof that it was cleaning up the power in my listening (family) room. I have some PS Audio Noise Busters in place. Prior to installing the Majik BUSS the Noise Busters would sometimes blink like crazy depending on what else was going on in the house ... plasma TV running, clothes dryer, refrigerator, light dimmer operating, etc. As soon as the Majik BUSS was installed these NB's went dark.

To further clean-up any remaining artifacts, try the Audio Prism Ground Control spades. They're $150/pair from Music Direct, and definitely a worthwhile tweak.
