Time to upgrade my PS Audio Quintet

I currently own a PS Audio Quintet and while it works well, I am hoping to find something that adds more transparency and reduces grain. My primary components are;

Exposure 2010S2 Integrated Amp
Sony SCD-XA5400ES CD/SACD Player
Dell Laptop / Wavelength Proton DAC
Spendor A6 Loudspeakers
Analysis Plus Interconnects and Speaker Cable
DH Labs Power Cords

I have the Exposure plugged straight into the wall and everything else into the Quintet. As I mentioned above, my main goal is to take the edge off the system. While I care about frequency extremes, they are not as important as a natural, transparent, uncolored midrange. Anyone who's used a Quintet and moved to something better, what is it? Around $1500.00 or so is my budget.

Products I am considering;

PS Audio Power Plant Premier
Shunyata Hydra & Guardian
Synergistic Research QLS 6 & 9

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.
