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

Thanks,

I have tried my main components with and without a conditioner. The amp sounds better plugged straight into the wall, but the CDP sounds better thru the Quintet. With the CDP plugged into the wall outlet, I hear the soundstage as images in my room. With the CDP plugged into the Quintet, I hear the the images in their room. What I mean is that I hear the musicians in the room it was recorded in. I want more of that. BTW, I would also be interested in feedback on something like an Oyaide power strip compared to a power conditioner.
I use the PS Audio PPP and am fairly happy with it. You might want to consider power cords with 6N copper. I believe the DH wire is OFC. This IMHO could reduce grain. I like Oyaide Tunami wire. Just a thought.
Something I found to make the greatest difference in sound was having dedicated "home run" lines put in for the system. If you don't have dedicated lines for your system, spend the money on a good electrician before you spend on conditioner. I also upgraded my service at the same time.
My first suggestion is to try a Synergistic research Teslaplex($95.00) for your wall outlet. Second, a S.R QLS 6 or 9 is nice with a Tesla T2 power cord. You will notice a huge difference with those three upgrades. Then plug everything into your QLS. Your amp into the bottom outlet of the Teslaplex. Unless it sounds better in the QLS. What cord do you use for your power amp??

Bacardi, my power amp cord is a DH Labs Power Plus.

Srwooten, what is 6N copper and how does it differ from OFC? Is Oyaide the only company that uses it?
