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,

Try listening without a conditioner. You might be pleasantly suprised.Just a thought.
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.
