Any reccomendations for amplifiers for my Quad 988


My system is:
PS Audio power plant
Cary 303/300 CD Player
SAS Audio 10A preamp
Quicksilver V4 Mono Blocks
Quad 988 speakers

I find the the sound gets congested when listening to large scale orchestras. No issues with vocals

I heard them sound very nice (superbly defined 3D images of instruments in there own space) with Conrad-Johnson amplification (in a store demo).
I am using vac 70/70,s with 989,s and they perform very well.Have you listened to both output taps?Are the Quicksilvers plugged into the power plant?I tried one of the latest ps plants and it helped the cd player but created congestion when either of my phono stages or line stage was plugged in and the power amps into the ultimate outlet was a disaster.Several people that have posted here are using amps with less power than yours with Quads and are happy,Mike Sanders has been building amps for a while why not e mail him.
I have been a quad owner for over 20 years and I now own the 988's.Even if I win the lottery today,Quads will always be the one and only reference for me.I have used many different tube amps,including single-ended and Otl's but I have found that the KARAN solid state electronics from Yugoslavia works best for me(tube sweetness,grain free,with lots of controll)and I dont have to worry about playing with tubes.Your Quicksilvers are good amps.I would get rid of the power-plant.I use the Sound Application line conditioner plugged into a 20 amp line or you could use the Shunyata Hydra.Keep in mind Quads dont play very very loud,and in a room thats not too big I dont hear any problems.I also use a pair of Rega Vulcan subwoofers with my Quads and I have my speakers mounted on Sound Anchor stands 12 inches off the floor.The sound really open up because the Quads are much more relaxed with the subs.Stay in touch.
