wilson

I own Watt Puppy 7's and I currently use a CJ 350 premier amp and 18LS Pre Amp and the sound is great but only at higher db levels, I'm looking for more lower volume detail. I've heard that Pass Labs is a good combination with Wilson, so I was considering an XA 30.5 and I'm not sure if it's enough amp for these speakers? Any suggestions would be appreciated.
