Quad makes great gear. I have auditioned their new stuff, including the 22L2s, and I was very impressed with the sound. The styling of their gear looks a bit odd to me tho.
I read that the Touch has a very good DAC already; that Emotiva unit I suggested above might only change the sound, not improve it.
I am a big fan of component pre-amps, I think they give the music something more than a digital volume pot attached to a DAC, but YMMV. That is the route I would go, a component pre. For me, a remote is a must-have. There are not all that many decent pre-amps out there for under $1000 that have remotes, look at Parasound and NAD to start. My dream pre is a McCormack right now.
Anything you add will change the sound, whether its an improvement is up to you.
