Which Audio Interconnect would you recommend?

I'd go for Canare's and spend the rest on good filtration and cryo'ed/gold plated outlets.

If you still insist on silver cabling I'd seriously consider the entry level Ridge Street Audio cables. They use natural insulation instead of plastics...

With silver, your system better be tight and dialed in. Your vibration control, acoustics, power filtration must be right on. If solid state components are used, they must be non grainy, non fatiguing. I use silver ICs (Ridge Street Audio MSE) and silver plated copper speaker wire (Mil spec)in my 100% solid state system but everything is tuned & dialed in. I blew my main class A amp (Forté 4a) and am using my sub amps to drive my mini-monitors. Them Kenwood monoblocks are sounding fatiguing. The system is revealling the amp's weaknesses. It boils down to that...

Keith, it's *you*, talking about $$$. I have something for you...get a hold of a Channel Islands passive preamp ($249) and compare it to your $4K Presence. You're going to cry...

Punchy, detailed & robust copper = Rhapsody II's by Straightwire. I won't sell mine...
