We're getting back into the equipment purchase biz after 20 years. I have a pair of KEF 107 spkrs to start with and want to add amp/preamp, cd player and squeezebox (or like) to make a system. Our old system was a Mac C28 preamp, a Mac 200 watt amp, and an NAD CD player. Sound quality was fine. Any thoughts besides reading reviews? Anywhere in the Sacramento area We can listen to alternatives?
