I have been using my ARC SP-15 preamp for about 9 years now. I am very pleased with it. The phono section has good bass and sweet highs and it has great flexibility with switchable impedance loading.
In 2004 I sent it back to ARC for a check-up and they recommended freshening it up by replacing all the electrolytic capacitors in the Power Supply section. I did and so I am good for at least another decade. It has always been a very reliable preamp.
I think an integrated phono section is better than a separate box, but I use the balanced outputs to my Amp and I sometimes think about trying a fully balanced preamp with my CD player just to hear the difference. But with one son in college and one in High School, that experiment will just have to wait.
