For the Chicagoland area I would say Stereo Exchange is the best if you want it done right. I live in northwest Indiana and took my MBL preamp to David on my daughters word after her boyfriend had an old Concept receiver repaired. He said it worked great when David was done. She was right. The preamp preforms great and all the issues I had with it were repaired. It's not a fast food type store,David takes the time to make it right. Very pleased.
Looking for good repair shop in Chicago
I have a pair of McIntosh Mc 60's that need some help. If I had to guess, the coupling caps are way past their prime. I am looking for a good shop that could take care of this and whatever else these amps need. I am willing to look at anything in the Chicagoland marketplace including NW Indiana.
