Onkyo m510 grand integra

I bought an M-510 in December. One of the channels was terribly distorted and the seller said cold solder joints were the culprit. A highly skilled technician in Williamsburg, VA found the ONE bad solder joint and repaired it along with turning down the bias. He said it was running so hot, an egg could have fried on top. Now, it's in my home awaiting hook-up. It will replace my M-508. Stay tuned for a report.

Two day old listing on US Audio Mart. Seller is in Scotch Plains, NJ and is asking $7,500.

The M-510 had no matching preamp. Onkyo made matching amp/pre-amp pairs up through the M-508/P-308. There was an M-588/P-388 that came after the M-510 and the P-388 physically resembled the M-510 with the champagne finish. The pre, however, had XLR cable inputs to match the M-588 and, of course, the M-510 doesn't have that hook-up capability. I am using a P-308 with the M-510 to match the "In Phase" circuitry that Onkyo pioneered at the time. So far, AWESOME results pushing FOUR sets of speakers: RTR 280-DR, RTR ESR-15 electrostats, RTR DR-1 "Dymistatic" electrostats, and Synergistics S-53. One quarter volume is all my house can handle! READY TO RUMBLE!
