Hello again! New to the forum and hoping to get help from the experts and be better educated. I have approximately 500 vinyl albums most from the 60 and 70's and all in excellent condition. I have a Cambridge azur 840A integrated amp, 540P preamp, Music Hall mmf 5.1 turntable, Vandersteen 1B speakers and Bowers & Wilkins DM602 S3 speakers and NAD CD player. Two days ago I turned everything on and there was faint and minimal sound. I continued turning up the volume and at the upper end started to hear intermittent and crackling sound. Did this several time and then received a DC ERROR message. I pulled the power cord immediately and then saw in the azur manual that the unit has a built-in DC Detection that also protects the speakers if there is an internal fault but it also says that the DC detection might appear if there is hard clipping. Given I had the volume almost at full I am assuming this was a hard clipping issue. I have tried to contact Cambridge Audio but no response so far. Has anyone experienced this issue?
Also, if the azur is shot and I am looking for something with 100w at 8 ohm, which amp would you recommend of the Cambridge 851A, RA1572 or NAD C 326BEE?
