One amp was popping at least every hour and has since I got the D600, even after a repair the popping soon returned. Then one amp was dead and so I sent both off for repair which this time seems to be an improvement and the popping absent.

I can't recall running them at a high volume since I got the D600 but I have always lowered the output to the D600 compared to that the M1 from the control panel of the Terratec. I can push the control panel higher but then get distortion.

Having got both amps repaired and sounding much better I tried to run them at higher than normal volume level and can not get to that floor bouncing earth shaking level that forced them to switch off to protect the threshold of hearing. I have run the M1 just below the level that they cut out with the cannons of the 1812 and the Firebird suite on LP. These levels are not comfortable in a small house.

I am happy with the quality but just puzzled by the lack of punch at higher volumes and don't know if it is the speakers or the 101b output.
