@agbrace What do u mean u hear a chime ? Can u explain that chime sound you are hearing coming through the speakers? I have owned the Ref 5se , the Ref 6 and now the ref 6SE. I was using a Krell FPB 600 amp now I am using the Audio Research Ref 750s. I have NEVER heard anything but dead silence

OP/geof3 - I use a Ref3 into a Threshold S300 II, which is fairly low gain, but I've never ever, even with my old amp which had much higher gain, heard any kind of 'chime'. I've even just 'thumped' on the top cover to cause some vibration, and, silence, even with the volume at 50, which is around my normal listening position (range from 40→60).
When you say you hear a click of a relay when you turn the volume from 0 up; that's another thing that absolutely doesn't happen on my Ref3. Going from zero up, it's silent, completely, even with my ear next to it, there's nothing. Relay operation can only be heard when changing sources, never from Vol-0 up/down or anything in between, so if your makes a relay clicking sound when going off of zero, then I would do as suggested and send it to ARC for repair
And, geof3, the Ref 3 absolutely does not have a variable gain setting, as you say, either on the remote or the unit itself.
Hey, I am not sure how physically close to an ARC dealer you might be. Try borrowing a Ref 6 or even better the SE version and hear if it happens with the demo. I have the 5SE with the Luxman M10X. I bought them in that order. Maybe your 6 does not match the H20. But the 6se might. The impedance or the voltage is different. I will tell you I not my friend who has a similar setup (both SE) have had this issue. I say borrow the demo from the dealer and email ARC at the same time.
@tattooedtrackman It sounds like a small high pitched cymbal hit due to the vibrational shock of the relay transmitting via the PCB I suppose. It only happens when coming off of volume 0 when the relay kicks in.
