Yep, I switched from the Hegel to another amp that I have, a Benchmark AHB2, which has an input impedance of 50k ohms and the chime was still audible but very much reduced such that one would not consider it an issue. Speakers are Harbeth 40.3XD ~86 dB Thanks for all the discussion and advice on this issue.

If it only chimes when getting out of zero volume, then I would try to set the volume to last used in the menu and before putting it in standby just lower it to 1. If my memory serves, it’s possible thru the set up menu.
Secondly, the Ref 6 has 15db of gain and you’re not only mismatching impedance with the Hegel amp but also, due to the high gain of the amp you’re limiting the usable volume range. It must be pretty narrow and each step increases or decreases the volume by a lot. Not a good setup.
Few other things that come to mind - make sure the Ref 6 has plenty of space around it. Place it on the top shelf if you haven’t yet with nothing above it. Allow it breathe. Are you using the rubber tube rings? If not, you should. Is it plugged into a power conditioner? Try it with the conditioner and direct to wall and see if any change in noise.
I have the same problem in the last 30 days.
I also have listened a noise coming from the transformer on the right just behind the volume dial if I put my ear very close to the acrylic cover.
Can you check if yours is also doing this noise?
Mine was perfect for the last 4 years and I am sure it is not normal. (Have change al the tubes for ARC grade Upscale tubes with no change).
@lcfpimentel No, other than the chime the preamp is very quiet. I do notice though after a few hundred hours on the new tubes and when they’re warm, the chime is reduced. Also it was much more pronounced when I was running it with the Hegel amp which has abnormally high gain.
