Thanks!
I wouldn’t rush to swap for pass. Hegel is good. Different but good.
Back to your findings…
UNBAL 2 RCA Output 2.4 V RMS
BALANCED (asymmetrical output) 2 XLR Output : 4.8V RMS
what you’re hearing is due to higher output via XLR outs of your dac and that gives your lower noise and the more weight you’re hearing in the presentation is your dac driving the amp better. I always use XLR where possible.
Rhodium plugs take more than 72 hours to burn in. Are they made by Furutech? I would connect some source to the dac that you can spin 24/7 for at least one week while your hegel amp is on but on mute at times you are not listening. don’t turn anything off let it run.
Power cords on dac and amp will be critical.
