Yesterday my amp mysteriously became extremely dark (hardcore basshead) for the entire several hour listening session, then the next day restored back to the same very musical, detailed robust sound that I tuned my system for. I know it was the amp because when moving my same headphones with same source chain / same song back to the DAC's built-in amp, I got a linear sound once again. This precludes any change of my hearing, DAC, DDC, source or power chain to it. I thought it could be one of my Odin Gold AC cables towards the end of burn-in, but it seems less likely being that the only shared circuit between these and my current amp are with the one running to the central power conditioner which is already burned-in for around 500 hours, and the other going to the DDC. It may have been related to its' copper tape shielding but that doesn't explain anything how it's back to normal today and very indirectly connected.
My current amp is a Kenwood VR-406 integrated speaker/headphone amp which has a fixed 2-prong power chord (while my tube amp is out for repairs). I think either the Aliexpress RCA damping cylinders, or more likely: the 10 assorted RCA caps are responsible for such fluctuations, below. Again no issue for now being everything returned back to normal - just wondering about any opinions.
I'm actually thinking to try even more RCA caps being that the recent tinned copper braided metal wire shielding of the wire between my grounding box and DDC actually made my system somewhat darker, and the caps tend to add treble.
