I have bragged about those yellow caps as state of the art, and they were in their day
Oh, no! Time to remove the radiator again? Lol
I do occasionally wonder about different bypass caps on the CSA coax feeds. We went with Multicaps but, in hindsight, I’m curious to hear something like the Audyn True Copper Max or Jupiter. Likewise, wonder how the Path Audio resistors better the Mills MRAs, if at all. Then again, that was a lot of work to make one change in one channel, wait for it to burn in, and carefully compare in mono.
Maybe I’ll just listen to music and be happy rather than compulsive?

With the 3.7, I wonder if Rob Gillum’s experience is related to those massive ELs which cannot practically be upgraded due to size and cost. But, yeah, the Mills seems like low hanging fruit that is likely to make a nice sonic upgrade and for not much money.
