So here's an interesting one...perhaps someone has an idea of what's happening and why.
System about a month ago....Turntable --> Aesthetix Rhea Signature phone stage --> Primaluna Dialog Premium integrated --> Focal Kanta 1 speakers
A couple of weeks ago, in starting to move from an integrated to separates, I bought a used ARC Reference 6 preamp. That now sits between the Rhea and the Primaluna which is now just acting as a power amp.
The ARC is a beautiful piece and I love it but I have noticed some peculiar results. When I play Steely Dan's "Turn That Heartbeat Over Again" from the "Can't Buy a Thrill" album, the vocal on the line, "Now the food here ain't so good no more" are greatly recessed, as in barely audible. There's another line that has a similar result but otherwise all is fine.
My turntable has two tonerarms / cartridges and the result is the same with both. I also have two different pressings of "Can't Buy a Thrill" and the result is the same with both.
When I remove the ARC from the chain the line is back to normal. When I stream the song from the Wiim Pro --> Gustard A22 --> ARC --> PL it sounds fine and normal.
I've noticed some other odd interpretations of albums as well but this one definitely seems to be the most pronounced. What am I missing here? Any thoughts?
Thanks for your help.
