Interconnect recommendations

Who is Amy? Seriously, nobody can help you here. Selecting cables is system dependant and of course subject to your personal taste. Try The Cable Company's cable library. They also have used and demo cables if you are looking for a deal.

I like Zu as well. They are very low in capacitance, yet tonally well-balanced and not aggressively bright.

I will look into these, thanks. The $400 max is flexible and included looking at second-hand goods. As for Amy. Doesn't everyone know her?

Mogami 2549 with whatever connectors you want makes a great RCA cable. Go 2534 for balanced. You can have some 2549 made up at Pro Audio LA (not affiliated) for less than $50.

I'm about to hook up Purist Audio Museaus to my Simplex. I'll post my findings next week. I loved these cables in my old system... assuming they'll be great in the new one too.
