Thanks to the members who responded so far.
To Jafant, the somewhat questionable cable in the mix is:.... the Nordost Red Dawn from probably vintage 2007. At the time it retailed for $400, and I bought it for $200 in 2012. Nordost is notorious for overpricing and cable that can be lean or somewhat bright. The Red Dawn IC I have is surprisingly neutral and detailed with some tinge of brightness ( but that is problematic to other variables)
I only have one or two other IC cables in my corral worth trying; and, that is a Chord "Chamleon" which really made a difference with my previous CD player, the Rega Apollo. I have a set of balanced to RCA adapters, but I am not sure if that is going to provide the same synergy of the balanced outputs on Ayre's integrated or separate pre-amps. Nevertheless, I shall keep you posted.
