Just completed the system. Will provide feedback soon.
Owing to the amount already spent, the only upgrades in the system could be replacing the nterconnect and speaker cables with Kharma Grand Reference cables and that will be the end. I work for a living and have to stop somewhere.
I am guessing that the Audio Aero Cap is the CD player? Does it have its own volume control because I don't see a pre-amp in the chain, unless the KR EntVT-8000 is an intergrated amp.
