Well thanks OP for a very helpful thread. I’ve had an A23 Hommage T2 for several years now but I’ve always found it underwhelming. However I was using it with .5 meter A23 interconnects (and a Kuzma 4 point on the inputs). I had the intuition that the A23 ICs were over-damping the signal but I never got better results with other cables (all of them ‘interconnects’ too).
So I got re-inspired by this thread. As it happens there was a used pair of Kimber TAK cu phono cables available at a reputable shop near me. Apparently they have a capacitance of 47.1 pF in the 1m length - the ones I bought are 2 ft long. I swapped them in for the A23 ICs and sure enough I found a significant and positive improvement. Everything opened up, top to bottom, and now the T2 finally makes sense to me. I’m using it with a newly rebuilt EMT JSD 6 cart and will swap in a new Zu Audio/Denon 103 shortly. Very nice to get the value out of the T2 after all that time.
