@thr1961 ,
I can understand your dilemma. I was out of the audio loop for 30 years, until I had the funds to re-pursue my audiophile dream.
If I were you, I would try to find other Joseph Audio owners. Perhaps JA has a forum?
I own Vandersteen, and have come to learn there are certain combos that really work with those speakers. I would expect the same with Joseph Audio.
As far as cable go, I was a naysayer, but after listening to the newer Audioquest models, I was definitely a believer. Unfortunately, as you have discovered, this 'finer' listening came at a cost. So, my workaround is to buy the model or two below the newest model when they came up for sale used. Eventually, that 'new' model will be up for sale used, but at least I am buying it for 50% or so less.
