Speaker Cable Advice Needed

I have a lot of respect for Aragon. The 2002 sounded great on my Quad 988's...

Recommendations, without being able to hear the system nor really knowing what the person asking likes and doesn't, are always tough and of limited use. I like to read between the lines. If you had written: "the Aragon just blew the Adcom away" or "I didn't really hear much difference", then I would say don't bother trying different cables. But, you described what you heard in a way ("quite beautiful") that tells me that you are probably a sensitive listener and can appreciate subtlety; it tells me that trying different cables is probably worthwhile for you. The difference that cables can make is very real; and even the +$1000 cables, in the right system, is not hype. For $200 you can definitely try a few different things that can maximize your system's potential. For your gear I like the solid core suggestion (can sound grainless and beautiful). The AntiCables are a great place to start. Good luck.

The Emotiva X Series cables look, feel and sound great. I got one for my center channel.

DNM Stereo Speaker Cables...these bested many speaker cables costing many more times their humble price. If musical truth is what your looking for these will suit you just fine. They have for me for a few years now.
Enjoy
