Switch all your cables to OCC single crystal copper or silver but the copper is half the price and the improvement will amaze you, also getting Townshend podiums to put under your speakers will get rid of any vibration which destroys your sound, they isolate down to three hertz, not cheap though but definitely the biggest upgrade you'll ever do to any system.
Help me pick some new or used speaker cables
Let’s say the budget is $2.5k
Speakers are (modded/upgraded) Chapman T-7s driven by a Rogue dragoN.
The T-7s have titanium tweets-which I might like to tame or smooth ever so slightly.
I listen to Qobuz exclusively, lots of Rock(Zeppelin) & house (Satin Jackets) Female soloists (Norah Jones)
Thank you audioholics!
