High level, this is the first system I have created where I can honestly say I have soundstage moving outside the speakers. Pretty spooky but highly enjoyable.
I have significantly reduced electrical noise with the incorporation of JPS Aluminata interconnects. They dropped the small nagging hiss from the tweeters to barely detectable. To explain, at 18 inches from the tweeters, my ear could pick up a small electronic hash before the Aluminatas. Now I can barely hear some hash at 6 inches from the tweeter - with my good ear!
Previously owned Sasha 1's and the Alexia 1's are really surprising me with the bass they have, especially exposed by the Aluminatas. I never really had an issue with the inverted Focal dome on the Sasha's, but the dome of the Alexia's is much smoother and blends in very well. I was always so appreciative to have owned the Sasha's. I am amazed by the Alexia's.
I removed so much noise with the Aluminatas, I decided to pursue power cables more seriously. I have never really gained much in the sound department before with AC cables. Now I have gone another step up and am really digging the Tara Labs and NRG cables. I'd like to swing an Aluminata power cable later this year.
