I had a full loom of Aluminata about 7-8 years ago. I had power cables, speaker cables, and RCA and XLR interconnects.
I think they are low priced for what approaches state of the art performance.
It was the first cable I demo'd that left me in awe of what was possible with cables.
That said, in my system, I eventually found them a bit tipped up. I didn't really have full range speakers at the time and that probably played into my impression of them.
I sold the JPS and moved into Wireworld Platinum Eclipse 7 interconnects/speaker cables and Furutech power cables which gave me a balance that was more enjoyable at the time. I think the JPS Aluminata outperforms those in terms of neutrality and a detailed presentation but like I said, my system was probably too bright at the time to enjoy them, long term.
I do believe Audioquest Dragon/WEL interconnects outperform all of those at a significant increase in price, however.
JPS Aluminata is worth an audition, in my opinion.
