I have used them in several systems over the years, both speaker and ICs. Not currently.
Cable optimizing is very system dependent, but antis are uniformly very clean, wide range and open. I find the SCs can be a little lean tonally in some systems, overall I like the ICs a bit better. Physically stiff.
A good candidate for the $, they do a lot of things well, but there are marginally better, usually for more $. Ultimately system matchups are key, but that takes a lot of trial and error to get right when it comes to the nits.
Enjoy!
