What are the cap values? Some are QUITE large, and replacing with, say, TRT D-Caps would cost hundred$.
Personally, I've been very satisfied with NorthCreek Zens in large values--they seem a little smoother than, say, SCR/Solens/Axons--with TRT D-Caps as smaller values and bypasses on the (larger) NCs. But the SCR/Solens/Axons are unbeatable in quality v. performance, especially in large values.
