I had this pre a couple of years ago...my first tube experience. I has a very lively
sound but a bit rough around the edges. I used it with my IRD monoblocks but
after awhile decided to look for something more refined. I tried a passive pre then
moved to an ONIX SP3 integrated which I have now. Also, I found my ACA
unfriendly to tube rolling. It only liked the cheap Sovteks. That's not so bad unless
you like to experiment which I do. Hope this helps...
