I completely understand what you are talking about, but just to be clear The Truth is not a passive preamp, it is an active preamp with no gain. About 6 months ago I sold my (2) Power Sound Audio V1801’s subwoofers and ain’t nobody more of a bass head than me.
A couple days ago I picked up some cables to run the subs off the mains and its much more involving. So, in reality I don't need the 2nd outputs anymore. haha.
Oh well. I'd be happy if I could figure out why my current preamp eats tubes or if I am just the unluckiest person buying tubes these days.
Thanks
