I have been running my 3 channel B22 (mounted on e22 board, and transfo and o22 in separate cse) for sometime now with my 701s and sounds great, just the slightest amount of hiss if I convince myself it is there. I recently got a pair of D2000s and hiss is much more noticable. This is on a e22 board mount and RCA ins are connected to the case (tried isolated and connected and made little difference). do not have the e22 board grounded to case except with standoffs. Any ideas on how to quieting this down? Any help would be greatly appreciated.Using TDK pot. Would it help to ground it to case other than with the holding nut? Have 2 RCA inputs tied into a double pole elna switch - so not switching grounds, they go striaght to input. Is that a problem? [Edited by rhester on 03-21-2009 at 01:55 PM.] |
