My BHK arrives next week and I will burn in with the Tunsgram PCC 88 for 200 hrs as suggested by many others.
The BHK is fitted with 2 pairs of outputs and 10 pairs of inputs. Trading of 2 pairs of XLR inputs for another pair of XLR outputs would have been nice for me.
I triamp with my present tube pre amp which is fitted with 2 pairs of XLR.
One pair of XLR feeds a pair of active subs 25 feet away, and the other pair feeds 4 channels of amplification via passive crossovers 6 feet away.
I am planing to connect the BHK with the XLR feeding the subs and the RCA feeding the other 4 channels of amplification.
If someone else have done this kind of setup pls chime in.
