Checked with Posthorn, Redding, and Vark. The MK is $296 from you vendor of choice. Redding only had one in stock and Vark was out of them.
And thats for a SINGLE MK collette cable to connect to the mkxx caps, correct? Some of this is slightly over my head. But iVE NEVER been too good w tech specs. Just give me the damn gear and I'll pull a smokin tape with it tho So how much would a KCY>PFA cable cost
Correct, that's aprox $300 for a single channel. $600 for a pair, the PFA is like $80
each. It's not cost effective to build your own active cable, never really has been compared to what Vark does (which is essentially build it for you). The advantage that i see is that you get a balanced connection or a different feature set, not a price break. You already own a KCY, just get a PFA to put behind it if that's something your interested in, and read up on the polarization voltage differences.
What hi/lo is proposing is chopping a set of KC5s into 2 pieces, and put the PFA in the middle and not use the body end, or just having the collettes > cables (not together) > pfas.
