MIT Cables ORACLE MA-X PROLINE BALANCED INTERCONNECT SIX METER -- REDUCED PRICE

Well shoot, let's try again . . . at a lower price . . .  
If you're using long speaker cables, please read on.

I'm selling my Oracle MA-X Proline Interconnects six meters (~20 feet) long.  I am the first owner of a dealer-demo pair custom made by Oracle for the dealer.  I've used them instead of long speaker cables between a Nagra preamp and an Air Tight power amp placed between the speakers, which has allowed me to keep the speaker cables quite short.  To my ear, this has greatly improved two things relative to short interconnects and long speaker cables: much greater bass slam and articulation, and dramatically better separation of instruments across a wider soundstage -- noticeable especially in the midrange, and irrespective of whether the source is analog or digital.

All the normal stuff: non-smoking, non-pet house, etc., and the cables are in excellent condition with all original packaging.  I don't think I ever got a manual from the dealer, but in any case I don't have that (of course, all you do is plug them in, set the attenuator by ear, and ignore them).

They cost over $15K new; I'm selling them for a reduced price of $4,000 (I'm somewhat mystified that I haven't had a taker -- these things really are pretty great).  I think they're a far better way to go than the reverse.  I don't need 20' cables any longer given some re-configuring of my system; otherwise I certainly would keep them.
Given the new price, please don't low-ball me . . . this is a super-great price as is, and I won't entertain (or even respond to) anything dumb.  Thanks!
