Morrow MA3 interconnects

I purchased them used from a third party, They could need additional time, I also own KCI firefly IC and they do many things well but I prefer the top end of the MA3's. I will keep listing and see what happens.

Try the MAC Ultimate Silver. You can have them burned in prior to recieving them. They will cost you below the $300 budget new.
I've tried just about every cable and these cables with the pure 5 nine silver is really very good.
Another good cable for bass is from a new cable maker called, Amadie cable try the Barb Masters, they also have very nice bass.
I always thought that copper cables had the best bass, but it seems high quality silver that has been soft annealed have better deep quality bass.

Equipment:
Portal Panache Int.
Arcam FMJ23 cdp
Soliloquy 5.3 Speakers

I also have the MA2's w/about 350 hours on them with exceptional bass driving Klipsch Forte 1's.

My MA3's from dac to pre are outstanding(single ended). I would contact Mike Morrow and discuss this with him. I find them to be very neutral after long break in.....
