s.s. preamp matchup to mccomack dna1 rev.a

Big: Craig's suggestions are worth trying - synergy issues are often simply a matter of finding the right cabling. Also experiment with different upgrade AC cords; no two sound the same. It's sometimes easier to tune the equipment that you have thjat to replace it. Find the right cables to get the sound that you desire. Other tweaks: cones footers isolation shelving can all be used to good effect regarding the issues that you mention.

what about an old McCormack TLC1? There was a synergy going on there when I heard them. Right now, I use a Purest Sound Systems passive control unit with a DNA 0.5, and I'm happy with the match. Before doing anything, I say take Garfish's cable/IC suggestion. I've considered dumping components before when ICs, speaker cables were the issue.

I'd check your cable compatibility also.I use my DNA 1 rev A with a Pass Labs Aleph L with fantastic results.

If you're not after embellishment you might do well to check out Placette preamps--very, very transparent and reasonable if you can go passive.
