best remote preamp for McCormack amp

Yeti; If you're willing to consider a tube pre-amp, I've used the Sonic Frontiers Line 2 with a McCormack DNA-2DX for over 2 years, and then with the DNA2 up-graded to Rev. A for about a year now. I highly recommend this combination, and I also have an SF Line 1 that is nearly as good with McCormack amps. These are tremendously versatile pre-amps with excellent remote controls. They are neutral/accurate and very smooth sounding rather than being euphonic. Line 1 and 2 pre-amps are available used for $1000 to about $1700. Good Luck. Craig

If you can find a Golden Tube SEP-2 or SEP-3 linestage they make a very nice matchup with McCormack amps & have remote control. Gigantic sounstage!

Frontiers preamps. Even the least expensive line 1 has the same build quality and features as the cost-no-object (almost) line 3.This is a feat in itself. Full featured yet musical. Not your typical tube sound, but very exact and neutral, the way it should be ! I own a Line 1 with the McCormack DNA-225, I have looked hard to get the perfect match. After auditionning the line 1 and 2, I got a line 1, springing instead for the valvo tube upgrade. It captures the qualities of the McCormack amp nicely. Good luck! Hope this helps. Very nice built-in tube headphone amp by the way.
