What pre amp matches the McCormack DNA 0.5

TLC and AudioSynthesis come with remote control. Placette has it optional and extra $$.
Passive is better than tubes and ss together IMO if possible and in your case you won't need any active one.

I recently paired 2 DNA 0.5 dlx's with a VTL 2.5 and am quite please with the sound. The high gain of the 0.5's is not problem at all with this particular pre-amp.

I'm pairing my DNA-1 deluxe with a Conrad Johnson PV10. The system isn't all together yet, so I can't tell you personnally how great it is, but I've seen a lot of support for this Tube-pre and SS-amp combo on A'gon threads. Something to consider.

I run a DNA-1 with a PV10al & absolutely love it. When I do upgrade it will only be to another CJ pre-amp. I can't imagine getting rid of the DNA anytime soon.

I've had the best luck with Spectral. The DMC 12, 20 and 15 all worked well. I listened to passive contral, as well as audio research and Spectral was the best fit
