Using McCormack DNA-0.5 Deluxe as Mono Amps

Steve: Thanks for your input and explanation. It is clear and easy to understand. Your warning is taken, and I will heed it!

I ended up acquiring a DNA-1 Deluxe through Audiogon. Hooked it up to my TLC-1, DAC-1, and SST-1 transport. The DNA-1 Deluxe is larger in life than in the photos. It weighs a ton too.

Alternating between B&W 803S and Energy Veritas V2.4 speakers using bi-wired MIT Terminator 2 banana connections, I have never heard these speakers play so good. I am very pleased with the results. I have no regrets getting the DNA-1 Deluxe.

If the upgrade bug strikes you could acquire another DNA-1 Deluxe and do the passive vertical bi-amping described above. I did this with my Vandy 3A Sig's with awesome results. I'm anxiously awaiting the return of my TLC-1 from SMc Audio, its in for an Ultra Plus upgrade along with my Micro Phono Drive. I will let you know how it turns out.
Just out of curiosity which output are you using or have you tried both and what did you think?

I have not thought of using two DNA-1 Deluxe amps. I might just try it in the future.

I have read owners' comments about their preferences. I tried both passive and buffered outputs and I have to admit that both outputs sounded good to me. Currently, I am using the passive output to go to the DNA-1.

I also have a pair of tube Rogue Audio Magnum M-120 mono blocks amps hooked up to the buffered output of the TLC-1. I would occasionally switch the B&W 803S and Energy Veritas V2.4 between the DNA-1 and Magnum M-120, depending on my mood.

Thanks for the reassurance of your explanation. Will be trying passive vertical bi-amping with two Bryston 4B SST's and KEF 207's. Hoping the only fireworks are sonic!
