It's nice to be able to start this thread off fresh. I just received my DNA-1 Deluxe back from SMc Audio yesterday after having the new Revision A Gold upgrade done. To the best of my knowledge, mine is the second amp to have this upgrade. Steve has told me that it is going to take a while to break in, but I can tell already that this amp is incredible. I can't stop listening to it. My wife(who I'm trying to turn into an audiophile) even commented that instead of feeling like she's listening to music, she feels like a picture is being painted in front of her. You really do get the sense that the music is just there. In addition to the normal Rev A upgrade, the Gold included a Plitron Transformer, Black Gate Output Bypass Caps, WBT RCA Input Jacks, Soft Recovery Diode Bridge, Cardas Deluxe Binding Posts (2nd pair), and Musicoat Component Treatment. An option of balance inputs was available, but I did not have this done since my preamp doesn't have balanced outputs and I don't plan on replacing it. The amp was sent back to me in a crate and was in perfect condition. Besides being totally happy with the upgrade even at this stage, I can't speak highly enough about both Steve McCormack and Kris Jeter of SMc Audio. They were great to deal with and extremely helpful. I did this level of upgrade based on my trust in them and have not been disappointed. I highly recommend it to anyone considering it.
McCormack SMC Audio Upgrades
I am considering purchasing an older DNA 0.5 or DNA 1 and having it upgraded by Steve McCormack. Is there anyone out there that has had experience with the upgrades and would like to share their thoughts? I am particularly interested in the sonic differences between Rev A and Rev B. I would also like to know if anyone has upgraded their TLC and the effect that it has had. Thanks in advance for the wisdom.
