Using McCormack DNA-0.5 Deluxe as Mono Amps
Hi Morgandogge -There are a variety of ways to use a matched pair of stereo amplifiers to run your main speakers. There is no “Mono” switch on the DNA amps, but you can simply use one channel per amp (leaving the other channel unused), or you can ... 
Transient Attack and Amp Design
Jragsda, glad to hear you are enjoying your DNA-1.I came up with the DNA (Distributed Node Architecture) design specifically because I do believe that it is audibly beneficial to eliminate (as much as possible) the connectors and wiring between th... 
McCormack DNA500 and DNA2
It is difficult to write a detailed description of the differences between the DNA-500 and my Platinum upgrades to the DNA-125 or 225, so I'll keep this brief and encourage you to call me if you would like further detail.The DNA-500 is an outstand... 
McCormack DNA500 and DNA2
Hi Topsel -Sorry if I missed your e-mail question. I see that you currently have options here on Audiogon for both a DNA-500 and a DNA-2 LAE (limited Anniversary Edition). Both are fine amplifiers with a lot of power and either one might work well... 
McCormack SMC Audio upgrades: how good are they?
Hi Luigi -I now use Lundahl amorphous-core transformers in my amp upgrades (and in my VRE-1 preamp). I started with Jensen transformers, but switched a few years ago when I found the Lundahls offered better transparency. I originally used input tr... 
McCormack SMC Audio upgrades: how good are they?
Just a couple of additional comments if I may... A previous post alluded to the need for a solid-state preamp if you went with the further Platinum upgrade, and this is not strictly accurate. Your current DNA-125 Gold has a high input impedance (1... 
McCormack SMC Audio upgrades: how good are they?
Hello Chiho -With respect, I would suggest that you are barking up the wrong tree with your question. No matter what opinions are offered in response, the only opinion that matters is yours. It is ultimately up to you to decide the value or qualit... 
McCormack TLC-1 Output Jacks
Hi Morgandogge -I designed the TLC-1 preamp with buffered outputs (in addition to the passive outs) to increase its flexibility and system compatibility. The buffered output was designed to mimic the performance of the passive as closely as possib... 
Any info on the new Mccormack DNA 250?
This question has come my way several times recently, so let me take this opportunity to clarify...I left McCormack Audio about 3 years ago to pursue building my new preamp (the VRE-1) and to continue expanding the equipment upgrades I offer throu... 
Preamp for McCormack DNA-125 Gold? Budget $2k
Hey - whatever works! Glad to hear the Axiom is working for you. It's about as simple as a passive volume control can get (while still including "features" like a chassis), but if that's all you need for now, you're all set. I'll be happy to talk ... 
Preamp for McCormack DNA-125 Gold? Budget $2k
JP11801 - Brownsfan is correct - your DNA-1 Rev A Balanced has an input impedance of 10KOhm. This limits your passive choices somewhat - transformer-based designs (TVC) units are your best bet, and resistor-based designs (with conventional volume ... 
Passive preamp users help with McCormack Passive’s
Wendell is correct - you should contact me directly to discuss this. For one thing, it seems likely that you are connected to the active outputs - not the passive. Be sure you are connected to the passive outputs if that is how you would like to r... 
Do you leave your McCormack amps powered on 24/7?
Hi Bjue -I hear this question from time to time, but the answer is true for all audio gear. There is no question that leaving your equipment powered-up will keep it sounding its best and ready for critical listening at any moment. The downside is ... 
Help troubleshooting McCormack separates?
Good luck, indeed! We're still shooting in the dark here, but I would like to suggest that you look into an improved Earth ground arrangement for your AC system. Just a thought, but worth pursuing. (Yes, I recall that the problem showed up over at... 
Review: SMc VRE-1 Preamplifier
I just want to thank you for taking the time to post your thoughts and comments. I put a tremendous amount of work into developing the VRE-1, so it really means a lot to see that others appreciate the results. That someone with your depth of exper...
