| MacCormack Upgrades from SMc Audio? Hi Mark -Thanks for your interest in my work. One correction: the $500 upgrade you describe is the Revision A - not the "B." You are absolutely correct that the Rev A is a complete rebuild, including circuit topology improvements as well as a full... | |
| Power Cord for my McCormack DNA-500 Hi Chuck -My comment was only intended to suggest that I think you would be better off without the adapter, once you have found the AC cord that is right for you. This is especially true with high-powered amplifiers. I am mildly surprised to hear ... | |
| Power Cord for my McCormack DNA-500 Greetings 'Goners -Just a thought about the notion of using a 15A-to-20A IEC adapter... I realize that the 15A IEC power connector is far more common than the 20A style, and thus it is easier to find 15A power cords to audition. However, it is my ... | |
| Is there a differenc between McCormack DNA125&225 Hi Ben954 -As you may know, the DNA-125 and 225 are based on the same circuit topology with the 225 delivering more power into a given load. Specifically, the differences in the 225 are 1) double the number of output devices (8 per channel instead... | |
| McCormack DNA-2 vs DNA-225 In fact it would take quite a while to catalog all of the differences between these 2 amps. Although they are based on similar circuits, they are quite different in execution. Briefly, the DNA-2 design dates back to the mid '90s, just prior to the... | |
| Need Info/Opinions of Mod Squad Duet Preamp Hello Rapid -I am out of town at the moment, but will be back in my office on the 17th. Contact me then and I will send you a copy of the owner's manual and answer any further questions you may have.Best regards,Steve McCormackwww.SMcAudio.com760-... | |
| Best preamp w/Tuner for McCmk DNA-500? If you don't mind taking a little time, why don't you take some photos and add your system to the "Virtual Systems" forum? I daresay that we would all enjoy seeing the result of all your work.Best regards,Steve McCormackwww.SMcAudio.com | |
| Best preamp w/Tuner for McCmk DNA-500? Congratulations on your capitulation to the VAC ;-) You have wandered some distance from your original goal, but you have sure wound-up in a good place. Have fun!Steve McCormackwww.SMcAudio.com | |
| A worse feeling than burning out your amp? From your description it sounds like you lost the ground connection through your interconnect cable, leaving just the "hot" connections on both channels. This will cause most amplifiers to oscillate, often resulting in damage to the speakers, or a... | |
| Best preamp w/Tuner for McCmk DNA-500? I just want to point out that preamp/tuner combos are fairly rare (I can't think of a single one at the moment) and limiting your search to this category will leave you a few options at best. If you are willing to consider separate components you ... | |
| McCormack Amp question Hello Ehoehn -Most of my amps have a 100Kohm (high) input impedance and are easy to drive with any type of preamp. The only amplifiers I produce with a 10Kohm (low) input impedance are the DNA-500 and the SMc Audio-upgraded amps that include my ne... | |
| Powercord for McCormack DNA 500 The DNA-500 (like the DNA-2) accepts a 20A IEC power cord. | |
| McCormack Silver vs. Gold revision for DNA-125? Hi Dawgcatching -I'm pleased to hear that you are enjoying your DNA-125. I just want to mention that it does not consume very much power at idle, at least relatively speaking. At something like 80 Watts, it uses less juice than many other high per... | |
| McCormack pres/amps and Steve's mods Hi Phd -I suspect you mean to say that your speakers are "bi-wireable." This simply means that separate inputs are provided for the high-pass and low-pass sections of the internal crossover network. To say that they are "bi-ampable" suggests that ... | |
| Best Pre-amp for the McCormack DNA-1 Deluxe My amplifiers typically have a 100K input impedance. The only exceptions are the DNA-500 and the amps I have upgraded as monoblocks or with balanced inputs. These amps have a 10K input impedance, as dictated by the balancing transformer.Best regar... |
