| McCormack DNA 0.5 vs. Parasound HCA 2003 Hello again Tim -Reading your follow-up comments makes me think that the problem may not be clipping or specifically power-related after all. Apparently your LP listening via the PV5 is "warm and beautiful," and this suggests that the amp and spea... | |
| McCormack DNA 0.5 vs. Parasound HCA 2003 Hello Irish Tim -The DNA-0.5 does a fine job with most speakers in most situations, but it does have its limits. Your comments offer some useful clues as to what the problem might be, and it is possible that the DNA-0.5 does not have enough power ... | |
| McCormack DNA-750 The DNA-500 and DNA-750 monoblocks are fully balanced, fully differential designs. The inputs are transformer-coupled which allows (among other things) the use of both balanced and unbalanced input drive.Best regards,Steve McCormackSMc Audio | |
| McCormack DNA 500 vs DNA 225 upgraded Hi Stefan,Like the DNA-500, the DNA-750 monoblocks are fully balanced with differential outputs. The input is transformer-coupled using the same circuit as the DNA-500. Input impedance is 10K.Best regards,Steve McCormackSMc Audio | |
| Protect LED on McCormack DNA HT1 wont go off Fuses. Sounds like you have blown one or more of the internal 4A rail fuses. Replacing the blown fuses should get you back in business. Refer to your owner's manual for more information, and contact me directly if you don't have a manual.Best rega... | |
| McCormack DNA-1 runs hot Hi Papazeze,Your description of the warmth of your DNA-1 sounds completely normal. The DNA-1 runs fairly warm, but you can leave your hands on the heatsinks easily. And as you point-out, it's only the heatsinks that get warm, just as it should be.... | |
| Mccormack DNA-1 describe the sound characteristics I certainly appreciate the plug for my upgrade services, but dvdgreco needs to get his system basics working to his satisfaction before he thinks about having work done. A stock DNA-1 sounds quite good, has plenty of bass depth, power, and punch, ... | |
| Is age bad for solid state amps? Is aging a bad thing? Well, yeah - I have swelled-up and I leak a bit now and then. But I can still boogie, baby! | |
| Good tube preamp for McCormack DNA 500??? Hello Shoff -I hope you enjoy your time with the DNA-500. It is a fine amplifier, and happens to be an extremely good match for your Aerial 10-T speakers. Don't worry too much about finding the lowest-possible output impedance preamp. You do need ... | |
| McCormack 225 preamp match "Would a McCormack preamp give me a completely different presentation?"The answer to your question is yes, I am sure it would be very different. Probably better in some respects (definition, transparency, bass depth and control, etc.) but you woul... | |
| Help? Possible problem with my McCormack dna-125. The RLD-1 volume display reads actual attenuation in dB, so 0.0 is unity gain (output voltage equals input). Given that 2VRMS is industry standard for max output level on most CD players and the input sensitivity for the DNA-125 is 1V for full out... | |
| McCormack TLC-1 Deluxe Remote A relatively small number of remote-controlled TLC-1s were built late in its production life (around the mid-'90s). I am not sure what the numbers actually were, but no more than a few hundred were built. On the other hand, when the decision was m... | |
| Quad 405 Updated .... Any Knowlege on this upgrade I suspect you would be pleasantly surprised by the performance of the upgraded Quad 405 (and I oughta know - I'm the guy who started modifying them back in the late '70s). I also expect that you would get a lot of "bang for your buck" compared to ... | |
| Temperature of McCormack DNA-1? The trick is to keep the air moving through the enclosure so that heat will not build-up. What you have proposed should work fine, but you might get better results by positioning the fans to pull air in on one side and push it out on the other. Yo... | |
| McCormack DNA-1 vs DNA-125 All DNA-1 amps deliver the same power. The DNA-1 was originally rated conservatively (by me) at 150W per channel into 8 ohms. We later revised the spec to reflect the true power at clipping - 185W per channel into 8 ohms (continuous power, both ch... |
