| Passive Bi-Amping with Different SS Amps Hello Daltonlanny -Kr4's answer is essentially correct - you need a way to turn-down the input level on the higher-gain amplifier to match the level from both amps. The gain difference is only 2dB, but this is still enough to throw-off the coheren... | |
| McCormack DNA-125/225 Upgrades Having read the various posts here, I felt I should weigh-in with a few comments of my own. First of all, the whole point of McCormack Audio is performance *value,* while my personal goals with SMc Audio are oriented more toward absolute performan... | |
| Mccormack DNA 2 vs DNA 225 Hello Ajpat -All my amplifier designs share the same pedigree, so there are inevitable similarities. The DNA-225 is a newer design, so it includes a variety of improvements developed since the DNA-2 was created. On the other hand, the DNA-2 is som... | |
| Speaker suggestion for McCormack DNA 225 DLX Hello Brquebral,I would like to point-out that I have designed my amplifiers to operate properly with the broadest-possible range of speakers, and your DNA-225 should do an excellent job with your Martin-Logans. Having said that, it is also fair t... | |
| What is the best amp for a Mod Squad Pre Amp Hello Teejay -I hope you enjoy your Line Drive and find a good amplifier match for it. When looking for appropriate amps, keep the following general recommendations in mind:1) Look for a fairly high input impedance - around 47Kohm or higher. Anyth... | |
| McCormack DNA amp options.... Hello friends -Maggieowner is correct - the Plitron toroid transformer upgrade is now available for the DNA-0.5. The cost is $450 when done as part of an upgrade. While this transformer makes a very nice improvement to the DNA-1, its effect on the... | |
| McCormack DNA-2 DLX balanced input impedance Hi Bundy -The amp should be off for this test. Set your multimeter to read resistance in Kohms, and set the range (if it is not an autoranging meter) to 20K or 200K full scale. The XLR connector should have the pins labeled on its face, but just i... | |
| Relationship between McCormack and CJ? Hello Friends -It is certainly no secret that McCormack Audio was purchased by the Conrad-Johnson Design Group back in 1998. It was then moved back to Virginia, where it shares its headquarters with conrad-johnson. While both companies share resou... | |
| McCormack DNA-2 DLX balanced input impedance Hello AudioGonners! Here is the story...The DNA-2 has both balanced and unbalanced inputs but is not a "true" balanced amplifier, so there is a high-quality summing amplifier following the XLR balanced input. This sums the balanced input signal an... | |
| Rowland 112 vs McCormack .5 Rev A I would like to add a few points: 1) The DNA-0.5 (Rev A or otherwise) delivers about 120 Watts-per-channel into an 8 ohm load. The Rowland 112 is rated at 150W per, so the difference in 8-ohm-power is very small. The real difference is current del... | |

| McCormack Upgrade reviews I would like to add a few comments...1) While I certainly appreciate Bob B's input, he is incorrect about the relationship between my "Revision B" and the earlier "Deluxe" upgrade. In fact, there is no relation whatever. I originally developed the... | |
| Difference bewteen McCormack DNA-2 & DNA-1 ?? I will add just a few comments:1) DNA-1 dimensions are 19W x 7H x 15D. Shipping weight is about 55 pounds.2) DNA-2 shipping weight is about 92 pounds.3) The DNA-2 is laid-out as a dual-mono amp. There is a single toroid transformer, but it has sep... | |
| McCormack DNA1 power ratings I originally rated the DNA-1 at 150W per channel just because I am conservative about this sort of thing. The design of the DNA-1 did not change, but the marketing folks did decide to change the power spec to more accurately reflect the amp's powe... | |
| McCormack ALD-1 question I want to thank you all for your kind words and your support. I don't know that I will be able to post here often, but I'll try to cruise by every now-and-then to see if someone needs factual information about my equipment. Many of the questions h... |
