McCormack DNA-1 upgrades by McCormack of Virginia

Luigi - Thanks for the input. The Chario Academy 1's are 8 Ohm, but are rated at 84 dB by Chario, and even higher from the bench readings by Stereophile (John Atkinson said "I found the Chario Academy One to be a little more sensitive than specified, at an estimated 85.5dB/2.83V/m (B-weighted). Its impedance, which remains above 10 ohms over the entire band except for regions in the lower midrange and bass (fig.1), suggests that it is a very easy load for an amplifier to drive.") So they are not as inefficient as you might think. In regards to buying new speakers, unless I can find a pair of Usher BE-718's or Odyssey Lorelei's for a really good deal I don't plan on moving the Chario's out of my system anytime soon. IMHO these particular Chario's are a seriously underappreciated speaker - beautifully made and very good sounding. I assume you are recommending against upgrading a DNA-1 myself as the resell value isn't recognized and a pre-mod'd used amp is more economical way to go? I am actually considering a used pair of DNA-1 DLX mono-blocks, already mod'd by SMc (although this is on a hold for personal medical reasons, hopefully for the short-term, but keep your fingers crossed). I know these might be overkill for the moment, but should support whatever speakers I throw at them in the future. How do you like your DNA-0.5 rev B?

Mig007 - How do you like your DNA-1 DLX monoblocks? Anything you might compare them to?

Tpsonic - No I don't need the power, but I do need (want?) the balanced connections that come with the monoblock conversion and am a firm believer in option theory, so the DNA-1 DLX mono's will give me extra flexibility for next steps in the future, whatever those might be.

Thanks all for the input!

Luigi - I love my Chario’s, my sub and my TADAC DAC, the Rega as a transport is fine, and while the Rotel 1080 does a good job, I feel that the amp is is the weakest link in the system. The Chario’s are great monitors, but they are not “mini” at all (the are 14"x8"x13" and weigh 20lbs each). They are constructed and finished beautifully, like or better than a good pair of Sonus Fabers of comperable size. They go low in bass for a monitor, but I also have a True Jr. sub that integrates really well with the Charios. In fact I had a professional system tweaker (works for a local high-end shop) say that he was amazed at how well they worked together seamlessly. I used to have a much larger and less controlled sub in my system and the Sunfire is so much better and more musical. The Charios mid’s are definitely their best feature, but the high end is also very good and clear and as stated before the low end is also good, although the sub integration makes the whole system rather moving. I also use steel shot filled stands with the Charios and that also made the low end more powerful. Overall each upgrade I have made so far has been fully revealed by the Charios, they’ve kept up as far as I can tell. So they aren’t the rate limiting step (yet). By the way the greatest system adjustment advice/tweak I ever received regarded room dynamics. So I now have heavy curtains on the front of my room and small hangings in corners in the rear of the room. This really opened things up. Thanks for the input!
