McCormack Amp Upgrades

I had a pair of DNA-1 monoblocks driving Vandersteen 3A Sigs, gave those up for a pair of DNA-1 Dlx Golds (non momoblocked) that are vertically driving the Vandy's now and they are so much better than the monoblocks, I put the monoblocks back in a couple of weeks back and the bass was so over driven they didn't last the weekend (too much power). I also have a McCormack Micro Line Drive and a Micro Phono Drive that I had upgraded to Gold and they are not the same peaces of equipment they were before the upgrade, I know because I have the stock versions of both in my computer room. A great example of the improvements that I can give is on Dave Brubecks "Time Out", while Dave is playing the piano, as the hammer is striking the strings, with the stock equipment it sounds as if there is a layers of felt on the hammers and with each upgrade a layer of that felt is removed, making the notes sound more real and less like a reproduction. The funny part is without hearing this I didn't realize I was missing it. When doing a comparison I could not believe the difference. I tried the MLD in place of my TLC-1 Dlx and everything just became that much clearer, greater transparency, with more depth along with quieter, blacker back grounds, wow I was in heaven. The improvement were so great I've scheduled my TLC for the Full Monty with the Carbon wiring. Yes the bad part is you can only get back about half of your investment on the upgrades but if you have plans to sell your equipment down the road then you would be better off waiting till a modified unit comes up online and do a comparison then. By the way many Agoner's here recommend a tube preamp with the McCormack's and with the power demands that your Von Schweikert's have you just might wind up with an outstanding combination.

Thank you, I've learned something new today, I did not know that about the hammers on a piano, I guess I and will have to go back and see what it is that my system is presenting to me then. I'm new to the high end of audio and still learning the terminology, so this is whats meant by Tonality? I can see your point about the upgrades possibly causing listener fatigue especially if the speakers your hooking them to are very revealing to start with. A very revealing amplifier with a very revealing speaker might be very very revealing. I guess this is what they call system synergy that comes with system matching? Still so much to learn. But like I said the upgrades make "the notes sound more real and less like a reproduction" in my system. So with that said.

If you live within about 3 hours of Philadelphia and are willing, I would be more than willing to bring my pair of McCormack Dlx Golds to you place so that you can experience the upgrades and determine for yourself if they will be a good match in your system. And maybe learn something more about this system matching stuff for myself.

I agree with Audphile1 the McCormack's need to be left on to bring out their very best.

Audphile1 my Apologies for coming off so harsh on the last posts, didn't realize how bad it sounded till I went back and read them again. I also sat down to listen and see what it was I was hearing with these upgrades and could see where these upgrades might be to much in some systems. With my Vandy's the improvement's are in the subtle details as well as the sound stage size. I probably wouldn't run these with the NHT's I had before.

Tube540 like you I'm wondering where to spend my money on improvements. Was considering having both the DNA-1's upgraded to Platinum but with the new price increase I'm thinking just one and then upgrade to the Quatro's. Anyway keep us posted on what you find out.
