Don’t buy used McCormack DNA 1990s amps

@nymarty I would direct the funds towards a purchase of a new amp and noy have the old DNA modded. 
 

@soix looks like you’ve taken on a function of being a proxy for SMc Audio to deliver a message of vested interest. No one can possibly predict when the amplifier is going to fail and I don’t recall reading much about these amps becoming boat anchors all of a sudden. 

I’ve owned DNA-0.5, DNA-125 (a good step up over the original 0.5) and the DNA-225 (amazing amplifier, one of my favorites in its stock form even to this day) that I decided to send in for a Gold revision which was a big mistake. The sonic signature changes that occurred with the revision made the amplifier pretty much go from a jaw dropping performance to being unlistenable in my system. And yes I gave it all the break in it needed. This was back in 2006 and around the time I sold that amp the revised McCormack amps would pop up on the market quiet frequently. I also saw “my” DNA-225 come up on audiogon classifieds at least 3 times (could be more but I as well as my audio buddies just stopped paying attention to McCormack amps). 

I believe you guys are making assumptions based on facts not in evidence and unfairly casting SMc Audio in a negative light.
 

@mitch2 

I respectfully disagree. I think Steve is a brilliant designer and I stated my admiration for his amplifiers (sans the modded 225).

However, the manner in which the information here and in another post was delivered and broadcasted by @soix who apparently had more than one conversation with Steve/SMc Audio and in one way or another was given explicit or implicit consent to go on with it, led me to think there’s vested interested involved. I am not accusing anyone of trying to run a business and make a living. But I do have a problem with the nature of OP’s two threads (one targeting specific classified was already removed).

@mitch2 that’s my point exactly. This thread is a gross exaggeration of an issue that may or may not happen. Contrary to the possible intent, it does no one any favors.

@soix Didn’t imply that you started the thread to profit. If you read my response and interpreted it as such, you misunderstood my post. 

@davidbeagrace I recently tried a Simaudio Moon 330a. Thinking it will be a very nice match with your harbeths. Used can be found around $2500. Not discouraging you with McCormack. Just another option that may work just as good or better.
