McCormacks -- For lovers and investors

@soix - Hopefully the ebay buyer's DNA-0.5 amp will not suffer the same fate as yours - at least not in the near future.  However, your amp is not exactly a boat anchor since even in its current non-operating condition, it can be upgraded by SMc Audio with the result being competitive with many of the better amplifiers available today.  SMc now has new boards they can use to rebuild those older amplifiers, and it would probably make sense to upgrade at the same time.  If you would rather sell it than upgrade, I suggest letting SMc know so they can pass your name along to a potential buyer who needs the chassis/heat sinks for their upgrade project.  There would be no difference in value to that buyer between your amp and a working stock DNA-0.5, which I usually see sell in the $600-$800 range.  Someone may purchase it simply so they don't have to wait for one to come up for sale.  Just last year, I purchased two old DNA-1s that SMc then turned into Ultimate-G monoblocks, and it didn't matter whether the amps I sent to them were in working condition or not.

Hopefully the ebay buyer’s DNA-0.5 amp will not suffer the same fate as yours - at least not in the near future.

@mitch2 — Hate to be a negative Nellie but unfortunately it absolutely will fail. I spoke with SMcAudio about it directly and they said the input boards of that era are physically at the end of their lives and not possible to repair or replace and that the rest of the guts are basically trash. Not what I wanted to hear. They said the only viable option would be to use the carcass for one of their upgrades that replace everything, which is what I plan to do as I really loved my amp before it went kaput and can’t wait to hear how much better the new upgrades will sound. Now just need to save up enough shekels to git’er done.

Incidentally, what do you think are the standout sonic strengths of your SMcAmps vs. stock (if you’ve ever heard that) and what other amps have you compared them to? Also, what level upgrades did you consider and why did you choose the Ultimate-G? Not sure if it was you, but I remember someone saying the new bases are very worthwhile. I’m not familiar with Steve’s latest upgrades so appreciate your thoughts having gone through this. Thanks for any thoughts/advice!

@soix. 
 What about the conrad Johnson made McCormack branded amps?
are these also susceptible to the boards going bad as you previously  mentioned??

Gents,
Steve M told me that they can't source components for aging .05 amps which could be problematic for folks. 

I have moved to tube amps in the past few years and have a DNA .05, upgraded a few years back to their Platinum version (i.e, but for the chassis, every component inside is brand new).   The upgrade cost was $3800.  I am happy to have it in my stash of gear, but if someone is keen to have this outstanding amp, please send me a PM.
