McCormack DNA 125

@bigkidz  Following this thread because I have a DNA-1 amp and thinking of doing the SMC update.  Is this something you’ve done or are familiar with?  I’m also in Jersey.  Thanks.

My DNA-1 is my go to amp and still sounds great.  That said, it’s older than my adult sons so probably time to swap out caps and new board. Toying with the idea of going with something new but good to hear others have had good experience with SMC.

@nymarty - Very familiar with.  Swap out power supply capacitors, upgrade resistors to higher values is also a good idea.  You can also try V-Caps and I can let you hear amps that have them.   

@bigkidz Thanks.  Is this something that you do for people -- recapping and upgrading amps?   If yes, are you associated with SMC in any way?  Sorry if I'm reading this wrong and you just have experience getting amps serviced/upgraded at SMC.  It looked like in your first post that you were offering help to highend62, the original poster. 

@nymarty - I am not affiliated with smc in any way. My partner and I have been repairing upgrading rebuilding audio equipment for over 30 years. We have our own products. Google vujadeaudio  peter

Sorry, can't comment on the DNA-125 but I owned both the DNA-1 and DNA 0.5 about ten years ago and for some dumb reason sold them.  I few years ago I got lucky and picked up a DNA-1 on eBay. I'll not sell this one.

I have used the DNA-1 on Raidhos and it is very good, but possibly a better match for a slightly cooler speaker. The sound was good but I use a W4S STI-1000 instead as the W4S provides better clarity and detail and has a great hold on the bass.    I really like the DNA-1.0 on my Martin Logan SL3 electrostats.

I cannot imagine you'd be disappointed with the amp. Good luck.
