McCormack DNA 125

The DNA-125 is excellent — it’s got the detail and bass you’d expect from a solid state amp, but it has tonal heft as well so never sounds thin or sterile.  Also excellent 3D imaging/soundstage.  And you can always send it back to SMc Audio for upgrades and turn it into something pretty special.  I’ve got my DNA-0.5 RevA there now getting full upgrades.  I have no idea how it would compare sonically to your ST2140.

That is so weird that you posted your previous amp , as I went from a 2140 which is a great amp to the DNA 125 which is much better in my opinion.    The 2140 was a back up amp.   I decided to sell my tube amp at the time and the 2140 was doing fill in duty.  The 125 is technically a Steve McCormack design , sort of but it was built when CJ acquired McCormack.  It was built in the CJ factory.  I actually regret selling that amp, it was damn good.  I would leave it alone, the money spent to buy that and mod it is $$$   others may disagree but for me I would leave it stock.  Good amp

@oddiofyl I agree, upgrades are pricey but I liked the sound so much in stock form I decided to take the hit and make it my forever amp.  Steve told me a while back the 125 is similar to a 0.5 RevB, I think.
