I do not doubt having the full SMc mod performed on your McCormack DNA 500 amp would likely improve its performance and that key vulnerable internal parts could be replaced at the same time. But it is expensive and while the amp design may still be very good it is also now about 15 years old.
I've never tried the DNA 500 in my system, but I am aware of this amp's excellent reputation of being powerful and stable enough to drive virtually any speakers while also possessing a very detailed, refined and musical mid-range and treble. A revolutionary design/amp that probably will continue to sound very good until it is unable to continue due to some unexpected cause.
The main reason I thought of the D-Sonic M3-1500 class D monos as a good solution for your situation is because I think their performance and strengths are very similar to the DNA 500's performance and strengths: extremely powerful, very high damping factors for solid bass control, high reserves of power for live-like dynamics along with a very detailed, refined mid-range and treble response that is never excessively bright or brittle.
However, the D-Sonic monos are based on very recent advances within a newer technology, class D amplification, which may scare off some overly risk averse or unadventurous individuals. I just think you'll be pleasantly surprised how reasonably priced, reasonably sized, electrically efficient, cool running and great sounding these mono-blocks are.
I definitely would urge you to give them a 30-day audition in your system before spending considerably more on any alternate option.
Best wishes,
Tim
