I would like to hear some comments on the upgrades for the McCormack DNA .5 amps,especially the revision A mod.

Do it. I used to own one and I had Steve upgrade it to a Rev. A, and I loved it. I got the tube fever, and not being able to afford both, I sold my .05. It was probably a mistake--I miss it! My humble opinion.

I understand the Rev A upgrade is in a whole nother league from just the regular amps and preamps.

I do think that the sound improved especially with deep well controlled bass. My experience was very positive. Steve was prompt and reliable.
