At least I had a chance to hear it before I die.
NAD: Mesa Boogie Mark VII head. WOW

All thanks to a secondary Covid infection and loss of hearing. I will be out for a while and will not do much for a while. Bummer.
When it comes to the Marks, they eventually start to sound the same. Despite the hearing loss, I did like what I was hearing. Just one thing that bothered me was the low frequency hum I could not get away from. Not at all quiet with the noise floor. However, once you started to play that hum was no more of a concern and would not seem to be much of an issue until you went back to silence (no playing). Amp makes hum without anything plugged into the front end. Have not tried a different location to check noise. The amp is already in the quietest room of the entire house. Also, on a Furman power conditioner. Not a regulator though.
I did remove the front face plate and swapped out the preamp tubes with different types. Some old 1990 Mesa Chinese tubes which usually run very quiet. Then a Full set of JJ E83CC (frame grid). Did not make any difference. The hum was always there and did not seem to be tube dependent. Have not tried any different power tubes yet. Will do that next once my hearing comes back (assuming it will like it did the last time). Compared to the JP2C or the Mark VII, those amps are silent sisters to the reissue IIC+ They barely make much noise unless you push the gain much higher than needed. Still the noise floor is far less than that of the reissue IIC+. I can deal with it. It is not like the EVH 5150 IIIs EL34 100W head, that amp is all noise floor. I do have a Fortin Zuul I could use if needed. The hum us not all that bad though, just present enough to be annoying at startup.
I could not tell if I liked the EVM12L with the Reissue or not. My hearing loss sort of hit me rather sudden so I had to give up on it.
