thegame:
If the clone got 95 % there WITH easily available new production tubes AND offered increased reliability (from a maintenance standpoint AND the ability to retain it's tone/feel over several hours of playing time, which is something at least some old Marshalls have a problem doing), then I'd gladly take the clone.
You both make some very good valid points and I agree with all of them. I would also add the not every vintage Marshall has the "IT" factor either. I've played many "MEH" Marshalls in my day and even some dogs. So the vintage route is not always a guarantee of amp tone nirvana.
You see it alot with comments in video clips.... "My 100 watt Marshall never sounded like that"...............What are your settings??????.
I think it comes down to some amps have it and some don't and sometimes it's a function of the amp gods smiling when it was put together.....as frustrating as that statement is...........
