Getting a new head - need advice

The reason I was leaning towards an 800 rather than any other Marshall is mainly because of the latest Hate Eternal, according to Rutan it's just a plain un-modded 800.

Last hate eternal has jcm800 indeed, but he used a powerball as well ... at least that's what he said in this interview

The tone is great ;) thick and warm
 
Just wanted to bump this as I (hopefully) have found a buyer for my current amp.

I was just wondering how JCM800's perform at low (bedroom) volumes?
Because that's what whatever I get is going to be used at 99% of the time.
 
That's what I thought.
I'm definitely not investing in any sort of amp sim, dat shit shtanks.

By "bedroom volume" I mean up to about 1 on the post gain of a 5150 combo.
So it's not tube crippling, but it's low enough that I'd need to consider what's going to perform optimally at that volume.
