Hello.
First of all, clean all pins and contacts very thorough with for example isopropyl alcohol or something comparable. Maybe they're oxidated or just dirty.
To sort out if there's a general problem with one of the 4 tubes, you should switch sides one after another. So you could start with the driver tubes and switch left and right channel one, then do the same with the power tubes.
If the problem "moves" you're smarter and got the "bad" tube could be identified.
I'm not that sure but I don't think just the lack of burn in time is responsible for your misery. Sound does improve - normally volumes you be nearly the same even with no burn in at all.
Did the problem turn up since you changed tubes or before?

Stupid question: Did you set the jumper right on the "EF92-positiion? The M8100 is a EF95 (jumper position OFF). Did you change the jumper setting? I hope so... If not: this could be your problem!!
If the EF92 or the M8100 is the better tube can't be finally decided. It's all about your personal preferences and up to you to decide which you like best. Both are very good tubes overall.
Wooohoo!!
Crash course: Jumpers are little (in this case) black "bridges" which are put on pins. looks like this http://www.paules-pc-forum.de/infothek/artikel/hardware/bios/CMOS_Clear/CLEAR_CMOS.jpg
Just black in your case.
There are two positions: the EF95 (standard / OFF) and the EF 92/91 (called EF92 on the pcb). You absolutely have to change the correct config to use these different types of tubes!
You get to them by looking at your amp from underneath. There are holes through which you can reach them and put on the correcht pins. Use pincers to grab the jumper.
And: read the manual!
