For future reference to others who start on the FRFR quest
I've ruled out the Yamaha DX12 and the QSC K12.2 because they don't have a wooden casing which I personally prefer the tone of when gigging/practicing.
I've learned that the early EVs had a problem at low volumes with the base notes distorting as they cut off, but apparently that was a long time ago and it's all fixed...the Xitones are VERY decent defo worth trying but it's generally considered that they are slightly voiced to sound a bit more like a cab (much like the Friedman ASM-12s) and a lot of people who've had the RCF NX12-SMAs have upgraded to Atomic CLRs because it was worth it........funny thing is the RCFs cost like £350 MORE than the Atomics do nowdays.
It is for that reason that I'm going to try the Atomic CLRs first....then the RCFs (because a few people say they have a better tone) and probably the Xitones, but I will give the EVs a miss!
