I really don't think you are going to beat the Mesa mk5:25. Don't think it's gonna happen. I have played one on several occasions, and can say that it punches above its weight class.
~15.4lbs
2 channels,
load box/powersoak (20W/5W/1W/off)
headphones out
FX Loop (footswitchable via MIDI)
IR loader (8!!!) with USB input and dedicated XLR Output
MIDI In
onboard reverb, delay, noisegate
Next to the aforementioned Mesa Mark V:25, it's the only other lunchbox amp that I own (the non-SE version though) and is worth something, since it can still sound huge.
