I have an Eden WT550 and 2x15 cab. I think it's the best of both worlds?
The WT550 is by a long margin the most impressive head I've had the pleasure of using. More power than you'll need, best sounding and most versatile preamp i've used, small, 2ohm capable, and as light as is needed.
The 2x15 is a freakin monster, huge sound (obviously..) but with as much punch and top end clarity as other, smaller cabs i've owned (schroeder, glock, eden 2x10). Easily moved around thanks to built in tilt-back casters. But amazingly light considering what it is! Easy to lift on your own (though it's size makes moving around once you've picked it up tricky..) and a breeze with 2 people.
Also, it fits in my Nissan Micra! Deffinitely the best of both worlds!
