I was on the same quest for the last few months.
The LG's don't sound anything like Ashdowns other amps, they're not meant to, no tube preamps.
Same thing with the LMK II's and even the new III Tube, its a warm tube, not a grind tube. Shuttles also have a preamp valve...but again, it's warmth...not grind.
My Ashdown EVO II is warmth and grind all built into one....beautiful amp, and I found the Orange to be the closest to it toneally than all the others. No it doesn't fit into a gig bag pocket, but it is tiny and light, with a bag to carry it in.
The Ashdown has more scope with it's EQ, but I actually think the Orange is louder....it's neither here or there really, but just saying. I still use both amps, they have applications that each of them suit. A lot of the time I just take both...good to have spares
