The latest Ashdown ABM 600 is a significant move forward when compared to the previous models. I'd definitely try a MK IV first before making a decision.
New band to me... Sounds Like Winter, from Oz.
I'm on my way through the latest album, it's cool.

We do a cover of For Her Light as a warm up at rehearsal... I can't take them seriously though. Proper comedy goth voice, they make me laugh whenever I hear them.
I had one, I didn't sound like a Trace Elliot and wasn't as loud as the numbers suggest but was perfect to use with a quality pre amp and was well built.
The nearest that I have tried was a GK Fusion 550. The big one not the Class D.
It reminded me of a Trace Elliot as soon as I started playing through it, I should really buy one instead of trying every other amp on the planet. Lol.
