Wow...a real H&K aficionado. I just made the transition from Blackstar...pretty sure the cleans are deeper and more pronounced. Really enjoying it so far.
I've spent a good amount of time on a Blackstar HT100. It's a good sounding amp, through a Mesa 4x12. There's just something about the H&K that does it for me. I'm quite the fan, having the three Meisters, a Triamp MKII, Switchblade head, and Switchblade 50 combo.
