I haven't owned a Blackmore..yet, but I did own a Savage 120 and a D120 at the same time, and while the D120 was awesome sounding, the Savage was a little tighter and much brighter than the D120, and the Savage 120 that I had made the D120 sitting next to it sound weak in comparison. So if the Savage 120 and Blackmore are anything alike, as I have heard from many folks, then teh D120 would be pretty good, but it won't be as tight or bright as the Blackmore.
I feel I should add as well, after owning the SE with EL34s and 2 different Savage 120s, the Savage is still my fav ENGL amp to this point. I just wish they made a Savage 120 with 4 power tubes instead of 2....the added punch and oomph from 4 6550s would be mind boggling, to say the least.
I'm excited to hear a Blackmore as well after eharing Mega talk about them as he does, since we seem to probably be into the same sorta stuff.
