Hi k.s.- The bass in the Emmline was great, no problems there. Yeah, it's basically with the V2 that I had a problem. Seems like the V2 was able to hit some low notes but didn't have enough mid and upper bass. Tuberoller explained it well in his reviews and I guess I concur with his assessment. It's not just the lack of oomph necessarily, it's the detail within the bass and more importantly a lack of mid and upper bass which often translated into a lack of fullness in instruments and vocals. The other amp I meant was the MG Head. Now, it's bass is actually quite good, definitely full, but it's not the champ at deep bass or punch. Actually that's a tough one, the bass in the MG Head is very satisfying with the HD600's, enough that it is not distracting at all, but under a microscope it isn't thrilling.
I am not a bass freak but the bass needs to be there, for me ideally it needs to be full and present, articulate, punchy and deep. You usually can't get all that though. So I tend to trade articulation or maybe depth for fullness, myself. Others prefer it the other way around. To me I'd rather have the body of notes be there even if their front ends are rounded off, rather than just hearing the definition of the front end and then the back end of the notes are gone.
Didn't you have or just sell a Mikhail amp? Didn't like it?
