I have the Violectric V281, and also I have the Liquid Platinum, and I love them both very dearly for what they each bring to the table. Now, from the viewpoint of my experience, and to my mind and ears, your evaluation is so wrong on so many levels that I wouldn't know where to start listing the errors, if I wanted to, which I do not at this moment. Ideally, I would say you should begin with a review of whatever other components you had in the chain when you auditioned the Violectric amp (was it the V280? I do not know how to interpret your expression "the Violectric stuff"), because it seems to me as if you never actually got to hear it, not even at a fraction of its level of optimal performance (by which I mean that the surrounding components must have compromised the sound to the point where you couldn't hear half of what the amp could do when properly fed and accessorized). It is a pity you sold it. That is all I can say.
Suffice it to say that I do not recognize anything like the sound signature of either v280 or v281 in your description, and think you should not be surprised if you get a lot of bewildered responses to your statement. With all that said, your mileage may vary, since your opinion reflects what you heard in your system, with your ears. I always respect that as a matter of principle
P.S : I just noticed you were referring to the V200 and V280, but "bass heavy,"? I wouldn't argue with "slightly warmer side of neutral," but I have never found my V281 to be any more "bass heavy" than my Liquid Platinum, with allowance made for variations in sound signatures arising from tube-rolling, of course. The V281 does bass very well, but I. wouldn't call it a bass head amp, if there is any such thing. Again, your headphones, your ears, and other components in the chain are always determinant, so of course, YMMV
