I must say that these attacks on BAT are a bit much. One buys an amp from a manufacturer that one thinks sounds great(why else would one buy it?), and then the manufacturer sees fit to upgrade. So what? That manufacturer isn't forcing you to pay for that upgrade. Those who have a gripe here, are those who feel somehow left out or cheated if they don't have the latest and the greatest. I am now auditioning a pair of early production VK60s and while I don't think them perfect, I do think they are excellent sounding amps by any measure. As far as the BAT v Rogue comparison is concerned. I auditioned a pair of Rogue 120s in my system last year and they were pretty good, but in my opinion not in the same league as the BATs. In fairness, the Rogues are alot less money though. It is entirely possible however that someone else, with a different system may prefer the Rogues. Different strokes. Oh, I also own a BAT D5, have for two years now, so I'm quite familiar with their customer service which I've found to be quite good.
