Catman may have an axe to grind, but he should get the facts correct before launching into his "diatribe". At any rate, in his "rant" about BAT let me say that he is first, not comparing apples to apples. A VK 60 or VK 60 SE is not the same as a pair of Rogue 120's...heck, they're not the same amp in the BAT product line. Check out the specs and get back to us. Second, the costs quoted are not accurate numbers, and bringing a rev.C board up to the latest, as we all know, can be costly. Third, and most importantly, the VK 60 SE is a completely different amp, more akin to the new VK 75, which uses the 6H30 SuperTube also...not exactly a "board upgrade". The VK 60 SE, which is still available as a special order product, is a more costly product, virtually rebuilding the entire amp in the process...therefore, the comments about upgrading to stay current are not accurate, as you can upgrade, or you may move up to a SE edition of the amp. The VK 60 was introduced at the 1995 CES, it had a production run of 5+ years, before being upgraded so much that it evolved into a new amp altogether, hence, the new VK 75. Rev. circuit board changes are not the issue...it's the ability (or lack of) to move from a standard issue VK 60 to the SE edition which has Catman miffed. Do your homework and audition both amps if possible, but let me tell you, the old adage holds true here: "God is in the details." Check out the feedback on various websites, industry reviews, continuous class A recommendations, white papers on both amps and listen for yourself...Mark O'brian is no Victor Khomenko...and don't get me started on the virtues of the VK 60M, 120 watt monoblock amps that smoke the Rogue 120's...(there's another version of the VK 60 Catman forgot to mention.)
