Some clarification:
I know both Mark O'Brien and Victor khomenko personally, and I am not comparing their personality or moral character, but as engineers who are measured by their success with their product. I am in a position to make a comment, especially one which relates to the fruits of their labors...namely, these amps. Next, I have owned two pair of Rogue M120s, the VK 500, VK 60, Used in the same system, with a Wadia front end, Aerial, Martin Logan and Magnapan speakers and all Nordost SPM and Quattro fil...I can tell you the differences. Yes, the BAT is more money, but you get what you pay for and in the case of BAT, that means excellent customer support, new tubes overnight, a great warranty and a low failure rate throughout the life of the product and the product line. When was the last time you checked with Madrigal Labs for a Levinson upgrade? How about Krell? Jeff Rowland?...Think about it: a ten year old piece of gear which you have derived much pleasure from, can be upgraded, not become obsolete, outdated, discontinued... The original Wadia D/A processor can still be brought up to current spec. Yes there is a cost, yes, it's expensive, but THIS is customer loyalty AND manufacturer loyalty if a piece of gear is still owned ten years from now, and the upgrades are still offered and the listener is still satisfied. Apples to apples, the VK 60 Monoblocks absolutely kill the M120's in every area of performance. Yes, the cost difference is great but only you, the listener, can decide if the sonic rewards merit the additional expense. Bottom line: whatever you do, audition BAT in addition to your other choices...you will like what you hear!
