I own ML Aerius I and just upgrade from my bryston 3bst to a BAT VK200. Best move I've ever made and I will be keeping the BAT amp for many years to come. The 3bst is rated at 125 watts, and the vk200 at 100 watts. While the 3bst is nice, the vk200 blows it away. Very controlled, tight base. Mids are alive and highs are sweet. Plenty of power; pushed the amp and would not clip. I've auditioned so many amps (classe,plinius,audiomat,AR,sunfire,meridian, and a few others) the vk200 worked for me. Clean, clear, definition and detail. Seems to play all music very well; rock, rega, blues, jazz, HT and even the wifes rap/dance crap. Check it out, worth a listen. I paid $1800 for a demo at the dealer. Good luck.
