I would have to argue with above comments. I have owned my VK-50SE along with the Electrocompaniet mk2, BAT VK-60 monoblock and a pair of Verity Audio Parsifal Encore speakers for just over a year. I auditioned more then a couple of pre amps before I purchased my VK-50. Soundstage is unreal--very deep and very smooth. When I listen to music, some of the instruments sound like they are comming from the back of the room and others sound close, just like they would in a live performance--and that is what we are searching for. Build quilty of all BAT products is second to none and there customer service is unmatched! In my opinion, you should audition both if you can and let your ears and your heart decide for you. All I can tell you is the VK-50SE really draws you into the music, you feel the emotion come through true and clear. There are alot of great preamps out there to choose from and you have picked two winners---good luck!
