My speakers are Martin logan aerius i. I had a bryton 3bst, I sold it after lissening to the bat vk200. I also auditioned the plinius, ar, mccormack, meridan, audiomat, signature and many others. I completely crushed all of the above in every area. And had excellent surenergy with the bat 3i pre. Never had the opportunity to listen to M Lev gear, or pass. I now own a vk200, bass response is excellent and so are mids and highs.
Good luck
