I went to another show with a friend who was a big Linn/Naim devotee and spent many thousands on their gear. He was keen to hear the SBL's. His only comment after listening to them was "oh dear". And this was from a bloke who was using Linn Saras of all things .
Mind you, I wasn't too sure about his ears. He went on to pair a set of the very first Acoustic Energy AE1's with two Naim 135's and matching pre-amp. You could strip the wallpaper off with the resuliting sound .
