I use to own the old QLN Signature model, sold it for a small price to my brother, he still has them and they still sound very nice, but the new models are said to be in a different class, I was very close to buying a pair, but had always wanted to hear the BBC sound, so after a long thinking process I decided to buy the 5/9.
If I had place for one more system I would seriously consider a QLN model.
