Dear: Ryllau
That question is the sort of which I would myself ask when we are constantly seeking for the most satisfying audio performance. However, I think, to hang on for life, we should really look for speakers that is more towards the natural ends... I prefer spendor, pro ac and perhaps the liuto (SFBR) clan of speakers. Fancy things like the avantgarde horn will have some downside at somepoint of time because it emphasises only in some strength rather than universality. However, if we are willing to spend for life.. that is another option.. go for kharma or latest B&W as reviewed recently in the TAS.. Happy seeking..Cheers and Merry Christmas
