Genesis! The actual systems are 201 and 350 (and the 1.1 for very few). There is absolutely nothing which can be compared with these speakers in musical sound! They run very good/best whith Classé Audio amps, specially the 401. Often it is said they run good with tube amps, but there are limitations in loud passages with tube amps. Also the Classés give more vividness than tubes. (The Classés run very good also with other speakers)
If you live in Europe, there will be a new company for this kind of speakers next year. Prices will be very interesting.

Also extremly good are the Martin Logan Statement 2, but they are not suitable for most people because of costings and space. The smaller Martin Logans do not have this quality. That does mean that the smaller Genesis models are much nearer to the big 1.1 than the smaller MLs are near to the Statement 2. So if you consider of a very big system both ML and Genesis are your choice, if you want a smaller system take a Genesis 201 or 350 (the smaller genesis models do not have this sound quality).
ML Statement 2 and Genesis 1.1 are by far the best actual speakers in the world!
