I heard Adam A5x compared to Genelec 8050A at a local mini-meet. Now that i actually heard em, they are decant speakers, but Genelecs are in a totally different league when it comes to authentic sound reproduction. I was slightly disappointed by the Adams, in terms of over all resolution. Where you get amazing realism with Genelecs from the lows to highs, the Adams seem to have great resolution only in some narrow area 3k-4k maybe and some place higher up (some characteristic of the ribbon tweeter?). So you are missing out on holographic imaging, realism and depth of instruments and sounds (as if instruments are 2d instead of real 3d physical objects).
On the plus side. (Especially considering that the A5x are midrange, lower price monitors.)
* Adams can do vocals. Not as physical or nuanced as Genelecs, but still, very much enjoyable. One place where the system managed to disappear.
* Highs were decant, did not disturb in anyway, had good bite in certain areas. High hats were well resolved (not as full sounding as the other system).
* Great build quality. Was really impressed actually.
DACs used: Soekris DAC, Yggdrasil
Music: Puscifer, Massive Attack, Pink Floyd, Ladyhawke, Archive, Tool, Hans Zimmer, Arvo Pärt.
As it has been said before, well done R2R with great speakers is something to be experienced.
