proac tablette - signatures / rainmakers, et al


Does anyone know how these compare? I listen mostly to rock, blues, soft stuff like Norah Jones, nothing hard.
I'm thinking of moving up and these makers have been suggested, in part because of fine detail. A sub would be used. Thanks.

Sufentanil, have you listened to anything from Amphion? If so how do you feel they would compare to what you've mentioned? I continue to be really happy with my Argons but haven't been able to compare to many other high end monitors so always interested to get impressions from others.

I've heard the vr-1 but it was long enough ago I don't remember well enough to say. I've heard a few from the jmlabs line but not the Electra, and while I found them initially pleasing ultimately there was something artificial about them to me.
I haven't heard Amphion though I did read a fine review in Hi Fi. Part of the need for research is that I have no audio stores that carry high end equipment near by. All of your input is very helpful, narrowing the starting point. I hadn't consider Von S v1 or Amphion. Do dealers give try outs? Buying unheard is risky, $$. Thanks to all.
