Thank you all very much for your answers!
I suppose this topic needs some attached FAQ with all those tips for the amp.
Does this Elac DBR62 sound good at low volume with Sabaj A30a? I've read somebody complained that they need some medium volume to be OK, and not good at low volume (maybe it was the particular amp's fault). But I like it's design!
Max. 1000-1200$ I suppose
My candidates, that I suppose sound good at low volume (maybe I'm wrong) are:
(but don't know what is the best match for Sabaj A30a, because not sure I can test 'em all with the amp, seems it gonna be a full blind purchase based on recommendations):
Main candidates in perfect low price range:
Acoustic energy AE100-2 (afraid they could be a bit bright and monitor like, but not sure)
Mission LX3 mk2 (a bit cheapy look and afraid it could be too boomy, but someone here at ASR wrote that it sounds even more pleasant than Elac DBR62)
Elac DBR62 (not sure it's good on low volume)
Main candidates in higher price:
Dali Opticon 2 (first version or mk2) (not much info about it, but it seems to be good)
Piega Classic 3.0 (hard to find and not much info about cons., only few very good reviews that is a bit confusing)
Focal Aria 906 (not sure I like design for the price and have read that they need too much time to warm up to sound good)
Martin Logan Foundation B2 Walnut - (absolutely perfect design for my taste, but no any info anywhere about it and I afraid could be not good at low volume because of aluminium woofer and could be bad off axis because of horn tweeter, but it's only my suppose)
Dali Rubicon 2 (in walnut) (I like a lot how it looks and specs., but it's a bit too pricey for me, not sure it really worth the price, but if it's really superb and totally worth it - I will try save up for it)
