In the past I have owned a pair of Vandersteen 2 C's I paired with an Aaragon 4004 and Audible Illusions 2C pre. I agree with Bigtee that the ss amp and tube pre combo give you most of the tube benefits without the tweaking and maintainence a tube amp demands.
I have not found a speaker at the 2CE Sig's price point that offers such even and musical sound without some glaring fault that, for me, leads to speaker fatigue i.e. lack of bottom end, glaring or steely highs, etc. For this reason the 2CE Sigs will probably be my next system upgrade from my current vintage 15 amp Rogers LS3/5 a's. I would be most interested, Ataqi, in how you find the match with the Belles 250i and the rest of the amps on your list. On paper (power, specs, tube pre, etc.) it seems as if it would be a wonderful match if the amp is as musical as touted.
I understand that Richard Vandersteen voices his speakers through ARC gear so I have been hoping to hear the 2CE Sigs through some of this gear as well, perhaps a 100.2 amp and tube linestage or the new 150.2 integrated.
