Devore gibbon nines look for best amplification

thanks my friend im enjoy my devore nines too.
but i was sell my cary sli80 integreted amp beacause in the low frequence it was little spread ,i mean the bass
and now i know its because the aqustic in my living room is terrible reinforced concrete.
now i replace my cary sli80 with nuforce 9v2 monoblocks (digital amp),because i wanted more control on my speakers and now i use my cd has preamo lol, now i must search for agood comb with my nuforce. or maybe to sell them and buy power tubes amp .

but i like to know for sure what is more good comb with my nuforce the EAR834L OR CONRAD JOHNSON PV12 OR MANLEY OR ROGUE ?
