"...."At the SAME volume, will a higher powered amp improve the sound quality?"
Always nice to have extra power (headroom) on tap to handle the dynamics and the INT-250 @ 250wpc would certainly do the job, as Pass indicated. The INT-25 @ 25wpc, however, is Class A vs INT-250's Class A/B, and the sound quality at moderate power levels may be better on the smaller amp. The only way to find out is to A/B the two in your system.
