What's better? 1 amp of 250wpc OR 2 amps of 135wpc each one?

Hi guys! my question is because I want to upgrade the amplication section of my system. I want to continue using the PREAMP section of my integrated amp (Musical Fidelity A300), but don't know what would be better, if using a 250 watts per channel amplifier (for example the Bryston 4ST) or if using a Musical Fidelity A3CR that is 120 watts to PASSIVE BI-AMP with the amp section of the integrated, so that's my confusion, What's better? One amplifier of 250wpc OR two amplifiers in passive biamping that together give 250 wpc? The A300 is 150 wpc and the A3CR is 120 wpc. Both are gain matched. I'm happy with the loudness I get with the A300, so I do not need my system to play louder, hence I also wonder if the AMPERES I have with both MF amps will cause a better improvement than the amperes I have with the Bryston 4st, or definitely more watts are better than more amperes?. Thanks for your recommendations. jorge

Thanks all for your responses.
Jvr and Sean, I want to upgrade the amplification section due to I feel that my speakers (Magnepan 1.6qr, which are very inefficient)are not being driven with "ease", even I think the a300 is loud enough, the sound from the speakers is thin, so I thoght that the cause of this could be that the current was insufficient. I know that I would have more improvements with active biamping but I don't know if I can do it with an integrated amplifier. If this helps, my little system consists of: MF a300, MF A3CD, Analysis Plus Oval 12 spk cables (biwire set), Analysis Plus Oval copper interconnects, monster HTS2000. Thanks again for your responses...jorge.

Sean, your comments does not bother me, in fact, I think you probably are right. I was already thinking of adding a powered subwoofer (for instance a rel strata III). Yes, I think the upper bass is weak currently, but I do not understand how is that by adding a sub it will "remove bass duties from the Maggies and I will free up more power for the upper bass, mids and highs"?. My understanding is that the subwoofer simply will "see" frequencies (low) that the Maggies do not "see", so the speakers will do the same (will have the same current or power from the amp) with or without the subwoofer (please correct me if I'm wrong), so I do not understand how is that by adding the sub it will ease some of the strain from the amp. Could you please explain me why. Obviously I'm not an expert on this. Thanks for the input ..jorge.
