Deleterious effects of bridging ??

I am considering the following two options for purchase, both being approximately equal in price.

(1) NAD C370 integrated and C270 power amp in bridged mode (300 wpc @ 8 ohms, 70 amps peak)

(2) Parasound PLD1100 pre and HCA1500A amp (205 wpc @ 8 ohms, 60 amps peak)

I cannot biamp with the NAD amps because my Magnepan SMGa's are not biampable nor biwireable. Thus, the NAD's must be run bridged.

According to the salesman, bridging stereo amps has undesirable consequences by "trashing the damping factor of the amplifier." Thus, he suggests going with the Parasound separates.

Given that I believe in so little that I hear in regard to either audio or politics, my question is simply is there any foundation to the salesman's claim, or is he just talking out of his ass, so to speak?

The remainder of my equipment is as follows:

Adcom GDA 600 DAC
Monarchy Audio DIP Super Drive
Pioneer Elite PD-F27 CD Changer
Apogee Wyde Eye 75 ohm & 110 Ohm digital cables
MIT T2 interconnects and speaker wire
Monster Power HTS2500 Power Center

Any feedback that you can offer would be most graciously appreciated.

one ting i've always wondered about bridging & current. my electrocompaniet aw60ftt's put out >60amps current & are rated at 60wpc. bridged, they are rated at 220w - not quite following the pure model of quadrupling to 240w, but close. anyway, is it still putting out >60amps current, or does its actual current output *drop*? in stereo, electro sez it'll remain stable w/speaker loads down to 0.5 ohms. does it still remain stable at these loads when bridged, or is its stability reduced to, say, 1.0 ohms? or, are these characteristics amp-dependent?
