So assuming the mid+high is drawing the max 60W from one channel, and the woofer is also drawing the max 60W from the other channel, isn't there 120W of total music power coming out of the floorstander? 60W of mid+high energy from its dedicated channel, and another 60W of bass energy from the other dedicated channel. No this is not correct. As said before the two sections cannot be added to together as neither section is receiving the perceived 120 watts. If the straps were left in place and the floorstander is driven with only one channel of 60W, assuming a 50/50 split then the woofer gets 30w and the mid+high gets 30w. This is also not true. As the 60 watts cannot be combined the same goes for dividing the 60 watts. The binding strap are an electrical conduit just as speaker wires are. They will transfer the power to both sections the same as when you are bi amping or bi wiring. In any case, what is the benefit of bi-amping? The ability to pla y twice as loud (120w total music power) vs 60W, or playing with less distortion at the same level as each channel is only at half power. There are no benefits to passive bi amping. To achieve the ability to play twice as loud you need to have TEN times the power......600 watts.

'Yo Wid ... have my man Slack check out this article, it should help him understand the theory behind bi-amping a little easier. Bi-AmpingGo ahead, you can use the link Ricky.

I think I'm beginning to get it, sorry for the frustration to you guys..*sheepish grin*. Thanks!
If i have the option now to buy a used Parasound HCA-806 to replace the two rotels, i guess it is not considered much of an upgrade in terms of power.
How about the sound quality, build quality and tonal characteristic of the Parasound compare with the Rotel amp?

Amps are about power slack, not sound quality and tonal characteristics, they amplify. Build quality is another topic, which I can't comment as I don't own either brands.

Yeah, but i'm sure every one has experienced power amps that sound different, for one reason or another..: ))

Those reasons mostly being slight differences in volume setting.

Slack, if an amplifier has a "tonal characteristic" when its controls are set flat, there's something wrong with it. It's either a damaged sample, incompetently designed, or intentionally designed not to be sonically accurate and impress those who might equate different with better. An amplifier isn't a musical instrument and its only function should be to amplify transparently, with audibly flat frequency response and inaudibly low noise and distortion within its designed power limits. Nothing more is possible. One of the great features of today's audio scene is that even modestly priced receivers can accomplish this.
Certainly a contrary view exists, but when put to the(controlled blind listening)test it collapses because of the lack of solid evidence to support it. Both of the units that you mention meet the standard for transparent amplification.
