Some places really lag on charging for some reason. I've received things before being charged on a couple of occasions. I was sad when they didn't just forget to charge me.

[quote=mdrew}...I see pictures showing a receiver with mulitple amplifiers. Plus, John reads way too many tech manuals to be this wrong... [/quote]
Mike,
Receivers may not have physically separate amplifiers in the form of their own separate boards. But each channel must have its own amplifier even if all of these amplifiers are concentrated on one board. All of these amplifiers in an integrated receiver do share one power supply however as they do on a power amplifier.
Note that the A1400 has 4 boards...for 8 channels. Each board has two channels on it. Provided that each channel has "enough" physical and electrical isolation, each channel will not be affected by the operation of the other.
I am sure that John did not mean that a receiver has a single amplifier. He was trying to simplify the complexity of the point he was trying to make.

No Mo, that's exactly what the case is: an amplifier has to have both a power supply section and one or more channels of output transistors to measure out the required amount of power to each speaker. These receivers that have been discussed in relation to supposed "biamping" have only one power supply section and therefore only one amplifier, although there are as many as seven channels of output transistors(which have no amplifying ability independent of the power supply).

All integrated receivers and the majority of dedicated power amplifiers have a single power supply section. Some amplifiers have two but that really is a special case of one as you know.
I consider an amplifier to be a circuit which takes a low level signal and converts it to a high level signal. In that regard, integrated receivers have multiple amplifiers.
If there was only a single amplifier, a multiplexer would be required to connect this singe amp to the speakers and you know what kind of a mess that would cause.

Tom, How the heck did you know? That's exactly what I'm enjoying right now. My wife is a master egg salad maker . The cabernet shiraz makes it go down that much better.

Well I got my 3808 from 6ave today. I ordered it on Wednesday last week and got it today, not bad at all! It also survived shipping unharmed, which is also good. Came double boxed with a fair amount of foam 'peanuts'. The box is pretty heavy! My only complaint is that I told DHL yesterday to leave my item at the shipping center and I would pick it up. Came home and found a $1600 box (which i got for $1098) that had been sitting on my porch all afternoon I probably won't get around to plugging anything in until my axiom's arive. Initial impressions based on looks and feel alone are great. Looks like one heck of a receiver. Thanks again mdrew for pointing out the limited time sale! My order from blue jeans cable also came in today. However, yesterday during breakfast I was looking at the perimeter of my living room and realized I had not ordered enough 12 gauge speaker cable So I placed a second order form BJC... should arrive by thursday or Friday. Now if I can only find a way to occupy my time until my axioms arrive. This is going to be the longest two weeks ever!

^^ Read the manual for the receiver. Then, it'll be easier to set everything up, once the speakers arrive. At least you will know the GUI, it's functions, and the capabilities of the receiver itself. Get wiring ready, so it's almost ready, once the speakers arrive. So many things to do...so many...hehe.
