Adding an Accuphase A-46

It will make a difference because it will handle transients better.

Thanks guys. I guess other than considerations relating to added power, my concern is how good the preamp section of the E-560 might be. Dave 72 - thanks for your input on this point.

So the E-560 is going to be run as a preamp only? What about the amp section, is it going to be churning away in class A at idle the whole time?(Class A amps dissipate max heat at idle as there is no load to sink energy into) this seems like a waste both of a good amp and electricity. Seems to me, you would be better served by just going the amp/pre route and selling the E-560.

Good point Spinaker01, I was under the impression that the power amp section of the E-560 shuts down when used as a preamplifier. I'll have to check this with the dealer, as well as various prices of preamps if I decide to upgrade. Thanks.

Actually, I just checked - the E-560's brochure states that an Ext Pre button allows separation of the preamplifier from the power amp section, so I don't think excess heat will be generated if used only as a preamplifier. Thanks for warning anyway Spinaker01.
