Adding an Accuphase A-46


I'm considering upping the power of my Accuphase E-560 integrated (30W pure class A) by adding the A-46 (45W) power amp. The E-560 would then operate as a preamp.

Has anyone tried this configuration? Would the additional 15W make a signficant difference in controlling excess bass and adding body and detail to the sound? Speakers are ProAc Response K6.

Many thanks.

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.
OK cool, that makes sense and would be a good feature option on all integrateds that have pre-outs.
