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.

I have no direct experience with the particular gear referenced. When you double the power of an amplifier, you only get a 3dB increase in loudness. Generally, this is considered to be the lowest significant perception in sound increase most people can discern. So unless you are on the razor's edge of what is needed, it is unlikely to make a significant difference, since this will yield only a 50 percent increase in power.
