Tom, it appears that you have an excellent setup, so the first question might be would the $4,000 that you "have to spend" be better spent on something more beneficial to your present or future well-being than more audio equipment.

Your M100s are of average sensitivity and are quite easy to drive with quality amplification such as your 3808 provides. It's ironic that the one area of audio which is governed by legal regulations(the amplifier power regulations of the FTC)often is a subject of suspicion. As the linked lab tests show, the 3808 is rated slightly conservatively. At a typical comfortably loud average listening level your M100s use about 1 watt. Brief peaks require much more of course, but the 3808 provides over 20dB of headroom above the average level.

If you listen to pipe organ music requiring more bass than the already excellent M100s provide, or watch movies having extensive very low frequency effects, then a sub such as the EP800 would be of significant benefit to your listening experience.

Enjoy the music, not the equipment.
