Moving from 120 VAC to 220 VAC operation on Krell monoblocks



Just read an interesting article from MBL regarding audio benefits for operating power amplifier at 220 VAC on dedicated electrical circuit. http://www.msbtechnology.com/faq/how-to-wire-your-house-for-good-power/
 
Also read on the Gon that Dan d’Agostino has voiced the sound of the FPB amp series by operating them at 220 VAC. 

I currently own a pair of Krell FPB-350 MCX monoblocks which operate on 120 VAC dedicated circuits (14 gauge wire). Contacted Krell and they indicated dip switch positions for operating the amps on 220 VAC. The MBL paper suggests to wire 220 VAC dedicated circuit using 10 gauge wire to reduce electrical noise and amplifier modulation of electrical circuit.

While the theory seem to be valid and before rewiring my dedicated circuits, I would like to have some Krell amp owners comment on the benefit of going to 220 VAC operation for those who have performed the mod.
