110 (or 120) vs 220


Hi,

IF an amp can operate at both 110 and 220, and a dedicated circuit is being installed for that amp, is there an advantage to a 220 v circuit? Or is the answer "it depends on the amp"? Or is the answer simply "no"?

My reason for doing this is that my tube amp is rated at 35 watts / channel. I'm buying new speakers after having my Paradigm 5se's for over two decades.

I naively thought if I doubled the voltage I could ~double my available power (~quadruple at 4 ohms?) and that would vastly increase the pool of speakers I could choose from (e.g., Totem, Magnapan).
Hi jea48,

That's a pretty thorough response - thanks. If it is against code I won't do it.

I presume that IF the unit was designed to run at 220-240 (as well as 110-120) that most of your concerns would be alleviated? Running other equipment off of the same circuit is theoretically possible with a voltage converter. But ya, I'd have to give up my new Zu mains cable. :(

Btw, thanks for pointing out that my country doesn't show up. I live in Canada and did enter that info, but for some reason it is not coming through on Audiogon. I've sent an e-mail to  support@easypost.com.


Ok. If the amp isn't designed to do both with no modifications from me then I don't want to do this. (I have a call in to the manufacturer).

I have a CPAP machine and it will automatically switch from 110 to 220 it I switch the power cord. Guess it isn't so simple for an amp!

For the interconnects, I was referring to a converter that you plug into the wall and then you plug the ancillary equipment into it. The converter takes 220 volts from the wall and converts to 110 for the equipment to use.
