RE: Outfitting AC to 220V in USA


I live in Hawaii and have the opportunity to purchase an ASR Emitter I amplifier (220V version) for bi-amping. My AC is currently at 120V but my electrician tells me he can run a dedicated 220V line from my dedicated audio circuit breaker to power the 220V amplifier. The amplifier's power cord has a standard 15 amp IEC and has what I believe to be a German Shuko two prong plug.

I contacted a business that specializes in selling European wall outlets, transformers, and outlets. The representative recommended that I pick-up a transformer to convert 220V to 120V to power the 220V amplifier.

I would prefer not to purchase a transformer and would rather (if possible) have an electrician install a dedicated 220V line and install a Shuko wall outlet, that will enable me to use the amplifier's power cord and go directly to the wall outlet. Is this possible? If so, does the standard German AC power line or shuko power cord have two positives, one neutral and one gorund OR two positives and one ground OR two positives and a floating ground?

If a transformer is the only alternative, can you provide me with a brief explanation why. I do not know if I will have phase problems.

I would appreciate your thoughts to my questions. Thank you in advance for your assistance.

Go with the 220 volt outlet and make up a new power cord with plugs that are adaquate at both ends. Many Europeans who move to the US use all their equipment this way with no problems. Many believe 220 sounds better.
Any electrician can install a dedicated 220V line and install a Shuko wall outlet. All you need is the room in your AC box to accommodate the circuit breakers. I don't know the rest of the answers to your questions however it's very basic electric information. I'm sure other members can answer the remaining questions.
Can anyone tell me if European voltage is single-phase 220V? I thought our own 220V supply was twin-phase. Do I have this right, and if so does it make a difference for an application like the OP's?
