120Volts to 220Volts?

I have gone thru this as well. If you are happy with the equipment, I would suggest you go for the transformer. The frequency is unimportant as it only effects synchronous motors found in (most) turntables. I know some CD transports which also have these, but, Arcam is not one of them.

You have a few options here, you already mentioned the option of a transformer. If you do this, you should probably consider a servo controlled variable transformer, which will ensure that any variances in the source voltage will not translate to your equipment. For example, using a static transformer, 240 volt beceomes 120 etc. This can become problematic when you have spikes on the line. I have bought some servo controlled transformers from www.overseasdvd.com, they are fiarly inexpensive and work fine for me.

Another option you have not mentioned is using a PS Audio PowerPlant. These are wave form regenerators that will recreate a nice, clean 60Hz sine wave at 110V. The cool thing is that the input voltage by default is 110V, but is switch selectable between 110 and 220. While it is an expensive option, it would make for great, clean 110V power. I use a PowerPlant 300 in my main system before the CD Player and Pre and it is a remarkable piece of equipment.

Hope that helps.

I would go for a transformer if I like the equipment.
I am living in Hong Kong (220V 50Hz) Many audiophiles here use Japanese or US local products (110V). Some better step down trnsformers in Hong Kong are selling less than US$100.
So far everyone here using 110V equipment seems to be happy with such approach.

Thanks everyone for great advice. Actually, the gear belong's to my girlfriend - I doubt she will be wanting to get the PS Audio 300 - a bit too expensive for her. I do use one myself for my gear at home though. The transformer options sound good. I'll check with Arcam though to see if there is any internal switch. Thanks again!

Outlier, if there is no internal switch, possibly there are contacts on the transformer , where the unit could be soldered to and hence rewired for 220VAC. Ask Arcam for that possibility as well. Any technician , adroit with a soldering iron, could do this for you for little money- if he knows the right contact points.
