Step Up Transformer 100v

Someone at Naim told me I'd need a 500v step up transformer, so I thought I'd be OK with the EHU600. Am I wrong, however?
Thanks!

Multi input voltage transformer made by SWALLOW Company.
These Transformers are made in Japan.
SWALLOW SU-2000 (2000 WATTS)
SWALLOW SU-1500 (1500 WATTS)
These transformers have three pin socket for earth.

Bigger transformers have a lower impedance, thus less likely to create distortion at higher draw. The downside is that bigger transformers will have a higher "idle" current and will cost you to run.

At 16 Kg for the 2000W Swallow, that looks more like a "converter" or autotransformer, which offers no isolation and noise reduction. They are quite efficient and do the job.

Not sure of these step up/down transformers will do it for you. I am using a 2000 watt transformer here in the US with my Swiss made coffee machine and it is awesome. I also plan on using a 1500 watt for myGerman built 230 volt audio equipment.

When it is on and at idlde with no current source on or in use, the 2000 watt transformer only used 6 watts as measured with my power usage meter. When the coffee machine was making coffee or when it initially turned on, it surged up to 1450 watts. This transformer is also very quiet. I was stationed in Germany for many years and I used many a stepdown transformer for US made equipment. I can tell you from experience, this is really a quiet transformer. I only hope it will work for you.

Good luck,

Thanks again for the replies. The Swallow transformer looks very good but it's pretty heavy and expensive. I have found another one, however. It's supposed to be made for audio, runs quiet I am told, and is rated at 1500v. Here's the link:

It's made by Noguchi Transformers. Its pretty expensive at 20,000 yen. Thanks!
