London or Europe Anyone: Changing Voltage Again?

No sooner has the dust settled in my apt in NY that it seems cwlondon may be heading back to London or even Switzerland by the Summer.

The last time I went through this exercise, I bought a 240 V Euro spec Aragon 4004 MK II for a considerable premium. At the time, this type of permium was typical when manufacturers commanded a 50%+ higher prices overseas.

But then I discovered that it took about 45 seconds for another dealer to change voltage on my US spec Levinson 31 transport and my Jadis JPL preamp.

These days are most components easily switched? Could anyone be so kind as to glance at my system and advise me on switching or selling? The market overseas for US high end is thinner and much more expensive.

A side note, I just spoke with Audio Research who said my SP-11 could probably be switched, but also said that Richard Gray step down transformer could easily be used.

I thought that was an audiophile no no?!?!?

Any advice on voltage changes would be greatly appreciated.
