Buying a Luxman L505z from Japan

Not to suggest you SHOULD buy from Japan, but... The Luxman integrateds have relatively low power draw, so a step down transformer is not difficult.  Power draw is pretty universal so you should be able to gauge what you need from the US specs.

Unlike Accuphase products, the internal power transformers are not universal.  Many accuphase integrateds can be opened up and reset for different regions, but sadly not Luxman integrateds.  

@erik_squires when you say low power draw - what do you mean by that? 

Look here for an example.

On the right is a section "Power Consumption" which lists the absolute maximum power this unit can consume.  For the current L-505z that’s 330W.  This is honestly not a lot, in the era of kilowatt amplifiers. So any step down transformer of ~ 500W (i.e. VA) is probably good enough. 

Many of these would work: https://amzn.to/4nb0Ed8

Just walk away from that thought. Don't do it. Ignore all thoughts of this kind, buck up and pay for US/ Canada version. 

I have the Luxman L-509Z direct from Japan. I use a step-down transformer, and I can usure you it DOES NOT affect the sound in any way!

I have 47 years in the electronics industry as a radio technician, and I have built and modified many amps and various other stereo components.

The Japanese voltage version of the Luxman works flawlessly in the USA with a transformer.

You can listen to people who think they know or someone who actually has the setup in the USA...your choice.

I enjoy my $14K amp for the $7K I paid...
