Buying a Luxman L505z from Japan

If the seller is legit, do not worry about the voltage,

I have a JVC TT81 TT, 100v, and use a decent but inexpensive step-down transformer (as do many people, for many audio equipment items). I've used it since 2019.

Size larger than your unit’s power needs (consider a larger future load)

they have one for 500 watts, this one is 1600 watts

Sure, it works with a transformer.  But if there is an issue with the unit do you want to deal with a seller Japan?  That is where a local (USA) dealer is worth their weight.  My Mola Mola Makua does not power up after a recent cable change.  I checked the fuse but no luck.  My dealer Bill Parish, GTT Audio, took care of the entire return and repair for me.  Smoooth.

Most of the naysayers have never tried to power a Japan amp with a step down.

I have done so successfully with Luxman and Accuphase. With the Accuphase's, I used a step down before having converted to US 120V spec. NO difference in sound. I second @elliottbnewcombjr 's rec. I have that very unit and have had great results. Enjoy!

@OP - buy in your local market - the compromises in using a transformer and lack of warranty and after sales service support just aren't worth it. At the end of the day  day, after you pay import duties and buy the transformer, how much are you going to save.

Maybe a 40% savings. If nothing goes wrong with the unit, a decent risk benefit proposition.
