Japanese Luxman Integrated Amps

I've used a vintage Japanese 100V Luxman MQ-70 tube amp with a step up transformer from AcuPWR (quality US made transformers) with good results. Many people frown upon using transformers as they can increase the noise floor, and they generally decrease the value of high quality aftermarket power cords since the power then needs to go through the transformer. But depending on your expectations, you can still get good results.

One thing to note is that gray market equipment is not always serviceable by Luxman in the United States, so always take caution/consideration in your purchase.

Any japanese (or other) 100 volt device can be played in USA using a small voltage 120/100 transformer: transformer plugged into 120 volt wall socket, transformer's outlet out: 100volt.

this one will work either 120 to 100 or 100 to 120

you don't need some big thing, these do a great job.

Warranty is void for sure, as shown a good transformer is over $1k

better off sticking to U.S , then another Big issue especially as of last 2 years customs duties and big time damage issues and refusal to pay on claims I know several people who got burned ,even banks refused to get involved .

Luxman USA warranty policy

I brought a used Luxman 590AXII and love it, but I brought it in the US with 120V. As @audioman58 and others stated, there is risk not just in buying it, but in selling it. I doubt you'll save any money in the short or long run.

I've not heard of any 'software' for their integrated amps, maybe for their DAC's?
