The voltage standard here is 220v. I havent heard the JOR, as they are not sold in Finland. The m100plus sounded nice. I guess my question is more what does the JOR offer over the m100 for the extra money. I am only investigating a tip from someone that the JOR might be a good choice as an amp. It looks quite nice and the reviews sound pretty good. Also, although I gather opera are fairly well put together, the chinese construction bothers me a bit, and JOR sounds a bit more solid. They are essentially the same price for me if I buy the JOR in the US or the m100 here. That is used or almost even for new. But to buy the JOR in europe, that is probable not an option unless I find one used, which may be possible, but will require a lot of effort. I plan to visit my parents in early March and they plan on coming this summer, so import taxes are of no concern with me, used or new.
So it is going to come down to a matter of is it worth it to try to get one here and deal with voltage conversion, if it is a better amp for essentially the same cost. Of couse Ill audition it first, but the used m100 might not last that long.
