Ian,

I'm not sure how Bose systems are marketed in Russia, however, in most other nations they have a fantastic return policy. If you do not like what you hear, you have 45-days to return the system for a full refund--no questions asked. You may want to check into that policy and see if it is in effect in Russia.

Good Luck,

Gary cool
