Hello, If I could order an Onkyo 875 or 905 from the USA, will there be any issue with the formats and or electricity? i.e would it play video sources in the UK (PAL etc.) and would it accept 220V electricity? If it can only work qith 110V then how about using an adapter? Any other concerns? The reason is that the 905 is going to sell for $1999 (about £991) while here it will cost £1400). Even if shiping costs £100 that would be £300 savings which could go towards a pair of good speaker stants
