Upgrade for home theater - Klipsch 5.1.2
I was looking for a recommendation about upgrading my home theatre to the next level. Right now I have Denon AVR-X3200, Klipsch Rp-280F, RP450C, Rp250S, RP140SA, R115SW and Fluance RT-81. I was considering buying a second R115SW or adding amplifier maybe Monolith 2x200 Watts (I saw that in the best-refurbished system you can get around 500USD). I definitely was thinking about reasonable upgrade around 500USD. The other question would it be beneficial to replace the Denon 3200? If yes what would you recommend? I noticed that for those Klipsch people are using something better than 3200.
The other question, I'm from Poland so the input voltage is different do you think that having a special transformer that will change the volage from 220V 50hz to 110V-120V 60hz could have influence for working of the system? sound quality or any other issues? (for the pre-amplifier or for Denon?)
