Hi, I've been looking into AV Receivers recently and think i'm going to go for the RX-V2600. I was just wondering if anyone has any experience with the following recommended speakers (I can't seem to find any reviews or information anywhere): - Front NS-525F - Center NS-C525 - Surround NS-M525 - Surround Back NS-M525 - Subwoofer YST-SW515 Details were found here: http://www.yamaha.co.jp/english/product/av/products/ht/rxv2600.html Many thanks.
