At the moment I'm running RX6 fronts, RX Centre and RXFX surrounds with a BK XXLS400 paired with a Yamaha RX-V3067 and the overall sound quality is just superb! Really happy with this set up, could not fault it one bit. If anything, I gotta keep the sub on low just under half way as it's a really noisey bugger. The MA Silver RX are probably the best speakers I've ever heard. They're speedy, aggressive, neutrally tonal yet well detailed and very dynamic. Can't fault them at all. I'm going to be decorating my living room pretty soon and I have a choice of building a 5.1 budget/entry level system there or.... Move my current MA Silver setup downstairs to the living room. BUT... If I went this way, what 5.1 system should I be looking at that would better the already stunning MA Silver RX series and would be noticeably better? I ask because I went from a Bose Acoustimass 10 to the Kef KHT3005SE and the upgrade was very noticeable, The Kef system was much better overall. I'd say percentage-wise this gave me roughly a 40% upgrade in sound quality overall. It really was heaps better than the Bose. I then went from the Kef 3005SE to the MA Silver RX series and allthough this was an obvious physical upgrade, with the Kef system sounding as good as it did the MA Silver RX series probably gave me only 20% upgrade overall in sound quality compared to the Kefs. No doubt these are Better yes, but not by a "massive" difference. So with the current superb setup, if I wanted to upgrade and "Feel" the difference at say a 40-50% upgrade in sound quality, what sort of setups should I be looking at?? Obviously the most important factor here is Money!!! If I said my budget was around the £2.5k-3k for the front 3 and the rears. (I'll probably keep the BK sub as it's more than powerful enough) I've seen some speakers by PMC/Spendor/Dynaudio/Linn etc, but they have so many different ranges it's hard to distinguish what's on par or on a level above the MA RX range I already have. So if you had my budget and was looking for a real noticeable step up from the RX range what would you go for?
