I'm looking to buy a new hifi system. I've demo'd a few things but the NAD C320BEE amp and C521BEE have caught my eye together with Monitor Audio's Silver S1s (or possibly S2s?). My room is probably medium sized (18ft x 9ft and 9ft high) and I was wondering whether splashing out for some floorstanders (AE evo3s for budget or maybe MA S6's) might be a better option. Actually what I really wanted to know was whether the NAD components and the Monitor Audio speakers will work well together, and if anyone knows of a shop that actually sells both brands so that I can actually go in and have a listen to them. (Also would it be worthwhile going for the more powerful C521CT amp.. 80 watts rather than 50, although the S1's are rated at 90dB/W/m so they shouldn't be too hard to drive... in theory) Any thoughts are appreciated.
