I am looking to get myself a hi-fi system. I am really inexperienced and I need a good loud and clear setup to get my walls rattling. I am sold on the B&W 685 S2 speakers and I might get an ASW610 sub later. The problem is that I do not know what amp I should get for my setup. I am looking at Arcam A19 and Cambridge Audio CXA60. For reference, I am currently using Razer Leviathan soundbar as stereo speakers. I have never had the chance to listen to high definition sound systems.
If you are serious about 'loud and cleat' then your choices above are, frankly, hopeless.
The speakers are not very sensitive and known to be quite difficult to drive with a nasty impedance dip right in the middle of the bass region. This means any amplifier you choose will have to work pretty hard just to play at normal hi-fi levels. You are, literally, throwing watts away.
In such a setup there will be little left for when you want to turn it up and you will rapidly run out of power, so not very satisfavtory at all. One caveat though, it kind of depends on what you think of as loud.
Given your selections, I guess you are looking at £800-£1000 for amp and speakers but before making any suggestions it would be good to know what you plan to use for a source and get a little more detail on your budget.
