The Aegis One is very good for nearfield listening. I have considered it for my home office as well. However, if you plan to set up these speakers at any realistic distance away from the listener (say 5 feet or more), I don't think these are the best choice. Of the ones you've mentioned I've listened to the Tannoys and the B&Ws. I have listened to other speakers by PSB, and have to say I don't care for them very much (obviously when talking about speakers it's very much personal preference). I would favor the B&Ws overall.
Best Budget Bookshelf Speakers?
I'm looking into buying bookshelf speakers for a bedroom system, and am trying to decided between PSB Image, Tannoy mX2, Wharfedale Diamond 8, Acoustic Energy Aegis 1, and B&W 303's. I'm currently running a Sony CD/MD deck through the Musical Fidelity X-10D, into an Onix A60 integrated amp, using Wharfedale Opal 30 speakers. Besides the speakers mentioned above, any other recommendations would be much appreciated (Mission, Diva, etc???). Thanks!
