I would try the B&W 303. They have tweeter technology handed down from their Nautilus line and the highs are reputed to be very clean. I personally feel that they equal or surpass the 601S2 at a 50% lower cost. BTW, outstanding build quality and fit 'n finish by B&W for their entry level speaker.
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!
