As a stereo pair or surrounds?
The 302's are sold as stereo pairs really with an eye to being used as surrounds or as additions to an existing Premiere system- inasmuch as they are really designed to work with a sub. On their own, they'll be detailed and behave like most MS speakers until about 100hz where they obviously tail off a bit. From an MS perspective, the MS902 is a more natural competitor to the Wharfedale.
As TOF said. The 902's are great speakers.
The 302's are just not up to stereo work.
If the 902's are to much ££sh Have a look at mission or even eltax speakers.
For your price range Richer Sounds should have enough for you to look at.
i personally rate the Diamond 8.2s...a lovely natural sounding midrange whereas the Mordaunt Short 902s are more forward sounding, and give a metallic, brightish edge to vocals. The MS's are more detailed and enjoyable but the Wharfedales are more natural.
Up to you...ah don't forget the Diamonds can be sited right by a wall as they are front ported, whereas the 902s should be at least a foot away
If you can listen to the Diamond 8.1s alondside the 8.2s. I rate them much better. The 8.2s are the same design with a bigger driver which I think could do with a better built cabinet to control it. In a bigger room though the 8.1s may struggle to play loud enough for you. Whichever you choose they'll need good stands to get the best out of them.
