Just as a quick response to the Epos recommendation - I purchased a pair of Epos 3's for my mother in-law, which she still has and enjoys. Good for the money, but will not hold a candle to the Era 5's. Even for the money I'd probably look for a used pair of Soliloquy Sat 5's before getting a pair of Epos 3's. Have not heard the larger Epos, but would assume they'd be bigger than you'd like for the application of desktop duty.
