In my home office I have a little Onkyo (CR-N575) desktop receiver and it sounds okay at best. I keep wondering if replacing the default speakers would make much of a difference? I'm doubtful because the amp itself isn't great.
I clearly don't know much about amplifiers, but the specs say "RMS output power: 20W+20W (1 kHz, 10% THD 6 ohm)" which is terrible, right?
20W per channel at 10% distortion is pretty bad. The $350 powered speaker mentioned elsewhere in this subthread claims < 0.05% amplifier THD at 100W total power, and total distortion including the speaker of < 0.5% at 85dB SPL, which is an uncomfortably loud output.
Difficult to answer the question without knowing the OP's budget, but I agree on the Genelec line. $700 for a pair of their smallest powered speakers, and they sound great. What you are getting from these little speakers would have been considered quite exotic a few decades ago: individually-driven speakers with active crossovers and equalizers. For a couple thousand dollars you can put together a system that would have cost more than a house 25 years ago.
