I have a pair of Infinity primus 363’s that I use for two channel and multi channel, I will say that for the price the p 363’s are a darn good speaker, I recently bought a pair of wharfedale Diamond 220’s online, the 220’s are pretty good but they DO NOT compare to the Infinity p 363 in my A and B test, that said... I returned the wharfedales, the p 363 sound really nice with a small tube amp.
Another good sounding speaker is the revel f12, I bought a pair used a few years back for $600, these sound even better than the p 363 if you can find a pair used.
