Are you wanting to replace your speakers? Or are you talking about replacing just electrical components?
If you are just talking about separates for amplification and you like Onkyo, you could just pick up the current Onkyo pre-pro(I believe it does have a phono input) and some amps. If you are wanting to buy a Blu-ray player, I'd recommend one of the new Panasonics. If you want to also be able to play SACD and/or DVD-Audio, then get the Oppo BDP-93 universal player.
