Used Rega Planet or Apollo vs. affordable PC audio


I am just starting out on this, and I have spec'd out a system that I am thinking about buying - iTunes running ALC to an Airport Express, then optical thru a Van Den Hul Opticoupler to a MF V-DAC. I am curious if anyone thinks the sound will beat a used Rega Apollo/Planet, or a used Rotel RCC-1055; that's right, I like changers. Sorry. Also thinking about adding a Monarchy DIP Classic to the signal path later on. Current amp is a 15 year old Yami, running B&W 685s and a HSU VTF-1. Thanks.

think catastrophic flood or lightning storm that sends electrical surge spikes thru anything and everything plugged into a wall. Its happened to my sister and a friend of mine (separate occasions). I think having the CD is the ultimate back-up, but I still do have a ton of download-based 128 and 256 .mp3's files in my library. I wish I could get them upgraded, but its not possible. I can definitely tell the diff between 128, 256, and lossless, when played in sequence, but picking them out in a blind test - haven't tried yet.
A fire would also wipe everything out too.

MP3 is a different story- although 256k mp3 is getting pretty transparent but aac is substantially better and almost completely transparent @ 256k imo.
Fire BAD!

I have everything at 320 mp3, chose mp3 because most newer cd changers can read it. dunno if they can read 320 kbps tho! I don't think as many changers can read .m4a (.aac), have you burned your .aac files to a disk and played it in a player? Doesn't matter for me until I get something new, my Yami changer is from 1993, so I am iPod based until I figure something out.
