The C2300 is one of the very best preamps made, period. It has a truly superior phono section and is beautifully musical. It even made Harry Pearson's (RIP) reference system for a while. The C2500 is the same unit with Mc's fancy DAC added for good measure. The C50 is their top solid state single body unit and also has their high end DAC.
I loved the 2300, but couldn't handle how long it took to warm up @ 4 hours, so swapped it for the 50. It was a good compromise for my system, but I wish I had the scratch (and space) for the C1000. That way I could get the best of both worlds!
Since you have digital sources, if you go tubed Mc, I suggest you go for the C2500. That way, you can compare the AR DAC in your disc player to the Mc DAC and see which one you like better.
Good luck no matter which way you go and happy listening!
