McIntosh C2300 vs C2500/C2600 A/B Comparison

I have a C2500.  I can't say enough good things about it.  It is the finest sounding preamp I have ever owned and it is dead quiet.  I bought the C2500 over the C2300 because I needed the processor loop which the C2300 does not have.  I would think either one would be fine although I like the way the C2500 presents the music.

Thank you stereo5,

Even though it's hard to describe sounds, in what way does it present music differently than the 2300? 

To me it is the ease in which the music flows. The built in MC preamp sounds very good.  I feel there is a little more frequency extension on both ends with the C2500.  I think of it as a tweaked C2300.  If there is a big difference in price, go with the C2300, if it is around the same price, I would go for the C2500.  The dac chip in the C2500 is the Burr Brown pcm 1792 chip set. It’s decent but not as good as the dac in my Esoteric SACD player.   

Thanks again!
I'm going to roll some tubes as well before pulling the trigger on trying the 2500.

On the C2500, verify that the Firmware has been updated the latest version.  If it has not, don't let that be a deal breaker.  An authorized Mcintosh Dealer can do it or Mc. Tech Support over the phone. Good Luck.
