Which preamp is better C50 or C2500 for MC402?

I have a 402 and have it coupled with a Audio Research LS26. I had a MX135 prior to the ARC, I did look at the C2300 when I bought the ARC. My point is not to steer you away from McIntosh as I really do appreciate the sound and build quality of their products. But my point is that getting a tube sound influence vs. another solid state, I believe brings the 402 to a new level of performance. Maybe that helps you, or not, but I am suggesting a stronger look at the C2500. YMMV of course.

The C50 and C2500 are roughly equivalent in price and features. As noted by the others, it depends much more on whether you want to go with the tube sound.

I had a C2300 for 6 months and loved it. But. It took about 3 hours or so to warm up and I couldn't leave it on 24/7. It also didn't reproduce some electronic instruments quite as crisply as I prefer.

So, I turned it in on a C50. Does the C50 sound as good on acoustic music from vinyl? No. Does it outperform with Al DiMeola, also from vinyl? Yes. Is the on-board DAC useful? Yes. Do I use it much? No. Does it warm up fast enough to allow me to actually listen to music rather than wait? Absolutely!

Both are superb units built to serve the same market differently. Give some thought to how you listen and what you listen to. Let that be your guide.

Good luck & happy listening!

I know this is an old discussion but I’m actually facing the same dilema as vinny8888 at this moment. Want to buy a good preamplifier and stay with McIntosh and my 402 but do not know if I want to go the tube (c2300) route or (c50), - not able to demo them actually -. I have had both tube and ss gear before so do not have a preference and I get effischer’s point, much depends on the music you play; I play mostly classic rock 60%; some jazz 25% and other stuff 15%, recently much internet radio (via cambridge streaming) and vinyl and cd’s (via oppo 95). So theo, and others my question is: which one is best taking into account this music I prefer? Agon members input is much appreciated. By the way: Speakers are B&W 804D2.

Or go with the Aesthetix Calypso and go to a whole new level.
I have Mac 501's with the C2200 and have heard this combo ( Aesthetix Calypso )and wow do they make a great PRE..

Thanks russe41, was also thinking of the Audible Illusions 3A, some say it is also top notch if I decide to go out of the McIntosh circle.
