McIntosh C2300 vs C2500/C2600 A/B Comparison

Congratulations!  I feel that was a very good call on your part.  No fuss, no muss and minimum bucks.  I never got to tube roll my C2300; turned it in on a C50 for reasons not relevant to this thread.  I'd always wanted to try the Telefunkens; it was superb with the stock tubes and I suspect it would have been perfect with matched Telefunkens.  Perhaps sometime in the future. Have fun!

I think I remember reading your post about the C50 vs C2300 in the past. I also think we chatted before.
Thank you! I'll be staying in this weekend listening to music and watching TV.
Be safe everyone!

 I rolled some smooth plate Telefunken tubes in the MM and Line Stage of my C2300 and the sound is very lush and sweet.

Amprex, Mulard, Volvo, RCAs.  ALL wonderful upgrades from stock Mcintosh tubes. All sound a little different. I've had both 2300 and 2500 still have the 2500. Very close sonicly 2300 and 2500, but tube rolls I noticed more so with the 2500.
Silvania, (brighter) solvex (brighter).  There is something about Tellies and Mcintosh, Just work.  I have Mx110s, a C11, C20s, (and had a) C22
All like Telefunkens, and RCA black plates. RCAs something about the mids  and that valve.. Holographic, comes to mind

As I type I been using Amprex (vintage) valves a matched set of  date stamped 6. I'm a MC and MM guy nothing fancy. Old Thoren, TD124s and Russco Broadcast units. ZERO floor noise with either.  I'm telling you they are a real game changer too. I like them in th AUX section on the 2500, adds a  snappy sparkle but not a brightness. Island music,
Salsa, smooth jazz. very nice
