Which Mcintosh tube pre-amp?


Running the following system: Mcintosh MR85 / MVP841 > C15 > MC352 > Thiel CS3.6.

Considering adding some warmth via a Mcintosh tubed pre-amp, either C220 or C2200. 

I do not use vinyl. May add a streamer / DAC at some point.

Listen mostly to 50's / 60's jazz.

May I hear opinions re the C220 vs C2200 from Audiogoners who have experience with same or similar power amp / speakers?

Thank you.

Wrong stereo5, and I have proof below. 2 internal pics of the analog board side of the C2500 and C2600. Clearly different. ( so its not just the dac )

looks like they shrunk the C2500 circuit board for the C2600.   The guys in the McIntosh group claim that sonicly,  the C2500 and 2600 sound the same except the dac.  
Look at it closely, it’s just not the same board, everything looks better made on the newer board. Shorter signal paths. Look also at the 2 rights tubes, they upgraded the input / output modules. The C2600 seems to be a nice upgrade in that regard.

The ESS 9018 dac module on the C2600 is Wadia inspired ( since they absorbed Wadia Digital) . Big upgrade compared to the older BB in the C2500.
