Tube rolling on MacIntosh C2300

I want to try out some new tubes on my C2300 preamp. I only have one source, a DAC/Streamer and do not have a turntable. The preamp has 6 tubes of which 4 are for phono (2 MM and 2MC). Should I change the phono tubes as well or since I am not using the phono stage, it will make no difference?

Thank for all the great suggestions. Will definitely look into them. It will be nice to have quality alternatives instead of Telefunken which is crazy expensive.

I believe you can shut the phono section off, so, in effect, you will have 4 spare tubes. FWIW, I swapped the factory tubes on my C220 for Mullards, current production. They are quieter and slightly warmer sounding than the stock tubes.

I second the suggestion for the Amperex Medical Grade Bugle Boys. Years ago I too had a 2300 and used these tubes with great results.
