Tube types

Hi all
My Octave HP700 pre uses, amongst others, a Telefunken ECC88. Can I use an E188CC?
If not why?
Am I right in thinking the E88CC is far superior to the ECC88?

Thanks
Rich

I guess tube rolling could potentially be rather expensive in order to find the best combination Have you guys found that switching to premium tubes has been a significant improvement?

I had ARC SP-9 MKII and MKIII. The E88CC sounded better in the MKIII, the ECC88 better in the MKII.
