MC901 monoblock tube matching Q

I'm new to tubes... I have 2x MC901 monoblock amps. Each amp requires 8x KT88, 4x 12AT7, and 2x 12AX7A tubes. Do I need to match all these tubes? And do I need to match tubes for both amps together (i.e. 16x KT88 matched, 8x 12AT7 matched, and 4x 12AX7A matched)?

Thanks for your help.

hi,

Interested to know how your McIntosh tubes are working in the 901. Have you considered changing them out for something different?

Have you had any tube issues?

What speakers are you using?

I have 901s and have thought about trying new small tubes.  Not sure how much an impact using non-Macintosh tubes would have on the sound. I'm using b&w speakers right now, 802 d3.
