McIntosh MC240 & Emotiva XP3 for HT - Recommended?

I want to upgrade my HT setup. Currently I've Kenwood VR4090 receiver, Tyler Acoustics Linbrook System II speakers (Front & Center), JBL S312 (Rear), Oppo 93, & Nakamichi RX-505 Tape Deck.

I started with a budget of $2k for the Amps but I guess, I might have to stretch it a bit for the love of Tube Mc based on several reviews here.

I'm thinking of using Oppo 93 Analog feed to existing Kenwood receiver (config as Pre/pro) & connect to
- Mc Tube Amp for Stereo (say MC240/ MC275)
- Emotiva XP-3 for the remaining 3 channels

However, I'm not sure how will that work since the tube amps are rated as 40W & 75W respectively whereas, XP3 is rated at 200W into 8 ohms.
- Will the surrounds & center overpower the fronts during movies?
- Are the speakers (Tyler - Linbrook) good enough for the Tube Amp?
- Do you recommend any alternatives?

Here's my speaker specifications:-
Tyler Acoustics - Linbrook System II (Front & Center)
Frequency Response: 32-25k
Sensitivity: 89db
Impedance: 8 ohm
Power: 30-250wpc

JBL - S312 (Surround)
Frequency Response: 35-20k
Sensitivity: 92db
Impedance: 8 ohm
Power: upto 250w
