Apples to oranges. So much is different between them, the least of which is their power ratings. It's a fairly big leap to assume the VAC Avatar Super sounds anything like the VAC Phi monoblocks.
The Moscode, Belles and TRL will be affected by the preamplifier used.
The speakers you intend to use will be a significant factor to the answer.
I have owned a VAC Phi 110/110 and presently own a Moscode 401HR. I've never heard a Belles 350 nor a TRL 225.
Honestly, I don't know where to begin answering your question except that I would recommend choosing your loudspeakers before your amplifier.
