Size, drawn to scale

Both amplifiers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

One scale for both, aligned at the back panels the way they would sit against a wall, so the deeper one visibly stands further out.

Balanced connections

Both have balanced XLR connections. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more it is worth. Whether it also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same either way.

Verdict

No single best amplifier here. What decides it is what you have to drive, what you need to plug in, and how much of the system you want in one box.

Area	Better	Why
Power	evenly matched	Effectively the same output - 220W against 200W into 8 ohms is under 1dB, which is not an audible difference in loudness.
Grip on hard loads	B	Rotel Diamond RA-6000 holds up better into a 4-ohm load: its output increases strongly to 350W, where the other increases strongly. That matters with demanding speakers far more than the 8-ohm figure does.
Noise floor	B	Rotel Diamond RA-6000 is the quieter design on paper - 103dB against 80dB. Audible mainly with sensitive speakers in a quiet room.
Built-in DAC	B	Both decode on board, but only Rotel Diamond RA-6000 handles MQA.
Streaming	evenly matched	The same streaming platforms and services on both.
Room to grow	evenly matched	The same expansion options on both.
Price	B	Rotel Diamond RA-6000 costs less - $4,500 against $4,999 at list.

A Michi Prestige X430 B Rotel Diamond RA-6000
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

Rotel Diamond RA-6000 has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - Rotel Diamond RA-6000 is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating.

What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
