Marantz PM Ki Ruby vs Musical Fidelity M6si

I have narrowed down the options to drive my Dali Rubicon 5s. 
I’ve heard that unlike most marantz reference series gear, the ruby is not as warm. Also, uses a Class D instead of the usual Class A or A/B.

interestingly enough, I tried the musical fidelity m5si and it sounded quite good with my speakers.  It wasn’t as bright as I expected. It was lively yet warm. My budget allows me to go for the next level, so I’m wondering if I should go for the warmer Marantz Ruby or the MF m6si instead. 
If you own either of these amps, plz could you share your thoughts? There aren’t many reviews and really need your help. thanks!

Well congratulations on the new addition to the family!

There was some break-in time, I recall more extension in bass & highs after a few weeks. 
In one of the posts above, nonoise mentions power conditioning: I can attest to the fact that the Marantz likes & appreciates clean power.The amp is revealing enough that you should be able to hear a difference in ac cables: A Pangea will make the amp sound dull and lifeless; the Amazon iron lung jellyfish  (<$20) really opened up my system:

There's hundreds of others, I stopped there as I'm satisfied. For now :)

FWIW, I am using the Canare 4s11 speaker wire & Audio Envy interconnects from the Ruby SACD. An Audioquest Powerquest 3 protects all from voltage irregularities. Happy camper here.

Hope you enjoy the amplfier as much as I have mine.

@p3ga funny coz I just ordered the canare 4311 after a lot of research, and turns out it’s your recommendation.

I’m absolutely loving the amplifier. It’s opening up nicely, I can already hear a great deal of difference. Highs and mids are opening up and bass is punchier too.

That $20 power cable really make such a big difference? It’s so cheap that I cannot not try.

different topic, do speakers on spikes sound better than those on rubber feet? I have my Dalis on herbie’s rubber feet coz I have wooden floor. I’m wondering if I should buy those spike feet if they’ll make them sound better. Any thoughts?

my Dali's (many pairs) have always sounded best on Mapleshade brass cones, but the included spikes sounded good too...some prefer no footers...

@jl35 thanks for your response. Any recommendation for feet under the Dali spikes? I don’t want to damage the floor but at the same time don’t want to compromise on sound quality either.  I was consider the herbie’s pucks but there are several options on amazon for a lot cheaper. Having a hard time making up my mind.

I use the Dali’s into the wood. In other systems I’ve had good luck with Adona brass pucks
