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!

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 
@jl35 i just ordered the Herbie’s puck gliders to use under my spikes. Hope they live up to the hype. Cheers
guys, if you’re using spikes you have to check out the herbie’s puck gliders. Not only do they make moving speakers super easy but also improve the sonics substantially. As far as I’m concerned, this is it for me.

perhaps, I may get a turntable at some point but the rest of the chain are here to stay and I couldn’t be more pleased with the PM KI Ruby. Cheers!
