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!

do you know the value of the second fuse? I know one is a 1.6A 5x20mm and I like to replace with Furutech blue fuse. the other one I didn't check yet. So, do you recommend use a 2.0A fuse instead 1.6A
I have a Marantz PM-KI Ruby and I like to replace the power supply fuse and power cable. Somebody knows the oem fuse measures?
I was looking for Furutech fuse and PS Audio power cable.
I already checked and it uses a 5x20mm 1.6A fuse. This Marantz PM-KI Ruby definitely needs a High End Fuse.
