Musical Fidelity M6-500i vs Kw - 500


Hello guys
I was browsing around the web today and stumbled across
the latest Super Integrated from Musical Fidelity .
This is a 500wpc into 8ohm beast similar in power to the limited edition Kw -500 , Some changes are evident between these models , The older Kw -500 has an external power supply and MM phono stage and single ended inputs only
along with 6112 milspec valves in the pre -amp section.
The Kw -500 was made in England.
The M6 - 500i has line level inputs only with 1 set of balanced inputs no valves appear to be in this unit making it solid state , The power supply of the M6-500 is onboard . The m6 -500i is made in Taiwan.
Has anyone else compared these two units ? Seems they each have advantages depending on your system setup.
I wonder if the new M6-500i would be much better ?

I've got a KW 500 that i picked up used a couple years back. I'm wondering how drastic was the improvement going with the revelation audio umbilical and Acrolink cords?

Where can I find info on the Acrolink umbilical cords? A web search does not bring them.

Thanks,

BTW, Pro-Ject has purchased Musical Fidelity. I think it happened in May, 2018. Also I had heard the Musical Fidelity M6-500i at a dealers place driving Vandersteen 2CE speakers. Tremendous amp, finess and power.
