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 ?

Hi I have been sitting on one of these units for a while now finally picking up speakers that need the power. Curious about what carts are being used with mm or mc. 

Thanks

Good to read about MF being a sonic match w/ Thiel speakers.
Additionally, another + vote for Anthem 225 integrated amp being a sonic match w/ Thiel loudspeakers.

Which cables/cords are you guys using w/ your MF products?
Keep me posted & Happy Listening!
I just saw one posted on Audiomart, anything under 3K for this unit is a steal, especially if in good shape. I have one and I have put a ton of other products up against it, and it win's out every time. Shear raw clean detailed power is amazing, and these things where built to last. 
I still have my kw 500 although it is sitting in reserve now waiting until I can assemble it into a second system. After 10 years I finally replaced it with the new Nu Vista 800.   The KW 500 is truly an outstanding amplifier. While the Nu Vista 800 is indeed better, if you can pick up a well cared for kw500 for a good price I would jump at the chance.  Transparent audio cabling has worked beautifully for me with my musical fidelity products.   One thing I would suggest is not to leave it powered on all the time. Although those tubes will last a long time they will do better if you shut the unit down when you're done listening. 
arsh: Good point, I just recently heard the Nu Vista and I was thinking of upgrading but not home enough to justify the cost. Another Int. Amp I like is the new Hegel H360 on par with it and sonically a improvement but not in sure raw power that is for sure.
