So what ever happened to Kinki Studio???

Hi Kinki fans, I have borrower Kinki EX-M1 for home demo. I don’t know what version is it because it has ON/OFF switch in middle from bottom.On the back I have DC filtering ON/OFF switch and also Link/Float switch with two clamps GNG and Earth. What the version of Kinki I got?? Thanks so much.Have look on this picture my look the same:

That's the current version with the better volume control.  Gold heatsinks designate the newest version. 

Many thanks jackd :) I’m glad that I have actual "version" of Kinki :-) I will return my borrowed silver version of Kinki EX-M1 next week. I would probably take EX-M1+ version in black. The black version is mandatory for me because all my gears are in black. I have played with idea take plus version for the future...???? due to preamp output for example to headphone amp or sub woofer or something similar. What do you think guys is it good idea? Many thanks for any suggestions :)

I own the original version of the M1, the EX-M7 and the current EX-M1+ in black.  If you need the extra features of the M1+ now or think you might in the future it is well worth the extra couple of hundred dollars.  I think you might have to spend quite a bit more to get a better sounding integrated. I have used the various Kinki amps with at least eight different pairs of speakers and haven't run into a bad match yet. If the sound fits what you are looking for then just go for it.  

Thanks Jack for feedback :) It sound awesome with Monitor Audio Gold 300 5G.
