Kinki Studio EX-M1 200wpc Integrated Amplifier

Great news, Nonoise. Congratulations!

Regarding a question I posed earlier in the thread, does the gain seem to be either particularly high or particularly low, as judged by what part of the volume control’s range you find yourself using? As I mentioned in my post on 7-8-2018 there seems to be conflicting information regarding gain, none of which seems consistent with a moderate or typical value.

Also, in my post dated 7-7-2018 I had wondered about the possibility of transient intermodulation distortion resulting from what might be incorporation of a lot of feedback in the design. I think a good test for that would be well recorded solo piano music having lots of sharp transients.

Enjoy! Best regards,

Hi Al,

Boy oh boy, I am enjoying this. 😄

The only thing I can say is that it takes just one click (about .5db) for me to start to hear something coming out of my speakers. What used to take to get to satisfying levels with my Marantz (-43db), I’m now getting at -20db, or thereabouts, if I’m thinking correctly.

My Marantz has 200 steps with each at .5db (from 100 to 0, or max) and the Kinki has 256 steps, each at .5db (?)(from 0 to 255).

The readout is at 20 and I’m hearing everything. I was perfectly content at 20 and it was only after trying out some jazz that I realized the SPLs were much lower than what I’m accustomed to. Turning up to 30 just made it all the more realistic sounding, along with the SPLs that I’m used to listening at.

Going through my CD collection I’ll make sure to try out some piano and let you know if it sounds good.

All the best,
Nonoise

OK. So if I understand correctly setting the volume control to around 30 on a scale of 0 to 255 seems about right on the recordings you’ve tried so far.

That suggests the gain is fairly high, and means that the sensitivity spec I referred to in my post dated 7-8-2018 is probably inaccurate, with the sensitivity numbers being lower than indicated.

It also means that using the amp as a power amplifier, in conjunction with a separate preamp or other component providing significant gain ahead of it, might be problematical. I had been toying with the idea of using this amp as a backup for my VAC power amp, and/or rotating it with the VAC now and then as a fun experiment or for a change of pace. (Using the Kinki as an integrated amp without a separate preamp would not be appropriate in my system, because I would not want to be without the signal processing and other functionality of the DEQX HDP-5 I use as a preamp).

Thanks again. Best regards,

Hello Al,
From a review I read (can't find it now) there is someone who noticed the same thing you have and asked to have the gain reduced so as to not come on so much at lower settings and they adjusted it for future models. 

Maybe they could do something similar for you. Alvin is very responsive and since they make them as they're ordered, maybe some accommodation can be at hand.

All the best,
Nonoise

Thanks Nonoise.  That's good to know.  I'll be watching for further reports about the sonics of this amp from you and others.

Best regards,
