Kinki Studio EX-M1


I’ve always wanted something simple and not a jack-of-all-trades when it comes to my stereo. KISS (keep it simple, stupid) is something I use in my approach to most things in life. Why overcomplicate? The Kinki EX-M1 is just an integrated, and that’s not meant as a pejorative. There’s no DAC or streaming capabilities, or room correction algorithms built in, and it won’t fold you laundry. There are 4 inputs out back, three unbalanced (RCA) and one balanced (XLR) which I’ve read is a simple and not a true balanced. Either way, it adds another type of input which can come in handy. The binding post are copies of WBT versions and are a joy to work with.

It has a frequency response of 10-150kHz (+/- 3db) and outputs 215W into 8ohms. It retails for approx. $2,200. Here is a link to more specs:

Because of it’s silvery finish it has an imposing appearance but compared to my black Marantz PM-15S2b, it’s about the same size. Personally, I love the look. When they say it’s built like a vault, this is the vault they refer to. The weight is imposing as well (55.12 lbs.) so take care when maneuvering it. You can turn it on with the remote or by pressing in the selector knob on the left. Turning it off is done by pressing and holding the same knob for 5 seconds, or by remote. The default volume setting when turned on is set at 10 so make sure to turn it down to 0 before playing anything unless your speakers are of low sensitivity. A well made manual is supplied but alas, it’s only in Chinese, but Alvin told me they’re making one in English.

Having 255 steps of attenuation gives one extraordinary range to get to exactly where you like to listen. You can go up 10 to 15 steps and not notice much of a change, at first, until something dynamic asserts itself or when you realize that in general, it’s now more impactful. Using the remote allows you to quickly go through the steps and adjust on the fly. I find this most handy and now use it to tailor the song or piece of music to my tastes.

As an integrated, it simply excels in it’s purpose. As verbose as I can tend to be, it leaves me speechless in describing it. It does nothing to detract. It does everything to commend. It’s incredibly fast and yet so utterly smooth. Musical presence is immediate but not etched, hyped or shrill. It’s light on it’s feet but can pounce and stomp when called for.

Liu, the amp’s designer, does not believe in exaggerated base and yet this amp goes lower, tighter and simply growls tone, details and ambience that I haven’t heard before. Lower registers of the piano left me slack jawed as I basked in the reverberations of the soundboard. The same goes for cello, guitar, percussion and massed strings. Imaging is the best I’ve heard in my system. Nothing wavers (unless done in post production) and separation is tops. With The Milk Carton Kids, the two of them finally are completely separated and at a greater distance apart than what I’ve been used to or thought they’d be. Small chamber music pieces have me scanning the soundstage as different pieces play distinctly in their own space. Back up vocals are distinct as well with no smearing. They may harmonize but they are clearly different.

Highs are fully extended, again, beyond what I’m accustomed to hearing. They can go on well into a piece and you can hear the decay even when some bigger play takes center stage. Bells and chimes can tickle like the real thing. And speaking of stage, it’s of one piece, the same no matter where you care to go. All the way left, right, up or down, even as far back as you care to look. The strength of the music lies everywhere you care to listen. The only limits are what was done in the recording.

It has no noise floor that I can detect. On Abdullah Ibrahim’s The Song Is My Story, he’s not up on stage, as usual, but I’m sitting next to him while he plays (I listen in the near field so that helps). The piano is the full width of the soundstage, steady as a rock, and the notes flow out around, up, and beneath me (great mike placement). Notes can and do come out of a completely black background unless the recording is done with less tricks and then you easily hear the venue, the room, the stage, the setting. And, I never thought I’d say this but FM now sounds pretty fantastic, considering it’s limits.

The sound is so pure that it’s reoriented the way I listen to music. I no longer listen analytically but for the sheer pleasure. It’s so rewarding and relaxing. Listening to favorites, I’ve noticed that some sound different enough for me to notice that there was some exaggeration or emphasis of certain parts of the frequency with my older set up. Whether it was the house sound that some say certain brands have or just the limits of the design I can’t rightly say. Maybe it’s all the extra circuitry added to accommodate all the extra features I have no use for. No matter. I’m content. Happy as a puppy with two pee pees.

Also, I have to give thanks to Alvin for his great customer service. He’s the most attentive distributor I’ve dealt with. His response to any question I had were immediate and thorough, as long as one is mindful of the time differences (just check your clock on your smartphone to coordinate appropriate time zones). 👍 He even followed up with shipping notices, delivery times, and any question I had with the unit’s operation or features, which reminds me, since it draws about 30-40 watts when on, make sure to leave it in standby when not is use. It can get very warm to kind of hot, but not hot enough for me to lay my hand on it for any length of time. If I had more space it wouldn’t be a concern (it cools off quickly). That leads me to believe that maybe since my JBL 4319 monitors are 92db, and that it doesn’t take much to make them sing, that the EX-M1, which is a Class A/B design, operates in Class A for the first several watts, which could account for the warmth of the unit along with the wonderful tonal density and texture. Someone with more know how can look into that.

All in all, it’s the best money I’ve spent and now I have no desire to upgrade to some PC based system. My CDs and SACDs sound fantastic, even the old ones along with the reissues. To think you’re getting a real taste of what the well heeled have been enjoying for a fraction of the price makes this a true bargain if there ever was one. Let me also add that I received no consideration from the manufacturer or distributor and these are my views and opinions.

All the best,
Nonoise

It depends on the recording, most recordings do not have very high dynamic range so I rarely find myself turning my Kinki past 12-14. In fact, for 3/4 of my listening I have the Kinki turned to 3. I may crank it to 35 at most. I might add, at that level I will be getting 103db spl peaks! I only do this when I REALLY want to rock out!! at this point my JBL 4367 bass gets so strong it shakes my whole room. Hehe 🙃 

Please note, I have my gain switched set to high.  For some reason I assumed this is better.

My dac has 2.5VRMS output and my speakers are 90db sensitive.. I usually listen to music around 10-15 during the day and 3-4 volume late at night..  For movies 15-25.  low gain enabled.  I agree there's no loss of detail or quality even at volume level 1 which is nice.  If you have super duper sensitive horn speakers you might not have enough fineness of control at low levels.. if you have a small room or listen at low levels like at night.. 
Dawid Grzyb of HiFi Knights used the EX-M1 with Boenicke W8's which are not easy to drive and it performed flawlessly.  In fact in a lot of ways he preferred it to his $16,000 hybrid Triology integrated.  So not really sure why all of the sudden concern about what it will and won't drive.  It's not like the average buyer is going to pair it with Apogee's or the like.  Bottom line is it's a great sounding $2200 bargain that will handle any speaker the average buyer can throw at it in an average sized room.  For the select few that feel the need to own the "difficult to drive" speakers like Apogee or the few others, there are plenty of five figure products designed for your needs. Gryphon, Pass, T+A, Audia Flight and others are out there waiting for you.  
@uncola  If there was a concern I had about the Kinki it would be the inability to play low level music at night as my dac puts out 3v and my speakers are 101db. But I just saw your post from back in Nov where one could request a preamp bypass option when ordering so that could be a good safety net for someone like me where I could use a passive preamp with the amp section of the Kinki if the gain of the integrated is too high for those situations at night.
Hi All

Just found this thread on the EX-M1 and wanted to share my setup. It previously consisted of a quad 405 copy using an Onkyo TX-NR809 as a pre-amp.  Speakers were Dali Concept 10 towers(91db) .  I purchased some replacement BIC speakers late last year RTR-EV15 (95db), as i felt the Dali's were under-powered with the Quad copy.  Fast forward to March 2019, i now have an EX-M1 that has replaced the Quad.  A Denafrips R2R Ares DAC which replaced a SMSL sanskrit proB and UPOCC Copper Litz XLRs joining the two.  The Onkyo is on movie duty only now.  I have gone back to the Dali speakers too as this amp has the power to feed 4 10" drivers, and spades in reserve.  Speaker cable are Van Damme Blue Series studio grade.  Awaiting the final replacement to the system...one of three last sets made, VAF Research DC-X63 towers which should arrive some time next week.

Review of the Kinki...as i purchased the amp and dac together the comparison to my previous gear is probably unfair, but what a change!  Nothing i can say that has not already been said it seems.  This is a fantastic amp, with power to waste.  The loudest i have had it is 130/255 and i have to be out of the room (with the Dali's btw).  The control this thing displays over the drivers is amazing.  The staging, pinpoint accuracy.  Depth etc etc...for its price it is an overachiever.  After three months on a production waiting list i am really keen to hear the VAF's next week.

The one issue i am having is noise.  I run a Bada LB-5500 conditioner.  I get noticeable noise at volumes greater than 30.  Once music is playing it is not an issue, but no static/noise is better than any.  Any ideas would be welcome?
