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,

It’s the 8A fuse. I believe Alvin told me it was 10A but both the active fuse and the spare one in the holder are both 8A. Also, it’s the smaller 5X20mm fuse, and not the 6.3X30mm fuse.

Expect a bit of a roller coaster ride as it breaks in due to the Rhodium plating but once it’s settled in, all will be fine. If you listen a lot, it should take no more than a couple of weeks but I’ve heard of a longer break in period.

All the best,
Nonoise
Nonoise, what size is the fuse as two are available?  (Dimensions)

10 or 8 amps?
Yes, I saw that and commented on how well the recording sounded even through your iPhone. I think you'd have to spend a bit to up the quality or have the chops to get into the recording before posting but what you did more than conveys the sound character of your gear. But then, I have something similar and know what to listen for. 😄

All the best,
Nonoise

I posted this in my own thread but thought maybe you guys who haven’t seen might appreciate it. Apparently the recording I did using my phone mic is of good quality?

Its my JBL 4367 paired with the Kinki.
Yup. It’s the same vendor I bought from before. And it’s UL, PSE and SEMKO approved. If I had known the correct rating, I would have tried it earlier, tweaker that I am. 😄

All the best,

Just for sh!ts & grins I went and ordered a AHP fuse to try out in my EX-M1. I was surprised to see that the fuse that comes with it is rated at 8A and not the 10A I was told, but no real bother. Substituting the AHP fuse for the stock one (a ceramic bodied fuse with what looks like normal end caps and no logo) left me a bit wanting.

Intelligibility (enunciation, etc.) was up a bit with what seemed a sharper focus but at the expense of weight or gravitas. Lower mids and bass were emasculated. 

Feeling a bit let down, I was going to put the stock fuse back in when I remembered I had some other 8A fuses from other ventures. Remembering how solid the PADIS fuse sounded in my Marantz integrated and that it had about 2 months on it already, I put that in and it sounds, so far, like a killer pairing. 

It's like the music put on about 10-15 lbs of muscle but lost not one bit of it's fleet-footedness. Extension, both ways, remains with some serious weighting of the music and all the exquisite highs and detail that originally are there, are simply enhanced. Sound stage is not affected one bit.

What used to sound like a stark, studio like presentation (a good thing) is now an in-the-room rendering. If you have the time and like to fiddle and tweak, getting a PADIS fuse is a cheap and easy fix. They're about $25 not including shipping and you can get them from eBay. Well worth it.

Access is easy as the fuse resides in the Furutech IEC inlet so you don't have to open the EX-M1 up.

I'd like to add that just listening to the radio with the enhanced nature of the PADIS, sent me back to my youth for a moment, bringing up memories of listening to my dad or uncle's radio, with that almost analog like sound of fulsomeness and warmth. sitting in the dark, and looking at the glow of the gear.

All the best,
Nonoise


I've just listed my Kinki EX-M1 for sale if anyone is interested in saving a few hundred dollars.
ocd hifi guy's recent video showing the kinki powering the magnepan .7 speakers with zero distortion even with volume at 100% has me considering them.. I was kind of long term planning on something like spatial m3 turbo s but the magnepan are also interesting.. I already have a sealed sub to use with them.


Wow, I wish I’d known this.  I wonder why this thread is nearly dead. My Kinki is still wowing me with sound stage, detail and apparent zero distortion!
You have to ask for a custom preamp bypass rca input when you order.. I think it adds $100 to cost?  Very reasonable
Can you run the Kinki as a power amp? In other words can you attach a preamp to it?
uncola,

"Time to put the top back on..."
You get a pass here, but on another thread you would be called a non-audiophile and what not for having a cover on your amplifier.

Isn't it time to wake that thread up again?
Nothing like the stink of 🐈💩 in a thread. Use the box, Kitty. 🙀
yup!  Time to put the top back on and carry my old amp to the giant pile of unused amps in my closet :P

Here's a sexy pic of the amp with no top on.  btw opening it is tricky, ask for help if you need to for some reason.  There's nothing inside to adjust though, no trimpots for bias current or things like that.

Hey guys I finally replaced the preamp/volume control board in my kinki.  They sent me a replacement board at my request.  Just wanted to report that it took less than an hour with me being very careful and taking lots of pics to remember where everything was plugged in before starting work.

Now my channel balance is perfect between lvls 16-32. It must have been one of the relays like you guys guessed.

Listening to the Bohemian Rhapsody soundtrack in flac and the foot stomps in We Will Rock You are transporting me to a stadium :)
Just upgraded my power cord as suggested in the Kinki manual. I am quite apprehensive regarding claims made about power cords but in this case I have to eat a bit of crow. I love the Kinki but found it slightly anemic in drive. Quite a sophisticated amp but a little light. Right out of the box the Verastarr Grand Illusion PC added heft and everything seemed to develop a little more dimension. Voodoo witchcraft maybe but this stage brew seems to cast a spell on my Kinki. 

Nice video you got there. 👍
I might have to play catch up. 🤔

The vocals came across nicely, despite your iPhone 7. 😄
The vocals have that "in the studio quality".
Clean and present, but not in your face.

All the best,
Nonoise
Right now there's a video up over on Youtube by OCD HiFi Guy with the Kinki, a Jay's Audio CDT and a COS DAC with a pair of Maggie .7s and he loves what he hears. Apparently, the Kinki can make anything sound better. 👍

All the best,
Nonoise
I'm late to the show!
Somehow I missed this review when it was written.
Very nice job, nonoise :-)
I can see how this integrated would make your JBL 4319's sing!
I was in a lottery once, and I did “win.”  I almost went to Canada. 🙀
Kinki is sounding great each day of break-in. I have about 150 hrs on it so far.
Take heart. You live in a beautiful country, and have a wonderful new amp. Pour a glass of Mission Hill, and chill. 😀
I had a lot going on since I got off work today, was in a really foul mood and not in the mood for music at all. I did attempt to try. Suffice to say I was very surprised how good the Kinki is. It's even better then I could have imagined. I Will save more thoughtful impressions tomorrow when I'm feeling less of a grouch. 
Nice review @mboldda1 ! The EX-M1 certainly feels like it's gonna be my last amp for now.. I ain't got no deep pockets like Bill Gates! The monoblocks do seem interesting though. But that's another box, another pre, and a few more sets of cables. Best let my wallet recover.
i’m use to a more forward sound as a lot of tube gear will do it and as I was weened on usher speakers yes indeed a more forward presentation.

i’m digging on analysis plus cables and cerious technologies cables.
Mighty fine précis, bold one. I don need no stinkin’ power cord, and my sound stage varies with the recording but is generally somewhat forward, though not much, of my KEF R900 speakers (on borrowed time).  I agree the cables and interconnects matter, and Darwin interconnects are a great match. 
Thanks @moboldda1 for the thumbnail sketch. Can't wait to read your  full review over on Alvin's site (vinshineaudio.com). 

The Kinki allows you to put more than a toe into the high end waters. More like waist deep when you factor in the cost. 👍

All the best,
Nonoise
Open a thread here?  One line conclusion?

i sure wish d2 would check in, but I remember my first day. 👍
well, I just emailed the completed ex-m1 review to Alvin.
couldn't hold this back.
 

Final Thoughts


The Kinki ex-m1 is one of the best sounding integrated amps I have heard. While it sometimes comes up short against the big boys but given it's price it's a no nonsense choice for those of us that don't have the deep pockets of Bill Gates.


The highs, mids and bass put the Kinki on a level that a lot of audiophiles would think of it as their last amp.

The sound stage is located just behind the front of the speakers but does not take away from it's depth.

The height and width of sound stage is also there. The Kinki has pinpoint imaging.

The looks are a little spartan but wouldn't you trade some looks for better sound and less cost.


Please use a good power cord, I use Cullen Cables, it does make a difference. The amp lets you hear the differences in interconnects and isolation devices.

All in all I can without hesitation recommend to anyone looking in this price range and above. As always try to audition stereo equipment at home in your system. It's probably hard to listen to an ex-m1 without purchasing it, but I doubt you would be returning it.


China is on it's way, some people moan when they hear “made in china” , but remember there was a time when we said that about Japan.



You wont sleep for three days....

Note that when you plug it in, it immediately goes into standby!

Make ALL connections BEFORE you plug it in.

If not...🙀👀🔥☄️⚡️🌶🎱🏑🤼‍♂️🎭🌋🚽
