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,

Hey everyone. I figured out why my soundstage was creeping over to the right. It was not that CD from Japan after all. All of my music was starting that rightward march bit by bit and it was driving me crazy.

It turns out that every time I pulled that heavy maple media stand out to get at the cabling (think pivot), when I put it back I neglected to notice that it was now an inch or so to the left. Having that big, reflective OLED TV in the middle acted in a negative way as never before. 

In total, with all the pivots, it was about half a foot to the left of where it should have been and that was all it took to throw off the soundstage. With my Marantz, it was never that critical but with the Kinki, it needs to  be right. 

Another face palm moment brought to you by the exacting nature of he Kinki EX-M1.

On a positive note, there is now a maturing of the sound to compliment the other positive aspects (sound staging, separation, detail, etc.) It's like it's going through puberty into adolescence. Fulsome and robust, even with the small stuff. There's an ease to the gait of the music that's now almost animal like (natural and unforced).

I like. 👍

All the best,

How is this possible?  Voices and instruments seem to be separating and increasingly fixed in space. The sound, overall, can only be described as pure. You can hear strings vibrate. Is it truly changing?  Hmm. 
Oh, no way in Hell it is a sympathetic vibration. If you use one channel, the sound comes right out the speaker, not somewhere in the room. Using both channels, it is a lovely stereo ripping sound. 

I have not changed my opinions and KEF hasn’t, either, though we resolved our differences and I agreed to move on. The whole DIY thing left a really bad taste in my mouth, too. 
Yes, same crap, with the same vocals. So, from McIntosh, to Rotel, to Kinki, and all new interconnects and cables from Cardas and Transparent. 

I’m truly disgusted. I’ve got to get my arthritic ass in my car and travel 30 miles to hear some Vandersteens. These things are out of here as soon as I can find a buyer, and if I can’t, I’m hiring two guys to take them to goodwill. They sound great until that crap manifests, and then it is horrible. 
maritime51, just curious, are your KEF r900's still acting up with your new integrated?
Day two is progressing. My Rotel 1590 combo is fully broken in, but I don’t think the Kinki is, so weigh this with my comments. The Rotel seems warmer, or more musical, but the EX has far more detail. The rotel seems denser or more full, but the Kinki produces a quasi 3d soundstage. The Kinki produces bass that is fully controlled and fast, though the Rotel isn’t far behind. 

The Kinki is clearly superior in every way at low volume settings. Go figure. 

If this thing improves markedly, it will easily overtake the Rotel combo in every way, and mind you, the RB 1590 is a high current amp, rated at no less than 350 Watts per channel into 8 ohms. 

Ive rearranged my speakers to compensate for the lack of a balance control. 

My preliminary conclusion is that $2300 for this amp is a joke, but I don’t agree with the Six Moons dude that it is a “universal” amp since some, but not me, must have all the controls and then some. 


Thanks. It is a very trivial matter. Dim is just right !  A lot of thought went into this amps design. 
yes, only dim or bright.  kinki says the reason for not having an off is you would not know the power is on.
Day two begins. It’s 4:30 am. Say, does lighting have only two settings, dim and bright?  If so, I’d suggest more steps. I love the audible volume clicks!
Thanks maritine51. It's not easy to wholeheartedly endorse something without that nagging little voice in the back of your head saying, "maybe it's just you...."  😉

All the best,
Nonoise
Your review and comments have been very accurate. Thanks for them. 👍🏻
Yes, it does continue to impress. It seems to get more 3D like. Not really holographic but the players seem more real than when I first started listening.

It's easy to take things for granted and think it won't get any better until you put on a CD that you tried before and just go, "wait a minute....it didn't sound that good before". Moments like that.

I did have a bit of a heart attack tonight as that one channel that perplexed me and led me to move my speaker further out turned out to be a faulty interconnect. It was so gradual that I chocked it up to room anomalies and it was when I started swapping out cables, I lost one channel completely. 

At first I thought it was the Kinki since I started with the speaker cables and then my old monitors and it all pointed to the Kinki, being the same channel. Then, with my heart beat up, I swapped out ICs and that's where the fault lie. 

Whew....too much drama for one night.

All the best,

Now 15 hours in lots of changes. Everything has denser tone and things have become a little more relaxed. Space has developed a sense of 3D. This is a nice sounding amp. 300 hrs of break in.... 295 to go. 
Nonoise did yours keep evolving past 150.
I don’t think the controls are needed but some folks may want them. Too bad about the battery. 
Yeah i read forums often 😀

We stopped shipping battery in the remote control as we got fine, a costly overlooked of battery declaration. $100 fine is too much for a small CR2032. The declaration paper work is too much too to get this tiny battery shipped. 

It is a long debate or should or should not have balance/tone/eq control. To each his own 🤝


Just keep in mind there are no controls of any kind, so if you need balance controls or whatever, ....


Considering the Accuphase is 3.5 times the price of the Kinki, that's high praise, indeed. 👍
Hi guys just got hold of a kinki amp for demo.All I can say is it's a fantastic amp.Currently using a Accuphase E370 and mind you it easily on par with the Japanese Sgd$7.8k amp.Go buy it if you are looking to upgrade .
Man, if you close your eyes, with some cd’s you’d swear it is live. 🙊
Nice to see that you're hanging around Alvin. It's amazing that I'm still learning all that there is to this gem. After fiddling with speaker placement, all my CDs now sound much more coherent and have more body.

At first I was overwhelmed with the detail and sound staging but that was only the beginning. 😀

All the best,
Nonoise
Good God, Alvin, it really is nice!  I’m getting more and more detail, and some vocalists are in near 3d. 

I suggest including a battery for the remote, or a slip of paper with the specs. 

Alvin, you ARE the MAN. 👌
I see that Kinki makes a lot of men happy! 😈
Thanks for your support! Enjoy the music.

Many thanks. 

Best,
Alvin 
Nah, She Who Must Be Obeyed....

Man, as this thing warms up it is merciless on details and the bass is so fast it is unreal. 
I think mblodda1 is correct but I think it's probably the cables being the culprit concerning your highs. I found mine to be a bit hot with only one singer (who has tremendous range and power for a folksy bluegrass singer) and trying out a new set of SCs completely cured it (it turns out it’s simply the SPLs that singer is so easily capable of).

I’m learning more and more about details and room interaction. I’ve never had it on a scale as I do now, with the Kinki. My usual speaker placement never excited room boundaries like the Kinki does.

The wave launch is so accurate and powerful that what I needed to do is move my right speaker out 3" to the right to balance out the staging (now it’s perfect). I’ve never had to do that before. Equal speaker distance from center was always the norm with anything I’ve had before.

As long as I point the speakers directly at my ears, and with the right speaker moved out, the soundstage takes on a new dimension with staging about a yard out to either side of the speakers, increased depth, and no sound actually coming from the speakers, unless it’s an old issue like Chet Baker’s The Italian Sessions.

With that one, he is hard right, straight out of the speaker but the bass player is way off to my immediate right (literally the 3:00 position) which put him 8’ out into the room and 4’ over to my right (leaning forward moved the position of the player accordingly). That’s when the Kinki showed me the limits of my room as no other piece of gear has.

When you get an incredibly accurate amplifier that doesn’t molest the signal, all manner of heck can happen (good and bad). 😄

All the best,
Nonoise


Good point, as the amp is silver. It sticks out in my black system like a diamond in a jackass’s behind!  👀
Rotel seems to have better soundstage, but I can’t bias toward the left to compensate for the room. I’m delighted so far. 
i think they might be raising the price in the future, glad i got in at the start.
I’m hearing details never heard with a McIntosh mc202, or rotel rc/rb 1520. Nice. 👀😘
i found the top a little recessed, could be the different speakers we have.
you're kinkified!!
He, he, he......  😄😄😄
Another notch on the Kinki belt. (let the puns fly)

As for the battery, its' a 3V circular type. You have to remove 4 screws on the back to get to it. It should last a long time. I just got a 4 pack for the foreseeable future.

Enjoy and bask in the sound. I don't think you're going anywhere this Labor Day weekend.

All the best,
Nonoise
Gone through the beer and dare not leave...just opened a lovely Col Solare. Christ, I hope I don’t pass out. 🙀💸
put the beer on ice.
forgot to mention, the isoacoustics iso-pucks work well with the kinki.  the iso-pucks come two to a box and they are $60 per box.  you will need four  iso-pucks (two boxes) for the kinki.
