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

Thanks, Alvin, for asking, and tell him I don’t understand a word but he has my respect.

Since ole nonoise was dead on about the amp, I just bought and started using some Darwin Ascension II interconnects. First, like Alvin, Tony Bender is a very fine person to deal with, and though I’ll have more to say later, the sound really compliments the ex M1. Damn, nonoise, you really are getting me in deeper.

Anyone else out there with this amp?
Hi guys, I decided to participate in the discussion here since there wasn’t much activity about the Kinki amp in our local forum. I’ve had the ex-m1 for about 2 weeks now, and I agree with everything you guys have said. Fast but smooth, highly detailed, transparent, superb bass control and transients.

However, I want to ask if any of the other owners find it lacking juice reserve. I’m playing in a relatively small dedicated room, 13’ by 10’. Regular listening volume on most albums doesn’t exceed 30, but I sometimes crank it to 50+ when I want to play slightly louder. That said, there are certain tracks or albums that require much more juice for it to sound properly dynamic and loud. A couple of these tracks are Hans Theessink - Mississippi, and Hugh Masekela - Stimela (The Coal Train) from The Dali CD 1. On said tracks, I have actually pumped up the volume to the max 255, without it sounding unbearably loud. But then again I’m on the ’low gain’ setting, connect via rca interconnects. Understand from Alvin that ’high gain’ is only +4db.

Though I’m not a person who listens at a high volume often (at night my listening volume is 10), it is fun to crank it up occasionally. I don’t think my speakers are particularly hard to drive, as they rate in at 88dm/8ohms (only dipping to 6.4ohms). But this worries me a little, as I have never ever in my life, cranked up an amp to max volume. My previous Job INTegrated, though rated lower in power, felt like it had a lot more juice reserve than the Kinki ex-m1.

Wonder if the other owners can chip in and share their experiences.
That's been the opposite of my experience..  I usually listen between 10-15 on low gain..  but I do listen very close to speakers...  But it seems to have as much power as my Odyssey kismet 200 watt monoblocks which have like 180000 uf in filter capacitance and 650va transformers each..  speakers are 86db 8ohm bookshelves..  would using high gain help you keep the volume control in a more useful range?
@martine51,
I'd never steer you wrong. 👍 Not after the Kinki recommendation. I feel that what works for me can be of benefit to others.

@benlzy,
I don't have the newer version with the gain switch but even then, I've only had to turn it up to 80-90 when playing opera, to get close to the full effect of a live performance, but then, my speakers are 92db. 

I did, however, go up to 200 with my older Clearwave Duet 6 monitors that are 85db and I could have went higher. With both speakers, it all depended on the recording, which can vary a lot. 

All the best,
Nonoise
@uncola 
The volume increment from 0-30 is quite substantial, but the gain from 30-255 I feel it probably less than 10-30. At the 100+ range, you can crank up 10-20 notches without even perceiving an increase in volume. I'm listening to them in a rather near field setting too (small room), about 6' away from the spks.

@nonoise 
Yea I guess it's all about the recording. I will switch to high gain then on those albums. 99% of the time I won't have to go into the triple digit range, but it's just startling to me as I've never max-ed out an amp before. There was no distortion even at max volume though, which accounts for something.
