Kinki Studio EX-M1 200wpc Integrated Amplifier

Another question I’m curious about regarding this amp concerns gain. Sensitivity is specified as follows:

Input Sensitivity: 2.25Vrms - 3.6Vrms

I’m guessing that 2.25 volts is for the unbalanced inputs, and 3.6 volts is for the balanced input, as I don’t see any means of varying the sensitivity in the internal or external photos. Given the 215 watt 8 ohm power rating those sensitivities can be calculated to correspond to gains of approximately 25 db and 21 db respectively. Which seem like very low numbers for an integrated amp, and perhaps too low to be optimal with some combinations of vinyl sources and low efficiency speakers.

Yet the review contains the following statement:

Who actually needs 200 watts with 26dB of voltage gain in just the line stage followed by another x 20 amplification factor in the power stage? Very few. Because the EX-M1 hits its torque already in first gear, that number is mainly for bragging rights, peace of mind and yes, the rare customer who really does own that boat-anchor load to tap such power and gain.

That would mean a total gain of 52 db, which in contrast to the calculated numbers would be very high for an integrated amp. And probably too high to be optimal with some combinations of digital sources and high efficiency speakers.

Just wondering how to reconcile this apparent discrepancy, while having some concern that all of these numbers may be a bit extreme in one direction or the other.

Hey David,

Yes, the comparison will be in Ezra's system because he has the current reference T+A model. 

Also, wanted to share that Mike Powell is a great gentlemen who is a true craftsman who builds beautiful audio gear.  I believe that Alvin made a wise choice to create a relationship with Mike to be the US repair station, in the case something needs to be fixed after purchasing the item.  This completely eliminates any anxiety about having to ship all the way back to Singapore, along with having someone with Mike's skill and level of excellence take care of any problem. Alvin has great taste in the brands he sells, both on quality/performance, and the ratio of performance to cost should have other companies concerned, if customers use their ears and not what something costs.   

Can this integrated amp be purchased domestically or only through Vinshine? Not sure .....I know Vinshine Audio has a great reputation, just wondering if a US option is available.  Most likely not as that is one reason the price is so attractive.  I must admit this looks to be a fine piece of audio gear. Most interested in it.  

Hi Grannyring , yes a very valid concern, so I am here as the USA counterpart to Alvin at Vinshine. I plan to keep at least one piece of the top sellers in stock here. This means a USA distro center for the Vinshine products. (I am known in the audio scene and am honest to a fault) If it happens to be a time when we are waiting for inventory, you could prepay a deposit with me here in USA, and then I would ship a few days later after it was received. Service issues are handled here in Atlanta and so far have been very few. only 2 to be exact. each of them were just sent a new unit and we kept the repair. Most likely that will not happen all the time, but lets say we fix yours and send back.. no more than 72 hours in my hands and it ships right back. I can also provide free professional consultation for my clients insofar as rig/room setup is concerned. Sometimes I feel really bad when I realize how long and how much money some of us have spent chasing the sound that we all know exists when honestly all it takes is a pro to spend a little time on the phone with you to spot issues immediately. Prime example feeding the biwire loudspeaker using full range cables and jumpers and feeding the bass posts and jumping to the highs. If you have them wired this way I’ll offer a free instant upgrade/ Go run the cables to the top/high binding posts and jump them down. There are so many little things. My purpose in life is to get the most Audiophiles I can into the "magic" zone. I can do this with a $3500 complete rig (used price) up to the six figures, world class level. I can provide your results over the phone. The fact that I’m working with Alvin and Vinshine simply expands my toolbox to create those magic rigs for more people. I am very picky about quality. In fact you can hear the Vinshine product being compared to others sometimes much more expensive on my Youtube channel called "OCD Hi-Fi Guy". I play into the charachter lots of us have in our head about this crazy hobby. subscribe there for updates on the latest demo and shootout videos. You can actually hear the difference in DACS , it was surprising to me that it was so clear. I’ll be doing the Kinki Studio amp Demo in about a weeks time.

Glad to be of service ! Happy Listening

P.S. Thanks for the kind words Terry !

@teajay Should be a fun day at Ezra’s place! In addition to the integrated amp comparison, I’m looking forward to your take on how Ezra’s Tekton Ulfberth BEs are settling into his system. Can you share that side of the system 'experience' over on the DI thread?
