Following the update of our popular DA-151 Mk2, and with the same dedication to better performance, we released KECES DA-131 Mk2, to signify the difference and improvement it had compared to DA-131/DA-131.1.


KECES DA-131 Mk2 is a high performance DAC that will provide sound quality that will easily best CD Player and other sources at several times the price of KECES DA-131 Mk2, since most computer have SPDIF output, KECES DA-131 Mk2 is equally at home either on your computer desk or on your stereo rack.



How's KECES DA-131 Mk2 Sounds Like?:

1. Neutral Sound Signature: DA-131 Mk2 will sound great with pretty much any music, because is designed to sound natural and neutral, it introduce minimal coloration and allows the music to speak for itself, and that's how it should be.
2. Open Sound Stage: With an open and free sounding sound stage, music will not sound congested or overly exaggerated sound stage.
3. Precise Instrument Imaging: You can virtually feel the veil lifting, and literally hear each instrument and where they come from.
4. Highly Detailed Sound: You will hear all the details presented to you in a natural fashion, and you will be hearing a lot more of the details in your music that you have been missing.
5. Excellent Frequency Extension: You will hear even more treble and bass details, DA-131 Mk2 does this by showing you what you have been missing, not exagerrating what you already have.
6. Listenability: DA-131 Mk2 is designed to be easy to enjoy, even more important than ease of installation is the ease of enjoyment with non-fatiguing sound. After all, it would not be fun to listen to something that will fatigue you out quickly.

What other qualities does KECES DA-131 Mk2 have?:

1. Easy Installation: As with all SPDIF DACs, simply power on, plug in the digital and analog cables, and enjoy!
2. Full 24bit/192KHz Support: Unlike to most other DACs, DA-131 Mk2 can fully support 24bit/192KHz sample rate via SPDIF input, while most other DACs can only support up to 24bit/96KHz due to limitation of their SPDIF receiver.
3. Highly Refined Design: As with DA-151 Mk2, the circuit design of DA-131 Mk2 has been refined over the years for better sound and higher performance.
4. Quality Components: Using state-of-the-art National Semiconductor's LME49710 op amp, carefully designed supporting circuits, and a fully balanced analog power supply and fully balanced DC output circuit. All done in the never ending quest for better sound.
5. Precision Power Circuits: Independent digital and analog power supply, with independent winding and precision regulation circuits to provide high quality power to both digital and analog sections of the circuit.
6. Custom Low Noise Toroidal Transformer: Ultra low noise and efficient custom transformer is used in all KECES products, providing very clean power with high maximum output.
7. Compact & Stylish: Sturdy metal chassis with smoked acrylic top cover, it looks perfectly at home whether it is on your desk or on the stereo rack.
8. Performance Upgrade: Computer grade IEC power inlet is upgradeable to IeGO Audio Grade sockets at the time of order. For more dynamics, detail and warmth IeGO GU-R301 gold plated 99.99% pure copper IEC socket ($30USD) is a great upgrade. For even better dynamics, detail and an overall balanced and neutral tone, IeGO AG-R301 99.99% pure silver IEC socket ($90USD) would be the ultimate upgrade.

Neat and tight interior, circuit and component layout are all highly optimized.

IeGO IEC Socket upgrade information:


We provide two types of socket for upgrades, and both socket will enhance the detail and dynamics, but both enhance in a different way. (photo above shows AG-R301 socket, golden screw shown is replaced with better screws that comes with spring washer.)

GU-R301 Gold plated 99.99% pure copper IEC socket ($30USD) not only enhance the details and dynamics, it also makes it sound warm and smooth, the high quality processing done on GU-R301's gold plating process also makes it sound more refined and all without losing a bit of the details (Well, it actually enhances the details when compared to the original computer grade socket).  GU-R301 is warmer sounding than AG-R301, if you are looking for warmer sound signature with more flair, please choose GU-R301 over AG-R301.


AG-R301 99.99% pure silver IEC socket ($90USD) will enhance dynamics and detail even further than GU-R301, and as with very high quality silver, the sound is smooth, detailed and quite neutral.  It does not have the "silver harshness" normally associated with low grade silver or thinly plated silver cable and connectors, high quality silver sounds smooth, with proper thickness, very detailed and open.  AG-R301 is neutral sounding and more detailed with better dynamics than GU-R301, if you are looking for that, please choose AG-R301 over GU-R301.  Please note that while GU-R301 is warmer, AG-R301 is by no means cold, it is very neutral.
