KECES DA-151 Mk2 is the latest update to our popular line of USB DACs. Starting from the original USB DAC, to DA-151 and now DA-151 Mk2, each represents our constant dedication to improvement.


KECES DA-151 Mk2 is an audiophile grade source for your computer, it requires virtually no effort to install and provides sound quality far superior to other consumer grade sound card and USB sound devices.



How's KECES DA-151 Mk2 Sounds Like?:

1. Neutral Sound Signature: DA-151 Mk2 is designed to sound natural and neutral, it introduce minimal coloration and allows the music to speak for itself.
2. Open Sound Stage: 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. Lively Bass: Our new circuit further enhanced the bass extension, the bass that we were well known for is now even better.
6. Listenability: DA-151 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-151 Mk2 have?:

1. Easy Installation: Requires no driver installation, as long as you use Windows 2000/XP/Vista, MacOS X or recent release of Linux. Virtually no effort is required to enjoy high quality audio from your computer.
2. Highly Refined Design: Through its many evolutions, the circuit design of DA-151 Mk2 has been refined over the years for better sound and higher performance.
3. Quality Components: Using state-of-the-art National Semiconductor's LME49710 op amp, carefully designed supporting circuits, and a direct-coupled circuit that is rarely seen on USB DACs. All done in the quest for better sound.
4. Independent Power: Unlike other USB audio devices, DA-151 Mk2 does not use the noisy USB power; this vastly improves the background noise level, dynamics and sound stage details.
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.
