Looking for a headphone amplifier/USB DAC that is developed and backed by an audio design expertise? If yes, Teac UD-503 is the right option for you to consider. With its dual-monaural structure that is just exactly the same with what is used in UD-501, this is really promising as a USB DAC/Headphone Amplifier. The Teac UD–503 has also been supported by two of the most trusted AK4490 DAC chips. These have so far been classified as the newest models manufactured by the Asahi Kasei Microdevices Corporation. Actually, there are still more features that are included to ensure guaranteed satisfaction of users.
Build Quality and High Performance
Excellently-built to meet even the most meticulous buyers out there, the Teac UD-503 has once been on the list of top choices available. This is because of the fact that its analog output circuits are classified and chosen to be the best. They serve as the keystone for good audio quality. There are also the so-called TEAC-HCLD circuits which have been the output buffer amps.
Prior to operation, it was classified as something of high performance. This is because it is completely-balanced and it simply utilizes parallel-unbalanced and XLR output, particularly when using unequal RCA output.
The DAC section, for instance, has simply exceeded the demands and expectations of customers and users. Even its headphone amp is known for its discrete structure. In the front part of the panel, there are 2 TRS phone jacks that promise such a strong driving force.
The Teac UD-503 is an extraordinary product because of its high and precise volume control. This control feature enables two-hundred fifty-six setting steps including a remote control. This newest generation of headphone amplifier/USB DAC is recognized as the premier desktop audio to captivate your attention for its quality built and high performance.
The Sound of Teac UD-503
The Teac UD-503 boasts its sound that is widely known as one of its promising and strong points. With its good and easy listening sound and the vocals sound that are such a lush and rich, the more that you will love and appreciate this headphone amplifier.
Nothing has been mentioned about its low frequency, mid frequency, and high frequency. But, it is great because of the fact that it is ready to greet you with a full-bodied and round sound. Embodying an easy and good listening quality, it can simply be just ready in grabbing your attention.
Such a deep solidity can be heard from the first words uttered by a singer, like Kate Bush. There is simply enough insight to how she communicates the emotional outpouring of the lyrics. Thus, this is something that is not provided by other headphone amplifiers.
Soundstage and Separation
Buy the Teac UD-503 that exudes an even deeper soundstage, tighter bass, and darker background. This is even greater than other similar products because it does not bring any form of harshness. This, therefore, makes it an ideal option to consider.
When the Teac UD-503 is connected via USB, it is expected that it does not pair well with a computer clock that is noisy and stable. It just mainly supports USB transfer mode and it allows it to be in control of the DSD and PCM signals. It actually pairs up with its clock that is generated by a built-in and precise crystal oscillator.
The pairing or synchronization is also possible because of the ten megahertz external master clock input. By pairing up with a clock that comes with a higher precision, you will be able to enjoy an improvement in audio quality and changes in tone quality. Search for Teac UD-503 for sale and notice just how great it is in a pairing.
