A new standard in high-resolution audio, delivering high performance audio from a desktop component.

 

FEATURES

  • A compact (215mm width) digital-to-analog converter (DAC) with USB input
  • Compatible with 2.8MHz/5.6MHz DSD native playback and 32bit/192kHz high-resolution sound sources
  • Asynchronous transmission mode capability and 192kHz up-conversion option
  • Dual monaural design eliminates interference between the left and right channels. Built around twin BurrBrown PCM1795 DAC chips
  • Toroidal core power transformer
  • XLR balanced output
  • The USB DAC can be directly connected to a power amplifier or active speaker and the output level (XLR, RCA) can be set to fixed, adjustable or off.
  • By setting the XLR or RCA output level to “Off,” unnecessary circuits (other than those of the headphone amplifier) are isolated, enabling the sound quality of the headphone amplifier to be further enhanced.
  • Full metal housing provides both excellent vibration control and a classy look, in a compact size allowing convenient desktop positioning

 

Capable of 5.6MHz DSD native playback
The USB input facility allows DSD native playback which converts 5.6MHz DSD files directly into analog signals without needing first to convert it to PCM. It supports both the ASIO2.1 and DoP (DSD over PCM) conversion methods. Using the AI-301DA in conjunction with the TEAC HR Audio Player* high-resolution playback computer software application, anyone can easily explore the world of high-rez digital audio, including 5.6MHz DSD or 32bit/192 kHz PCM files, without having to grapple with complex settings etc. * TEAC HR Audio Player can be downloaded for free from the TEAC website.

 

Asynchronous mode-capable USB input
When receiving digital audio signals from a computer via USB cable, the unit can operate in asynchronous mode, controlling the timing of the input signal using the UD-301’s internal clock (which is identical to the one used in the UD-501). With asynchronous transmission over USB, signal compromising jitter is effectively eliminated, allowing digital audio signals to be transmitted in a pure, unadulterated state.

 

Up to 192kHz up-conversion option
When handling digital signals of 96kHz and less, users have the option to upconvert to double or quadruple the original signal sampling frequency. Even when playing back a 44.1kHz sound source (equivalent to CD sound quality) a smoother analog audio signal can be obtained in order to convert to a higher resolution digital signal. Naturally, this up-conversion facility can be switched in or out, according to the user’s preference.

 

Dual monaural design eliminates interference between the left and right channels
In order to process the audio signal from a high-resolution sound source in a purer state, we adopt a dual monaural circuit design whereby each of the left and right channels comprises its own single monaural circuit. This avoids mutual interference between the left and right channels and enables pure stereo playback.

 

High-performance BurrBrown PCM1795 digital-analog converter
The two internal BurrBrown 1795 digital-to-analog converter units each work on a single channel (left or right) for true dual monaural operation. They are capable of 32-bit processing and so have the capacity to process 5.6MHz DSD data in large quantities, making them indispensible for faithful and accurate playback of high-resolution sound sources.

 

MUSE operational amplifier enables highest quality analog signal processing
We use these in the analog circuit, they are a vital element in determining the final sound quality. They transform the electrical current output of the D/A converter into a voltage signal. We opted for a dual monaural configuration for the operational amplifiers, employing two MUSES8920 operational amplifier units, one on each of the left and right channels. These devices are made by New Japan Radio and are designed especially for hi-fi audio.

 

Even the headphone amplifiers used in the CCLC circuits are of dual monaural design
The 100mW + 100mW output (at 32 ohms load) headphone amplifier uses CCLC (Coupling Capacitor Less Circuit) technology. In conventional headphone output circuits, a capacitor is used for output-stage coupling, and so the sound is unavoidably colored. When the capacitor is combined with a high-pass filter this often results in phase lags, or low frequency level degradation. With CCLC the negative impact of capacitors on sound quality is eliminated, providing full low-frequency sound and a responsive headphone listening environment with great spatiality.

 

Doubles as a no-compromise, high-performance headphone amp
In addition to the dual monaural headphone circuits, there are options to switch off the XLR and RCA outputs on the rear panel. By cutting the power supply and isolating those circuits that are unrelated to the headphone output, the performance of the UD-301’s headphone output can be maximized. This feature also makes the headphone amp very easy to use as the volume control for the headphones is completely separate from the output mode (Fixed, Adjustable or Off) on the rear panel.

 

Toroidal core power transformer provides stable power flow
A high-efficiency toroidal core power transformer with low magnetic flux leakage is used to guarantee the stable operation of the twin left and right D/A converters that are so essential to the UD-301’s high-speed signal processing. This transformer provides a stable power supply even in situations where a sudden surge of power is required, such as when starting up at very high volume.

 

Well-engineered aluminum enclosure, compact proportions
Following on from our development of the 501 series concept (small high-performance audio components that can be fitted on a desktop) we decided, at the outset, that the 301 series would be an even more compact design. Now, the casework has been shrunken to just 215mm wide, allowing greater freedom in positioning the amplifier. External highlights include aluminum panels and a motor-driven volume knob with the tactile feel you’d expect from controls found in high end full-size hi-fi components. At the same time, the solid enclosure underpinned by the metal chassis, is impressively inert, minimizing the effects of vibration on the unit’s sound quality.

 

XLR balanced output
The UD-301 is equipped with an XLR balanced output that can be connected not only to other domestic hi-fi components but also to professional audio equipment. As a highly versatile, high-performance D-A converter, the UD-301 offers a high degree of interoperability with devices ranging from those used by discerning consumers all the way up to those used in the professional domain.

 

Connectable to a power amp in pre-amp mode
The XLR balanced output and RCA unbalanced outputs on the rear panel can both be set at Fixed, Adjustable or Off. Using the Adjustable setting, the UD-301 can be connected to a power amplifier to create a system with a separate pre amp and power amp or, alternatively, can be directly connected to an active speaker.

A price too good to be true, usually is.
If you’ve ever searched for a product on a shopping engine (such as Priceme/Pricespy) you may have asked yourself, “Why are some stores charging so much less than other stores?”

Our customers often share these stories with us, so we thought we would share a few with you, in hopes that you don’t fall prey to any of these unscrupulous sales tactics.

  • Goods may be grey market/parallel imported. They may state that the product includes the manufacturer warranty, but not tell you that the warranty is valid only in Europe, Japan, or South America, and NOT in NZ.
  • You may be asked to buy an expensive extended warranty. In many cases if you do not purchase the warranty, your purchase will be denied. (The product is now out of stock, your card does not go through, etc.)
  • Included parts may be sold to you separately. Some resellers will open boxes and charge extra for parts that are normally included by the manufacturer.
  • Hidden charges which don’t show up until your credit card statement arrives, these charges only show up when your credit card statement is sent to you.
  • When something goes wrong, faulty, late delivery, doesn’t matter how many times you try to email, they don’t get back.
  • There are so many scamming online sellers today, “buyer beware” protect yourself!

Concerned About Fraud?

The internet has become a more popular source for online shopping, regrettably we have seen more and more instances of fraud affecting online shoppers. Companies trading under many  different names, loading warranties and charging for them as extras when often they are included from the manufacturer. Parallel imports or personal imports where the NZ supplier refuses to repair when things go wrong is often alarming to the unsuspecting purchaser. Inflated freight charges, customs and GST at the border are often forgotten as a buyer is tempted by a lower price. Constantly we hear all these stories, once bitten it’s all to late looking for that refund or replacement. The stories are outrageous at times, customers from Trademe and ebay with no place to turn, time consuming and very frustrating….

So how do you protect yourself from online fraud?

  • Buy from an authorized reseller. If you are at all suspicious, contact the manufacturer directly and ask if a company is authorized to sell their products.
  • Make sure you get a company invoice with GST clearly marked.
  • Make sure you buy from someone who has a phone number and an address on their website, not a P.O.Box number
  • Read customer feedback, you can usually tell if it’s genuine or not.

We hope that you will become our next happy customer. And we promise to offer you superior service before, during and after your purchase.
