Foreword:

There has been a lack of desktop speakers for use with computers, and it is also intended to be a USB amplifier. Just recently a good friend hand has a good quality USB decoding amplifier SONY UDA-1 out, the Internet looked under can be used as a USB amplifier, but also with a headset to enlarge, be more complete function. For those of me who don’t ask for a lot, it’s the most important thing to do, and it’s decisive. Aunt Zhang read it carefully. There was no relevant sunbathing. Then I came to deceive the gold coin.

Jingdong's current price is still not expensive, less than 3K can win, compared with the listed price, the purchase is still more cost-effective.

Taking into account the power amplifier thrust is relatively small, there is no bullet to start with the original SS-HA3 speakers, after comprehensive comparison finally chose the innovative XM7 this passive speaker. Innovation this group of boxes is now not expensive, before the double eleven, discounted down 739, and now the price is basically the same.

Appearance & Usage:

First on a desktop family portrait. Since it is not a new product out of the box, all the packaging is now no longer what it is, and the opening of the box will be omitted directly on the map. This equipment purchase is mainly to use XM7 this box output, occasionally use the two headphones on the hand to use SONY ZX700 + SONY MDR-1A, the headset itself is not high impedance, relatively speaking, are still relatively good push.

This amp has silver and black, friends out of the silver, but also just like this color. The design of Dafa is still awesome, with a high degree of integration and a relatively simple appearance. The front end has a 6.3 headphone output connector and a USB data input. Occupy most of the space is the input source selection, for me, the input is basically computer access, so it is the use of the rear USB port input, which is the display of USB REAR, the advantage is that the front USB input support audio The format specification will be higher. The far right is the volume control knob and DSEE function indicator light.

SONY's LOGO is a sign of faith, and the work is still pretty good. The touch is very good, and the switch button is very comfortable when pressed. There is a function that is quite interesting. There is no sound for a long time and the amplifier will automatically shut down. This design is still very user-friendly.

HIRES gold standard, belief plus mark å“Ÿ. Sony's small gold standard, now more and more manufacturers began to support, Dafa is always at the forefront of audio, as Dafa must be like.

The volume knob feels good and the damping sense is just right. After using it for a while, you can see the dust on it. The DSEE function is turned on, and it feels better when listening to MP3. In lossless format, opening DSEE is invalid.

The front panel warning light is more, if it is HIRES audio source, the second row will light the corresponding lamp after reaching the standard. I usually have more lossless CD sound quality, HIRES's audio source is still relatively small, so the second row of lights rarely have time to light.

The front USB port can be used as a data access port. I mainly use the computer output, considering that the rear input desktop will be more beautiful, and at the same time it will be better for audio support, and the basic front is useless. This interface can be closed using plugs. Dafa is also considered to be very inconvenient, considering the frequency of use is not high.

Front ear amplifier 6.3MM output, I use the headset are 3.5MM, so need to use the adapter. Plug feel good, details of the Dafa interface work is also considered good.

On the back is the support of some of the interface, in fact, is still very complete, in addition to does not support balanced interface, nothing short of board. With such a small thrust, there is no need for balance. But for me, with so many interfaces, most estimates have no chance to use.

This is a remote control. It's really hot and it's not a good touch. After all, spending so much money, the final remote control can not take snacks. Dafa's remote control is indeed too tricky. Many functions must be operated through this remote control. For example, DSEE is turned on, such as mute switch. Of course, this guy also supports volume adjustment.

Put an overall picture, the amplifier is still very small, and the 24-inch display compared to speakers, not large. The desktop still looks more coordinated. Please ignore the messy wire and plan to purchase a millet storage box. There is no waiting in the near future.

XM7 this box is still very heavy, the Internet looked for a long time, compared to a relatively thick choice of the final innovation of this XM7 (after all, such a small thrust of the box is really not easy to sell). So far, this box is still satisfied with . There are two kinds of yellow and black, considering the final choice of black. Some of the time when the desktop comparison wheel, plus the position is not how to adjust (move the box and the desktop really toss), how do not take the box, and finally left this picture. XM7 work is still very good , The woody feeling is strong and the things are thick.

Listening:

UDA-1+XM7: Using the combination of boxes, it is felt that UDA-1 can basically release the quality of the box. The sense of low frequency is not enough, but the dive depth is not bad. The level of vocal restoration is very good and the degree of separation is reasonable. When the dynamic range of the symphony is relatively large, the headphone discriminating degree is not high, and the combination is very easy to distinguish. Sound field positioning is more accurate. As an introductory desktop system, I think it's enough. The treble section is also quite good, there is no particular erratic feeling.

UDA-1+MDR-1A: The sound is somewhat dry and not round. When diving at low frequencies, it is obviously not enough for the dive. The separation of the vocals is not enough, and the feeling of the instruments and the vocals is mixed. Being alone as an amp is not a good choice.

to sum up:

UDA-1 is indeed a good choice if it is used in conjunction with computers and is not willing to make too much of a toss. Decoding, power amplifier, and amp are all available. But the thrust is not really big. Of course, the most important thing is that I am very satisfied.
