I tried high quality sound by connecting a digital amplifier with a USB DAC attached to a magazine "Digifire" appendix to a PC

A digital amplifier with a DAC that connects with a handheld PC and USB, outputs sound as analog to a speaker and enjoy high-quality sound reproduction is a PC audio special magazine "Digifing(Tax included 2980 yen) ", so I decided to make a simple stereo set to purchase and actually play music on PC.

◆ Photo review

Digifai of the issue with appendix is ​​like this.

It is appealing power amplifier with USB DAC greatly with the character of "special appendix!".

It's about this thickness as seen from the side.

The contents box is as follows.


Only the contents of the amp body and metal screws.

It is about this size when it puts on the hand of an adult man.

Looking from directly above it is like this.

Audio output method is only speaker cable, so be careful as headphones etc can not be connected.

Power supply and volume control etc are not installed.

It has an input terminal compatible with USB B male

The chip up mounted on the board is as follows.

The condenser is like this.

It is possible to fasten a metal screw to the board and make it into a leg.

It will be like this when you put the legs on. Even if you have only a Phillips screwdriver, it will be over in about a minute.

Turning it over looks like this.

◆ Tied with a PC · speaker

Just connect the USB plug to connect with the PC OK.

Connect the speaker cable by inserting the tip of the cable into the hole as follows.

Speaker cables for analog output can be purchased at home electronics mass retailers and so on. In addition, we used "Audio Technica AT 567S / 3.0"I bought it at a nearby Yodobashi camera at 210 yen for 1 meter.

Connect to the speaker side as well. Some speakers use speaker cables only for LR connection, and some use audio cables for input, such caution is necessary because such models can not be connected with this amp.

Setting complete.

◆ I actually tried to ring

Please check the following movie to see how you are actually playing music.
