NX3 - TOPPING. Sound Blaster X-Fi Surround 5.1 Pro - Sound Blaster - Creative Labs (United States) Quantization Noise Killed The Cat - USB DAC. “I haven’t heard a DAC even triple its price that comes close.” - HiFi Pig If you like music and have it stored or streamed on a computer, a USB DAC will sound a lot better than the analog output of your computer.
A USB DAC is plugged into your computer with a USB cable and into your stereo system with an analog (RCA/Phono) cable. If you are fond of open source projects, this DAC in particular is something for you. The AB-1.2 USB DAC from QNKTC does three different things at the same time: It is a good sounding USB DAC 100% ready to use.Although you don't have to, it allows you to experiment with audio hardware. The AB-1.2 lets you play high-resolution audio (up to 24 bits at 192kHz) from Windows, Linux and OS X computers. This is what people say about its sound character: A few technical details: Regardless of your type of computer read the Windows Driver Installation Guide. The AB-1.2 is sold with the help of PayPal. Here is what the press writes about the QNKTC AB-1.2: AB-1.2 Back A: No.
USB-I2S module RC5. Audio DAC with AD1865. Menu Introduction Circuit AD1865 is considered like best 18bit stereo audio DAC ever. It is not recommended for new constructions and probably is not manufactured now. However it is still available on EBay. Circuit has SNR 110dB and THD+N 0.003%. Circuit description Supplying need two separated windings on power transformer, because I used positive voltage regulator for negative supply branch. DAC doesn't have I2S input, which is usual. Data are in sequence shifted in to the internal shift register of dac first for one channel and after switch of LRCK for second channel. For analog output I used current output and passive I/V converter with resistors R1 and R2. 18bit version schematics diagram schematics of 18 bit version in Eagle 5 format 24bit version schematics diagram schematics of 24 bit version in Eagle 5 format Assembling We assemble PCB from smaller parts to bigger. 18bit version component view 24bit version component view 18bit version PCB PCB is single sided without wire junctions.

What is the O2 and ODAC? The O2 is a headphone amplifier created by NwAvGuy. The O2s purpose is to offer an affordable yet superb listening experience designed for the most transparent reproduction of sound. From a computer through a USB cable, the digital sound signal is send to the ODAC which converts it to an analogue signal for the O2 amplifier. The novice audio DIYers build description This is a build description of a O2 with ODAC build made by a novice audio DIYer. Being a novice audio DIYer with no prior experience soldering or building electronics, a lot of time was invested in collecting useful resources, doing things methodically and going at it slow.
