The Paradisea Plus USB DAC is a bargain highly recommended. I think he will find thanks to those listeners, the relaxed, natural, warm, smooth power, fluid and emotional music from their digital wish. Remember, you first had sex? The Paradisea + is better than that. Ok, maybe not good, but it’s really good, and perhaps the musical equivalent of a special evening with someone special.
CARAT-TOPAZ (Signature) is new Cara-Topaz, which is also an international export-only model was known. This combination product variety RUBY2 such as USB phones, flat head, the chip digital and analog OP Amps DAC device and configuration hexadance Sapphire, which the upper class of the CARAT series and USD is an insulator, which was used on T2-CARAT , the SDC. About how the pieces of the world’s leading luxury hi-fi audio, he retained the traditional style of the audio. Finally, it was tested and compared with matching range of high-end audio products and audio style. You will experience a sophisticated, elegant and reasonably easily by CARAT-TOPAZ Sig (signature).
The TOPAZ style audio is our largest model, which is an extremely affordable and high-quality USB DAC and headphone amplifier and the series version of the third style audio JEWEL .. A custom PCB design is very dense and filled with high quality components, including: OSCON and WIMA caps, 1.0ppm TCXO clock and Vishay-Dale resistors. Isolate, besides the use of top-shelf parts, the designers also separated each section of the unit, input, digital conversion, power switch and analog sections from each other to ensure a very low noise floor.
Simaudio MOON added Resolution USB interface for “Perfect Bit” Performance 24-bit/192kHz USB with data on their 650D and 750D DAC / CD Transports.
This interface is a digital input card using the popular XMOS XS1 microprocessor as an input receiver made??, so totally asynchronous data communication. MOON 650D and 750D is all from this point will be equipped with the USB interface with high resolution. For equipment manufactured before November 2011, a simple to in-the-field upgrades by a dealer or distributor MOON, which involves a simple exchange of PCBs that no firmware update or welds required to be carried out – The new board uses all existing mounting hardware and connectors.
The project PCM2704 USB DAC sound card is fully functional for the PC sound card. The main advantage of using PCM2704 PCM2702 is against the construction much easier. As seen from the diagram that he in 5V and 3.3V voltage regulator, HID interface (MUTE, VOL +, VOL-), S / PDIF output. Joined see The circuit can be directly from the USB port power. Next advantage is that the DAC output can directly drive 32 Ohm headphones, but the performance is only 12mW. For full details please refer to the PCM2704 datasheet.
The program is very simple. It is almost a copy of the chart sheet. You can see the core IC PCM2704 (U1), the crystal with documents (X1, C1, C2, R1), the connection to the USB port (USB port, R2, R3, R4, L1), a large number of blocking capacitors for all voltages (C3, C4, C5, C6, C7, C8), head of the S / PDIF output (J1), HID-header (J2), the output of the filter (R5, C11, R6, C12, R7, R8), coupling capacitors (C9, C10) and the output 3.5 mm jack connector (J3).
