Bifrost是Schiit最新的入门DAC, 非常好
Bifrost is the world's most affordable fully upgradable DAC, featuring 32-bit D/A conversion, a fully discrete analog section, and a sophisticated bit-perfect clock management system, together with one of the most advanced asynchronous USB 2.0 input sections available, as well as SPDIF coaxial and optical inputs, all with 24/192 capability.
Now, if you're new to this whole DAC game, the only thing you might have gotten out of that sentence was "affordable" and "upgradable." That's fine. We want Bifrost to be affordable, because you shouldn't have to take out a second mortgage to get fantastic sound, and it's upgradable, because, well...times change.
Fully Upgradable: The Future-Proof DAC
Worried about rapidly-changing USB input technology? Concerned about future advances in D/A conversion? Bifrost's modular design uses separate, snap-in USB Input and DAC/Analog cards. When USB technology changes, you can simply drop in a new, better USB Input Card. When meaningful upgrades to D/A converters come out, you can snap in a new DAC/Analog Card. The result? A virtually future-proof DAC that won't end up in the dumpster.
AKM4399 D/A Converter and Discrete Analog Section
Even without considering upgradability, Bifrost offers incredible value. Consider its AKM4399 32 bit D/A converter, used in DACs costing many times more than Bifrost. Also consider that our analog section is a fully discrete, low noise JFET design—the only op-amp in the box is a DC servo—just like multi-thousand-dollar "statement" DACs.
Advanced Bitperfect Clock Management
The ugly truth about most DACs in this price range is that they sacrifice every single one of your original music samples to get their magic "192kHz" spec. Every input is routed through a sample rate converter and upsampled to 24/192. Bifrost dispenses with the sample rate converter and uses a sophisticated master clock management system to deliver bit-perfect data to the DAC, preserving all the original music samples--whether it's 16/44.1 or 24/192.
USB 2.0, 24/192, Async, Completely Buzzword Compliant
Have high-res music? No problem. Bifrost offers a full range of inputs: Coaxial and optical SPDIF, as well as USB. Bifrost's USB is one of the most advanced implementations available today, featuring a high-speed USB 2.0 interface (not 1.1) and asynchronous data transfer to 24/192, based on the C-Media CM6631 USB receiver. No drivers are required for Macs, and Windows drivers will be downloadable from this site for Windows 7, Vista, and XP.
