ExaDevices: The exa U2I [$430] is an async USB/I?S interface with DSD64/128 support.

 

More 32/384 -The exa U2I [$430] is an async USB/I?S interface with DSD64/128 support. "Asynchronous operation is achieved with a fast FPGA control core, 256kB fifo buffer and proprietary ASIO driver. Galvanic isolation of the FPGA's I?S output and USB ground is via giant magnetoresistive digital isolators. Barrier capacitance between board circuits and I?S outputs is 17pF. The I?S output is powered by the external DAC's power supply and fully independent from USB power supplied to the board.

 

"Two precision quartz oscillators allow very accurate clocking with minimum jitter for the 44.1kHz and 48kHz sample rate families. Two voltage regulators with low-pass filters provide low-noise power to the FPGA core and quartz oscillators. This further minimizes jitter and noise. A custom designed ASIO driver provides automatic sampling rate switching and bit-perfect data transfer. The USB socket is a mini type."

 

 

exaU2I USB to I2S Interface Overview

Multichannel asynchronous USB to I2S audio interface delivering 384 kHz 32bit low-jitter bit-perfect performance

 

exaU2I USB to I2S Interface is the missing link between a PC and the I2S input of your DAC. exaDevices USB to I2S Interface is designed for use in high-end DIY audio projects aiming to achieve sonic performance that rivals traditional audiophile grade gear.

 

exaU2I is the first affordable device on the market that makes it possible to stream multichannel 384 kHz and 352.8 kHz DXD audio in full 32 bit resolution from a PC to a DAC with professional mastering quality.

 

Asynchronous operation is achieved by using fast FPGA control core, 256 kB FIFO memory buffer and proprietary ASIO driver.

 

Galvanic isolation of the I2S output from the FPGA core and the USB ground virtually eliminates jitter and common noise originated by the PC. Isolation is achieved by using Giant Magnetoresistive (GMR) Digital Isolators. The barrier capacitance between the board circuits and the I2S outputs is 17 pF.

 

The I2S output is powered by the external DAC power supply and it is completely independent from the USB power supplied to the board.

 

Two precision quartz oscillators allow very accurate clocking with minimum jitter for the 44.1 kHz and 48 kHz sample rate families.

 

Two voltage regulators with low-pass filters provide low-noise power to the FPGA core and the two precision quartz oscillators. This further minimizes jitter and noise.

 

Custom designed ASIO driver provides automatic sampling rate switching and bit-perfect data transfer. The exaU2I USB ASIO driver operates in asynchronous mode and it is completely independent from the Windows sound system

NuForce DAC-100 | MSRP $1095

 

 

NuForce DAC-100 is a class-leading digital-to-analog converter (supporting USB and S/PDIF) and headphone amplifier designed for consumers seeking a level of performance typically found in the finest audiophile equipment.

The DAC-100 accepts up to four digital input sources and features a precision digital volume control, a high-power headphone amplifier section with extremely low distortion, a high-resolution analog RCA output stage, and a convenient wireless remote.

The DAC-100 incorporates several NuForce innovations:

Low Jitter

The DAC-100’s digital input stage operates in an asynchronous mode independent of any timing errors associated with the incoming digital audio stream. The input stage synchronizes the data to an internally referenced timing signal generated by an exceptionally stable circuit. The re-clocking circuit’s accuracy is such that any negative timing errors (jitter) are reduced to near theoretical limits. Read about Jitter FAQ

Powerful Headphone Amp

The DAC-100's headphone amp delivers enough power to drive most headphones with absolute authority. It provides a full 500-milliwatts Single-Ended Class "A" power, held by many audiophiles to be a headphone amp’s purest form of circuit topology.

Precision Volume Control

A digital 32-bit volume control offers precise channel tracking. Unlike more common digital volume controls operating at 24 or 16-bits, the 32-bit dynamic range of the DAC-100's volume control avoids any loss of low-level resolution.

Transparent Preamp

The analog preamp stage is a minimalist design offering a signal path that approaches a straight-wire-with-gain level of performance. Combined with top quality parts and a full 2.0Vrms signal level at the RCA outputs, the preamp section of the DAC-100 ensures that only the purest of analog music signals will ever be presented to your preamplifier.

No Up-sampling

A 24-bit, 192kHz DAC stage accurately converts digital audio data back to an analog signal at its native sampling rate. No up-sampling or other questionable data manipulation is ever employed.

Note: For Async USB Audio, please refer to the Async USB Audio FAQ and Setup Guide.
