I am selling this for a friend who recently purchased it brand new making the move to streaming audio, he thought he needed it then discovered he did not. He sent this brand new unit to me to try out, knowing I am big into PC audio. This new unit was plugged into my system for apprx 1 week and had a signal run through for approximately 100 hours, so this unit is practically new. I broke the seal on the plastic bag the unit was in.
MSRP of this is $1995 US, you can have this unit for $1100 that includes paypal fees and free shipping to you in the continental USA. This unit is the 120V version, has original box, manual, CD driver disc (not needed as windows 10 now has USB drivers) and generic power cord.
I also have an almost new 1.5 M Transparent Premium 110 ohm AES/EBU digital link that can be purchased MSRP is $975, Add $600 to the above price ($1700 for both) and paypal fees and shipping will be covered. I do not have the original Box this Cable came in. Cable on its own (no alpha) asking $675 which includes PP fees and free US Continental Shipping
From the Manufacture
The Alpha USB is an asynchronous High Speed USB to digital audio interface that extracts the highest possible audio quality from computer audio sources.
The Alpha USB features a High Speed USB 2.0 input data connection and switch selected audio output signal type – either coaxial SPDIF using a BNC connector or balanced AES using an XLR connector. Sampling rates up to 192 kHz and word lengths up to 24 bit are supported.
Great care was taken in the design of the Alpha USB to isolate the noisy computer/USB environment from the digital audio output. The USB receiver and processing are powered by the computer, while the output master clocks and line drivers are powered by a separate isolated linear power supply.
Two key factors combine to achieve the excellent audio performance of the Alpha USB – the unprecedented degree of electrical isolation between the USB input connection and the audio output and the very low noise/low jitter performance of the individually tested audio output master clocks.
The Alpha USB is designed to work with both Apple Macintosh and Windows PC computers. Apple Macintosh computers using Snow Leopard or later operating systems have a High Speed USB Audio Driver that interfaces directly with the Alpha USB. It is not necessary to install a special driver. Windows 10 also has USB drivers.
