Another petite USB DAC which includes asynchronous USB interface, and up to 24/192 streaming. The Chinese built USBStreamer is available only online for $115. The company also offers OEM versions of the DAC for the DIY crowd.

AMR's iFi line starts dinky with the iDSD Nano, gets slightly larger with the iDAC line and then tops out (as far as size goes) with the new iFi iDSD Mini DAC.

Still not large by normal component standards, the Mini, which was shown in prototype form at the show, handles a wide range of digital sources including up to 24/384 PCM, DSD, Double DSD and DXD. Also included on the back is a full range of input jacks, with a volume control and headphone jack on the front.

Inside, there is aptX Bluetooth streaming, 4 Burr Brown DACs, and 4 filters set by the user. Retail price will be under $1,000 and it should arrive sometime this quarter according to the distributor, Avatar Acoustics.

Also new in the AMR (Abbingdon Music Research) room is the DP-777 DAC/Preamp SE (special edition) which features a "Quad Core Digital Engine", NOS GE 5670 Tubes and "Ultra Premium" coupling capacitors. The DAC handles PCM inputs up to 24/192 and pricing is still to be determined, but it will be somewhere north of $5k.

More than a decade ago, Data Conversion Systems, aka dCS, released the Elgar Plus DAC, Purcell upsampler, and Verdi SACD/CD transport, for a total price of $34,000. In 2009 came the Scarlatti—a stack of four components for $80,000, also available individually (see my August 2009 review). The latest variation on the English company's theme are the four Vivaldi components, launched at the end of 2012 for a total price of $108,496.
