An old USB receiver from TI - TAS1020B
From TI "This product is not recommended for new designs"
Why not use 24/192 Cypress USB receiver instead of the old TAS1020B?
Xilinx Spartan FPGA/DSP, Two gold crystal clocks over the Spartan.
Under Spartan there are three chips.
Left - AD1895: 192 kHZ Asynchronous Sample Rate Converter
Middle - Xilinx Flash for the Spartan FPGA chip
Right - AKM 4113 24/192 S/PDIF receiver
Going to the left of the circuit board
At the top - more old technology.
One AD1853 delta sigma 24/192 dac chip.
Under the dac chip there are two Lundahl LL1588 transformers

I thought the same thing. I thought the new "in" thing is higher sampling rates, and usb is the newest flavor of the month with 24/192. ?
Simply stunning to look at.
Rowland Aeris vs the new Berkeley audio Alpha 2 Reference DAC? Well this would be an interesting comparison for the devoted JRDG Aeris types who seem to really enjoy the JRDG DAC.
All things being equal in a system w/ JRDG amps, preamps and the like is it likely the Alpha 2 ref. Dac might be a tad more resolving, airy, spatial and detailed?
The power supply that comes w/ the Rowland is going to be hard to exceed in a single chassis unit like the Alpha 2 Ref. There are few JRDG dealers who also handle Berkeley Audio.
