The Interchange Ethernet interface is my best digital audio solution ever. I have designed 6 generations of USB interfaces and I have to say, this is better. It supports DLNA/UPnP.
It comprises two small chassis and has S/PDIF, AES/EBU, SE I2S and HDMI differential I2s outputs. The second chassis is a special version of the Dynamo LPS with Hynes regulation:
The front panel displays 6 PCM sample-rates, from 44.1 to 192. The hardware is capable of outputting native DSD64 from the I2S outputs, but has not been tested.
I don't usually do this, but here are the guts:
As you can see, it's modular in design, with separate dual turboclock module and separate Ethernet module with an onboard SBC (single-board computer). Turboclock uses custom Crystek oscillators. Each part of the circuit has it's own Hynes-technology regulator. 6-7 Hynes-technology regulators total, depending on options. Options include:
- OTL mod to eliminate S/PDIF galavanic isolation and improve jitter - $150
- Hynes-technology regulator for the I2S outputs - $350
- Standard external silver BNC cable - $275
- Reference external silver BNC cable - $499
I highly recommend using one of my external BNC coax cables because the risetimes are so fast on the S/PDIF output.
The Dynamo is an ultra-fast responding linear power supply.
Superb SQ can be achieved with Linn Kinsky controlling Minimserver, both freeware for Windows, Mac and Linux. In my system, this SQ beats Jriver, Amarra and Roon. Unbelievable imaging and liveness. Very 3-D, holographic.
If you want to stream Tidal, you can use BubbleUPnP with Linn Kazoo.
Here is the jitter distribution measurement:
This shows how often the ideal time period is deviated from.
About 10psec standard deviation both sides of the distribution, measured at the end of the S/PDIF cable across the 75 ohm termination. This is a realistic jitter measurement of the source only, not dependent on the DAC.
I listened recently to about 100 remastered Beatles tracks and I have never heard them like this before. Like McCartney and Lennon are in the room with me.
The Interchange is a DLNA/UPnP device. Compatible with Jriver, Linn Kinsky, Linn Kazoo, Lumin, Twonky, Minimserver, BubbleUPnP and others. No Roon.
