Since I have changed the system about, I have these surplus to requirements. I doubt anyone here wants them, but I guess I’ll give it a go.
The Lynx is a digital only card with 16 inputs and outputs. These are AES/EBU. It’s a PCI card, so you need an old computer or certain very specific ones. There are copious cables, although some are untested. £50?
Up to 5 SMSL Sanskrit DACs, 10th anniversary edition, in black. Boxed, great condition. £70 each.
I do have an AES/EBU to SPDIF five way converter that I made up using resistors, which I’ll happily provide with the Lynx if you like.
