For sale: Sonnet Technologies Echo Express Pro Thunderbolt expansion chassis for PCIe cards. These are great for Universal Audio UAD-2 PCIe DSP accelerator cards (this one was previously running two Octo cards) and other similar devices. Sale includes the expansion chassis and IEC power cable only (not pictured). Requires a Thunderbolt 1 cable for operation.

This chassis is in perfect working order and decent cosmetic condition. One of the rear screws was broken and has been replaced. The bottom feet were missing, so we installed replacements. Despite being a first-generation Thunderbolt device, there is still more than enough bandwidth to run a pair of UAD-2 accelerators without issue. IYKYK.
