Leo J. ★★★★★ Oct 22, 2026

Finally, enough inputs to connect my DAC, phono stage, and streamer all at once to one system — that's 4 XLR and 2 RCA now. The setup was plug-and-play; no fiddling with software or drivers, which I really appreciated. For the price, it's a simple, solid solution for anyone running multiple balanced

I was a bit nervous about adding extra inputs, but the Ext90 makes it seamless—the additional two XLR inputs balanced perfectly with my setup.

Finally, I can use all four XLR inputs without constantly swapping cables. The build quality is solid and it paired perfectly with my preamp. It just works exactly as intended.
