Critic Reviews

Fluid Audio SRI-2

soundonsound.com

Fluid Audio's SRI-2 is a stylishly designed USB interface and monitor controller that delivers clean audio quality and great ergonomics at an attractive price. Its robust build and thoughtful features, like dual monitor outputs and a smooth control knob, cater well to desktop setups. However, the interface lacks a spec sheet, and some users may find the single headphone output limiting during collaborative sessions. While it doesn't offer expandability via ADAT, the SRI-2 competently fulfills its basic role without any significant drawbacks. Overall, it presents a professional look and feel that belies its modest pricing, making it a solid choice for budding audio engineers.

Probably nothing better for this price

In this price range it's very hard to find something this good. The preamp has no discernible noise until ~80% gain. The controls are very simple and effective; and the dual monitor outputs can come in very handy. The construction of this thing is off the charts; it's very solid and built like a tank, and the big knob that controls the monitors is great and very satisfying. The instant reading levels also are very useful. The thing with this little piece of equipment is that Fluid Audio is not a very known audio interface brand (their forté has always been studio monitors [which can explain why this interface has also monitor control functions]), so, for this price range, buyers tend to go towards buying the Audient Evo 4 or even the Scarlet Focusrite 2i2, both great interfaces, but I sincerely think the SRI-2 is superior.
