I took a long time before I decided to buy the Fluid SRI-2 interface as it was at the top end of what I wanted to spend and there are many choices out there. I am very pleased that this was my final choice.
I am using it to feed a pair of Yamaha HS7's and a pair of PreSonus Eris E3.5's. It was the fact that the SRI-2 had dual outputs that ultimately swung my decision to buy this product as a lot of its rivals only have single outputs.
The SRI-2 has a very solid feel, It looks great and oozes quality. It has very firmly planted itself on my studio desk and doesn't move unless I lift it up and change its position. The control knobs are all super smooth and have a surface that is easy to grip and operate, especially the large volume control knob. The output is very smooth and clear.
One slight criticism is that although the main USB cable is supplied, there is no USB 2.0 Type A/Micro cable included, which you will need to get the Mic and Line inputs to operate on the Phantom +48v.
The only glitch I had was on the initial setup, but it might be unique to me and my system (Windows 10). I connected as advised and then went to the Fluidaudio website and downloaded the updated driver. Somehow in the installation my computer lost an Audio.dll file, and my computer wouldn't recognize the SRI-2 on my system.
In the end the only way out was to carry out a system restore and then download and install the updated driver before re-connecting the SRI-2 back into the system. After that it all worked fine, but it was a bit frustrating to have to do that.
There is also a hardware update available on the Fluidaudio website but Windows Defender warned that it might be an unsafe download so I didn't risk it. I will message Fluid Audio to see why this might be.
Overall I would say that you get a great product for the price and would certainly recommend it.
