The sound quality is excellent and free of any noises, easy to use and well built, but one thing I really didn't like was the maximum output volume in my Beyersdynamics headphones, it is significantly lower than my older Roland Edirol UA-25 sound card, that I cannot hear myself playing, therefore, almost unusable for me with headphones, which is very important :(
I am not sure if mine has a problem, or if they are all like that, but it's a big con for me, because I was actually hoping to get a higher output than my older Roland sound card, instead, I get significantly lower. And the sound quality is imo the same with the Roland, but yet, cleaner from any noise, which was to be expected.
So I am still using my Roland while the brand new Focusrite is now gathering dust. Personally, not happy with the output which is a deal breaker, so overall 3 stars for me :(
