I am so happy with the Focusrite ISA Two. I really did my home work before buying this preamp. It can really get frustrating trying to find the right preamp at a great price and the Focusrite exceeded my expectations. It doesn't leave anything behind and has a really natural sound with just a pinch of sweetness. I am looking at adding another to my rig. Sounds great on everything. After owning it I have to say it's a no brainer.
