I received and used Objective 2 for one week. It is a very good production. It has very low noise (can't heard), very low distortion, flat frequency response. I used it for Sennheiser HD 600. It is very good match.
Needed some extra power for my AKG 612 Pro's and this little thing delivered. Just buy this thing, you'll never regret it.
