Description
Power. Finesse. Extended frequency response. Speed. Delicacy. Control. Spaciousness. Precise imaging. Rhythm. Dynamics. Involvement. Musicality. The list goes on. Selecting only a few of these traits and asking any audio product to achieve them is quite a daunting task. Looking at the list and then listening to the 1108 Phono Preamplifier, it immediately becomes apparent that it can do all of them. With ease.
For quite a lot of people, vinyl or phono playback was the first time they had heard of Boulder. The degree to which our phono preamplifiers pushed the limits of analog performance forward was shocking to many and it drew quite a lot of attention. Decades later the 1108 is doing it all over again. With ease.
