BLOCK AUDIO - Line and Power Black SE
Dual Mono balanced preamplifier and headphone amplifier.
One of the finest preamps in the world, this is a RARE opportunity to enjoy an exquisite preamp for a fraction of the original price.
This is a one owner unit, traded in on a CH Precision L10 preamp. Unless you are going to go with CH Precision this is as good as it gets sonically.
Comes in the original flight case, comes with factory supplied apple remote
The unit is perfect EXCEPT for two scratches on the battery power supply which were cause during removal from the rack. They are visible in the pictures.
Unit would be available for demonstration by appointment in the Liquid HiFi showroom.
Potential in home demonstration available assuming client is willing to cover associated costs.
