Single ended designs are renowned for their transparency and clarity and this amp is no exception. Some 300B designs have been criticised for rolled-off bass, however the 300B valve performs well on bass and requires high quality output transformers. This Quicksilver design features very high performance output transformers.

These amplifiers are wired point to point without using circuit boards.

These monoblocks are ideally matched to high efficiency speakers, however they perform surprisingly well with less efficient designs.
