Sonic Frontiers SFL-1 [Expired]


no longer for sale

The Sonic Frontiers SF -1 is a brilliant and highly acclaimed valve line stage preamplifier. Please note that this is a line stage unit and does not have a phono stage. The unit uses one (1) 12AT7A valve. These are readily available and very inexpensive. The “signature” sound of the SF-1 can therefore be easily customised to personal audio preference by simply experimenting with different types of valves. The unit is currently fitted with a close to new JJ valve. The unit has five line inputs. There are also two output stages for either bi-amping or the connection of ancillary equipment such as a sub-woofer.
