  Your looking at the original Giant Killer Preamplifier from Sonic Frontiers! This one is in Mint condition and has been completely serviced and upgraded last week by Avatar Engineering ($525) to Above the Signature series issue! ( See Photo's). The upgrades included new larger capacitance audio grade electrolytic capacitors with a polypropylene film bypass capacitor in the power supply. New higher quality small electrolytic caps on main board. The major upgrades were done to the inferior original film capacitors which were replaced with: Mundorf film and oil, teflon, polystyrene and polypropylene boutique film and foil capacitors! Key resistors were upgraded with .1% Caddock TF( best in the world) and Kiwame resistors. The Opamp was also upgraded and all the switches and potentiometers were cleaned and lubricated. Lastly the Tube is a NOS Telefunken with approx. 100 hrs. on it!  We have this Gem playing now in our reference system and it is Truly holding its own compared to the $12,000 preamp which is usually in the system! Very impressive, soundstage, imaging, bass and resolution! You will be hard pressed to find a one owner, seldom used SFL-1 in this condition cosmetically and functionally! Original packing and box.
