Now a brand absorbed into Anthem AV, Sonic Frontiers started as a high-end parts distributor in 1987 : Wima, Vishay, WBT, Gold Aero, Cardas, ALPS et al.
The transition from parts supplier to manufacturer happened in the 1987, first as kits (SFM-75) then as factory built - with much success ahead.
The SFT-1 was SF's first CD player, built to exacting standards for stable readout and very low jitter replay : 16.9344MHz clock placed right next to the Philips CDM-12.4 drive and over-beefy and regulated power-supplies with two potted toroidal transformers.
The top cover is damped with a sorbothane sheet ; three silicone rings soften vibrations of the mechanism.
Outputs comprise S/PDIF (Sony/Philips Digital Interface) in s-e coaxial and BNC, balanced AES/EBU and Hewlett Packard glass optical ST.
UltraAnalog chips work on the servos alongwith an Intel 8082. Laser control is done by two Philips TDA-7073 and a Philips SAA-7345.
As measured by UnltraAnalog's jitter analyzer, the internal jitter of the SFT-1 is of only 2 picoseconds between 100Hz and 40Khz, increasing to 10 picoseconds once at the digital outputs.
The only problem (today) is the center of the SFT-1 : the CDM-12.4 mechanism. If greatly integrated and very cheap to produce, this drive proved however far less reliable than the "old" CDM-0, -1 and -4... and was recently even difficult to find.
The SFT-1 was later-on also available in anodized black panel (front) and natural silver (mainframe).
I for one will nevertheless always be amazed at such decisions : a 50$ plasticky drive as center of a 2000$ component... And while the warranty was of five years for the parts and labor on the unit, said warranty was shrunk to a mere ONE year for the Philips drive itself !
Case in point.
