ETI Research RCA Chassis Connectors
The ETI Research RCA Chassis Connectors offer extremely low resistance and capacitance due to their construction. Unlike many types which utilise a “wrap around” design the FS and FR construction is more like a needle on a stylus as only a fine point makes contact on the signal pin of an RCA connector. This design offers much more transparency as the mass is greatly reduced.
Silver or Gold
Polymer
The contact point on the FR-TC07 is 1100 Copper with a gold-plated Tellurium Copper connection blade. The Return and Connection Blade is Gold Plated Tellurium Copper which is needed for the durability of years of reliability.
The contact point on the FS-08 is solid Silver with a silver-plated Tellurium Copper connection Blade. The Return and Connection Blade is Silver Plated Tellurium Copper which is needed for the durability of years of reliability.
Instead of just a solid return body which adds capacitance, both models have a polymer body that not only adds to the transparency but also stops any contact with the metal housing it is installed to. The Nut is made from Brass which is great to help reduce any vibration and EMI/RF.
This type of manufacturing adds cost due to the amount of process needed. However if accurate sound quality is required then it is worth your investment into the FR-TC07 and FS-08
