Hi! Just got myself a Cary Audio SLI 80 Signature! Gonna use it to drive my livingroom speakers (Rega R7) and with headphones, of course. Posting a picture - it's a real beauty Anybody else out there? edit: Some headphone facts from Cary: It's headphone socket is directly coupled to the power amplifier: The headphone out of the SLI-80 due go through the whole tube circuit and are tapped off of the transformer outputs. After the transformers the signal passes through the headphone switch and then a couple of resistors, then to the headphone jack. The output impedance of the headphone out on the SLI-80 is 8 or 11 ohms depending on who you ask.
