Headphone amp connections

[UFObuster]

Just bought a Grado headphone amp and need a little advice on hook-up to my RSP-1068.
Excluding CD and Tuner audio-input, I have 4 other audio "inputs": TV, 2xDVD, and PC (for MP3).

Is the Zone 2 output to the Grado the best option to hear all 6 audio inputs? Is the Zone 2 output the same quality? Are there headphone options that I need to know more about? Should I use the 3 (only) audio analog outputs from the 1068 and get along without one of my input devices? Will the "tape" output work for a headphone amp? I'm looking for a superior sound quality to my 'cans' so it's important that I know how to get the best from my sources. I'd also like the best output with the least trouble in set-up and operation.

Thanks,
Roger

For most preamps, Tape output is the best way to feed a headphone amp. Tape output is fixed at the full level of the input signal. Zone 2 output is variable with the volume control on the 1068, not what you want when your headphone amp has its own volume control. (Even if the Zone 2 output is set to "fixed", the signal is still passing through a bunch of circuitry of the 1068, whereas the Tape output gets the signal straight off of relays.)

However, with the 1068, both the Tape and Zone 2 outputs only pass analog audio. They do not receive digitally processed audio. If your source components are connected through optical or coax digital, you'll need to also connect them to the 1068 with analog RCA cables to hear any output through Tape or Zone 2. In my opinion, this is a design flaw of the 1068, but it greatly simplifies the unit's relay switching for analog output.
