Momentum pre - using 2nd output for headphone amp
 

The Momentum pre has 2 sets of balanced outputs. According to Bill McKiegan at d’Agostino, they are both active all the time. I’m wondering if I can use the 2nd pair for a headphone amp. The headphone amp (Woo WA6) has no balanced inputs, so I’d have to convert from XLR to RCA at the pre or headphone end. I would only run either the headphone amp or power amp, never both at the same time. Does anyone see any issues with this setup? Will having both outputs connected, one to a balanced device and one not, change output impedance?

Tony - I asked the same thing before I got my Momentum pre.......they called D'agostino to confirm and they said that there would be no problems using the second set of outputs like that....I was asking in case I wanted to use the output for a subwoofer. They said the same thing, both are active and should be no problem.

Cool, thanks Buck.

On second thought, it occurs to me the output is volume controlled, so that may present a wrinkle for a headphone amp.

I would turn the Woo volume knob to the 2 or 3 o’clock which should approximate unity gain....then use the pre to control volume.

Tony - Whatever you decide, and if your not aware, a pair of adapters are included with the Momentum PreAmp - Ed
