Gallo Reference 3 SA Owners

The "volume controls" work more as tone controls, not for loudness. The SA fills still fills in the lower octaves on your Gallo 3.x's with the so called volume controls set at flat or zero. The manual explains it much better than I can.

Volume control on SA amp is pretty much personal preference. The manual even indicates that you may want to set the volume control at different levels for different types of music. Mine are set at zero at all times. Spectron amp.

Verbatim beginning at the bottom of page 8..."The volume controls on the SA operate much like a bass tone control on a receiver, except that they're far more precise and allow independent adjustments for each channel. Listening to your favorite albums, you can easily set the tonal balance and the subjective amount of bass exactly to your liking. You could even have multiple settings such as 'flat' for classical and 'fat' for pop, rock, reggae and hip-hop. Why not? It's as easy as turning up the two gain controls by a predetermined amount, so it still sounds coherent, but a little bit stronger in the low bass than is perfectly flat".
