What cartridges are supported by the Alva Duo?

The Alva Duo supports Moving Magnet and Moving Coil cartridges.

What is the weight and dimensions of the Alva Duo?

Does the volume control the output of the line levels, as well as the headphone?

The volume control is for headphones only.

Does this have sufficient gain for a MC cartridge that produces 0.4mV output?

Not sure, it was used with different cartridges with varying outputs. Please check the specifications for compatibility.

Is there a way to turn off or bypass the headphone circuit or amp?

The headphone amp is only active when headphones are plugged in. Otherwise, the signal is amplified by the preamp stage and sent out through the outputs.

Do I need this if I am running my turntable through a Pioneer SX-1280?

The Pioneer SX-1280 has a built-in phono preamp. Check if the Phono 1 button is operational. If it is, you may not need the Alva Duo Phono Preamp.

Does it perform better than the integrated phono stage in the Cambridge Audio AXA35 amplifier?

It depends on personal perception and preferences. Some may notice a difference, especially when using it as a headphone amp. Dedicated phono stages are generally considered superior.

Do you need a step-up transformer to use this with a moving coil cartridge?

No, a step-up transformer is unnecessary. The Alva Duo can accommodate a low-output moving coil cartridge.

Do I need a receiver if I purchase this preamp for my turntable?

You will still need a receiver or amplifier to drive a pair of speakers. If your receiver has a built-in phono preamp, you may not need the Alva Duo Phono Preamp.

Do you have the grey or silver color?

The Alva Duo is only available in the color pictured.

Can this be used for a conference room polycom phone to boost the sound?
