Audio Aero Capitole MKII- Direct into Amp?

Just wondering who among you may have experience with running the Audio Aero Capitole MKII directly to your amp, using the internal analog volume control instead of using a preamp....

How is it?

If you've compared it to a preamp connection, can you share your thoughts?

Does the volume control include a l/r balance adjustment?

Thanks in advance for your thoughts!
