What is the best Vox combo?

The 'best' Vox combo is a matter of taste and opinion, but the most recognisable, most iconic model is the AC30 Top-Boost. This is available in numerous versions, from the Chinese made AC30C2 to the British made 60th Anniversary AC30 Handwired. Both sound fantastic.

Do Vox make combos for home use?

Yes, Vox actually make quite a number of smaller, house-friendly practice amps. Have a closer look at the Vox Pathfinder, the VXII Modelling amp and the VT20X combo.
