The 'perfect' setup is three great singers on stage with you!

Even IF a VH unit came out that was indistinguishable from real singers (and a few are getting close!), you STILL have the problem that they can ONLY sing when you do! Try to find much in the way of BV's that do that!

That's probably my biggest issue with VH... Even if they are PERFECT, they are still wrong! And they are still a LONG way from perfect!
