I'm very familiar with the original VAC Avatar, which has four things going for it: 1) Switchable between triode/ultralinear, 2) great el34 tube sound for voice/midrange, 3) it's a VAC, which means great sound and good investment at used prices, 4) not really any advances in tube sound since it was made, and VAC still supports them.
The subsequent Avatar models might be better in some ways, but I've never heard them, and you lose 1) and 2) above.
