I own the Vac 160i for about 6 months now. It is a fast and tight amp. A powerful tube integrated amp. Much more like a solid state IMHO.
I have another set of tube amp, the legendary BAT VK60 with ARC ls17 preamp. They just sound sweeeeeet and warm. sweeter and warmer than sigma but not as powerful as the Sigma.
If you have sensitive high db speakers like Tannoy, avantgarde, you can try BAT VK60 amp if you like speakers like magico s1, wilson or revel, VAC amp is a better choice.
