AUDIO RESEARCH VS VTL

As you're only comparing two brands, then one can only say which is better. (Best applies with a minimum of three.)

That said, there are at least half a dozen brands of tube amplification better than the two named.  And that's a modest estimate.

Both are okay arc tends to sound more solid state like with vtl really depends on the model

We would recomend zesto unbreakable sound and incredibile customer service also very reliable

Were placed a set of 40k cj art amplifier with a 20j set of zesto Eros the zestos sounded nearly as good for half the price

No companies that just started up and may be out of business in 2 years. ARC, VTL, VAC have been around a long time. 

Zesto Audio started up in 2010, so not a start up. Have you listened to either VTL or ARC?

Fly by night. lol
