Is the Audio Ref-6SE worth 7K more than the BAT VK-80?

Greeting all,

I looking to replace an venerable Sonic Frontiers Line Stage Once Pre-Amp. I been looking hard at two products. The Audio Research Ref-6SE $17K and the newly released BAT VK-80 $10K. 

These will be mated with a Pair of EVO-400's set up as Mono-Blocks and re-tubed KT-150's I like their snap over the stock EL-34's. My tastes in Pre-Amps is it has to be good with vocals but so overly warm and syrupy. That it cannot flesh out the detail within and recording, or sacrifice tightness and punch in the bass. In short it needs to provide resolution over sweetness. The Amps drive a pair of Legacy Focus SE speakers. These things do not like anything in the signal chain that fattens the low end.

Music preference are Rock, Metal and Classical. Think: Pat Benatar, Heart, Def Leopard, Evanescence, Lacuna Coil, Metallica, Bach Organ Works, and Tchaikovsky's 1812 Overture and you get the picture the bombastic material I like.

I enjoy how both Pre-Amps mate with my system. However, it seems that Ref-6SE dances with my setup a little better that the BAT. My crackpot theory, is its more at home with sonic character of  the KT=150's which is what their Reference 160-M/S amps use.

Nonetheless, The BAT's build quality is more impressive, and I feel I really get something for my $10K. So it seems to me that I am paying a lot for that Audio Research prestige, than quality. Not a fan of a $17k Pre-Amp that comes with a plastic remote. That to me is a major turn off. So what other chintzy things are they doing with this component, in order to increase their profit margin?

Any additional thoughts and opinions are appreciated.
