BAT VK-3i / BAT VK-30 or Herron VTSP-1A pre amp


I can not decide which of these pre amps I should upgrade to. Anyone having information or suggestions, please leave your comments. This is will be my final factor in choosing to buy one or the other, thanks.

Kw6 asked what the Line 3 does better than the Vk-3i. IMHO the Line 3 is better in some very significant ways. It's more dynamic, more refined, and more extended. It throws a huge soundstage and it has greater resolution of low level detail. I'm hearing many things that I hadn't heard before -- and with considerably more realism. I like the ergonomics of the Line 3 a bit better than BAT's. I can change phase and switch to mono using the remote. The
muting function is neat in that it gradually raises the volume when mute is turned off. I do miss the BAT's volume presets though.
I have been running a VK 30SE for about a year. Definately worth the upgrade. I agree with some comments pertaining to using good cables. The company is fantastic with customer service. Can't say enough good things about it.
