BAT VK-42SE & BAT VK-250SE Pre-Power combo purchase advice

[Arcilius]

Hi everyone,

So I've been building my small standmount (focal/dynaudio) setup and found a good deal for a prepower combo from BAT. I am not familiar with their sound.

The guy had them for around 5 years and he wants to sell them both for $3500.
- Do you think that it is a good price?
- What is your opinion of BAT VK-42SE & BAT VK-250SE sound signature?

I ordered Chord Dave dac/preamp which is to be delivered in the coming weeks.
- Should I buy the VK 250SE alone and connect it directly to Dave? or is an actual Preamp like VK 42SE is required?

Regards,
