tube amp will drive von schweikert VR4-jr?

I would suggest 100W minimum. I have a 50 watt ASL amp and it drives them ok, but not in triode mode. I am going to give the bass 200W each channel with solid state and use my ASL tube amp for the mid-high at 30W. The bass driver uses most of the power.

Fishwater, Have you thought of using a SS 100-200 WPC amp for the bass section instead. I think SS on the bass will give you good impact and leave the quality tubes for the midrange and highs? just throwing it out there.

Fishwater,

What isn't a PITA in hi-fi. just kidding, I know what you mean. The manual actually says that an outboard crossover isn't necessary becuase there is one internally for both sections. It also mentions good results for a 100-200 wpc SS for woofer and 30 wpc tubes for Mid-hi. But as you mentioned, it could be tough to match the levels. I don't think you'll get the best from the bass with 60 wpc tubes used for the woofers. I hope I'm wrong though.

Does the VK60 have a 4ohm and 8ohm option for output, because the mid/highs are 4ohm, and the bass is 8ohms?

I ask because my tube amp has an option for both, and it made a world of difference matching the 4 ohms. I would like to with a bat eventually for the highs anyway because I've heard to many people talk about how well they match together.

The DB99 would be great and require much less power. Good luck. I hope you get them.

Thanks for the info on the BAT. I will most likely go that route in the future.

Oh, yeah I pulled a little dislexia with the impedance.
