Bi amp configuration...a mismatch?

I would not do it, as they have historically not been a difficult speaker to drive.
Is there something about the sound that is not appealing?

You’d be better IMO to get a Vandy sub and the crossover between the pre and amp. that is not usually noted as being subtle… Most did that it is usually easy to hear an improvement.

I am just telling what myself and other users have noted.

Almost all people with a set of 2C like the Vandy sub, and it removes a lot of the power requirement from the amp, so it is somewhat similar in concept to bi-amping.
That “takes it to another level.”… and almost guaranteed to be a higher one.

Fewer noted a high appreciation for bi amping and bi wiring.

But maybe someone on the Vandy forum has better input.

It could also take it to another level, but a level that could be a lower level.

Many others “take it another level” with an upgrade to a different Vandy speaker (from 2 to 3, or Treo, Quatro, etc...)
