Bi amp configuration...a mismatch?


I just recently acquire a pair of Vandersteen 2ci and currently I am using a B&K ST2140 amp to power them. I am planning on getting the Audio Research D70 for a bi amp configuration and my first attempt to tubes in my system. I have a Rotel pre to drive the amps since this model has two preouts. My question is s, do you think their is a mismatch with the amps and preamp to drive the Vandersteen? Thanks

I have always been under the  impression it is best to use identical amps when bi-amping.

True but in the situation where the bass is crossover very low I see no need to get identical amp IMO.  The D70 would be use with the main speaker.

The only issue is if the gain is not identical in each ampllifier, this can make you consider a passive volume control on the louder one.

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.

holmz, thanks for your response. I really enjoying the sound of the Vandersteen but thought I would take it to another level if I went to a bi amp configuration.

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...)

In my opinion, bi-amping should not be undertaken without first asking the manufacturer’s advice. See article below:

These speakers are prime for bi-amping being 3-way designs.  1 amp for the woofer the other for the mid and tweeter.  

as long as the gain on the amps are the same go for it.

i did this with some PSB tower speakers where the 80 watt 29db gain amp was sounding strained- of the woofers drive the amp to clipping the midrange and treble suffer and sound unrefined.  

i added a 150 WPC 29 db amp to the woofers and the sound was amazingly better- more powerful bass and never any strain or lack of refinement in the midrange or treble
