Usher 6371 vs Von Schweikert VR4jr

Well I found 6381's for a great price and the VR4jr's also. I am leaning toward the Vons from what I read and heard from many people. They are both excellent. My big draw back with the Ushers, was I did not realize what kind of beasts they are. They weigh a lot even before you fill them.
I also like what I read on the Vons and there sound. I am hoping, of course buying without hearing, that they will be musically for me.
I guess I will find out shortly.

One of the big problems for me also is that I live in a part of PA that limits the audio stores within a 100 miles. So I always buy without hearing my gear first. So far I have always lucked out.

Well I am picking the Von's up on Sunday. I ordered some Paul Speltz Anti cables to biwire them using different taps on my McIntosh that has the autoformers. I hope it all sounds like I think or hope it will. If not I guess I will try again after giving it some time to grow on me.

Well I hope as well to have a good match. I will be using a McIntosh 6850 for the amp using the 4 and 8 ohm taps on it to biwire.
How is the bass? Do you feel like you need a sub? I read in another post that the claimed 25htz was not realistic, but then I read the review and it said it was real. Any feedback?

Do you biwire them? Did you notice any sound changes?
