Von Schweikert Research VR-3... still any good?

As far as I can remember from reading, In the mid 90’s, the Von Schweikert Research VR-3 were one of more exciting speakers on the market (on an affordable price) with praises for excellent bass deliver, amazing tridimensionality, natural mids and sweet treble.

But after almost 35 years I wonder if they are still good? Unfortunately I cannot listen to the pair that is on sale (in excellent condition) because it is a 5 hours drive.

Can anyone help me with some information please?

Are they suited to tube amplifiers?

What are the drivers? Is it easily serviceable?.

Thanks in advance
