Product: Sonus Faber Concertino Domus Bookshelf Speakers; w/ Stands

I think you have paid a fair and usual price assuming they are in good shape.

FYI:

The stands were $700/pair, so around $2,200.00 retail.

I think you did ok too.   I am using a pair of 22 year old Concerto and they still look and sound great.   

Buying those back then was like spending $3400 today.    Enjoy , those are great speakers. 

Lots of times with the interim inflation you will spend about the same price 20 years later on speakers. I would enjoy them. I think that is fair price in todays market. 

They were $1,495 a pair including stands.
