I had no idea you could use DBS as a customer and not a contractor until I saw a post from Michelle. Michelle and Steve were so great to work with to fit doors that I needed and he was so patient trying to teach me how to measure them properly so they would hang correctly upon arrival. Quality was great, price was great. I highly recommend.

So….I had a 49 year old classic receiver, that went out elsewhere, the Case went to DBS. I’ve owned it for decades. I watched the pressboard walnut veneered cabinet dissolve over the years. I brought the frame to DBS to replicate and they used Solid American Walnut…….absolute perfection…….need I say more. Those guys are all craftsmen and it would behove you to talk to them if you’re in the market…..Stunning piece!

Every time I go to DBS I get the best material and the people are very helpful. Steve (Rocky) gets my material ordered right the first time. If you don't know what you need for a project under mass. Regulations they have the people who will figure it out for you. Great place to go to.
