Best audio companies and dealers

Basis Audio.  Responsive and superb customer service for my Debut Vacuum and Vector.

Another shout out for Mick at Quintessence Audio in Morton Grove.  A very special dealer that goes of their way to ensure customer satisfaction.  I swear he has the magic and could set up 2 paper cups with a string between them and have you drooling.  I am retired now so I can only look these days :-(

Music Direct.  I go into their place and they always spend however much time I need on accessories and music. 

Bob Clarke of Profundo.  Went out of his way to find me an Orpheus many years back (after they were discontinued).  

i also second Uncle Kevin from Upscale Audio.

Glenn Poor in Champaign, Illinois.  I went in there for several hours after driving my niece to U of I.  I didn’t buy anything at that time but he treated me as a valued customer. His setups sounded excellent.

I agree about Basis (I have a Debut vacuum table too, with an Orpheus L cartridge on it right now)--great table and good service.  I had a power supply/speed controller go bad very shortly after purchase.  It was replaced almost immediately with minimal trouble on my part.

I know Bob Clarke and he is a good guy.  I bought the Orpheus L from him and a Viva fono phonostage.

George Lenz at TubesUSA  is also fantastic.  He gives straight answers, including recommendations not to buy one of his tubes because it is not ideal for a particular use, and he communicates after the sale to make sure everything is working out.
