Problem with brand new black ARC Ref 6

I thought i would write telling you about my experience when i purchased my brand new black ARC Ref 6 preamp about a month ago. It was working fine for a few days and then when i went to press the tube hours on the remote to display on the preamp the unit would cut off, or go to a different auxiliary. It would not happen all the time but often enough to know something was not right. I contacted ARC personally about this and Evan from ARC said it could be the remote. He said to bring it to my ARC dealer that i had bought it from and try his remote from his Ref 6. Same results as before. I was very disappointed as this did not solve the problem. I called Evan again and told him it still was malfunctioning. He said he never ever heard of this problem before and asked me if i wanted a new preamp and said he was so sorry about that. Since it was being returned i asked him if i could get the natural silver instead of the black he said no problem . Within about a week or so my new ARC Ref came to my dealer and all is fine with this one. I just want to say that dealing with ARC they are awesome and second to none with dealing with a problem. They take care of their customers with the very best and professionalism one could ever ask for from a company. Could not be happier !!!! Also i am in NJ and my ARC dealer is Audio Connection in Verona... John is the owner and he is an awesome guy in the business.Knows his components inside and out... I have been dealing with them since 1990 when i first bought my Counterpoint SA 220 amp and SA 2000 preamp. He is and was always there for me with any questions or concerns or problems. Truly old school.  Thank you Evan from ARC and  John from Audio Connection !!!!!!!!!
