Looking for a Marantz repair shop in the Philadelphia area?


Does anyone have a recommendation for a repair shop for a Marantz NA11S1 in the Philadelphia area.   The Marantz web site directs me to a Trenton repair shop which is no longer in business and also directs me to a Delaware shop which did not impress me over the phone.  

Please share your Philly repair shop experiences.

@mysearcher257 , any update on your end?

On my end, United Radio still has my CDP. At first they told me that they could not fix it because they could not get the parts. Then I called Marantz who said that they did have the parts. Then I spent another week or two trying to get United Radio to confirm whether or not it could be fixed.

They called last Friday, 11/11/16 and said that it could be fixed for $275 + return shipping. I gave them the green light. Then United Radio called me back again tonight to tell me that it can be fixed, and tried to charge me again. Once I told them I paid last Friday, they did acknowledge that it was received, but not entered correctly. I asked about a time frame, they could not answer that.

I have to say that I am a bit nervous. They are nice enough sounding people, but their competency level concerns me.
Alright, I received my modified Marantz SA-11S1 back from United Radio. New drawer seems to work perfect, and CDP sounds great!
Total was about $350 including shipping.

It would be nice to have a trustworthy repair center local to Phila, PA. However, it is just nice to have this classic older CDP repaired and running fine again.
Wow...finally my marantz NA-11S1 has been repaired and returned from United Radio.  The unit was shipped to United Radio on February 22 and returned yesterday May 15.  It took many many weeks to get the parts from Marantz. Once United Radio received the parts, they repaired it quickly.  

The crazy thing is the needed parts cost only $1.74.

I would recommend United Radio for Marantz repairs; they did an excellent job.  Good communications.  Good return shipping.  Far pricing.
