Know of anyone in NJ that can repair Musetex Bidat

I'm wondering if there is anyone in NJ that can repaair my Musetex Bidat? It makes a wooshing sound when turned on and I was told the caps probably need replacing. Always loved the sound of this DAC and I would not want to change the sound of it. Thanks in advance.
I would send it back to John Wright and have him modify it to current standards. I have sent mine in 3 times over 6 years and have an EMM Labs PS in my current model. Best the EMM Dac2x but as you know is limited to 20/48 and no USB input.
