good luck dealing with Jerry Ozment, I found his customer service to be terrible and will never purchase his products again. To be specific, he took in an Altis Reference DAC for repair from me, a DAC he designed. After $800 and 9 months of sending it back and forth and having to call him and leave message upon message only to ocassionally get a return call, I gave up and sold the DAC here broken at a huge loss.
as always, YMMV, but this experience has made me think twice in dealing with a company who a. does not use email
b. does not answer their phone nor do they have an employee to field calls.
As a comparison, Jeff Rowland has been stellar and I am always forwarded to him when I call for repair issues.
Sorry for the slightly off topic response, but I needed to vent.
