H-CAT DAC

@trelja My HCAT remote also wasn't working for the preamp that I have.  I emailed Roger around Nov/Dec and he quickly replied me that he could send me a part (the buttons skin), only to suddenly disappear after I told him where I am located.  Since I cannot use a universal remote for the preamp, after that I continued to email him for another couple of months unitl I gave up.  I wanted to buy more products from him, but how could I?  

FYI Roger Paul passed away recently, no idea if anyone else has taken on the business

@folkfreak thank you for providing the link.

In retrospect, I should have remembered to update this thread after hearing of Roger's passing.  I apologize...

Thanks @trelja and @folkfreak for the update. May he rest in peace, I liked the HCAT preamp a lot, and I don't know what to replace it with now...

@pepperidge Can you open the preamp cover and adjust the volume?
Roger built a fully balanced preamp with XLR input and outputs for a friend last summer.   I think it's only one in existence.  His preamp has manual volume control.   Roger was working on mono amps ... my friend emailed him last week for update and no reply.   Roger makes good stuff but unfortunately didn't catch on.
