You still may want a uC just to turn off the automute.
Thanks for the headsup Ross!

Had a very similar situation on the prototype opus.

Cheers!

On a positive note,

I have had the little rack box with the demo board powered up 24/7 since last weekend. It is cool to the touch. It is probably consuming less than a watt and it isn't enough power dissipation to raise the metal case above room temp.

How hard would it be to have a 5-7 channel version of the DAC board that would support the DSD and all that? I'm guessing it would mostly be just rewiring the outputs and what not. But I'm most likely wrong. Not sure I would need a 7 channel...probably wouldn't be something that people would order a lot either so take this question with a grain of salt

Ross,

Well im very pleased that you have put the part under a microscope and exposed a few things. ALso the fact you are happy with the sound with a couple tweaks of yours is really good. Are you planning to make a DIY kit from your experience or is Russ the one that takes care of most of these? It would be awosme to get this DAC into many hands to see the potential it has. I ask this since doing the PCB's is really not the business my company is in, but its necessary in order to get the part to anyone who wants it.

Dustin

Dustin, doing PCBs is my business. I have been designing PCBs professionally for over 20 years.

I started very young



I have designed hundreds of boards, and some of them have reaped $ millions in sales. I didn't get a commission

The Twisted Pear guys have a nice setup because they have assembled boards for sale. The boards I have sold here on this site have been bare board kits with documentation.

Dustin,

I can only speak for myself, but I do plan on doing DIY kits and PCBs. If this things works out as well as I hope, I think there will quite a few of these out there.

I will actually be ordering my first batch of PCBs for this chip in the next day or two. Probably Monday. So expect a lot of questions between now and then.

Brian Donegan is my cohort and friend. He handles the kit side of things, I just design circuits/PCBs.

Cheers!
Russ

Dustin,

Nice to hear from you.

One silly question, any particular reason you suggested the Denon 1940CI as a transport? Is it a decent CD player as is?
