Ret-row.

Ret-row.
Thanks to you also MisterX (by the time I got to the bottom of the y-1 BOM, my mind was numb LOL, I just finished ordering).
You probably don't know just how many times I have read your posts about DAC's and just about everything else, not to mention personally helping me with sourcing parts for a project.

Just how on earth do you even begin to approach designing an audio DAC anyways?
Thanks a bunch MisterX! I should have known this was a team effort.

then why are we rushing to do the AMB order next week?? or are we just ordering the bords while they are still available and doing the mouser/digikey order later??

edit: oops forgot our conversation the other day so we get the boards; face plates etc. and then just slot the USB controller in when it becomes available.

I love reading this kind of enthusiasm and excitement generated by our hobby. It almost sounds like we need a group hug to go along with that group buy!

:P

Sorry for not updating that comment. Apparently earlier this week stock of the PCM2707 were depleted at all known suppliers. Somehow, someway, they have reappeared in stock at Digikey after the expected date was indicated as Feb '09. I had originally planned to look to a GB in January, but it seems that there is a window of opportunity now to get all the parts together.

Thanks, great info that will be useful very soon. I can see now that this will be a great learning experience for me.


And to FordGTLover, I just ordered the PCM2707 from Digikey, and all went through without any backorders.
They showed over 300 in stock and ready to ship when I placed the order this morning.

amb--

Do you have any idea when front and back panels will be available to those that missed the group buy?

I am not 100% sure, but I think he may have ordered some just to sell through the AMB store, and you never know when someone who ordered the set in the group buy may back down, not to mention that a set could possibly show up in the Cables etc. FS forum here.

I did get a few extra panel sets, but I have to hold on to them until the group buy shipments end, because a few participants had indicated variable quantities depending on price. Also, there are a few people who contacted me after the close of the sign-ups, so any leftovers will go to them on a first-come, first served basis. However, I am not adding any more names to that list because there won't be enough panels. The group buy panels are expected to arrive around December 29, and I'll send them to all participants thereafter.

After that, I will begin to offer the panels on a made-to-order basis just like I do for the Mini³ ones. So, for those who missed the group buy, the panels will still be available.

So the ones that have done an order from mouser, what were your totals.

Also AMB ealier you said that if I would need to build two different power supplies if I wanted to run the Mini3 and the y1 off of the same wallwart. What if I know that I will be using a 15v power supply, could I use a Tread and power it down for the y1? I would let the power supply in the mini3 handle its side.

I am in need of a DAC that is dead silent for my PC and cable TV box.

Is there any possibility for it to accept two optical inputs?

If I were to use USB for the PC connection, would it "dirty" the signal?

I am sort of of the fence right now, if there are boards with the chips pre soldered I'd jump on it.

it has coax in as an alternate so why not just get a monoprice.com opto-coax converter and then you have 2 opto in's. the monoprice units are in the $10 range.
