I have used a regulated battery power supply for it and don't notice a difference with the Y1. Also used the recommended wall wart and don't hear a difference.

Hey Now,
I just went to pull the trigger on my Mouser order only to discover the FK24X7R1E105K caps are back ordered. Can I sub in FK22X7R2A105K? The only difference I can see is 100v vs 25v working voltage.
Thanks,
Bill

The FK22X is physically too large to fit.
EDIT: You can use Mouser #810-FK24X7R1C105K as substitute.

Project ordered.

Does anyone have a Mouser BOM I can use to paste into their BOM tool, for either the Full or Lite config? If you have created a "project" at Mouser for either, that would be even better. If not, I'll be creating them to share..

Here is what I have, the receiver is missing due to backorder

Edit: receiver added, still on backorder though. Digi-key has it in stock.

Are you planning on fixing that?

Just a heads up, TORX147PL is back in stock at Digi-key. Unfortunately, not the TOTX147PL. You can still get it from Newark or Farnell, or use the module from Sys Concepts I linked in post #752 above.

I should have PCB v1.01 very soon, which will also support the Sharp GP1FMV31TK0F (Digi-key 425-2605-5-ND).

Yep, I chose the option to have my order held until that part was in and could ship.

My email from Digikey said that the TORX would be available approximately July 31. I guess it's approximately close enough as they show 1,160 available just now.



EDIT: I just now recieved email confirmation that my order has been shipped today.

Just finished my y1, and am listening to Fourplay through iTunes and my

PPA as I type this. Worked first time. Very nice. Clear and detailed with

plenty of punchy, low bass. I'm using the Silmic II's on the output

bypassed with these 505-mkp20.1/100/5.

I did the full++ in the B2-080 case, but don't yet have the Toslink parts.

Can't wait to add the y2 board.

Thanks Ti for another great design!!

I've found that a regulated supply sounds noticably "better" than USB supply on my y1. I normally have it powered by a linear regulator (a rudimentary 7805-type jobbie I built), and when I unplug it and it automatically switches to USB power, there's a noticable (if subtle) deterioration in audio quality. And vice versa.

I should add that I'm not especially golden-eared.

I should further add that even when USB-powered, it sounds much better than a motherboard or laptop audio-out.
