...  Just wondering why such a monster of a bridge -- maybe diodes are less noisy when used at far lower than their rated current?

Like the idling motor in a car: very little noise. Wait until you hold the choke in your hand. That qualifies as monster also.

John and Grainger,

Thank you both very much!  You guys rock!  Seems simple enough but the  devil is in the details.  Just wondering why such a monster of a bridge -- maybe diodes are less noisy when used at far lower than their rated current?

I may even have a nice split-bobbin transformer I can sub.  I may even have 90% of these parts on-hand.

Anybody know the O.D. and I.D. for the DC barrell connector for the Touch?

Thanks much -- love this forum!

-- Jim


O.D. - 5.5 mm  I.D. 2.5 Long - 11.0mm   :)  plug size but that should help.

Lar,

Thanks very much -- doubly so for the mouser part number.

Got the new Touch yesterday and I'm pretty impressed with the quality of the piece -- as compared to the original SB, sb2 and sb3 -- all of which I've had in the past.

Did you take the electrolytic coupling caps out of your analog outs or are you just using it as a transport?

I`m only using the digital out, its all stock, as well as the new firmware for 24/192 output. I have an Emotiva Dac connected to it, impressive sound out of a little box. http://forums.slimdevices.com/showthread.php?94512-Announce-Enhanced-Digital-Output-app-USB-Dac-and-192k-Digital-Ouput

Hey Lar, so you are running USB out to the Emotiva DAC. I've heard good things about that relatively inexpensive DAC. So is it asynchronous? I am just using optical out on mine, of course tht is limited to 24/96. I guess I will have to install the firmware upgrade and give it a try.

Cheers,
Shawn

Hey Shawn, I`m using the coaxial out, the Dac is limited to 16/48 in USB, unless you use USB>SP/DIF converter so i just went coaxial. At 199.00 its a steal, but I expect they are coming out with a new one in the near future to address the USB shortfall.
