Hi,

First? That was quite a while back.

Brian is in the process of shipping out current orders.

Cheers!
Russ

Okay, here's what's up:

I opened up for pre-orders for this round on June 30th, and sold out in about 8 hours.

A large percentage of people ordered IVY's and power supplies, so I have roughly 3x kits to get together, in addition to the Buffalos to build and other bits people ordered.

I am on track to ship all of these this week, starting today, hopefully (if the day job doesn't get in the way too much ).

I hope to have another batch available in the next few weeks, but since for each Buffalo there is typically three additional kits I have to build, and I am a one man kit building show, I will need to keep the batches smaller to keep my head from exploding.

The benefit of this will be more chances to get one if you are not on the forums or our site all the time. I will make an announcement of when each batch will be available well in advance. They will likely be available every 3-4 weeks to allow build time.

I believe that when we speak of absolute phase inversion in a digital product, the signal is "upside down".

Since the Sabre has a differential output, you can just treat the left channel + output as really being the -, and the left - as the +. Just swap the wires. And ditto for the right channel.

It's not so easy to deal with if you use a DAC that is single ended and not differential, but we don't have that problem here in this thread on the Sabre

The Sabre chip itself can invert signal if neeeded

AsI havnt recieved the kit yet I havnt read the ESS or T.P paperwork,,but is the invert function a software option or a simple pin/dip ground issue that would enable a front panel switch.
Also Dustin I would be interested to find out the reasoning behind your choice of the bitclock at 64fs Vs any other number ie 48fs as per the Philips CD PRO2 - as above, this means the dac and transport arent "plug and play"compatable.

Default digital volume control?

I always thought that digital volume control was "bad" and all volume control should be done in analog. Reason: you only have so many bits, so if you digitally scale values from (let's say) 0-255 to go only from 0-15 you have only 16 different levels left when you started with 256. If you scale in analog you still have 256 levels between 0 and 15. The latter presumably having more fidelity. Is that argument missing the point?

(I hope not to unleash a big argument here... Just point me someplace I can educate myself.)

Or is this something that's special about the ESS chip that it can do this the "right" way and the above argument is still correct in a more generic context?

I haven't done a ton of reading into the actual setup of this yet, so tell me if this is an ignorant question, but is there a suggestion for the needed transformers?
