Thanks Russ. I'll drop the voltage on the Placid down a bit then.

And it has been a fun project... taken me MUCH longer to get to this stage than I planned, but it was definitely not the fault of the Buff32 or the Placids.

Really looking forward to seeing what the BuffII will do here.

Later!

In the 2L HiRes Download - test bench, they say
High Resolution Music DOWNLOAD services

"Prior to entering a commercially available download service for high resolution audio files we invite you to join us in this evaluation of future consumer delivery formats. FLAC is a lossless encoding of WAV-files derived directly from our production original used for the SACD. All resolutions and encodings are derived from the same original DXD source files. ... "

I understand that they record their master in DXD format files and edit, mix down and down-sampling into release masters for SACD, CD, mp3, etc.

When I asked the importance of playing 192 kHz/ 32 bit files, an expert replied to me;
"No need for 192 kHz/ 32 bit replay because no recording on 32 bit. DXD is more important."

Hi Bumpei,

I was only relating my (very limited) personal experience with DXD. I am quite confident if they say they are recording to directly DXD that they are.

Cheers!
Russ

In any case, have every reason to believe it would play them in the same way the demo did.

I would be happy to test it.

Cheers!

Dear Russ,

thanks for taking the time to see if you can arrange a test. You will really be in the high tech frontline with DXD testing


Regards,

I will see what I can arrange in the way of a test.

A question for Russ. What is the current requirement for VD? I'm going to use another supply than a Placid.

It draws ~ 250ma in the standard configuration.

I would use 5.5V

Cheers!
Russ

Is 5v pushing it? are the on board regs going to drop out ~5v? (how much headroom?)

Is there a schematic for IVY III I can have a peak at?

Are we talking about Buf II?

Nothing will drop out at 5V, in fact things should be OK down to 4.5V. Its just that the AVCC reg will do slightly better at the top of its input range which is 5.5V.

I will publish the IVY III schematics soon, but not yet.

Cheers!
Russ

Thanks, understood! I was going to use a 5v reg and wanted to be sure of the reason to use a little more (5.5v)
