Buffalo Tweaking

[Ciu]

Hello !

I've got some problems , using Spdif input of the Buffalo24.
I've been using TPA PCM2707 since the beginning I have Buffalo24, as a interface to convert USB (from my netbook PC) to the Buffalo Spdif input : everything is right with this configuration.

Some days ago, I bought a Teralink USB to spdif /I2s converter
What I intend to do was just to swap TPA converter to Teralink converter.
The results I've got are bad, a cyclic noise appears in background, a kind of Kssstttglinggling, (something like a desert snake, funny ?) every 5s, during 1/2 s.
Have tested 2 differents PC Windows XP , drivers(DS, Asio4All), cables, player (Jriver, WMP) and finally swapped Buffalo to Cambridge Dacmagic3, the noise has gone !!!

Does anyone with the same configuration ?

Thanks for everyone for any advice
R.C.

That said, we are actually going back to something similar to the original Buffalo for the next go around to allow more tweaking of the output stages (by popular demand).

Hey Brian, your "Tweakers" board was first mentioned by TP back in Feb 2009 - your announcing something again now?

Thanks for the notes of caution on pin connectors - it's constructive!

Between high parts and mfg cost and time spent supporting users, we just could not get it together to have two versions at the same time. It's a huge risk buying all the parts up front, let alone manufacturing, a lot of these as a hobby.

The new Buffalo will be a combination Tweakers and non-Tweakers board in one. It will work "out of the box" for those who just want a high-performance dac, and offer lots of tweaking options for those who want it.

Your moving house was the last excuse put forward by Russ for it's "delay" - are you saying it was never planned?

[BrianDonegan]

Nice tone.

No, it was planned all along, it just never came together. The version we are releasing is an outgrowth of the board we panned on releasing before. You seem to want it to be some devious plan we have. There just aren't enough hours in the day after work and spending at least some time with my kids and supporting what we have out there already.

No tone just asking a question. You guys always post cautionary notes without any constructive suggestion & usually follow it up with how the Buffalo is either doing it better or about to do something similar but better.

So, as it's a thread that I started about tweaking the buffalo but has since become more like a Sabre implementation thread do you have anything constructive to add? You guys have a lot of experience with implementing Sabre DACs but I haven't heard much constructive?

WIth an attitude problem as big as yours, are you really surprised?

Jeez

When will it be due?

You call it attitude - I call it just saying what I perceive - live long & prosper on starship TP

Ah good question, Lars, I was afraid to ask

And AC-1/Femto...please.
