Does anyone know where I can get a test track that is in 192KHz / 16 bit, 44.1KHz / 24 bit and 192kHz / 24 bit?   I realize I can do this myself with dBpoweramp, but my understanding is that most software out there just truncates the extra bits off.  The process requires dithering and needs...

Quote: A lot of us (including me) have just pulled out the 47K resistors and put them in the bin.  My "output stage" consists of a 360R Texas Components TX2575 resistor and a 2.2uF Dueland Audio VSF Cap.  That's it.

Quote: Hi Chris,  You need to measure the output with a 0dB 1 KHz sine wave. Download this free app and you can produce any frequency & level you want:  http://www.tropicalcoder.com/AudioTestFileGen.htm   The blue trim pot (variable resistor) should be adjusted to get an approximate...

Quote: Hi Chris,  I ordered a pair of transformers over a month ago and I am still waiting....  Grr...  What output caps did you have before switching over to the cinemags?  I have a pair of Duelands & Texas Components in my VALAB.  Just curious on your setup before the cinemags and the...

  Quote: Bill,  I was thinking about adding a SSD drive using the Firewire 800 connector (the fast one) using a case like this:   http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150436588133&ssPageName=STRK:MEWAX:IT   Means the SSD is external though.  I am currently using a...

What do people think the improved SQ of the Chameleon over the VALAB DAC is most due to?    Is it going from 8 TDA1543 chips to 16?   Better power supply?   ?   Has anyone tried running the Chameleon with just 8 DAC Chips?    I am working on a bit of a project and I am...

Quote: I have the HiFace and in my system it really cleaned up the sound.  Huge improvement for the money spent.  It comes with either a RCA output or a BNC output.  Either way it is a USB to SPDIF interface so it outputs SPDIF - you just have a choice of two different connectors.

Quote: The Duelands are far to large to fit inside the standard Valab box.  You have to buy another box to put them in.   The caps you buy will replace the stock caps.  Throw the stock caps in the bin!

Quote: Nope, I have never heard that.     Maybe something upstream of the DAC?

M2Tech USB to I2S Module   Found this over on diyAudiuo forums.    http://www.diyaudio.com/forums/group-buys/166354-hiface-usb-i2s-24bit-192khz.html   I am not sure if it will give a 5 volt I2S output that we need.  I have asked audiodesign.   Here is the data sheet:  ...

Just ordered a Ultravox.  Going to use it with my HiFace and will report how the 2 work together

Does the Chameleon have those incredibly fragile inductors that the VALAB had ? Problem sounds similar to what I had. It ended up being the inductor that connected to the DAC board.

I have just finished most of my mods on my VALAB NOS DAC. It was my first ever mod and at times I had my problems but thanks to many generous people out there such as: marcelnl, PatOMalley, MikeW, errnst, Wood and of course Bill Allen the sound out of this DAC is better than anything I have ever...
