Good to hear you found and are enjoying your Valab Dac. Still using mine for about a decade now. https://www.head-fi.org/threads/valab-nos-dac-subjective-listening-and-modifications.413540/ With the information provided by the people active on the above linked thread, I did some...

been running this unit all these years, still love it

here is a link to the 16 chip unit https://www.ebay.com/itm/1pc-TeraDak-V4-5-TDA1543-16pcs-Parallel-Audio-decoder-24Bit-96KHz-USB-DAC/273512581004?hash=item3fae9ec78c:g:CDoAAOSwiiVbxycb:rk:8:pf:0

TDA1543 is the Dac chip. They use 8 of them in parallel, the Chameleon used 16 in parallel. those chips are fed straight to output. They sound great, mine is modified. Many people on these threads thought these units are top notch. In my limited experience with Dacs, this one sounds best.

These DACs were always sold on ebay, look up teradak dac on ebay. I could not find any chameleon dacs there, the ones that are there are the 8 DAC chip version. I have been running one of those units for the past decade. The threads here about the Valab NOS DAC and the Chameleon DAC fizzled...

compared to regular ubuntu, SE is excellent, way better implementation of pulse audio,    i have heard different things about other processes interfering with sound quality,  i have a gizmo called an ultravox, it isolates the usb signal from the computer power, so that helps     if...

for anyone using linux ubuntu, i suggest getting Ultimate edition, it is ubuntu based, it does sound way way better

yeah, thanks wood   so then does your musiland reclock?

Does the ultravox not work with the hiface and the off ramp  because of the need for asynchronous information flow?    Assuming the adum/ultravox only sends traffic one way....what if you used two adums, one going each way, could that be done?

Quote: i hardly think that is neccassary,  there is a usb input on the chameleon, so usb talk applies here, people are always chasing any computer related talk to it's own forum, i hardly think that is a useful approach on a forum that is seeing 2 or 3 posts a day,    if there is a post...

i think many users of this thread have stopped coming here, maybe out of awe at the recent changes, my question is...., where else can we go?

Quote:  i would like to see what happens if Newk puts an a/b adapter at the off ramp, and a cable to the computer   i also don't know what kind of a power supply is attached to your ultravox Newk,  i think people recommended a 'wal mart' power supply,   i am sure it works..- and i...

i like the ultravox, less mush, more extended highs i experienced no loss of soundstage or imaging or channel seperation   i have a short cable from the ultravox to the dac and the longer cable to the computer, i figure pre isolator cable noise is going to be removed by the ultravox  ...

ok , i got my ultravox, i powered it with a plug in transformer that i cleaned up by adding some capacitors and some choke coils before i fed it's  9 volts to the ultravox..., everything worked  right away, green light shining, usb lock light flashing, back to best sound ever for my system, it...

what soundcards have i heard?    over the last 20 years i have heard a lot, including sound cards integrated onto mother boards,   i do not know the exact brands and model numbers, sorry.   The onboard sound on some of  today's motherboards sounds better to me than soundcards of ten years ago...

Quote: possibly, i have thought of that... any other ideas out there?  

has anyone ever experienced this coming from their dac.... a sweep signal that lasts about 1 or 2 seconds, starts at  low frequency and sweeps up to high frequency and then it is gone.... this has happened about once a month at apparent random moments....

This thread has deteriorated to a debate on 'is windows better or is linux better.'   Maybe you could start a thread and anyone who is not tired of the debate can go there.   Meanwhile, this thread is called linux-for-sound... so anyone got any thing to say about using linux for sound.  It...

The change happened.  It will never go back to the way it was.  This site is now a commercial interest.  Money is king.  Deals, I am sure, were made.  Costs must be recovered.   The only way to stop such events from happening is through group ownership.  Figure out a way to make a site like...

I like the idea of isolating away from the computer power supply. I was glad when wood first mentioned the ultravox. I ordered one this afternoon to use with my valab dac. I use usb all the time. It will take a few weeks for the ultravox to get here, but i will try it and report my findings...

Thanks to what i read on this thread, I just replaced my Conrad Johnson pv3 input caps with a couple of FT-3 teflon capacitors. There are still 2 capacitors in the line through the preamp that i am planning to replace as well. On ebay, there are .47uf 200 volt FT-3 caps that the seller claims...

I feel i have to add some balance to the recent posts on this forum. People who have problems with their dac sometimes need to post a lot before they can figure out what went wrong. This makes it seem like the dac is troublesome when in fact most folks probably have few such troubles, so you do...

wood ----thanks for that detailed description of teflon burn-in
