Yes it was there in the very first Philips chip set (along with the never toggling uncorrected error pin).

Richard, the CD player is the source. What we have to care of is the quality of our DA converters.
Here a digital central unit, the digital equivalent of our analog preamp ?
In an ideal multiway system, i should consider to build for each speaker a separate amplifier+ DAC + analog remote volume control + PSU.
Feeding each of them with an optical link from a digital multiway filter system / switcher. And this central unit receiving optical digital signals (or wifi radio signals) from the sources. No one ground connection between any AC powered unit.
In regard to CD transports and their problems, I think it's time to re-post the link to Ed Meitner's patent. He describes them very nicely. Note that patent was filed 20+ years ago. Most CD/DVD/SACD player manufacturers still pretend that such problems don't exsist.

What are you after Dejan?
Which is your CD player?
A good idea. I haven’t seen such a product but you can modify a USB cable or the USB input of the DAC
>Edit. In case that the DAC box has inside a DC/DC switching converter, there will be not much of an improvement

My back-ground music CD player is a Sony DVP-CX985V Its toslink output goes directly to BenchMark-2. It plays thru my main system amps/speakers. The comparison is USB/SSD stored HD files plugged into an Auraliti Pk100 and its's digital out to a dig in on the BenchMark-2. Same amps/speakers/room.

Possibly not, HRT boasts of greatly improved isolation in this device so that might be closer to the mark. I wish i could properly measure the output but it must be quite clean, it certainly sounds that way to me. Maybe there is something to the asynchronous hype after all. It's an impressive little device and a noticeable improvement over my other DAC which uses an external supply.

I meant that running the devices on a battery might not be the reason for the improvement this device brought to my system. Like i said, better isolation and asynchronous USB might be the real reasons.

The fact that it is multimode and plastic doesn't necessarily means it is nasty: multimodes can easily manage 10Gb/s nowadays, which should be sufficient for most not-too-demanding-customers, that is non-audiophil(iacs) listeners.
What counts is the actual error rate, from an end-user perspective: if you get one unrecoverable code violation for every 24h of program, that is probably acceptable, nasty plastic or not: that is the way digital links have to be evaluated.
Of course, for transatlantic cables and terabit backbones SM fiber is required, but they are dimensioned to have a (corrected) BER comparable to MM on shorter distances.
No transmission medium has an obvious, intrinsic all-round superiority: for example, the FTTH model is now seriously challenged (or complemented?) by copper alternatives, like G.fast, the next-gen DSL.
In short, don't jump to conclusions based on ugly looks only... it could be seriously wrong
Toslink requires extra circuitry at each end to process the signal, opinions vary online as to the effect this has on signal purity. I did my own comparisons and my impression was that toslink produced the kind of sound that the original detractors of CD called 'artificial digital sound'. I got the impression that coax sounded more natural in the system i was using at the time.

Galvanic isolation was one of the reasons i bought the music streamer iii.

Noise levels seem low even without it but it does show an improvement, at least in this article.....

As long as you are in the digital domain, there is no "Kind of sound". Just datas, with errors or not. And you can compare it objectively comparing them. No room for poetry. As said Scott, any error, executing a program at GHz in your computer can, most of the time, lead to a blue screen. Is-it so often ?

Esperado - Like i said, opinions vary but quality of implementation is important. Maybe a more expensive DAC would have swayed my opinion in favour of optical.
I've just read this article, it supports using both galvanic isolation AND asynchronous USB.

I'm no expert but my new DAC is definitely an improvement over my old one.

Sorry, my forgetting that not everyone is native English speaker and would get my feeble attempt at humour.
