There's no shortcut for cleaning up digital audio is there? So as I stare at the little HRT Microstreamer in my hand, I wonder ..... is that why it sounds just like the other mini-DACs, and not like the breakthrough they promoted?

Hi Dale Sooner or later, they will hopefully realise that digital is only as good as the care you take with it, right from the ripping stage, and that it's almost impossible at this point in time anyway, to fully recover from any earlier damage to it's SQ., no matter what they do at the DAC stage. Despite all the claims, it's every bit as fragile as the LP that it replaced. Even the actual storage medium plays a part, as they have found with BluSpec and other formulations such as MAM Gold CD-Rs, as does the type of Laser and the speed used to create the master. As you remarked previously, we need to cherry pick all of this combined information to paint a more complete picture. As smart as they are, none of these guys alone has the complete answer. Regards Alex

I've had opportunity now to refer people from several places to John Swenson's #1 and #2 articles. This should spread a lot of awareness, not because of any special effort I make, but because the subject gets people's attention when they get wind of it. I had some of the early CD's, made with some really awful ADC's, and I've replaced those now with better copies. But downloads are the thing now, so who has a plan to archive their downloads safely?
You've talked about the difference between various delivery or archive methods, compressed versus uncompressed zips and a lot more - do you suppose Cookie Marenco and/or some of these digital guys like Swenson are working on a "better wrapper" for digital files, so when a user downloads a music file they can archive that fully-wrapped track and there would be less chance of degradation, as long as the archived data stays intact? Presumably the act of unzipping the track would simply copy the data to the music player, but not make any changes to the data (i.e. "read only").

Hi Dale I doubt that there is much more being done than Cookie Marenco is doing with her uncompressed Zips. Although Swenson and others are finding these problems, being typical EEs they don't seem yet ready to accept that Digital has problems right from the creation and ripping stage. Barry Diament and others have found that even the speed the stamping master is burned at makes a difference. Even pressings from different plants can sound a little different. Historically, many have preferred the CDs made from the original pressing plants in USA or Japan over the local products, even though they contained the same data. I doubt that they thought much about why those from the original record company sounded slightly better though. Add to that, the improvements made by using better polymers in the CDs themselves, and other improvements such as burning the master with Blue lasers. FWIW, the DVD-As that I have ripped from downloaded ISOs sound identical to my own copies after being ripped using DVD-A Explorer. I have yet to have a wake up coffee , so I may be rambling a bit . Regards Alex P.S. I talked to Barry about supplying his files as uncompressed Zips on his DVDs like Cookie does, but he said that a few people had problems with Zips. I was able to provide a Sydney C.A. member with a better uploaded comparison .wav file than he was able to DL from the Soundkeeper comparison page, using my DVD from Barry. I extracted the track with Windows 7 in Safe Mode using the LG BR writer with it's JLH PSU, and saved it to a Corsair Voyager using an external JLH PSU. I UL it from the Corsair as an uncompressed Zip. Up till then , he couldn't hear any real difference between 16/44.1 and 24/96 from the format comparison page.
