<sigh> Digital to Analogue

[AlexM]

have now created another thread for FLAC vs. WAV discussion. Feel free to wade in.

It is obvious that there are entrenched or conflicting opinions and experience over compaction/decompaction of digital files (audio in this instance) and software applications, but this is contributing nothing to Graham's original query, has been voiced as a diversion elsewhere, and really should be taken on in a new thread should the subject sufficiently merit discussion and examination...

That's a bit rich from you to say the least .
Opinions and experiences are two different things. I speak from personal experience with regards to FLAC, and so do many others. Those that offer the opinion that there is no data lost in FLAC are not speaking from experience, but have the foundation of their argument embedded in what they have read somewhere on the net or a magazine.

Does this mean that unless you have personal experience of something any reports pertaining to how something works for example are to be taken with a pinch of salt?

[AlexM]

Stan,

No I'm not. I have direct, first-hand experience that is odds with your opinion. FLAC compression is completely reversable, and this is an experiment you can do yourself easily, so do it or don't do it, but please don't tell others that have and know the result that they are talking out of their hats as this is beyond doubt.

Now if you want to talk about why they might sound different then please enlighten us as exploring this might be enlightening and useful. Just out of curiosity, have you experienced this difference both via SPDIF and USB inputs on your products?.

You may carry your presumption to the other thread specifically for this discussion Stan, and for the record it is not formed on the basis of what has been read, but rather the experiment to see for myself.

Get a better system .

The buzz that you have discovered is obviously a PSU related issue, either because of PSU, Netbook regulators, or the usb/link to the DAC.
I have no experience with Stan's DAC, but believe not to be USB powered, so it may be worth decoupling/chopping the power line on a spare/cheap usb cable to see if this is the cause. I am not sure whether the Caiman is galvanically isolated. Stan could perhaps comment on this with some knowledge and authority.

Hi Graham, done very quiet here now.
Did you get anywhere with the annoying PSU buzz?

Work intervened

So tomorrow I have time. Definately gets much worse when I plug the power brick in
Unplugging the USB cable and any sign of a hum goes away. Bloody annoying.
However, on the bright side I have waded through a couple of Terrabytes of digital files and I actually have nearly four hundred Gigabytes sorted now, only another onethousand two hundred odd gigabytes to sort now

You have a ground loop caused by your power brick being earthed. Find a way to disable the earth on it, with a laptop this SHOULD be safe. I have the same with my laptop. I created a 6 inch extension lead with no earth connection. Or use a galvanic isolator on the USB.
