A number of inmates have been e-mailing me about when this review will be ready. Here it is:

fmak, time for you to chime in with your extensive experience with some of these products.

I generally agree and have posted detailed comments on the iFi products.

I do not find the colouration of the Purifier acceptable with well-honed usb audio connections. They do help poor ones.

"They do help poor ones"

That's the main intention of such a filter.


A filter always introduces losses on its own.
Too much filtering is never been a good idea.
Chaining up filters usually makes things worse.

That's why such a filter works for some people, for some it doesn't make any difference and for others it makes things worse.

It's that simple.

The nice thing about having a "poor one" is that a 99$ device can easily lift the device one or two classes up. Audiophile brands just charge you several 100s extra for doing a little internal filtering by applying 5$ in parts.

I think you miss the basics in the article. That's why it is pretty much useless.

Efficiency of such filters and cables "heavily" depends on the associated equipment.

There are DACs with heavy filtering, signal refresh or even galvanic isolation and others with less. There are PCs with better others with worse USB ports. There are DACs which need the 5V line others won't.
There are cables with filters included others without.

On devices and setups with heavy filtering already in place things might get worse. On devices with less filtering things might get better.

Basically to make sense out of all of this, you can't avoid to try such a device yourself.

Cheers

Mercman's correctly identifies the generic effects of the components, which are ther to fix poor computer usb audio outputs and not dacs specifically.

Whaddayamean "read the article"? Whatever for? What a strange question. We can comment perfectly well without having to read things, thank you very much.

Seriously, I thought it a interesting review, fair and credible.

Yes you did clearly point out system dependency. The article was fine. :)
