1s and 0s or what? I don't stream. I listen to locally stored music files, so I don't worry about this. Now, when I look for new music to purchase, I sometimes stream music to see if I want to purchase it. I do have a fiber media converter between my wired access point and the music server.
The most over used and misunderstood buzz word is now "bit perfect". He spends time explaining there's no data loss due to protocols. I can agree with that. Technically the stream may be bit perfect but there is still noise. He basically denies jitter, I forget how he dismisses it, I don't agree with that. He measures his $1k DAC it has 113 dB dynamic range says it's below hearing and assumes his DAC is perfect, I guess all sound alike but maybe it's fine for what he is doing. He shows no difference from the output, I have no idea whether he is measuring correctly.
Coincidentally I have that same unit, the Ether Regen. First of all the manufactuer allows a 30 day trial with money back guarantee. So there's nothing to lose in trying one. I kept mine. The difference was not night and day as he claims audiophiles say, it was a good enough improvement I kept the unit. Although it's only $640.00 I'd as soon keep that in my pocket. It's a total insult to tell me I didn't hear the difference.
It would be interesting to get the manufacturer's response.
His final conclusion we hear a difference because when the new item is, inserted we listen harder. When I evaluate a new piece it comes in and out, if the item makes enough difference to warrant the price I buy it. That improvement had to be obvious and repeatable.
Most of us are not scientists so we have no idea whether this ASR guy knows what he is doing. When it comes to tweaks many of them often sound crazy as to what they do. We only have our ears to rely on. It's a shame someone gets convinced they can't trust theirs.
I mean who knew speaker isolation feet would do anything? I'm not even on a wood floor. The Stackaudio feet actually were nearly night and day, like I went up a model in the line or something.
If you don't trust yourself who are you going to trust?
There's also the possibility the unit won't make a difference in every system. I acknowledge that.
