Amir's measurements would reveal this. Would they? Do you even know if he is measuring what is important? Does he?

LOL. Is your faith in the ISO so weak that you have attempt to hide it? Or do you just insist on a belief in your magic dust? Although Amir would never let any personal animosity to bias his results, I'd think you'd want a reviewer to look into things without throwing him personal insults before hand. A very sad and lame approach from a supposed engineer Alex Afraid? Lack of faith? Don't be such a jerk..... Alex just doesn't want to deal with the person and his apparent agenda.

If you find a real difference, people who were buying it without that are still buying it. If you find no difference, it could hurt his business a little (though probably not). So with trouble keeping up with orders he isn't taking any blind tests nor worrying about any measurements. The only important measures are those related to this: $ Did Alex run over your dog or something? He doesn't deserve these kinds of comments. He's in business to make money, but in my dealings with him, money has never seemed to be the overriding concern. The concern has always been with the quality of the products and customer satisfaction. Solstice380, sockpit, Middy and 3 others 6 Link to comment

I.e., reduce or increase jitter. You are looking at too narrow of a picture. If all you consider is the digital signal itself, there would be zero reason to to buy any type of decrapifier. You have to consider the effect ground loops, AC leakage, etc., have on the receiver USB PHY. In other words, you need to consider all aspects of what the ISO Regen does and how it might affect the music to judge its effectiveness. Not just jitter.... Link to comment
Speed Racer Posted June 4, 2017 Share Posted June 4, 2017 I did a Google search and could not find a USB 2.0 optical isolator that supported High Speed (480Mbs) mode. The fact that pkane2001 does not understand that USB 2.0 audio uses High Speed mode and the optical isolator he refers to does not makes me wonder why he is even posting..... Link to comment

Speed Racer Posted June 4, 2017 Share Posted June 4, 2017 No, not extenders. A device designed as an inline isolator. I'd used an Ethernet extender before I would use an optical extender. The product you came up with retails for $1499.00. Link to comment

Hopefully at some point in the near future. Filters....where is the roll eyes emoticon? Discrete filters are a waste of time in my opinion. You guys do what you want there..... As far as I am concerned, the best solution for my situation is an Ethernet streamer/end point device that has ultra quiet minimalistic circuitry/power supply and outputs AES/EBU at the music's native sample rate. Oh, it needs to cost less than $500 too. I will add a music server to the mix. This gets the music off my laptop into a dedicated setup just for the music. It eliminates USB and all the associated crap that goes with it. Link to comment
Speed Racer Posted June 7, 2017 Share Posted June 7, 2017 Would someone send Amir an ISO Regen so we can put this thread out of its and our misery....please! Link to comment
