Anybody want a laugh?

I can only assume you don't understand blind testing mahgister. The only requirement for blind testing is that you don't know what you are testing. That is it. That is all. You can take second, minutes, hours, days, months to review or make  change, the only requirement is you don't know what was changed.

Yes i understand that.... But for me to increase the positive change i must know where and how and what i have done... At the end the change is so great and big, i will take the blind test.... It will be easy to win , but in my house, with my file, otherwise how can i?

To implement the test it will takes a day just to erase all the tweaks...

Another day to make them in place anew...

Oufff All that for what?

Blindtesting a cable is easy .... Blind testing a system less easy....


My point is precidely that: blindtesting a stream of successive incremental changes has no interest at all....The end result is not equal to a change in cable.... :)

It seems it is you that dont get my point without being rude....

Audio does not reduce to what you think it must be ....

In the 21st century audio engineers build equipment while actively avoiding two of the most powerful tools available to the whole of science and engineering: measurement and error control. The damage to the audio industry and its reputation in the wider engineering world will remain immeasurable until we decide to take control.

His amplifier designs and the THX AAA circuit topology are really the only unique things happening in the HiFi world worthy of note recently, imo of course. I also feel the need to push back aggressively on the preposterous assertion by a few people in this thread that “streamers” are somehow better than a PC based front end, with zero evidence of any kind being offered.
The way I see this development is simple, I’ve been using a PC front end for 20-years, it was simply too difficult for the median age audiophile to assemble their own computer, configure the software, download the FLAC files and on top of that, there was no opportunity for you guys to get out your credit card and spend thousands on a shiny new box and get that dopamine hit. Some of you might take offense, but I’m sorry, streamers aren’t doing anything new, and they certainly don’t sound better in any demonstrable way than a middling PC setup connected to a good asynchronous DAC.
I use a USB DAC with 116db SINAD specifically to ensure that my front end is outpacing the amplification it feeds in terms of noise floor. I know measuring things is frowned upon here, but I generally roll my eyes hard enough to do a mental backflip when people say things like Ethernet or WiFi is superior to async USB.. Based on what?

But for me to increase the positive change i must know where and how and what i have done

The it isn't a blind test. A blind test and passing would be removing one thing without your knowledge and you can tell a difference more times than chance. 

My counter dougeyjones to the USB, is that the USB is competently designed and properly isolates the USB from the output including the potential to pass on EMI from the computer through the ground connection on the output to subsequent equipment. That even happens in lab equipment, let alone audio equipment. The higher
