Did Amir Change Your Mind About Anything?

It’s easy to make snide remarks like “yes- I do the opposite of what he says.”  And in some respects I agree, but if you do that, this is just going to be taken down. So I’m asking a serious question. Has ASR actually changed your opinion on anything?  For me, I would say 2 things. I am a conservatory-trained musician and I do trust my ears. But ASR has reminded me to double check my opinions on a piece of gear to make sure I’m not imagining improvements. Not to get into double blind testing, but just to keep in mind that the brain can be fooled and make doubly sure that I’m hearing what I think I’m hearing. The second is power conditioning. I went from an expensive box back to my wiremold and I really don’t think I can hear a difference. I think that now that I understand the engineering behind AC use in an audio component, I am not convinced that power conditioning affects the component output. I think. 
So please resist the urge to pile on. I think this could be a worthwhile discussion if that’s possible anymore. I hope it is.

First of all, how dare you classify me as "you people"? 

????

Never mind. 

 

You cannot return a bit of repaired audio kit without first proving you've eliminated the reported problem and ears+brain are insufficient

It's not about repearing faulty components and listening to them afterwards. That mean's nothing here. 

1- Have you compared quality components and speaker/interconnect/power cables from known brandd in AB tests and what were your findings? 

2- What if a product promoted by Amir or by you doesn’t sound good, should I base my desicision on my ears or your measurements?

3- Do you believe that components/cables with identical measurements sound the same?

1. SPDIF must use a coaxial cable.
2. SPDIF characteristic impedance of the cable must be 75 Ohm
3. SPDIF cables are often orange
4. It's a digital signal and as long as the cable is well made, there should be no difference in errors and so no difference in sound

I personally like #3 😉

As long as 1 and 2 are observed the colour is irrelevant, of course, But some manufacturers seem to colour code them so people don't accidentally plug them in the wrong hole. It's not the case for all kit I've seen, but I've bought three digital products which were shipped with an orange cable for S/PDIF in the box. Perhaps it's an EU thing?

It's a real pity S/PDIF uses Cinch/RCA, since BNC would have been better and less prone to mistakes.

S/PDIF is just a protocol. It can be used with RCA, BNC, or optical connectors.

Absolutely, but most manufacturers have utilised RCA, and there is always a problem if a manufacturer does use BNC: people would complain that their other kit is RCA and they have to use an adaptor. So marketing would wonder why the engineers have picked a technology that annoys customers!
