Blind fold hearing test

No I couldn’t. But...
- I could probably identify electrostatic speakers from any other kind.
- I’d have a fair chance of separating most valve amps from transistor amps.
- I could definitely tell if TC and/or mats were in use in the system or not.
- I could tell if adequate vibration damping/isolation was in place or not.

It would also depend on the hour of the day. I could make much better judgements after 12 midnight.

Everything sounds different in different rooms and in different systems. Thus, you won’t be able to figure out what speakers, what amps, what cables, etc. you’re listening to if you were blindfolded.

The corollary of that statement is you cannot foretell what a system will sound like by knowing what components or speakers or cables are in the system. Nor can you tell what a system would sound like by looking at a picture of the system and the room. I’m afraid, gentle readers, those are all old wives tales.

No way!Maybe type of speaker or amp but not specific brands.

This is like asking what camera a picture was taken with.  People spend all kinds of money on different camera bodies, but most people wouldn't be able to pick out a shot taken with a cell phone vs a $5,000 DSLR and few if any could say that image was created with a _______ camera.
