Channel separation...how much is enough...how much is not?

5db - 10db

Is that true? Could be about right but would depend a lot on room and distance from the speakers I would think?

That came from Edgar of Theoretica. He’s one of the few people who has extensively measured it with in ear microphones.

You have channel separation and crosstalk. Crosstalk may be either L into R or R into L or both. And that crosstalk is usually proportional to frequency, but not always.

How much separation does our head and ears really have anyway when listening to loudspeakers in a typical room?

What's your point?

I will posit that 30 db or more channel separation is enough. More than that is not audible. In fact 17 db or so is enough.

So why is a device with only 70 db of channel separation described as "poor channel separation"? Poor versus what is possible? Yes. Poor versus what is audible, not in the least.

Poor design.

Poor design.

Why?

 

[Koeitje]

Why?

Because its elementary to hit decent numbers. If a piece of electronics doesn't hit that it means the designer paid absolutely fuck all attention to the design.

But decent values are below audibly threshold. Say 70 dB. Doesn't mean they "gave fuck all" but rather that further enhancements are inaudible.

A lot of us would rather have a Ferrari than our current vehicle as well, so the reason for channel separation exists ... Somewhere.

Agreed.

Channel separation is also the excuse audiophiles give for monoblocks. Once again, that seems bizarre.

I can argue with you on that, but it would be besides the subject matter.

My take. By principle a channel that bleeds to another channel is added distortion. Stereo signals are however partly correlated so it would in most cases not be audible below 20-30 dB. But there would probably be some examples that are audible below 30 dB.

That's a cowards reply, that! Is your point not related to channel separation?
