Sinad

[Klint]

Hello

I have been looking at the Sinad explanation in the forum and get it, can calculate back and forth, i am an expert.

But, what does it mean, how do i notice difference.
Looking at miniDSP HSD and NAD C658.
The miniDSP is maybe ok with 112dB.
The NAD is not good t all with 90dB.
I have a Marantz AVR 7015, completely useless with 80dB.
Just cant seem to pinpoint the uselessness.

Has anybody got an explanation to where one would hear this.

In a word, no.

Sinad is a composite figure which includes both noise and distortion, which are very different issues.

Neither is a problem in the quantities even your 'completely useless' Marantz AVR produces.

But, what does it mean

I rest my case

But seriously, your not bound to hear anything. Check out one of these threads with multi percent distortion added to music and have some fun

but what is important is that you can see how transparent your device is. From 96 on it’s fully transparent for CD quality audio, so 16 bits. You will never have 24 but transparent system, since the laws of physics are against us there. For DAC’s 20 to 21 bits is doable. For amps that is very rare.

Don’t get started on speakers. They would have a very bad SINAD score (obviously dominated by distortion)

As pointed out, it is a combo of noise and distortion, so it depends on your audibility of each.

Amir has stated that ~116dB is where he can bet his life that it is transparent for everyone.

100dB would be enough for most everyone, and for sure if not doing A/B comparisons.

Even 80dB should sound fine and be a non-issue unless doing A/B comparisons.

Thanks guys.
I found this forum and finally found a place where science could tell me what is good enough.
Away from "listen to this one, only 1000euro more, do you here the....blabla."
I have only been able to here differences with speakers to be honest.

This was helpfull +100 and its a good product.

I would like to say that a little bubble within high end is bursting.
The really best products, now cost a fraction of what has been said to be the best ones.
