Are the three a lot different?(perceptible difference)
Description says they differ by their filter resolution but I want to know whether it actually means something.

For me, in my non-optimal room, the difference between my old Denon 3808ci that had XT vs. my current x3400h that has XT32 was night and day. XT32 has vastly superior ability in correcting the bass region especially.

From what I've seen of comparisons, I would not buy anything without XT 32. The others just don't do anything useful. Here's a comparison of corrections from AVSForum, you can see XT does practically nothing in bass.

What am I missing there? The XT is in blue and XT32 is in red/green right? The blue line seems more smooth below 500Hz, almost to the point of seeming like there is more smoothing of the data. But above a few kHz it almost seems like the data is less smoothed.
Sincerely, Confused by that Data.

The graph is the corrections made by the software -- not measured speakers. Note at the top it's labeled "Center pre-out" -- what was being measured was the output directly from the AVRs.

Yes, I definitely thought that was final result e.g. speaker out.
Ah, so this is the filter compensation, so no correction would be flat at 70dB? Or at least that roughly looks like the average to me.
It also seems like XT is kind of making a mess of things in the high frequency area too; making a bunch of very small very high q corrections. Which is what MZKM was saying.

Correct, there's no situation where that MultEQ XT bass correction would be useful. Everybody has some significant dips and peaks, even if you have 4 subwoofers perfectly placed. And yes, the high frequency correction is crap too. MultEQ XT does basically the opposite of what is useful -- low Q, slight corrections in bass, and high Q in the highs.

Amir reviewed MultEQ XT 32 with the app here and you can see it produces good results.

Do you know about the difference between MultEq and MultEq XT?

I have never seen a test of the basic MultEQ. Given that XT does hardly anything useful(maybe even harmful) and the MultEQ filter resolution is even worse based on the table above, I would say MultEQ may not even be worth enabling at all lol.

So, why waste the time "testing" it at all?

Agree, I don't think there is any point testing basic MultEQ. I was just saying I hadn't seen one in case of any followup question asking for data. :)
