That would have been a good price for the 4800 but very mediocre for the 3800.Denon website price is $1,459, not too bad.

Denon AVR-X3800H Review
- Thread starter amirm
- Start date
I tried running the A1 Evo Express script on the Cinema 50, and while it looked like it worked, the results were almost the same as having no EQ at all. It doesn’t seem normal, and the sound quality wasn’t good, so I can’t really evaluate it.
All I did was press Enter a few times in the initial steps, but when I changed the value from 8 to 3, it measured the same position three times.
I also couldn’t figure out how to perform multi-point measurements.

Maybe it is the TARIFF factor?
About CAD 100-150 better now in Canada (based on Denon Canada's price) based on the relatively low CAD worth in recent days.peng, here are the mdat files for RC, BC, and ART.Maybe it is the TARIFF factor?
I also measured at a position far to the right of the MLP and slightly higher.
I didn’t measure with the A1, since it didn’t seem to be working properly.

Aside from cutting that peak at 50 Hz, it seems to have done nothing. With two subwoofers, it should've at least been able to fill in those nulls at 100 and 160.
Excellent results, thanks. Anyone can say xyz is the best, but words don't count that much, measurements do. Wonder what went wrong with the A1 Evo Ex one?
Well… simply pressing Enter doesn’t seem to work properly in my environment.
Doing any further testing is a bit too much for me right now.

Don't think it'll get much better. Maybe some local shops will have better deals and/or cashback, but otherwise if you can't/don't want to wait

Class A Audio actually had it for $1749 back in Jan, which I got them to match a couple of weeks ago. Still sad that we pay so much more than some of the best US deals, but looks like this actually might be competitive given the current tariff situ!
It seems you have more serious problems than the choice DSP. 10dB boosted treble? Massive 50Hz wide 30dB dip only on the right speaker? There's something wrong with these speakers, no placement can boost HF like that and placement seems to be obliterating the right speaker's bass response.Well… simply pressing Enter doesn’t seem to work properly in my environment.

Anyway, absurd HF response has caused the target level to be set higher than it should normally be and bass is EQ'ed not as low as it should but otherwise these distance settings Evo has set seem perfect and will in no way sound horrible:
17:04:54[FL] 2.75m (9.02ft)
17:04:54[FR] 2.86m (9.38ft)
17:04:54[SW1] 7.70m (25.26ft)
17:04:54[SW2] 7.88m (25.85ft)

This is a pair of JBL 4425 speakers, and they are not broken.
The dip in the right speaker is simply caused by the room.
It seems A1 Evo Express malfunctioned a bit due to the slightly strong high-frequency response.
Here is the frequency response after applying Dirac correction up to 200 Hz and fine-tuning the sound with manual PEQ to match my preference.
You cannot do much in Express although I know people who hack it and change target curve during the optimization process. You would need a target curve with that 10dB HF boost for Express to get the target level right as it determines levels based on their midrange/HF response not bass response (this is the right way). But I insist that the HF response of your speakers are nothing but normal. It could be a broken mic, mic angle or a mic calibration file issue during measurement. The natural tilt caused by room reflections is in the opposite direction for almost every set up. Acoustica has custom settings including target curve selection and crossover range selection (which your right speaker seems to need) but better wait for the new Evo (AcoustiX) which has all sorts of custom settings to fix such local issues and it's coming very soon:
How did you do the manual PEQ? Dirac doesn't do PEQ, so did you do it on the sub that has its own PEQ/DSP or something else?
Yeah, I think such custom settings to shape the target curve would be a huge step for people like me who likes pretty actual REW FR graphs regardless whether it sounds better. To get the actual FR graphs to look good, the target curve may (in my case anyway) may have to look weird, ugly, to me such ugly TC that looks like bending out of shape would work like a manual feedback loop to the RC/measurements such that if the RC (example A1 Evo) still shows a bump of 5 dB at 50 Hz when the TC is flat there, then it could be due to incorrect measurements, mic positioning, weird room acoustic characteristics etc., then I could put a dip of 5 dB +/- a couple dB to force the final FR to smaller or 0 bump there. I worked for me this way when I used Radbudyssey with the $20 MultEQ Editor app. At the time I told Audyssey about the feedback/error correction concept, at first the rep/agent debated me a little but towards the end he seemed somewhat receptive, then months and months later they launched the $200 app and in their training videos in which they seemed to have accepted the concept (to some extent I assume because with that app, one can customize the TC quite easily) with that there is nothing wrong with bending the TC out of shape in order to get the actual FR in better shape. Dirac is great in that regard as the TC can be shaped to just about any form as well.
An extreme exaggerated example (a perfect RC/EQ system and a reasonably well behave room/subs) would not need that) of a crazy looking TC, that worked to produce a near flat REW FR in that range:
If AT let me customize the TC to that, it would work for me
I’m applying the following manual PEQ using Equalizer APO or Roon.
The subwoofers are DIY passive UM12 units.
As long as I let Dirac handle the low frequencies, I don’t need any additional DSP.
It seems that getting good sound with Dirac is easy, even when there are many variables.

This is quite a healthy EQ given the very low Q factors but I am not saying it cannot be EQ'ed. I am saying there's something wrong in the in room responses, this cannot be the natural in room response of a descent speaker certainly not of a JBL. 4425 but it's your system, your taste so I will shut up.

I add a house curve specifically for music when listening with Roon. It's a great feature.
It’s just an ordinary, slightly small Japanese-style bedroom, and the listening distance is about 1.5 meters.
Here are the Dirac MDAT files measured at the MLP and at an off-MLP position (with no PEQ applied).
If your auto-EQ can easily handle environments with this many variables—such as vintage speakers or
DIY passive subs—then it truly has the potential to become an excellent system.
By the way, I’ve tested many speakers in this bedroom — Sierra-LX, UBR62, HDI-1600, and LS50 Meta.
Among them, the 4425 with PEQ applied is the one I like the most.
In my JBL room downstairs, I have four more 4425s, and they show very similar characteristics.
There, I insert the PEQ between the AVR pre-DAC and the power amplifier.
