    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    I checked the analogous impact of adding a subwoofer in the settings Denon AVR-X3600H on my subjective listening experience. This is again without adding a physical subwoofer and with all speakers set to full range. There was also a bass reduction, consistent with the behaviour of the X3800H...

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    I believe that I found the cause and a potential solution. Adding a subwoofer in the speaker layout settings (without actually adding a physical subwoofer to the setup) appears to fix the issue. This is without applying any crossover, i.e. all speakers set to 'full range' before and after this...

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Thank you. The perceived differences described in my original post are apparent both pre-calibration, with Audyssey and in Direct mode. The description of the impact of different correction software choices was meant to illustrate the extent of the bass issue. Apologies for not stating the...

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Thanks. Audyssey involves moving the mic around which seems to make it impossible to recreate the exact same spots, no? I am sceptical that the issue arises at the calibration level. The bass difference between the 3600 and 3800 is clearly there pre-calibration. Audyssey's `chirping sounds with...

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Thank you. I have attached screenshots from the Audyssey iPad app for the front speakers with both receivers. Everything else in the setup is the same between the two measurements.

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Yes, I have, in both receivers. Regarding posting the Dirac curves, thank you for offering to 'diagnose' them. I do not have them available at hand, and I would rather not post them at this early stage of the thread anyway as to not drive the focus away from the AVR issue with large...

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Hello, Apologies, I am not sure that I follow. The only difference between the two systems is the Denon model used as a processor. I have used the same Hypex amps both with the X3600H and the X3800H.

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Thank you for your input, but the issue is not isolated to Dirac. The overpowering low frequencies are present straight out of the box pre-calibration, in the Direct mode post-calibration, and with both Dirac and Audyssey. Dirac's default curve yields worse results as it boosts the low...

    Denon AVR-X3800H sounds bass-heavy to my ears and markedly different (worse) than the subjectively flat AVR-X3600H - why?

    Trigger warning: this thread will be full of my subjective impressions. I would like to understand why I am hearing what I think I am hearing, if there are any solutions to make Denon AVR-X3800H work for me, and if my listening experience can be reconciled with the ASR's test results. I hear...

    Expected voltage on binding posts of NC252MP

    Thank you. Just to clarify, this was a used amplifier - not bought directly from Nord. Just to emphasise that there is no suggestion of any fault from Nord per se.

    Expected voltage on binding posts of NC252MP

    Thank you very much, again. With the multimeter set to the 20k ohm position, I was able to get a reading of 2.60, and I believe this is in kiloohms. I gather that this is far off the expected value. Can you please explain what this means? Thank you for doing the math for the watts. Does the...

    Expected voltage on binding posts of NC252MP

    Thank you very much! I got the caps and have the results. RCA and XLR results refer to the switch position at the back of the amp and, if applicable, use of either XLR-RCA cable (Monoprice) or RCA-RCA. The source inputs were the RCAs on my AVR for back surround speakers as I had them sitting...

    Expected voltage on binding posts of NC252MP

    This gets me as far as knowing that it is my amp that I don't know what to do with. :) Can you please tell me what specifically I need to do? I am not familiar with the term. Further googling with amp terms gets me as close as having a guess that it involves connecting inputs with one another...

    Expected voltage on binding posts of NC252MP

    Thank you. I tried my best googling around 'testing with the inputs shorted', but I could not figure out what you meant. Can you please be more specific as to what I should do with my multimeter in hand?

    Expected voltage on binding posts of NC252MP

    Hi, I just got a hold of a used 3-channel amplifier based on NC252MP. As advised earlier on this forum, I tested it with a multimeter before hooking it up to speakers. I am getting 0.29 volts on channels 1 and 2 and 0.4 on channel 3. Upons switching off, the voltage goes up to 1.3-1.4 V for a...

    Can a faulty amplifier blow a tweeter or a woofer just by being turned on?

    Thank you, all. Things are getting weirder and weirder. I thought it might be a good idea to swap the woofers to see if the one previously under suspicion of being faulty would play fine in the other speaker, which it did. As I opened the other speaker, I noticed that the insides of the woofer...

    Can a faulty amplifier blow a tweeter or a woofer just by being turned on?

    None at all. My local audio dealer works with a reasonably priced repair centre, so I will pass this on to them. They already started sourcing a replacement woofer, so I will update them on the diagnostics and they will take it from there. Going back to my Loxije A40, should I still get it...

    Can a faulty amplifier blow a tweeter or a woofer just by being turned on?

    Thank you guys. I am getting again 0.1 ohm readings after falling down from initial larger values when touching a speaker binding post and a wire previously connected to the woofer. This works only when going for the same colored post and wire. Otherwise, there is no reading available. So...
