too much bass, too heavy sound

My Nap 300dr sounded wonderful for the first month it is played 6 or 7 hours a day,the second month was strange sounding terrible at times it took well over 3 months to settle down and behave so it could still be breaking in wait till your dealer listens to see if he can advise and sort.

When it is right it is something very special indeed.

did you have also this too much heaviness, bass in the sound during your second month?

Yes the bass did go a bit off but also the treble went very screechy rather off putting to say the least I assume you 300dr is left permently switched on ??

Have you recently installed software v4.6 on your NDS? If so that may be the reason the sound has gone off.

My nap500 increased its bass energy when run in .... had to reposition speakers....

since a few days my system sound had become too heavy,

that occurs due to mains noise, might be exacerbated by third party devices, if there are any in the system.

the bass is less heayy a few minutes a day.

My system is quite different from yours, but I do have a NAP300DR. It’s new but it’s been playing for ~320 hours (almost 24h/24h). The sound was a bit harsh during the very first minutes, and then improved drastically after ~48 hours playing. It now sounds amazing, and still improves but nothing glaring.

But, I can’t really say if the above is directly related to the NAP300DR only, as the whole system is new (252/SC-DR/300DR).

You haven't burnt out a tweeter, have you?

My 300 took months to settle down. It wasn't a case of becoming accustomed to it because things like ringing and chuffing squashed DR are not mood dependent. If the bass is setting the room off, its unambiguous.  If you can't follow a bass line or a vocal that was clear yesterday, something has changed and it (probably) isn't a sudden loss of hearing  ability. I did a fair bit of speaker tuning, although I'm not entirely convinced this had more effect than waiting a few months for the sound to become consistent, then doing the last of the tweaks. 

Regardless of run it, I also had big issues with what I believed to be mains quality, which did seem to vary predictably throughout a listening day. This persisted with the 500 and stopped when I had it DR'd. Coincidence?

Another thing I experienced with the 300 and 500 was a gradual slowing down and loss of dynamics. Nothing huge but that last, essential facet of magic could go a bit flat. I would power down the NAP and restart after 3-5 minutes, as necessary. Probably every 2-3 months. I haven't needed to do this since the 500 was DR'd. So I might have  been onto something. Possibly.

yes, always switched on.  But i finally found the problem:  i put out the finite elemente cerapucks that were under the 300, and the magic returned!  i put these cerapucks one week ago, but was not thinking of them and has even forgotten that they were under the nap 300...

It was just that:  the cerapucks were increasing the bass and heavyness too much. 

Heavy bass and room resonance... I don’t think it’s a power amp as such.

More likely long bass waves getting trapped in the corners of the room or some odd room resonance that wasn’t so pronounced before. Have you added some furniture / taken some away / added or removed a carpet etc?

Can you try one thing?
Take some cushions / rolled up blankets even a duvet and stuff them in the corners of the room just to see if the bass gets under control. It’s not a permanent solution, but it will help with a diagnosis.

We use this method when trying to tame my bass rig in our rehearsal studio

thanks for your support. As i said just before, i had put one week ago the finite elemente cerapucks under the 300 to test. I don’t know why but i forgot about these cerapucks...

I put them off a few hours ago and the sound is much more balanced, without this heavy and too bassy sound that was vibrating all my room.   Perhaps in bigger rooms these cerapucks can be positive on some systems under the nap 300...

Under my speakers i have finite elemente cerabases and it is a very positive contribution.

So entirely self inflicted, bit of a coq up in fact.
