Just an update... as I typically don’t like open ended threads ha.
bought a denon x4500H and it’s a beautiful beast of an AVR.
plugged in two matching atmos speakers as well.
sound quality after setting up the denon and running their auto tune setup. Is pure bliss. No sub is connected so far and I’ve never been more pleased with the sound quality. Still adjusting the front L/R speakers. But love this setup.
I thought you like the gorgeous Marantz?? You made a good decision if you don't worry about those 8K stuff that likely wouldn't work anyway by the time it gets popular. You also made an excellent choice going with Denon in terms of sound quality related specs. Whether it is audible or not, you can at least feel good that the Denon should have much better measurements in THD+N, IMD, among others than the SR7013, because on bench tests of similar models. I own both and like both, but there is no denying that Denon's team if more objective in not bothering with the redundant HDAM modules that in theory would do more harm than good.
The only thing I would suggest now is, give room EQ another chance, you may be surprised how good Audyssey XT32 is especially if you have two subs, one on each side, and use the Editor App ($20 download) to limit the EQ frequency to about 600 Hz or lower. And use DEQ as ADTG suggested before, if you don't listen very loud.
It's kind of doing this backward, but I'll be curious to know if you are giving those big Klipsch the juice they need. My guess is, you are, but to be sure, would be great to see your results with the calculator below:
Just a few notes though:
- When entering speaker sensitivity, whatever the Klipsch spec sheet says, subject 6 dB, e.g. if it is 98 dB, enter 92 dB instead.
- For no. of speaker, just enter 1 for now.
If you report back the result, I can tell you in high confidence level that whether you need an external amp.
In any case, sine you mentioned you want you new AVR to last for a long time, then please product your >$1,000 new asset, with a $11 fan. Just put one on top if the AVR has the recommended space to vent, if not, put two. You can't rely on the build in fans because by the time they kick in, longevity might have already taken a hit.
