New receiver

.... otherwise very good sounding Arcam, NAD, and B&K receivers but, again, NO EQ feature! (basically all rooms have bass problems you'll not fix from 20hz -300hz, and REQUIRE EQ'ing, PERIOD! ..too invaluable to pass up for hi-fidelity, IME).
You (he??) doesn't need 7.1 or Atmos, etc? Any 5.1-7.1 that fit on the list, are worth investigating, find reviews, or must give a try or sell if don't work out for you. Ok, I'm done now. ..

I have a Denon Avr 3100 and love it.

The all in one box feature is for this guy. A couple of people have recommended Denon either the 4200 or 4100 or the 3100 series. Seems like they are all pretty similar. Higher numbers more power and better Audessey and now HDCP 2.2. Do we need this? How do the Denons stack up against the competition. Thanks for all of the responses.

Denon used to have better quality control at lower price points, IME. But Denon's overall stand-alone sound quality is still a pinch better At all price points, though. What you do get is more amplifier power and features on Onkyo's, dollar per dollar.
If however, I was buying off shelf today at $1000, I'd say I'd probably still have to get the Onkyo. (wow I can't believe I said that! ..I'm disappointed in you Denon!)

For the record, Just stating, that a few years old HK or Yamaha AVR with features needed, add some used Parasound HCA1205a 5 ch power amp - all for $1000 range, used, total - and would most definitely stomp on the sound quality of the $1000 stand-alone AVR, new!!! Yup, pretty much hands down. Just saying... I'd rather have superior sound quality/performance, myself.

$1000 new Denon/ONkyo = 6-7/10 sound quality,all considered
$500 (used) AVR(w EQ)+amp = 8-8.5/10 sound quality

I am quite impressed with the sound from my Onkyo TX-NR809>Krell amp setup for two channel sound.
