Best Receiver?

Krell 300r.

I have two suggestions based on my experience - The first is my MAC6700.  250 watts per channel and a really nice DAC, analogue inputs and beautiful sounding 250 watt McIntosh amps inside.  I use it in a hybrid home theater setup where I use Passthrough mode to power the main L and R of my home theater system and I couldn't be happier.  I do RARELY use the tuner, as my streamer has "Tunein" radio which is a streaming app that pulls the digital signals from my local stations and also a ton of radio markets across the country.

And this will be controversial here - but I just got an Onkyo RZ-50 for my living room and - WOW.  Brilliant for home theater and really, really nice 2 channel as well.  DIRAC needs to come standard on more two channel or 2.1 systems in my opinion.  Huge benefits.  

Happy shopping! 

I have a Marantz sr5006,Pioneer vsx80,Yamaha rx-a3070 and a Anthem mrx-540.I use all of them accept the Marantz because I don’t have enough speakers.Anthem sound the best.It has a awesome calibration system.

Years ago, I had a Pioneer that sounded good; It looked good too with wood sides. It finally burned out and I replaced it with a Harman Kardon that I'm really fond of. I still use the Harman Kardon today to drive my Altec Lansing Voice of the Theaters. This has turned into my secondary system although I cannot fault the sound. My primary is Conrad Johnson with Theil speakers, also very good sound.
