Sound of AVR vs. separates

Hey guys!

Probably a silly question - but I am thinking of swapping my Marantz 7011 to the 8802 - I'm currently using a Krell Chorus 5200 amplifier. I have thought about waiting a bit and going to a McIntosh or something similar...

So, here's my main question - will there be a noticeable difference in sound if I swap to the 8802? Or am I just upgrading to have better gear, and having separates w/ dedicated functions? I will have to wait a bit to get a high end processor, but I'm curious if this switch will imrove sound in any way...whether it be sonic signature, volume, clarity, etc.

Thanks again - I'm still  learning all this stuff! Oh, using ML Ethos as fronts, and I am mainly movies and gaming, about 15% (and climbing) for 2 channel music

@ethos4lyfe - have you tried upgrade the Oppo 203 firmware?  I see the following items in the last 2 firmware releases.


Jan 20th release
- Resolved an HDCP 2.2 failure when connecting to an HDCP 2.2 receiver and an older, non-HDCP 2.2 display.
- Resolved a black screen issue with certain UHD titles after resuming playback.


Feb 27 release

- Resolved a black screen issue when streaming 4K content via the player's HDMI In port from Roku and other 4K streaming devices.

Try connecting your Oppo or PS4 directly to your display (completely bypass the Marantz receiver).  See what 4K modes will work.  It could be similar to your Oppo/PS4 not being able to query the final display device for HDCP2.2 / 4K compatibility, like this Oppo bug that was fixed:

- Resolved an HDCP 2.2 failure when connecting to an HDCP 2.2 receiver and an older, non-HDCP 2.2 display.

I'm just grasping at straws here, as Bob indicated it could be new encryption compatibility/communication standards.

Sounds like you got a defective HDMI transceiver/board in the Marantz.

What kind of HDMI cable do you have between the Marantz receiver and your display device.  How long is the cable?  If it's a really long cable, it could be clipping the square waveforms.  What kind of display device. 

I have had issues in the past when new HDMI specs come out and I needed to replace my cable.  In your case, it could be a bandwidth issue for 4K.  The communication between Oppo and Marantz is fine because you are getting sound.  However, communication between Marantz and the display could have problems caused by an inadequate HDMI cable.
