I am running 5.1 system using Pioneer SC55. Watching TV, Movies, Music.

Center - Sierra Horizon (RAAL)
Left/Right - Sierra 2EX
Surround - Old Pyle in wall speakers.
Sub - PSA Audio F15SE.

I have no issues with the setup. I guess soon its time for a AVR upgrade. Here are the options:

Option1: Keep the Pioneer SC55, add an external amp, and upgrade the Pre later
Option2: Buy another AVR.

A couple of years ago my AVR stopped working with ue22 error. Onkyo fixed it for free.


Option1- Emotiva XPA5, Outlaw5000x, Monolith
Option2 - No idea yet

The equipment go into an enclosed space. For the airflow, I can open the door of the enclosed space, otherwise, no option. I never had any heating issue with Pioneer SC55. Nothing will be placed on top the the new equipment with at-least 5 to 6 inch of space above.

Thanks for the suggestions!
