What is the sensitivity of your speakers?
How big is your room?
How loud are you playing?
Your amp has 500 WATTS at 4 ohms!
Why would you consider inferior products as replacement?
What do you have for A/C electrical isolation and power conditioning?
In my experience Burmester fed clean power should not get brittle and compressed.
Summary: I think you're looking in the wrong area.
I would look at the amp sensitivity and the Exogal output.
Hope this helps.
