Yes,the Sherwood/Boston avr's are basically the same box and the large heat sinks are on the far left and right from front to rear.They have a monster power supply for avr's and the box looks full in the avr version.That said for some reason they sound NOTHING like the 990,even as prepros.I was amazed how poor these avr's sound,plenty power,great build,sound was congested and almost unlistenable.Any HK/DENON etc would be superior in all but the build/power,ALL imo.
