The 2600 may have been the greatest stereo receiver ever commercially produced. It could deliver 400 wpc into a 4 ohm load across the audio band with both channels driven.

They easily outperformed most separate power amplifiers of the day and they could probably still do the same today. The preamp and tuner stages of a solid state receiver require very little power and generate very little heat so in well designed receiver, there doesn't have to be any compromise. Most companies build their power amplifiers today on separate chasis as a marketing strategy, not for technical reasons. In the long ago past, the need to place two huge output transformers along with many hot vacuum tubes on an acceptably sized chasis made high end receivers impractical. With miniaturization and solid state electronics, that is no longer true.

I have my father's Marantz 4400 receiver with the SQA-2B decoder. Good ol' quad sound. It's a beast. Worked perfect until about 1 1/2 years ago. Sucker won't turn on. I have been meaning to get it into the shop. I will probably sell it at a later date.
