Respectfully, speakers make a bigger difference in the final “color” of home audio than any signal component. They sit at the end of the chain and actually create the sound waves you hear. Peter Comeau is my sonic reproduction guru and his big baffle work for IAD’s Brit brands is music to my ears, literally.
With some great advice from the discussions here on vintage pro audio gain, cabling, DAC specs and WiFi streaming - my AE Techron serviced Crown PS 200 drives Wharfedale 85th Anniversary Heritage Lintons and a speaker level output REL T5i with non fatiguing perfection :)
Long story short (too late, right) I found that the pursuit of listening pleasure can reach an actual end point in signal resolution if you like and understand your speakers. It’s all about moving air when things are said and done.
