HOW TO IMPROVE YOUR SYSTEM IN LESS THAN 30 SECONDS
I am serious. I work VERY hard to have the best system I can. I have made many upgrades and am more than happy with my equipment. I stream 100% of the time, mostly form Qobuz. My digital front end is highly optimized. But when I want my system to sound AMAZING?
I play Mark Knopfler or my favorite Dire Straits. Seriously. It is recorded so exceptionally well, and seems to have harmonics which just please the ear and soul. I often think it sounds a bit 'tube like', as my system is all solid state. There are just no offending sounds, and never sibilance. I could list songs, but it would be easier to just list the one not to play ('Money for Nothing').
