In the world of science we are learning new things all the time. From Quantum Physics to Astonomy to medical discovery among many fields things are happening. There are all kinds of things that are not fully understood. Don't deny yourself a chance to participate just because the "facts" haven't been able to measure everything in audio yet. Experiment. Listen. Try cables, suts, other things, be open to discovery. Don't be afraid to be wrong. Explore. Discover. Have fun. Accept no limits. What you think is known is expanding all the time. Be part of it. Don't be afraid.
SUT experience
I finally went the SUT route for my TD124/SPU combo
II wish I would have done it sooner. I was using the phono input on my McIntosh C47 preamp for the last 3 years and was satisfied. Yesterday I added a a Japanese Entre T100 to my system and was very surprised. Many of you will already know but I’m new to the SUT game and it was a game changer.
