@atmasphere I thank you for your input. I prefer Balanced AES48 but unfortunately not all component manufacturers subscribe as you do,. So it is a game of compromises. I am using an unshielded RCA from DH from my phono section to my pre, noticed a more open sound from the shielded RCA I had in place.
So I must ask as a mfr of both tube and GaN amplification what have been your experiences and are their brands and types of cables you prefer. I do find that the WW Mini Eclipse 8 speaker cables work very well on my tube gear and they are only 5 foot lengths, great buy from The Cable Co for $360.00 vs $600.
