@twoleftears The new production Gold Lions respond well to cryogenic treatment. I use GL 12AU7s in my line stage on an ongoing basis and replaced the stock Sovtek 5AR4 rectifier in my SACD player power supply with a Gold Lion GZ34. I always source my GL’s from Cryoset. Ron Sheldon’s tubes are quiet, neutral and seem to last forever...they just don’t get noisy.
One more tweak that really makes a difference is using Herbie’s Audio Labs tube dampers on ALL tubes. I just got an all titanium damper for my very hot running GZ34. It fits tight as can be and as crazy as it sounds all images since installing it are rock solid. Greater air to soundscape and improved dynamics!
