REL Carbon Special. Replaced a REL S/510 for no particular reason other than opportunity. Soon as I set it up, I had a WTF did I just buy moment. It’s a beast and I thought for sure it would be too much for my room. Turns out that it’s absolutely fantastic. Zero regrets and I’m loving it.

Small Green Computer optical isolation bundle to clean up the ethernet cable signal from wifi extender to streamer. Subtle improvement, nothing major, in clarity and sense of space. For $350, it was worth it to me. Probably similar improvement to etherregen for half the price and in stock now. However have not tried etherregen so don't take my word for it.

Just received a new power supply for my Node N130. It made an immediate difference and a couple of days later I changed the power cord going to it and that made a further difference.

Don't know how high-end it is considered, but I just bought a new Audio-Technica AT33SA moving coil cartridge last week. I am at the 20 hour mark of the recommended 30 hour burn-in. When I first got it set up and started listening to albums, it sounded a bit thin. As the hours of listening increased the cartridge really started warming up nicely. Right now I am happy as it is sounding really nice. If it sounds better after 30 hours, then that is just a bonus!
