What’s your latest high-end audio purchase?

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!

DCS Rossini Apex and Rossini Clock. I upgraded from the Bartok. There are layers of detail and nuanced dimension that I’ve never heard in familiar music. Live recordings are blowing my mind with stadium “being there” moments. The pedals in the piano - Jimmy Paige’s vocals on “Kashmir” at the O2 - Blood Sweat and Tears first album sound gorgeous. Zero fatigue - Worth every penny. It really compliments the ARC REF 6, ARC 160s and Sonus Faber Serafino’s. I love it…!

I upgraded my Linn LP12 table from a std sub chassis and Akita arm to the Keel and the Ekos SE arm. Really nice upgrade, increased the level of detail and transparency. I really love the way one can cost effectively move step by step towards the top-of-the-line. Great product!
