Part 1, Welcome to 300 Hours of Summit 300B tubes.

Enough with the short reviews. Dive into the unhurried world of tube rolling with Part 1 of my 3-part series on Psvane 300B Summit tubes. Forget rushed reviews—this is for true audiophiles who savor the ritual. I unbox these beauties, bias them gently on my DIY 300B single-ended amp (with open-baffle Lii-Song speakers and a killer R2R DAC stack), and share raw first impressions after 10 hours: hyper-detailed highs that intrigue but distract, evolving with fatigue vs. fresh ears. Champagne-fueled night vs. coffee morning sessions reveal nuances in soundstage and immersion. Not for quick-scrollers—stay for the depth. Part 2 at 50 hours. What bias should I test next?
