R’ Viener’s website torahstream.org.
Kesubos, Navi B’Iyun, Hilchos Shabbos, Sanhedrin, and much more.
I like listening to R’Viener because he makes everything come alive in the shiur- the understanding is so sharp and clear. I feel like everything is given over with tremendous Daas Torah and humor and practicality, and I truly experience the sweetness of learning.
Hope it helps! Kol Tuv.
