I have the 834p and the Dynavector 20x2 L (low output). Ended up selling a $4k solid state phono pre during covid time and never looked back.
I did enough research to understand that for best results I needed an external SUT and keep the 834p in MM mode all the time.
I bought the Ned Clayton Moving Coil Phono Step Up Transformer with Cinemag 1254 4 Ratios 1:10 - 1:40 MC SUT on ebay. Works great. The Cinemag transformers well reviewed and this SUT was about 1/3 of the price of (I forgot the name) the other one I was looking at.
