I just got delivery of a pair of Shuguang WE845 from China (eBay Purchase). It took a month for the delivery. I replaced the original tubes from Cary CAD-805, which had been used for ~6yrs. Before their arrival, I used GE 211 tubes for a while. Anyway, I run the amps with WE845 only for 10hr or so, but they sound amazing already. Soundstage becomes incredibly deep and wide, and the texture of music is much dense and real. With good recordings that I am very familiar with, I feels like they are here to play the music just for me rather I was there. I do not have any experience with Psvane WE845 so I can not compare them. But I am very impressed with SG WE845 in their sound reproduction and build quality.
I will leave my feedback after ~100hr.
