Interesting topic.
In our hifi world,there are 2 fields,and let me confused in the past,but now I realised they are the 2 fields. One is the SS Amplifier and one is tube amplifier. The sound is just can't not compare. Some one might object the idea,as they will point out some good SS amplifier,the sound is better than some tube amplifier. Yes,that's right. but I am talking about good to good,normal to normal,and bad to bad.
In SS world,pass XA30.8 is the one of top amplifier,and if there is door inbetween these 2 worlds ,XA30.8 is located very near the door.
Some people actually realised the same idea (sure,be different language),and step into the tube world after long listening,and never back.
Some people ask to be easy listenning,and they step back to SS amplifier. It is
happening everyday.
