X200 vs A50i both are very nice and I own the X200 and did demo the a20i and for my needs the X200 was the choice.
V70 is very nice and a friend has one and she said it took a long while for it to well sound right. Those are her words. She said the first few weeks she was ready to send it back that's how bad it sounded.
With the X200 you do have a lot of tube choices and many people are all "you have to run the KT170" well I did and they are okay but I prefer the all around great sound of the KT120 and when wanting to listen to classical critically I pop KT88's in. I listen to all formats, Streaming Q, CD and Analog or LP.
I have QLN Prestige Three's at 88 ish dB the X200 sounds fantastic with them.
