I'm sorry I was not clear. I can't explain it, the TA-ZH1ES is so so good. ZR1 was awesome with it but the Utopias was like wow. I was really surprised because I didn't expect that from Sony. I think for my ears, the Utopia can be a little bright and the TA-ZH1ES to me is a bit warmer as a sound signature so it tames the Utopia but I the clarity and the resolution is there. I actually want to do an A/B comparison with the Sony amp and whatever AMP I pair my Schiit Yggdrasil with. I was blown away at how much I really liked that combination. So much so that I went and purchased the Utopia new and bought the ZR1 used. I'm now hunting for the TA-ZH1ES on the used market. If I don't find one in the next month or so, I might have to give in and buy new.
In the meantime, I'm typing this post while listening to the Utopia on a Lyr2/Bifrost multibit stack. Sounds really good and If I have to live with this stack, I will be happy. However, I want to chase what I heard while I was at Source AV and recreate it. Mind you, this was over 3 separate visits and each time, I was astounded by the combination.
