Simaudio P5 or Conrad Johnson ET5

I currently have the CJ 17LS and like it a lot but I do feel like it may be the bottle neck in my system.  Therefore I am looking to replace with something that can provide better detail and dynamic.  The ET5 seems like a natural candidate but its weakness is that it does not offer balance connection which in itself could be the bottleneck.  The P5 is a two chassis design and has the sound somewhere between tube and solid state.  
The P5 used would be around 2K and the ET5 would probably around 4K or a bit less if I am lucky.
My current amp is Simaudio Moon W3.  The DAC is Ayre QB-9 DSD.

What are some of the alternatives with about the same price?
