Nuprime st10 or nuforce sta200, or parasound a23


Hi, in thinking to upgrade my amp  a parasound zamp v3, it's powering a pair of paradigm signature s1v3, looking to improve depth, imaging and mid frequencies .
Despite of price differences, which one would you recommend?
Thanks four your advice

Mytek just announced a new 2x300W amp - small and they claim it has Class A triode quality sound.

So I'd want to add that to your listen list.
The st10 is really good and the new Mytek might be good also.
I can't really recommend a parasound,bright and lean in the mids.
