Sionlim,
I looked at some of your other posts, and I want to add something that is absolutely critical.. it's SYNERGY.. The Spirit III is an amazing amp, yes a very big slice of Uber-ness for non Uber-ness money.. This can all be erased with a LACK of synergy.. Getting the most from the amp means pairing with the right speakers, with the right cables, with good power line products, with the right front end, proper setup, etc, keep this in mind.. I think you understand this from the experience you've have had with the other gear in your home that should sound good but doesn't..
And other speakers that work well with the Ayon would be Harbeth 7-ES3, Again Proac D2, or better, D40 would be fantastic but pricey, stay away from Maggies not enough power, Merlins, Dynaudio, Focal, Devore, all would be good matches IF you like the way they sound.. Stick with reasonably efficient, and reasonably simple loads.. no weird 3 ohm speakers.. And Triode mode sounds amazing, but won't with the wrong speaker..
