I also have the S-250. I listened to three different types of speakers (planar, conventional, and single driver), one at a time of course depending on my preference, powered by this amp and all I can say is that "I have found it"!
As the posters above mentioned, Mr. Henry Ho is a no non-sense low key guy. He seldom participate in discussion forums and does not advertised his product. Like Pkaram, I bought mine without hearing it and just took my chances. Almost three months now since I received the amp and so far, I have no complaints on how the amp sound in my set up.
FWIW, the amp has a trial period and a demo unit can be requested (for a week stay in your system) from Mr. Ho. Maybe the best thing is to hear it first in your rig so you can make your decision.
