I'd tend to be suspicious of a comparatively complex design at that pricepoint, but your ears are the test (though not of trouble free use over time, of course).
If the Sinclairs image with the Gallo 3.5s that is very high praise, in my book, since I think the 3.5s have spooky-good imaging and sound staging (I suspect the height issue is tweakable). I think the 3.5s an outstanding value at their pricepoint; if the Sinclairs are competitive at a third of a good street price on the 3.5s, they are a stunningly good deal, IME.
Put that way, sounds a little too good to be true, eh?
