I wouldn't get too stuck on square wave response, despite the popularity in the "free press". My amp has zero feedback, so the front-end response is just that - and it shows a tremendous rise fall time.
The front-end by itself extends to well over 500 KHz, while the whole amp from input to 8 ohm output (I measured at 10 watts) extends to 80 KHz - without any global feedback.
The front-end produces a near-perfect 10 KHz square wave. The amp as a whole shows some smoothing of rise and fall, as one might expect. But do you really care when it extends beyond the last RIAA mandated pole (that very few implement anyway...), not to mention the roloff of your super tweeters at 40 KHz (typical) and your average ear at 13 KHz (as I found in a group test!)...
