Depends. Overall, BHK 250. There’s a sweetness and musicality to the BHK amps that simply cannot be touched (or has yet to be touched).
What’s difficult is what this implies. It implies the M1200s are lacking when, in fact, no one listening to them would have that feeling cross their minds. When you’re listening to the M1200s you’ve got a giant smile on your face like being on
a fun ride. Never do you yearn for this or miss that. It isn’t until you roll your sleeves up and do the hard work of AB comparisons between the two where you say to yourself, ahh, yes. The BHK 250/300s still have the edge.
That’s a far cry from a blank statement of which is better or worse.
