First and foremost what speakers, room dimension, and music listened to. I've heard the Hegel...it really is great. I've not heard the Musical Fidelity but I've heard both of the smaller units. It is a best buy for power and good sound. I have not heard anything from Krell I would own as too antiseptic. It is clean, quiet and has balls, but is the least musical of the 3. Just my opinion. Hope it helps. Good luck.
