Ok, I to have a 51SE and P10SE. I'm running a single 75SE amp with my Watt/Puppy 6 speakers.
I have not heard the new VK600 or SE model. I have owned both the VK200 and VK60, which are earlier models of BAT's Solid State and Tube amps.
Differences boil down to SS vs Tube. The SS had better bass control, the Tube much airier top end, better soundstaging, better mids. The 75SE is no slouch in the bass, it's significantly improved over the old VK60.
Isn't your Genensis 501's powered on the bass? If so, stick with tubes.
I will say, the Atmoshperes are good amps. If you like them, you might want to stick with them. Get the Super Pak update on your phono stage...it's supposed to be big.
Save the money on the amps...
