I've been using Neo 6 a lot lately with my SP2. I find that I'm hearing more instrument & channel seperation & detail particularly in the higher frequency range. This is with basic stereo cd which is dts matrixed into 6 channels. Getting the center channel calibrated right is key to getting it to sound right.
Dolby Pro Logic II sounds good but I rarely use it for music. Because in my opinion it flattens out linears highs, which is the attribute of the SST2 amp, which I like. So why would I want to flatten it out?
Anyway if you're using a multi-channel processor give Neo 6 a try.
