I agree with Tvad.
It seems rare, at least to me, to see a manufacturer upgrade a product as quickly as the folks at NuForce have done with their little amplifier. I believe all models are still available to accommodate price and/or usage constraints of the customer. It seems the SE was by far the biggest upgrade. If I were them I'd be working on a balanced multichannel preamp or Home Theater processor, to include bypass, mute, monaural, and phase switches.
