The Lyngdorf 2170 may not be "forever" for me, but it's certainly gotten me to an expansive plateau in my system upgrades. I'm sure the new 3400 is equally as good. I did quite a bit of side by side testing when I purchased the 2170 against some pretty stiff and expensive competition. I was very surprised this class D-ish amp bested all comers SS and Tube. Both utilizing analog inputs and digital using it's internal DAC for digital. It's a gold plated Swiss army knife of an amp in my opinion.
