Sometime ago I read in this forum about the sound quality, convenience and low footprint of the topping class D amplifiers. As I have recently sold off my stereo setup to upgrade and yet to seriously start auditioning amplifiers I thought why not get a topping amp as a stop gap measure and a 2nd amp to carry around to friend's places etc...while going through different models it was daunting and confusing given various chips used, their pros and cons and the confusing power output ratings...So I decided to compile everything in an excel file so that I can compare and take a decision, so posting the compilation here, hope it helps other fms looking at Topping amps too...
