If you're not follow my blog yet, perhaps you might wonder what amplifier that I am talking about. So please read on here here and here . This is Tripath TA2024 amplifier from Topping. I did upgrade the components and add the DAC from TDA1543 into one casing. The goal when making this amp is make the sound just like a F5 amplifier. It is sound good by the way, but not close to the F5 yet. So, recently after I do testing the H2, I am fully confident that adding it will improve the sound.
