I have a Lepai TA2020A+ as well. Got it hooked up to my pair of Wharfedale Diamond 10.2's and they freaking sing compared to what I previously had.
Toslink to Pioneer VSX-519 and Wharfe's hooked to the Pioneer.
Now I have the Lepai hooked straight to my Gene-Z analog audio out and they sound much much better. It powers them really good.
My setup is going to sound even better when I get a Audinst HUD-MX1 to act as a DAC and get the 10meter long Techlink Wires1st RCA interconnects I ordered from Jimm's. I'll have the signal going from the DAC first to the subwoofer and let it handle crossover and then to my Lepai.
I'm gonna do some modding to the Lepai as soon as I have time, I already ordered another one of those Lepai's so I have a backup if I manage to fry the damn thing LOL.
So another set of speakers to add to the list But to be honest, this Lepai can power pretty much anything, check YT video named 'Little Amp, Big Speakers'
Glad to hear your happy experience with the Lepai TA2020 and yes list page 1, post #4 long due for an update
Usually i take videos of audio hardware playing with a pinch of salt due to quality of the audio side of recording but a rough idea of how the TA2020 does for classical music
it was only after moving away from awful, muddy sounding PC/Multimedia setups that i decided to explore genres of music i didn't think i'd like before and i thoroughly enjoyed Tchaikovsky's Dance of the Sugar Plum fairy on my humble Polk M3/TA2020/E7
