Actually I'm guilty of sub 100 hz bass boost, since we can't feel the bass as with speakers or live performance, I'll take this crutch.
The Lepai isn't my cup of tea, too much distortion. I bought an LP-2020A+ to see what it was, since it was priced like a large pizza pie with sausage and extra cheese, I didn't have much to lose. They rate the distortion low, but once you turn up the volume it goes downhill fast. So I gave it away. So in the spirit of giving, give me your HD800's.
If I didn't have much to spend on an amp, I'd save a little more and get a Schiit Magni or if I was dead set on speaker taps, I'd get an inexpensive $100 stereo receiver with FM radio and tone controls. Some of the established brands make 2 channel stereo receivers at that price point that put out around 100W. That's enough to singe one's ears and fry their phones.
