Right now, I am using the Radio Shack 1.0uF (x 2) metal film caps for the input caps, but I will also try a pair of Black Gate N 4.7uF bypassed with 1.0uF, and a pair of Epcos MKV B25834 3.3uF film/oil bypassed with some Russian Teflon caps.
I just changed input caps to 4.7uf and can testify that it made an improvement for me. However I dont think that you need just as high if you keep the 20k input resistors supplied on that amp.

I made an online calculator that works out the gain and cutoff frequency for the Tripath amps, you can input your cap values to see how that affects the frequency of the high pass frequency.

TA2024 Gain and High pass Filter calculator

I have mislabeled the HPF LPF on the calculator which I will correct when I get a minute.
