Default phase issues when using a .01uf in parallel with the input capacitors?

I tried to use a .01uf/100VDC polystyrene capacitor at the input as bypass capacitor for the 2.2uf cap and i found a decent hf clarity but it seemed like some phase issue and sounded muffled in the midrange. Does it has any effect on the phase?

so is it good to have small cap as low as .01uf and 18pf bypass at the input?

Did you use a higher quality bypass cap? IME, often the sound character shifts to whatever the bypass is.

Those additional caps will make absolutely no difference.

The major factor is dissipation factor, but most inputs will have a series resistance that swamps it out completely. Shouldn't matter. It shouldn't be audible unless the other cap has astoundingly bad response or something. Input of what?

I think this is happening because of the inductance of the 2.2uf cap as there would be inductive winding and once we use a small cap it might be passing the hf info more from the smaller cap and hence making it a bit difference in hf..
