(Sorry if this has been asked before; But, forty pages of partially relevant discussion using the search feature... Only make my question, too difficult to answer via myself.) Any way, I am new to portable amps; Can somebody recommend "The best," match for the Grado Rs-1? My only...

Do all headphone amps support 24 bit @ 192Khz, as PCM stream? Like, if my Playstation 3 outputs this through the stereo, analog, outputs w/ a Blu-Ray movie... will my headphone amplifier work fine? Any help is appreciated, thank you.

Simply, How do tube amplifiers react to analog outputs of: Television, DVR, Etc...? I decided on the Mapletree as my first headphone amplifier, but have not read a single comment on it's performance w/ my repeated comments... Is it even possible? I read I could use the RA-1 just fine...
