Hi, I'm an electronics technician student. I'm interested in starting my first independant project. All others have been related to school. Just a couple of questions that I need some clarification on.
I've just ordered a pair of Sennheiser 580s. I sold my mid-grade amp to get them, so I'd like to build an amp.
I'm interested in building the Meier crossfeed amp with a buffer output.

After speaking to a collegue with expereince in audio he recommended the OPA134/2134 for the front end and the BUF634 (TO-220) for the driver, both by Burr-Brown. I've been checking up on metal film resistors and polypropylene caps.
1. Is it better to have a small compact ciruit when it comes the headphone amps or can I spread it ot over the board without worrying about interference?
2. I plan to use an amp in the home and not for portability. Which brings me to the next question.
Would the sound quality of a larger circuit better that of a pocket amplifier or are they comparable?
3. I like listening to my records. The output on my record player is very low compared to my CD player:
Should I create a circuit with a separate phono input or will the intended circuit perform well?
Would a screw for chasis ground do the job of chasis grounding or is there someting more I need to do?
4. Does anyone know of a high frequency filter that would reduce the pops an cracks from the records?
An help would be greatly appreciated.
