I am building a cmoy, but, I want it to be the best cmoy you can make for under 150, and I also need to make a ety er4P->S cable, any suggestions on parts for each. A zune is my source, and I listen to metal of all kinds, and punk rock. I have basic soldering skills, and have had an electronics class before.
Thank you ahead of time

If you've got such a large budget for a cmoy, you may want to consider building a somewhat better amp. In fact, I'm not really sure if you can make a CMOy that expensive, unless you go overboard with audio voodoo on the casing / jacks / resistors / capacitors / wiring / etc

I don't know what size you want the amp to be, but assuming an altoids-sized amp, given your basic soldering skills and the fact that you're using a pair of etys, you might want to try out an a47, which is designed for low impedance loads like IEMs. an er4p=>s cable kinda negates the benefit of this particular design, though.
Some other good amps in this price range (or at least better than the CMOY):
PPAS, but it's surface mount and probalby not suitable
PIEMTA, but so far it's only been designed on a pretty large board which isn't really portable IMO
PINT, but it's discontinued and surface mount

oh right, i almost forgot, there's a mini^3 amp being developed right now. I think boards for the amp will come out next month or so. I'd say that's your best choice. It's probably still going to come out under $150.

what would you recommend my good friend?

Wait a teensy bit until the Mini^3 (http://www.amb.org/audio/mini3/) boards go on sale. Spending that much on a CMOY is ______.

Thank you, sounds interesting. Any help with the p to s cable?

just put two 75 ohm resistors inline, on L and R wire. you could even build it into the amp itself - that would save you the hassle of carrying the cable and the amp around. this would be no prob with a cmoy or a pimeta, dunno if you can fit it into a mini^3. just looked it up - it should work with some free-air wiring.

you could also build a B^3 amp when it comes out - maybe I'll post it tomorrow. ok, forget the last sentence, this was shameless self advertisement

hmm, seems easy enough, hmm, how much would you say it would cost to make a nice pimeta?

 

[balou]

that depends on parts - but if you don't make the same opamp buying spree like me, you will be below your 150$ limit.

 

[ZackP]

hmm, what would be a good op amp for metal music with good seperation of instruments? And what would be the best parts for it?

good separation - anything with a ground channel. I'd say pimeta or mini^3

Pimeta should come in well under $150.
