An amazing little... nay, tiny headphone amp that can sound nearly as good as my Portable META...

 

you really should give his amps a listen...

 

Very interesting, I would love to try it I must say that I should learn more about it, how to make good sound in small size

 

HOws the amp selling in this site?? Which Cap and op-Amp use is better?? which one is better suit for my Grado SR80.. if i want to tame down the high and increase the bass level??

 

You can check Tangent's site, about the Notes for Audio Op-Amp, or my small review of various Op-Amp I tested:

You better check DIY forum to get more info.

 

About local DIY amp, I see we have a few approaches:

1. A complete amp for those who don't do DIY.

2. Just a PCB for those who can do DIY, or want to start to do DIY (carefull it is addictive ).

3. Only guidance, for those who want to make it 100% by himself.

 

And about the amp itself, there are three major common design:

1. CMoy, mostly depend on the Op-Amp capability. Good or bad depend on the Op-Amp you choose for specific headphone. Normally cost around SGD 25 - 50 depend on the component selection (can be less can be more).

2. A47, Jason has started budget amp with this configuration. Check:

3. Jung's multiloop, like Pimeta and PPA. I cannot call it budget amp, as the buffers are costly, anyway it is depend on the how much is max cost for budget amp.

 

Probably we can start interest check for it

 

As I see most of the DIYers are busy people, so please, no rush

I'm probably getting one from Norm before I return to Singapore at the end of Oct.

 

Oh, by the way...does anyone know if I can get Plainviews in Singapore? Or perhaps any other good found-in-Singapore brands....

AFAIK, you can't get plainviews in Singapore so it might be good to order them from Norm. GP batteries are the most common locally, but they aren't 9V. I remember mention of alternatives available locally on this forum, you might want to do a search.

Actually if i'm not wrong there are GP rechargables that are 9V.. Saw them at SLT.

[N@Z 0]

Stryder, if you look closely, they are actually rated at 8.4V. The plainviews are 9.6V.

[lekguan 0]

They are 9V replacement, and do work, except that plainviews tend to provide more weight to the cans due to the extra 1.2V.

Guess I'll just grab a plainview from Norm then....thanks guys.
