I recently built a CMoy amp from the design on tangent's site and added my own flair to it in a couple of ways. I appreciated the simplicity of it and the elegance within this simplicity.....but I could see its flaws....although I don't have a quality amp in it yet (have a BB opa2132 on order and the current one in it is a TL082C from radio shack DX) I know that that isnt the only issue with its quality. It doesnt sound "bad" per se it just doesn't sound "life changing". So I now want to complete a heftier amp that can reproduce at a much higher quality. I have a list of things I would LIKE to have in it and I have some ideas for ones I want to build (all of them also from tangent's site)
What I want:
bass boost: For real high power, punch you in the face, implode your eardrums with awesome sauce bass hits. (My headphones of choice are...well....different. Unlike the other audiophiles on this forum I went a different route for finding headphones. I decided to buy a gimmick just for the hell of it and see if anything came of it. If you want to see what I bought click here. I think I found a diamond in the rough (although the company has quality issues) because these are the bassiest headphones I've ever owned (bass is very important to me because I am a dubstep fan and I do a bit of producing from time to time) I am happy with them am not in the mood to be chided for buying a gimmick. I understand that its a gimmick, but they actually do punch out hard bass.)
load forberance: I want an amp that has the ability to still reproduce highs when the bass is super heavy. I have an issue with my device and type of music that the highs some times get drowned out when the bass is heavy and then they POP Out when the bass goes down for a moment creating a terrible effect.
Form factor that can fit within a backpack/laptop bag: I will use this for listening while at school and walking around so I'd like to have it in my backpack and just plug my stuff up to it in there.
battery life: the pack that comes with it should last at least half a day (I could possibly build 2 packs and switch out in the day)
general quality: I want it to be incredibly crystal clear. When I got my new headphones I heard things in my music that I had never heard before because of their ability to reproduce heavy and high frequencies well. It had more depth and the soundstage was incredible. If I could get a similar upgrade from an amp that would be wonderful.
bells and whistles: I like features that I can configure and turn on and off to adjust for what I'm doing at the present moment. I can say that when I got my first Android device and got PowerAmp I was amazed. I could control the full equalizer on a device that could actually reproduce volume. (my desktop has ok volume and the lappy has crap for volume and although both have EQs they aren't very advanced (even though the desktop has dolby digital 7.1 built in) The point of me saying this is that when I was able to tweak I was happy.
Ideas I have for amps that might fit the Bill:
PPA v2 -- seems like best choice but also most expensive
PIMETA v2 -- seems like second best but I really wanted to up it to the PPA v2 from this to get the extra features and quality
META42 -- heard about this somewhere and seemed like it might fit
ANY HELP OR ADVICE IS WELCOME!
thank you in advance
