You'll be surprised how low an in put you need if you use it this way although Gary says it is best to adjust mp3 to 50-60% and use the volume control on the PA2, even to attenuate the signal. |

Also, having the charger plugged in while playing adds even more noise. Is the noise issue really fixed with the V2? |

I haven't really listened with the ac adaptor, but that that issue seems to have been addressed in this thread. |

I recently started investing in better headphones for my ipod/computer, and now have a great trifecta: grado sr-80s, etymotic er-6i's, and sony ex81s. The er-6i's have awesome noise isolation (esp. with foam), but they lack bass and soundstage, so particularly for them, i went on the market for a good but cheap amp. I went with a Cmoy on ebay, from a very highly regarded seller, but I was disappointed to find that it had a lot of hiss, especially on the etys. He thought that it was defective, so he sent me a new one, with a set gain of 4.3 (instead of the 11 of the first, which made the etys almost too loud on the lowest ipod setting). I got that yesterday, and it still has background hiss - I can hear it most with my etys (16 ohms), and less with the grados and sonys. Plus, it matters which source I'm using - a lot with my powerbook, less but still noticeable with my 4G ipod, and the least with my 2G ipod (still ticking!). But the hiss is getting to me, since I want to use it with my 4G ipod. I went out and got gold 1/8" to 1/8" plugs, which seemed to help some but not too much. SO - I was thinking about trying out a different amp, like this pocket amp 2, and wanted to get your guys' read on this. I am no audiophile or expert with all the terminology, but I am starting to get pretty discriminating, and definitely don't like the hiss (what's the point of in-ear phones like the etys?). Do you think that a low impedance will always give me hiss in the etys? Would a gain knob on an amp, as with the pocket amp 2 help? Would a pocket amp 2 not boost the bass and soundstage enough? (since it seems like the op chip isn't as good?). Lastly, could burning in the Cmoy help with the hiss, or just the sound quality? Thanks in advance for your comments! |
