Hey Ron, have you found that the LMH6643 works best for you in the DAC socket? Seems like it is after reading your earlier posts again.

Changing the LCD brightness will also affect the pitch of this noise. Its pretty low in volume so if i put on a music then chances are i cant hear it since it drowned out with the music unless when i'm hearing like a podcast or something which doesnt have instruments on its background. |

Have you tried one of the USB-mini connector with one of those cylindrical chokes (or whatever they are called) at the end to see if that would clean up the signal? I'll take a picture of one if you don't know what I mean. |

The AD8397's buffer is punchier, and the AD8099 in LR. If you can't find the punch in the D1 in that config, you won't find punch in any amps IMO. I used to have a PPA which is a punchy amp, and the D1 delivers that bass punch with the above mentioned combo. |

Based on the MOVE thread this problem can be fixed by getting an external powered hub but to me that would just kill the portability even more. I'll just see if i can try an ibasso this weekend and check it myself if the problem is still there it doesnt really bother me since the volume is pretty low and its not really evident on a full size headphone but you can hear it clearly on an low impedance/sensitive earphones. |
