First, let me just say I was unsure which part of the forums to post this in, but this part seemed a safe bet. So let me describe my conundrum:
I have a Kenwood KR-V7070 receiver and I'm using the headphone out with a few of my headphones. I tried it with my T50rp IIs, MDR-MA900s, ATH-M35s, HA-RX900and even some low-end in ears (V-Moda Bassfreq Metal).
Out of all these various headphones, only the RX900 suffers from a low volume static/hiss noise at even the lowest volume setting on the receiver (if it matters, the noise is equal volume at all volume settings) and additionally, the RX900 doesn't suffer from any sort of noise when using it with my Schiit Magni at normal and even moderately high volumes, nor with my Sansa Clip+ and computer.
Is there anyone who knows what might be up here? I'm unsure of the receiver specs, but I'll post all the headphone info I think might be useful below:
Audio Technica ATH-M35: 65 ohms 100 db/mw
Fostex T50rp II: 50 ohms 98 db/mw
JVC HA-RX900: 64 ohms 105 db/mw
Sony MDR-MA900: 12 ohms 104 db/mw
Thanks for anyone who can help me understand this my problem! c:
