Vcoheda, do those isolation and vibration control devices have any actual impact in your headphone listening? I'm thinking that the lack of airbourne vibrations would reduce the impact to close to nil.
I've got HRS isolation for my CDP and TT, but I thought it would only be effective when using my speakers.
Let us know when you get the HeAudio EH-1.3. I'm very curious about that. I see almost no discussion of it at Head-Fi, yet it looks very promising. I'd love to see a comparison to your other cans.
My headphone setup is relatively modest, with a Woo Audio WA6 driving AKG K701s, UE Triple.fi 10 Pros and UE Super.fi 5 Pros. I use the UEs mainly when traveling, but occasionally they come out at home when I need more isolation than the AKGs afford. Jack Wu makes great HP amps.
