You said in Tokyo soon. Would you be talking about the Portable Audio Festival 2012 on the 20th and 21st. Either way i'm planning on going.

i purchased V-MODA VAMP today and use it with my ipod nano 6th generation. my earphone is final audio design FI-BA-SS.

The sound from phone out of VAMP is an upgrade when compared to the phone out of ipod nano.

However, i heard the background noise sound when switching on amplifier when playing the music. This condition (background noise sound) continue even i press "pause" to the ipod nano.

Is this the normal situation when switching on the V-MODA VAMP for music listening? As i don't like such  relatively hight level of background noise sound. Would Someone give suggestions or opinion to minimize/relieve this issue???

Because FI-BA-SS is a rather sensitive earphone.

Im using Heaven IV earphone from FAD with VAMP and I can heard the noise too.

It should be normal.

If you wanna solve it

Just use a resistor plug  to increase the resistance in order to reduce (filter) the bg noise.

But using a resistor plug will increase the output impedance and lower the damping factor, causing audible distortions if your headphone has low impedance and a "curvy" impedance-frequency curve. Your call.

Thank You.. So I decided not to use FI-BA-SS now. Instead, i 'm using Pioneeer HDJ-2000 with silver cable. The result is amazing and canexplore the sound quality potential of V-moda Vamp. Very very little background noise and overall music-listening quality (sound stage, treble/bass/neural components) is improving a lot, especially listening some western and japan songs (Boyz II Men, Eagles, Chemistry and Ken kirai etc).

but another issue arising is that ipod nano 6 only have battery life for 3.5hrs when pairing up with V-moda Vamp , which is much faster when using ipod nano 6 without amplifer. Is this the normal condition??

Thank you for your kind assistane in providing suggestion for me.

Now i changed to use pioneer hdj2000 with sliver cable.

Another issue is that: is new ipod nano 7 compatible with V-moda Vamp if i purchased "lightning to 30-pin adapter" as interconnection between ipod nano 7 and v-moda vamp??? Anyone have such information about this issue???

Hi Kelvin,

There should not be any noise as the Signal to Noise ratio is rather high and VAMP is using the lowest noise op.amp. component.

Are you using an extension cable with ipod nano?

The noise will probably from below sources:

1) The interferance of phone signal transmission, if using iPhone 4/4S (solution: to switch to airplane mode)

2) The firmware not compatible (solution: to switch off your ipod/ ipad / iphone when it is installed inside VAMP, then turn it on again, it will match pair again)

3) The firmware not match with iOS 6 in iPhone 4/4S.  You have to call the customer service for upgrade the firmware of VAMP.

Let me know if you need further help.

Thanks for your information!

I haven't owned any iphone4/4S product so that i have no such problems related to point 1 and point 3.

In using fi-ba-ss earphone, i had repeated the steps that mentioned to point 2, but problems still arised. This problem is not related to the V-moda Vamp itself.

I think that the problem for the background noise is the earphone (fi-ba-ss) in which is relatively senisitive to vamp. As i used pioneer hdj-2000 headphone in listening music with ipod nano 5/ipod nano 6 + v-moda vamp now, no such background noise problem arising now....

For me, V-moda Vamp give a new life for my ipod nano 5 and ipod nano 6. These two players can easily plugged into Vamp without any interconnect cables, that is very convenience for me. The size and weight of these combination (ipod nano 5 or ipod nano 6 + v-moda vamp) is acceptable me. (less than 200g) when comparing with my previous portable gear set up. High quality sound can be produced with these small and portable combination, it is amazing and enjoyable in which i purchased v-moda vamp because of my curiousity about the news of vamp!!!!

(PS: i used ipod nano 6 + iqube v1 + qables Silvercab-Hybrid cable previously, that is also portable to me, but now ipod nano + V-moda vamp become my portable music listening gear!!)

Greetings, Anouk,

the next VAMP will, its based on Go-Dap X

Hi,

YES, the new vamp will support more platforms, please stay tuned.  I think Val will release more information very soon!

Ok silly question: how much background noise is normal for the VAMP in low gain?  This has been bugging me for a while ever since I got my VAMP, and I tested it with all of my IEMs and found that my UE900 has the lease amount of hiss.

well with AKG K242HD (which is not efficient) none. completely black. on high gain
