Hi!

 

As the title says, are there any amps that resists GSM interference?

I use my iPhone as my main portable souce, and I'm pretty annoyed by the GSM interference when using an amp.

I use a Leckerton Audio UHA-4 and have no interference.
 
I had a lot of annoying interferences with my S:flo2's HeadphoneOut and noticed that the LineOut was clean, so when I choosed an amp it was crucial it didn't add other interferences.

Really? I never read that about them. I might get a Pico slim, but it's a little out of my budget.. But maybe.. Anyway, thanks :)

Uhh, Leverton UHA-4. I am seriously thinking about that one. It's a very interesting product.
Have you had an experience the amp while using an iPhone/phone as source?

 

 

Any other GSM protected amps?

The E11 was designed to be resistant to GSM interference.  Not sure exactly how much though.

I have no iPhone.

 

The S:flo2 headphone out was affected by my BlackBerry GSM interferences, while its line out was not.

The only sure fact I can contribute is that the UHA-4 is resistant to my BlackBerry interferences.

 

I also have an iPod classic, but that one never suffered from GSM interferences, so little point in testing it with UHA-4

Though the Pico Slim is a lot better than the other amps I've owned (D10, D12, TTVJ Slim, cMoyBB etc), it is definitely not 100% interference resistant. In fact It's annoying enough I don't use the Slim with my iPhone 4. Maybe it's just me redface.gif

I guess these should help if you don't mind using a pouch with your amp.

Oh man, that sucks :P

I won't be getting the Slim then.

 

The iPhone 4 really is prone to cause interference with amps, and it's really annoying.

Thanks for the link, but it's not really the solution I am looking for. This solution prevents me from using my Phone/WiFI/stuff and that can be achieved simply by putting my iPhone in Airplane-mode, which how I usually beat the interference, but then I cannot use many of my phones functions, which is really annoying.

What if you put only the amp in the pouch? That wouldnt block any calls etc. since your iPhone is outside.

My iPhone 4 never interferes with my Graham Slee Voyager amp, however, if I put my BlackBerry Bold 2 next to it, I do get interference.

The is strange.. Maybe it also depends on where in the world you are, as there are many different GSM signals.
