Sorry to revive this thread, but is this amp still relevant???

 

[jamato8]

That is up to you and your ears. I guess it is relevant enough to revive the thread. :^)

Thank you for everyone for sharing your experience.
It was this forum that mainly led me to buy one rsa predator.
Sorry for the off,
But I got a probem I wonder maybe someone can help me.
I bought the rsa predator second hand, that time I didn't have a hifi headphone so I tried with a skullcandy aviator it seemd okay together.
A few days later I bought a sennheiser hd650.
When I try to use on hi gain with line out and I turn a volume up it's just around 65% there is a creaking sound.
Especially the deep section suffers.
I tooke the amp apart and as I saw the on battery; replacement for ipod 3rd generation.
Is that his battery?
Thanks in advance.

The Predator was designed for low impedance headphones & IEMs. When pairing it with HD600, 300 ohms, high impedance headphones, the battery voltage, 3.7, is not sufficient enough to play at "high gain" the headphones that was not designed for that's why you get that clipping noise. If you want the amp that can do HD600 well, the the Intruder is the answer.

A great portable headphone and one that works well with the Predator are the Koss PortaPros. There are simple modifications to the portapros that open up the sound from them more. To me, they are an exceptional bargain and a great portable phone for little money. They are better than many phones costing much more and hold up better and. . . they come with a lifetime warranty that Koss stands behind.

Thank you very much. I'll check that.

Hello Ray, If you are there, I was wondering what you think about the JH13Pro and Predator pairing?

 

[ksk75]

Hi,

Interested as well,

Thanks

Hi

I just jumped for a sennheiser IE80 that was a clearance at the shop.
With the RSA just so sweet....
Actually I like better than my HD 650 (ok I don't have a proper dac yet) and the portability is a huge + for me.
So just thanks for those guys who's wrote about that amp/dac. They lead me to buy

Why is thread dead?  Is there another predator thread?  I really like mine.

 

[jamato8]

Just this one. Don't know why there isn't more input. The one constant is change.

Zombie alert... I recently purchased a Predator, tried to hook it up to my iPod 6 with a CCK and got the dreaded, "The connected USB device requires too much power" message.
 
Please tell me there is a solution other than added a powered hub to the already unwieldy cables.
