What about Shadow and RX amps ?

Hey Rob, I would like to hear about Meier Arietta (Now Swing) against your top most portable Lisa. If mobility isn't an issue, which one would you prefer. Cheers...

thanks...but what i should've said would it at least drive them to about 75% of their full potential?

especially the ibasso d4

i am also interested in d4, do you view the d4 as a high cost / price ratio product?

thanks skylab

BlackStarPUA and Dazed&Confused718 you (as well as all others) should fill in your data so others know where you are located. I say this because you could have a fellow Head-Fier living close to you who might be able to meet with you at library or a café and let you test the piece of gear you are interested in. However you have chosen not to divulge that information and ...

thanks Skylab~ You are sooo~ nice!

DO I NEED AMP ?

HI NEED SOME INFO I HAVE A PAIR OF KOSS PORTAPRO AND SANSA Clip Plus + 8 GB THESE ARE CHRISTMAS GIFTS I HAVE NOT OPENED YET. DO I NEED AMP TO POWER KOSS PORTAPRO?

No, you just need to turn of Caps Lock.

I agree mate.

+1, but sadly this isnt the only caps-lock equipped warrior on Head-Fi.

There's the notion that because we wear headphones a lot we have some kind of hearing loss hence the SHOUTING.

Ummm...you do need to turn off the Caps Lock key, as others have pointed out. But I can answer your question. I am a long-time PortaPro user, and until I stupidly lost my Clip+ a couple of weeks ago, I was using the exact combination you are asking about.

In short: no, you don't need an amp for this combination. The PortaPros are quite efficient and sound very good plugged into just about any quality portable, such as the Clip. That said, the Clip's internal amp is not the most powerful I've heard, so if you choose to fry your ears at very high volume, you may want to add an amp.

I do not recommend this. At the very least, try the PortaPro/Clip combo first, to see how you like it. I suspect you will be very satisfied and will not want to add an amp. An amp is also inadvisable with this combination because the PPs offer very little isolation. In noisy situations, you may be tempted to crank an amp to levels that sound great while you are listening, despite the fact that you are harming your ears.

So, in sum, you do not need to amp your Clip to use it with PortaPros. This is a great combination; I think you're gonna love it! Don't forget to thank the thoughtful person who got you this great present!
