Too bad iBasso doesn't have any reseller in the UK that I can come try the P5 :(

Just pulled the trigger and can't wait for mine to arrive :D

Thank you a lot for the response. My Sony NWZ A17's having a hard time driving the HD700, but they do sound great together, so I'm thinking whether to get the HA-2 or spend the money for an amp only. Decision...

Not sure if this is asked already, but can anyone tell me if the HA-2 is powerful enough to drive the Sennheiser HD700? Thanks.

Do you know what happened to the P5? It doesn't show up on iBasso site http://ibasso.com/product.php

Username: Doralikesmath I would love to have some high-end headphones like the Sennheiser HD800 or the LCD on Massdrop.

If you need a good DAC, go for the Cruise. Regarding the amp, it depends on personal preference. It would be helpful if you can state what kinds of music you're listening to :D

It is just my opinion. If they are willing to do so and feel happy the Intruder, I will just feel happy for them :D

Please PM me your email address. I just dont want to quote/link to a third party cristism here :D

I guess you dont really need balanced output for your IEMs. I have a Rx MK3-b as well and it produces noisy hiss with my W4s. The Intruder worked fine with IEMs, but not really better than my Protector or Predator.

Not really, are you willing to pay $300 for a cmoy if you feel like it sounds better than a $300 amp? ;)

I don't want to dig deeply into technical aspect, but if you look up about the Intruder in some more technical websites, you will see what I mean.This is what I'm technically looking for in a mid/high-end portable amp And again, I have no negative comment at all regarding the sound of RSA...

It is a nice sounding amp, but IMHO, just overpriced. I would never pay ~$700 again for something like this

Absolutely. The W4 even sound good with my 4 year old laptop's sound card :D

I've owned the W4 for half a year and tried them with some dac/amps, from the really cheap to really expensive one. And the only amp that made the W4 sound better than directly plug into my computer is the RSA Intruder, which is $700. I don't recommend it at all. Just get the W4 and try them...
