A Case for the iPhone 4s being and competent DAP

Nathan has a review of the iphone 4s as a DAP on Headfonia.  He makes the case that the 4s is a very competent DAP and should be one of the options considered when looking for $0-$500 DAPs.  He compares the 4s’ technical capability with that of the Cowon Plenue D and the AK Jr.  An interesting read.

JH Audio & Astell&Kern Siren Series Full Metal Jacket Line Announced!

Jude over at Head-Fi just posted a video of the updated JH Audio Siren Series IEMs.  Included in this video is the updated Layla, Angie and Roxanne.  Unfortunately, Jude doesn’t provide side by side reviews with their prior versions since he just received the units. The new Rosie 6 driver IEM was also announced along with a small review from Jude.  The Roxanne obtained an additional crossover standardizing the 10-12 driver models to a 4-way crossover.  I assume the new Rosie is a 3-way since it only had three groups of drivers. The Layla now has a titanium housing will all of the other Sirens are made from aluminum. All of the models now have new cables made by Moon Audio. No discussion on any improvement to the SQ but the connectors have upgraded.

I state that this is an update and not an upgrade.  The only changes on the Layla and Angie were the housing which I don’t feel is an upgrade.  Since the audio travel through the same stainless steel waveguides the change in housing material should have little to no impact on the SQ.   I suppose the additional crossover in the Roxanne might be an upgrade but we won’t know for sure until we receive some side by side comparisons.

Headfonia has a very in-depth review of the AK380.  I think I will stick with my 240.

New Astell&Kern Beyerdynamic IEM

AK has partnered with Beyerdynamic on a new IEM (AK T8iE).   This single-driver (per-ear) design uses dynamic drivers which is an identical configuration to the Sennheiser IE800.  No impressions yet but I will post them once they come in.  BTW, the price point is $999.



Astell & Kern’s Junior

Here is a good review of the new AK Jr. DAP.  The unit was released with mostly positive reviews but the firmware needed tweeking.  From numerous posts on Head-fi the UI was sloth like.  The good news is that a firmware release was just made available with apparently improves UI performance.  Here’s the review:
