Audiophiles take note: The external DAC, amplifier and battery for the iPhone 4/4S of the V-MODA

Audiophiles who also a special class of people who love high quality sound equipment. These users will impose the maximum requirements as to equipment and to the premises for listening to audio frequencies. In an industry such technique is called Hi-End and made small-batch or individually, often by the audiophiles.

 

So for lovers of high-quality sound, rotated by an ideal, "right" sound, which are part-owners of mobile phones Apple - iPhone 4 and 4S - new company aims V-MODA. A device called VAMP combines three functional blocks: a digital-analog converter (DAC), a stereo headphone amplifier and battery.

External DAC and amplifier enable us to obtain much higher quality sound than the one that gives full-time digital code converter to an analog signal. S / N ratio does not drop below 95 dB. Amplifier power is 150 mW per channel (at load impedance 32 ohms).

 

Structurally, the V-MODA VAMP is a hard case for smartphone, the capacity built-in lithium-ion battery, which is 2200 mA ∙ h The kit also includes a cable USB. There is a volume control and switch to a two-tiered stage, the gain, as well as the quality of the switch (Pure or VQ). To connect to an external amplifier gadget comes with an optical output. The cost of V-MODA VAMP program's website is $ 650.

New ARM mali-450 GPU for future Android mainstream

From ARM comes confirmation of a further new GPU called mali-450 MP to be exploited  in the near future  of mid-range devices replacing the excellent mali-400 MP. Same clock as the previous generation, but doubling of cores that will arrive at 8 in the 450-MP scalable.  solution that declaration of ARM will double the performance compared to the edited version of Galaxy S2 and align the overclocked version of Galaxy S3, with the difference that can in turn be clocked by the manufacturers to have a greater increase in performance.

 

Regarding the high end of ARM devices will rely on the known T-604 and T-658 that unlike mali-450 MP will support OpenGL ES 3.0. For 2014, a further evolution of high-end graphics card with a GPU, codenamed "Skrymir" of which nothing is known except that it will replace the T-6xx.

Good news then for those who purchase a terminal in 2013 (timing theory about the first devices to take advantage of the new gpu) mali-450 MP-based architecture. This fact will provide for some good graphics performance with mid-range devices.
