EVGA has announced a brand new product offering for enthusiasts, but this PCI Express device is not a graphics card - it's a premium sound card. And yes, I know that many people have written off audio boards in the era of ubiquitous motherboard audio, but if you are at all interested in quality audio and have ever looked into external DACs and headphone amps the Nu Audio card is shaping up to be a fantastic alternative to external component solutions.
The product is a result of a partnership with UK-based Audio Note, a high-end audio equipment manufacturer that emphasizes technology and internal component quality in their designs, and the design of the Nu Audio card was made to those standards. EVGA says that is the pursuit of life-like sound that inspired this card, and their efforts have resulted in something that would be completely at home in an audiophile setting, RGB effects notwithstanding (yes, it has RGB!).
Ok, so what is this exactly, and why is it any different from other PCIe sound cards? This is not your typical DSP-driven surround audio solution, and truly the emphasis is on 2-channel stereo audio reproduction. Reading over the specs this begins to look more like an audiophile product, with native DSD support and PCM audio up to 24-bit 384 kHz - and dual clock generators for native 44.1 and 48 kHz-based sample rates. Component choices were made to improve audio quality through the signal chain and to the output, with some impressive specs:
- DAC: AKM AK4493
- ADC: AKM AK5572
- OP-AMP (Headphone): ADI OP275
- OP-AMP (Line Out): ADI AD8056
- Capacitors: WIMA, Audio Note(UK), Nichicon
- Power Regulators: Texas Instruments TPS7A47/TPS7A33 ultralow-noise power solution
The demo in the EVGA suite featured a nice setup featuring some of the entry-level Audio Note components, showcasing hi-fi music playback from lossless files on a PC. It was quite impressive considering the sound card was fed directly into the integrated amp, and on display were also such features as separate analog control of the volume output (the internal amp can be controlled independently of the sound level in Windows), and the integrated RGB lighting that dynamically respond to music playback.
The Nu Audio sound card will retail for $249 when it launches, specifics on release date to follow.

The least expensive pairing in this review will run you £5,194 and the most expensive doubles that, not the audio source and cables whose prices leave Monster green with envy. Kitguru has taken on the high end of headphones and amps, leaving even those $1000 studio headsets far behind. Each has their own usage, when you are spending this much on equipment they tend to be very specialized; usable in all scenarios but best served for what they were designed for. Check out the review to laugh, cry or in some cases feel jealous of equipment you might actually want for some reason.
"This article today is focused around the synergy between amplifier and headphone and the four setups I have chosen for this article are to my mind some of the best that money can buy. There is about £70,000 of equipment on test today."

If swappable op-amps, an Objective DAC for proper analog sound and a frequency range of 10hz - 19Khz not only makes sense to you but gets you a bit hot and bothered, JDSLabs has an interesting product for you. Built around the open source Objective2 amplifier this pre-amp and DAC is designed to attempt to produce professional quality sound without the price tag attached to that level of gear. The suggested price is $285 which might seem high for a headphone amp but is actually much less expensive than professional level kit. TechPowerUp were very impressed with the quality of the sound and the tweaks possible to make to the DAC but thought that perhaps a bit more thought could have been put into the aesthetics of the device.
"JDSLabs's O2+ODAC combination combines two designs by NwAvGuy with excellent build quality and a sturdy enclosure. The O2+ODAC sells at just $285 which, performance considered, is a bargain. We test whether this amplifier and DAC combination is really the giant slayer it is made out to be!"

Elitegroup Computer Systems (ECS) recently announced its support for the new AMD Memory Profile (AMP) technology. The A85F2-A Deluxe will be the first of the company’s motherboards to support AMP.
AMP is AMD’s version of Intel Extreme Memory Profiles (XMP) which amounts to known-safe automatic overclock settings. The AMP profiles are stored in the DDR3 memory modules and can be read by supporting motherboards. Now knowing the proper voltage, CAS latencies, and timings to use, the motherboard can ideally automatically configure the modules to run at optimal speeds.
The setting will be able to be enabled/disabled in the BIOS of the new ECS motherboard, as shown in the screenshot below. According to its press release, ECS is the first company to integrate AMD Memory Profile support into its motherboards, and it is honored to lead the charge. “Making a unique and glory prominent product is the only purpose for ECS.”
Here’s hoping the implementation works well and is more accurate than my experience with XMP profiles has been! Will you be using AMP in your AMD builds?

During this morning's keynote at the AMD Fusion Developer Summit, Microsoft's Herb Sutter went on stage to discuss the problems and solutions involved around programming and developing for multi-processing systems and heterogeneous computing systems in particular. While the problems are definitely something we have discussed before at PC Perspective, the new solution that was showcased was significant.
C++ AMP (accelerated massive parallelism) was announced as a new extension to Visual Studio and the C++ programming language to help developers take advantage of the highly parallel and heterogeneous computing environments of today and the future. The new programming model uses C++ syntax and will be available in the next version of Visual Studio with "bits of it coming later this year." Sorry, no hard release date was given when probed.
Perhaps just as significant is the fact that Microsoft announced the C++ AMP standard would be an open specification and they are going to allow other compilers to integrated support for it. Unlike C# then, C++ AMP has a chance to be a new dominant standard in the programming world as the need for parallel computing expands. While OpenCL was the only option for developers that promised to allow easy utilization of ALL computing power in a computing device, C++ AMP gives users another option with the full weight of Microsoft behind it.
To demonstrate the capability of C++ AMP Microsoft showed a rigid body simulation program that ran on multiple computers and devices from a single executable file and was able to scale in performance from 3 GLOPS on the x86 cores of Llano to 650 GFLOPS on the combined APU power and to 830 GFLOPS with a pair of discrete Radeon HD 5800 GPUs. The same executable file was run on an AMD E-series APU powered tablet and ran at 16 GFLOPS with 16,000 particles. This is the promise of heterogeneous programming languages and is the gateway necessary for consumers and business to truly take advantage of the processors that AMD (and other companies) are building today.
If you want programs other than video transcoding apps to really push the promise of heterogeneous computing, then the announcement of C++ AMP is very, very big news.
