ASUS has announced two new products for their Republic of Gamers lineup today, and while we saw the Matrix GTX 980 Ti at IFA in September (and the Maximus VIII Extreme/Assembly was also on display), there are further details for both products in today's press release.
ASUS ROG Maximus VIII Extreme/Assembly motherboard with Matrix 980 Ti
The motherboard in question is the Maximus VIII Extreme/Assembly, a Z170 board with an external headphone amp and 10Gb/s Ethernet add-in card included. This board could run into some money.
The ROG 10G Express expansion card
While other Maximus VIII series motherboards have high-end audio support, the Extreme/Assembly further differentiates itself with an included 10Gb/s Ethernet card. ASUS has partnered with Tehuti Networks for the card, which in addition to 10Gbps also operates at conventional 100/1000 Ethernet speeds, as well as new 2.5/5Gbps over CAT5e.
“ROG 10G Express is the enterprise-speed Ethernet card, powered by Aquantia® and Tehuti Networks: these key partners are both members of the NBASE-T™ alliance, and are working closely to create the new 2.5Gbit/s and 5Gbit/s standards that will be compatible with the existing Category 5e (Cat 5e) cabling and ports. With PCI Express 2.0 x4 speed, it equips Maximus VIII Extreme/Assembly gamers for next-generation LAN speeds of up to 10Gbit/s — or up to ten times (10X) faster than today’s fastest onboard consumer Ethernet.”
This will certainly add to the cost of the motherboard considering a 10GbE card (without the 2.5/5Gbps feature) currently sells for $239.99 on Amazon.
The ROG SupremeFX Hi-Fi amplifier
If you’re an audio enthusiast (like me) you’ll be impressed by the attention to audio, which begins with the audiophile-grade ESS E9018K2M DAC chip found on other members of the Maximus VIII family, and capable of not only native PCM 32-bit/384kHz playback, but up to dual-rate DSD (DSD128). The external headphone amplifier features the Texas Instruments TPA6120A2, and has a very high 6V output to drive the most challenging headphone loads.
What about the Matrix GTX 980 Ti? Full specifications were announced for the card, with boost GPU clock speeds of up to 1317 MHz.
- Graphics Engine: NVIDIA GeForce GTX 980 Ti
- Video memory: 6GB GDDR5
- CUDA cores: 2816

Just the look of the EF100 DAC from HiFiMAN gives you the notion that this is not an entry level peice of audio equipment, it is aimed at those who desire near studio quality audio but who lack the means to rent studio time or buy professional level equipment. The $500 price tag is steep but you get what you pay for, a tube driven amplifier with C-Media CM102s inside with two analogue inputs, a mini-jack and RCA inputs. If this sounds like something you might need in your life check out TechPowerUp's review right here.
"HiFiMAN has a reputation for producing great headphone amplifiers. Today, we take a look at their newest do-it-all headphone amplifier & DAC combo with an on-board T-amp. This all-encompassing device features a class A/B headphone amplifier with a tube input stage. Despite all its features, it sells for $499, which is quite impressive."

Introduction: Improving Portable Sound
The Calyx PaT is very small USB DAC and headphone amp that can be used with PCs and mobile devices, offering the possibility of better sound from just about any digital source. So how does it sound? Let’s find out!
The PaT is a very interesting little device, to be sure. It rather resembles a large domino and weighs less than 1 ounce thanks to an ultra-light aluminum construction. It requires no battery or power source other than its micro USB connection, yet it provides sufficient power (0.8 V output) for in-ear monitors and efficient headphones through its 3.5mm headphone jack. Inside is a proprietary mix of DAC and amplifier circuitry, and like other products produced by Calyx, a Korean company with little presence in the United States, there is the promise of a dedication to great sound. Did Calyx pull it off with the diminutive PaT?
Improving Portable Sound
Outboard DACs and headphone amplifiers for computers and mobile devices are nothing new, with recent products like AudioQuest’s Dragonfly a prime example in the portable USB DAC market (though it offers no mobile support). When I first heard about the PaT during CES it was still in the prototype stage, but I was interested because of the Calyx name if nothing else, as I already owned the Calyx M DAP and had been quite honestly blown away by the sound.
So what need might I have for the interestingly-named PaT (pronounced "paat", meaning "bean" in reference to the small size), which is itself a DAC that requires another device to play music files? It wasn’t until I had the opportunity to speak with Calyx president Seungmok Yi during CES (via video chat as I couldn’t attend the show) that I started realize that this could be a compelling product, not just for the $99 price tag - a bargain for an audiophile product - but because of how versatile the PaT can be. You don't have to identify as an "audiophile" to appreciate the clearer and more detailed sound of a good DAC, especially when so many of us simply haven't heard one (especially on mobile devices).

For the audio enthusiasts at CES this year Calyx Audio (Korean maker of audiophile-grade audio components) has a new prototype to show along with last year's Calyx M music player, and for an audiophile product the pricing is very aggressive.
Render of the Calyx PaT (dimensions in mm)
The PaT is a similar product in some ways as Calyx Audio's existing $199 USB DAC called the "Coffee", but this unit will be much smaller and will cost half as much at $99. And the reduction in price and size is only half of the story as the PaT also works with mobile devices as an outboard DAC/headphone amp. Apple iPhones and iPads will be supported, and Android devices with USB audio-out support as well (probably via USB OTG).
The PaT supports up to 16-bit, 48kHz files (AIF, M4A, PCM, OGG, and MP3) and will also control track playback and volume via hardware control buttons on the unit. The PaT requires no external power or battery, taking what little juice it needs directly from the connection to your mobile device. As for amplification, in typical Calyx fashion even this miniature board is using a discrete class A/B headphone amplifier. Since the PaT relies only on the power passed through the USB connection it is only capable of outputting 0.8 V, which by comparison is slightly lower than an iPhone 5 which outputs about 0.9 - 1.0 V.
The tiny prototype PaT in action
The PaT may be just a working board at this point, but the company has scheduled the release for February 2015, when the devices will be available in various colors of thin aluminum enclosures.
In the world of computer audio much more attention has been focused lately on advancements in sound, with special shielding and isolation on motherboards, special gold-plated USB ports for DACs, and customizable op-amps a trend. While the market for dedicated sound cards isn't what it once was, high-end PCI-E and USB cards from Creative (Sound Blaster) and ASUS (Xonar) are still widely available. Most of these products are for desktop users, but there is a growing number of portable devices that allow mobile users to experience great sound, too. For myself, great sound means faithful reproduction of 2-channel music, and it's nice to see attention paid to that area without the added effects of digital signal processing (DSP). Calyx seems interested only in engineering products that play back music as close to the source as possible, and I can't argue with that!
The Calyx PaT is scheduled to launch in February for $99, but like most high-end audio components it will take a little research to track it down. The USA distributor of the Calyx brand has a website with product and contact information here.

Tagged: usb, Portable Audio, headphones, Headphone Amp, DAC, D/A Converter, Cirrus Logic
Creative has added a new member to their portable Sound Blaster "E" series lineup with the E5.
This new multi-function DAC and headphone amp features a reference-grade D/A converter chip from Cirrus Logic, the CS4398, which supports up to 24-bit/192kHz PCM audio (and technically DSD 2.8MHz/5.6MHz, though this does not seem to be implemented here). In addition to the realistic analog reproduction possible from a high quality chip like the CS4398, the Sound Blaster E5 provides amplification via a Texas Instruments TI6120A2, which Creative says gives the E5 a "best-in-class 600 ohm headphone amplifier".
Another aspect of the E5 that sets it apart from the previous E1 and E3 models is the inclusion of optical digital input/output, to go along with USB and dual 3.5mm headphone jacks. The two 3.5mm jacks can simultaniously drive two pairs of headphones, and on the back of the unit there are additional 3.5mm jacks for microphone input, line input/output, and these double as optical input/output via mini TOSLINK. (This might be geared for portable use, but would serve as a fine external sound solution for desktops as well!)
The input stage of the E5 uses another Cirrus Logic chip, the CS5361, enabling high quality recording options from various sources at up to same 24-bit/192kHz. While supporting external microphones (as well as line/optical input) the E5 also has "built-in beamforming CrystalVoice microphones for audio recording and calls". And while the E5 is employing Creative's SBX sound processing chip, this DSP can be switched off with a button on the side of the device - a welcome option for serious music listening from high-resolution source material.
The Sound Blaster E5 also supports digital input from iPhone and "select" Android phones (listed compatible devices include the Samsung Galaxy S4/S5, Galaxy Note 2/3, and Nexus 5/7). For portable use the E5 has a built-in rechargeable 3200mAh lithium polymer battery, which Creative says will provide up to 8 hours of playback per charge.
The Sound Blaster E5 will be available in October for $199 at Creative's online store (and likely various other retail outlets).

The Diamond Xtreme Sound XS71HDU could be a versitile $60 solution for those with high end audio equipment that would benefit from a proper DAC. With both optical in and out it is capable of more than an onboard solution, not to mention the six 3.5-mm jacks for stereo headphones, 7.1 surround support with rear, sub, side, mic, and line in. The design and features are impressive however the performance failed to please The Tech Report who felt that there were similar solutions with much higher quality sound reproduction.
"We love sound cards here at TR, but they don't fit in every kind of PC. Diamond's Xtreme Sound XS71HDU serves up the same kinds of features in a tiny USB package suitable for mini-PCs and ultrabooks. We took it for a spin to see if it's as good as it looks."

If you go out and buy a high end pair of headphones and plug them into your onboard audio you are essentially doing the same thing as buying a 4K monitor and plugging it into onboard video; sure it will work but you certainly won't get the full experience. For audiophiles a Digital Analog Converter, specifically a headphone amp is required to actually hear what your earphones are capable of. Using the XMOS XS1 TQ128 USB decoder, a TI PCM1798 Digital/Analog Converter and the famous TI NE5532 Op-Amps the specifications of this headphone amp are quite impressive as is output impedence of less than 1 ohm on a connection rated to handle up to a 600 ohm load. If you recognize any of those components then head to Benchmark Reviews for the full article.
"The Silverstone EB01–E DAC is the companion product in both form and function to the SilverStone EB-03 headphone amplifier. Together, these two components make up the current SilverStone Ensemble Series audiophile grade audio components."
