For some time it's seemed there is no ideal compromise for gamers that are also audiophiles. Creative Labs has been a leader in sound for gaming, but not in music. Other brands boasted superior audio quality but lacked EAX and strong hardware acceleration. Auzentech seeks to change that in their new Prelude 7.1 model card.

The card promises the fusion of audiophile sound quality and all the gaming perks one would otherwise miss out on by skipping Creative. Auzentech has been a contender in quality musical sound cards for years, up there with M-Audio and ASUS.

The Card At A Glance

Pros

o High-end DAC (digital to analog converter) at 120dB signal to noise ratio

o Supports up to 7.1 output via analog

o SPDIF ports support digital-in/out via coaxial and optical

o Dolby DTS

o Full EAX 5.0 support

o 64MB X-RAM (like Creative's higher end X-Fi's)

Cons

o Uses a modified version of Creative's drivers rather than something unique

o Lacks external breakout box (as compared to Creative's X-Fi Elite)

Features

The Prelude offers comparable features to the Creative X-Fi Elite Pro, but at a smaller price tag. It does, however, lack the breakout box the Elite Pro comes with for desktop headphone out and a further way to handle SPDIF. The Prelude tries to compensate for this by offering better SPDIF connectivity natively on the card, though.

The back panel of the card starts with a mic jack, followed by a line in. From there you have your front/main out, and two others for rear and surround. Of course if you're not looking to use 5.1/7.1 you need only be concerned with the front/main jack. All of the aforementioned jacks are 3.5mm. Two final ports are identical in appearance-digital input and output respectively. These support coaxial SPDIF in/out by default, but the card comes with adapters that convert them to optical ports if needed.

Performance

Bearing Creative's X-Fi processing chip, the Prelude should offer the same performance in games and maintain compatibility with any that use EAX 5. It has the analog auxiliary pins onboard, and a somewhat toned down version of Creative's drivers to make it all happen.

Because it uses a form of Creative's drivers, users familiar with that software will appreciate the three flexible output modes: Entertainment, Gaming, and Audio Creation.

The card itself is notably larger than the X-Fi Xtreme Gamer, likely due to the extended output options. This does guard against the feeling of a stripped down product, as the Xtreme Gamer card is more of an entry-level item on Creative's X-Fi lineup. This card serves as an excellent alternative to Creative's Elite Pro for users not interested in the breakout box and hoping to save cash by doing without it.

All in all this card is feature full and again, a great alternative to Creative for gamers. Still, the card does not bring anything special to the table for the serious audiophile like the ASUS Xonar, for example. That card offers a built-in headphone amp and EMI-shielded coaxial outputs. Touches like that would truly have brought the Prelude 7.1 a league above the Creative.

Stainless Steel Art World(1)- Stainless Steel Sculpture

As a special kind of alloy material, stainless steel could created astonished vivid artworks when applied in metal molding technics, it also has aesthetics advantages when used in art design.

Many stainless steel indoor artworks have a large number of detailed designs, these details’ realization require a mass of forging and machining work, stainless steel are rich in category and it’s a good choice, in this kind of application, stainless steel are more popular than those alloys who have higher  rigidities.

 

Based on traditional Chinese culture, China’s stainless steel artwork adopted European art style, created unique and lively works, these works sometimes are beautiful, vivid, and amazing a lot of people..

Stainless Steel Sculpture

In many a years, many great carving artists are favorite to use stainless steel to create art works, for its special structure and unique aesthetics value. As great sculpture artist Albert Paley said ”Stainless steel could created astonished vivid artworks when applied in metal molding technics”; "Stainless steel are advantaged in machining, molding and connecting productions, it could also keep the whole structure completely, is a clean and ideal material”’ "Compare with stainless steel with bronze, I prefer to use stainless steel to create large-scale works, because bronze’s structure integrality is inferior to stainless steel”.  

 

 

Adopting stainless steel are need not to paint, also have no use for covering, it can display the metal itself and its fine plasticity, furthermore, to an artist, stainless steel’s special reflection quality is also very important.

"We use satin faced stainless steel stead of lightless coarse one, part of reasons are to prevent the interference caused by reflection. Stainless steel has a subtle reflection quality, it will help outstands the production’s art impression, outdoor sight works need such effects especially. Passing through the exchanges of lights and shadows optic fibers could create a sort of vigor, while satin faced stainless steel, it seemed that the lights are come from the material itself, as if the lights was absorbed by the material and then been reflected out, thus make the whole work clear and transparent, lively and vivid, especially evident in cloudy sky”.

 Supplemental Remarks:

 

Mr. Paley is one of the most well-known and the most welcomed artists in world, who is famous as creating large-scale stainless steel sculptures. For example, the sculpture sitted in Rochester Technology Institute is weighed 100-ton and 21-meter high. Mr. Parley usually used S31600 steel and anti-weather steel, they not only have great corrosion stability and maintenance free, but also strong enough to support large-scale pieces of work.  

Sheeted stainless steel are used in decoration or large-scale sculpture commonly, for it has more machining difficulty, generally applied in productions with huge bodies, which could taken on the beauty characters of industry era.

Entangled Photons - Cheapest?

Can anyone tell me the cheapest way to get a pretty reliable continuous source of entangled photon pairs?

So far all I can find is $15,000 US for an experimental setup with BBO crystals.
This was back in June 2002 and I'm sure there's been quite a bit of progress since then.

I recently heard about a source using twisted optical fiber but can't find the reference.
