Pros: I have the old 5.1 Logitech x-540 70 watt speakers. And I'd have to say this sound card does indeed turn my "ordinary PC speakers into a TYPHOON OF SOUND", like it says on the front of HT Omega's webpage. And I don't mean that it makes it louder. This is pretty much the first time I wholly agree with a corny advertising phrase of any product. I am still amazed that my old $90 speakers are able to sound this good. I am no audiophile, but the clarity, seperation, and definition of sound is pretty unmistakable here. I do have some FLAC audio files as well as low bitrate mp3s, and somehow, even the highly compressed ones sound loads better. The win7 driver and software is pretty straightforward. It has that old, 90s interface look but works beautifully and I love it. I also love that this is pretty much the only high-end soundcard that still comes with full surround analogue 3.5mm output jacks. I can't wait to upgrade to 500W 5.1 speakers with optical inputs next.

Cons: None really. Maybe price?

Overall Review: My other choices were Creative X-fi Titanium HD and Asus Xonar Essense STX. But they didn't have analogue surround output for my 5.1 speakers which only had analogue inputs. When I get better speakers with optical inputs, I'll be curious to see how the Claro II compares with the others. But for now, I am very happy.

Pros: The overall exterior design is better than the z5500 The Control Unit is an improvement over the z5500's

Cons: What it boils down to is that the z906 is a much cheapened version of the z5500. It is not really a "successor" to the z5500 as Logitech would like you to believe. Study the specs, the components used in each system(especially the amps), or just listen to both systems side by side. It will become overwhelmingly obvious that there is no chance in hell the z906 should be priced anywhere near the z5500. Yet, Logitech assumes that it can profit by duping people to believe the new system is an equal, or, even an improvement, over the z5500. I'm not just bashing Logitech for no reason. I have used and love their mice, webcams, and speakers(z5500, x540). I just can't accept with a clear conscience their pricing and advertising/marketing of the z906.

Overall Review: I have yet to see a positive review of these speakers from people who had previously owned the z5500. It irritates me to see people praise this product by comparing it to a 80-90 dollar 5.1 channel system simply because they don't realize that Logitech has made an inferior product that costs way less to manufacture(but maybe looks better) and decided to sell it for more money than their old, better product all the while acting as if it is an upgrade in order to hide the simple fact that it is a considerable downgrade. Logitech had an awesome product and had a chance to reinforce their position as a top-quality computer speaker manufacturer. But instead of improving on the few issues of their great product(such as the notorious failure rate of the z5500's control unit), they decided to join the many companies seeking to profit not by means of quality, but by means of cost-cutting and deceptive marketing. I am greatly disappointed in the z906, but even more saddened by its pric

Pros: What more can I want? looks classy, clean, simple, and sturdy works well so far with little noise modular cabling is awesome efficiency is awesome packaging is awesome

Cons: price is not cheap, but you get what u pay for.

Pros: I love these memory modules. They are the best looking of its class. setup was super easy with xmp profile. works very well as intended with no overclocking.

Cons: none.

Pros: works as intended with no heat issues

Cons: none

Overall Review: since I basically never use the hd4000 graphics or overclock, I might have done just as well with the cheaper Xeon server equivalent. Oh well...

Pros: I use it on my Ivy Bridge i7 and it provides good cooling with very little noise even during hours of gaming. I don't intend to overclock, so it will probably never go into higher rpm modes. May be overkill for my use.

Cons: None for me
