    I'm starting this review from a unique point of view. I purposely learned very little about the product under review before I started my listening sessions. I know the product is a DAC manufactured by Hegel and it says HD12 DSD on the front panel. I skimmed through the user manual to find out how to enable 24 bit / 192 kHz PCM and DSD playback and at the same time learned it's recommended to use the balanced analog outputs. Other than this information I have no clue how much this product costs, what DAC chip (if any) it uses, or where Hegel positions the DAC in its lineup of products. I don't know if I have an entry level or a flagship DAC. I even disabled the LED display on the unit while listening so I was looking at a small black box that gave me no visual cues that could sway my sonic impressions. Sure, I could have hired an assistant to unbox the DAC and place it behind a curtain until I wrote this review but life is about balance and I think I found a good balance between knowing everything about a product and not knowing anything, including how to use the product. I'm not a fan of blind testing audio components, rather I just wanted to have a little fun while reviewing this component and try writing from a different perspective. In a way I feel like a consumer entering an audio store without too much knowledge and looking for a DAC. The person at the store has told me to have a listen to this product from Hegel and we'll discuss the details after I'm done listening. With this in mind here are my sonic impressions of the Hegel HD12 DAC, followed by some information about the product (that I must look up after writing about my sonic impressions). ...

    My office consists of an iMac 5K retina, Macbook Pro, iPad, Google Nexus 7, and my iPhone 6+. All of these devices either contain or stream audio that I listen to while working. Whether it’s Internet radio, audio books, TIDAL HIFI, or podcasts I prefer to listen to the audio through my main audio system, which fortunately is also in my office. The question for me is always, how do I get the audio from any of my devices to my stereo system as easy as possible with the best quality possible? One answer to this question is the Audioengine B1 Bluetooth Receiver. The B1 is all about balance between convenience and quality. The convenience offered by a Bluetooth connection is currently second to none. There are no WiFi networks or passwords to worry about. Simply tap connect on a device on that’s it. On the other hand, there’s no getting around the fact that Bluetooth is currently a lossy way to stream audio. But, using the aptX codec companies like Audioengine have increased the quality of these lossy streams greatly. aptX has moved Bluetooth audio from barely acceptable into the realm of highly desirable under the right circumstances. ...

    There’s no question Devialet builds beautiful products. From the moment one opens the box it’s easy to see this company is the Apple of HiFi. Unboxing a Devialet amplifier is like opening a present to oneself. Beautifully packaged, the amplifier comes out of the box with an absolutely perfect mirror finish to the chassis. The same can be said for the one of a kind remote control. Right from the start my experience with Devialet was luxurious. I can see why Devialet has become a media darling and why the press has unanimously drooled over everything the company has released. Are the products that good or are the stunning looks and unique design fooling everyone? I set to find out, first with the Devialet 200, then with a pair of Devialet 400 monoblocks. ...

    PS Audio DirectStream DAC, a chameleon in the high foothills, by Ted Brady

    This has been the hardest review to write, for many reasons, not the least of which is that this DAC took me on a journey that seemed, at times, like a wild goose chase. But here we are, and if you, the reader, are like so many others, you'll go the end and find that this goose chase resulted in quite the golden goose.

    By now most of you know that this DAC is the brainchild of one Ted Smith, a longtime developer/designer/wunderkind who had been dabbling in this DAC design for over 10 years. Two major problems existed during that time: first, the technology didn't exist to do what he wanted; and ...

    The wild world of DACs continues to expand with a new update from the pro-leaning company Grace Design. The m903 was released just 3 years previous but already it seems like a (product) lifetime ago. The newest bible-sized, DAC/headphone amplifier is called the m920 “High Resolution Monitoring System” and still shares many of the same external design elements from its predecessor. The internals have had some renovating of course, and the price moved $100 north from $1,895 to $1,995. As of September of this year the m903 is permanently discontinued so older models aren’t kept around for purchase like the Benchmark DAC 1 series or a previous generation iPad. ...

    Please enjoy this terrific article by member of the CA Community, Steven Rowan.

    In my 40 years plus of audiophile life, it's not often that I have discovered, listened to, purchased, and lived with a family of electronics, that have transformed my listening room as I thought only a multi thousand plus turntable, tone arm, and Koetsu cartridge could do. In my experience only a top rated analog system had the power, realism, and magic to enthrall one into believing they are at a live event instead of sitting in their listening room. Of course the digital siren had tried to dethrone my analog rig but couldn't quite succeed. Such contenders as Yamaha, Oppo, Theta, PS Audio and even the legendary Mark Levinson Reference Digital products were quite moving and enjoyable and had tried to supplant my record spinner but couldn't quite close the gap. Until now. And this is how it went down.

    Even though I loved my analog rig, I couldn't ...
