    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). ...

    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. ...

    The Auralic Aries is one of the most highly anticipated products in recent memory. From the moment it was announced as a wireless DXD and DSD capable component with USB output to today, the Aries has remained high on many peoples’ lists of components to audition. Fortunately I’ve been able to audition the Aries for several months. During this audition many software and firmware updates were released and the product continued to improve far beyond its initial capabilities. For example, users of the Aries requested USB disk playback and Auralic delivered the feature through a firmware update. Based on my experience with the Aries it’s completely understandable why the product remains very hot among members of the Computer Audiophile Community. As of today the Aries and corresponding Lightning DS app deliver on all Auralic’s ...

    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. ...

    Rarely do I hear a component that's truly a game changer, a component that's so good I can't stop listening through it, and a component that's so good it renders much of the competition irrelevant. I can't remember, off the top of my head, the last time I heard such a component. That is, before the Berkeley Audio Design Alpha DAC Reference Series arrived. The Alpha DAC RS, every bit a true game changer, blew me away from the first listen in my system. Since its arrival I've listened to more complete albums and heard more new sounds from old albums than any time in my life. The Alpha DAC RS is so good and such a game changer it may force consumers to reconsider their desire for high resolution music. Sure the Alpha DAC RS can reproduce high resolution music better than any DAC I've heard in my system, but its absolute magic can be heard with standard CD quality 16 bit / 44.1 kHz material. The Alpha DAC RS is without question the best DAC I've heard anywhere when it comes to 16/44.1 playback. I've never heard detail, delicacy, and transparency with my favorite music like I have when listening through this DAC. The Alpha DAC RS is so outstanding that I equate its presence in my system to that of a new pair of loudspeakers. That's correct; the Alpha DAC RS had an impact on my system equivalent to a new pair of loudspeakers. In fact, the Berkeley Audio Design Alpha DAC Reference Series is the most remarkable sounding product I've ever reviewed. ...
