    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 ...

    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. ...

    The Oppo HA-1 is a harvester of many tricks, so many in fact that it is almost unfair to label it strictly a headphone amplifier as the acronym in the name suggests. It really stretches the boundaries of inputs, outputs and digital conversion all within a reasonable amount of desktop real estate.

    As with all things Oppo, attention to detail appears to be a top priority, even down to the packaging. In a market where the focus on sound quality can allow manufacturers to slip by with off-the-shelf interfaces and external design, the Oppo ship is watertight. In rare form for most HiFi equipment, the head amp includes a fully interactive graphical interface, complete with pretty icons for source selection. Connectivity is king with the HA-1. Nearly every single base is covered. In the rear you can find super DSD-friendly USB, single ended ins and outs, balanced XLR ins and outs, and one of each type of available digital input (including optical, coaxial and AES/EBU). To top it all off Oppo included both an in and out trigger and Bluetooth connectivity with aptX. An external remote is included, but in case you don’t want another one lying around the house, Oppo even has a remote app for your perusing pleasure that connects via Bluetooth. ...

    (Computer Audiophile Contributor Ted Brady completes his thorough review of the Chord Qute HD / EX with this final update. I don't think there is anyone in the industry with more insight and time spent with this DAC than Ted. His original review of the HD and two updates can be read HERE. Below is Ted's wrap up with incredibly high praise for the EX. - Editor)

    I have owned the Chord Qute EX (aka EX) now for a couple months (arrived Feb 10) and wanted to wrap up my feelings about this DAC; i.e what is different about it from the HD I reviewed above, and what additional information or impressions I have of the Qute DACs since last writing about them. ...

    T+A Elektroakustik is a company for which some Americans have yet to acquire a taste. Yet, T+A's product styling, build quality, and sound quality have won numerous awards throughout Europe. It took me awhile to really get what this company was doing and to acquire a taste for these German designs. At CEDIA 2013 I told the Dynaudio North America team, importers of T+A, that the styling of the T+A components was less than pleasing. Then I was shown a "custom integration" rack full of T+A components and things started to click. The look of this tall rack with several uniform looking components was quite nice. Since the CEDIA convention T+A components have entered my mind several times, especially when considering Ethernet streaming devices. T+A isn't new to the streaming audio market. The company's engineers have been perfecting its streaming platform for years and know quite a bit more about this technology than many companies. One of the first questions I ask before reviewing a streamer is, does the product support gapless playback at all sample rates? The response I received from T+A at RMAF was priceless. The answer, "Of course." I felt like gapless high resolution playback was an issue T+A conquered last century and the company was on to solving more complex issues. After acquiring a taste for T+A's styling and hearing about the company's impressive product engineering surrounding audio streamers, it was time for me to get the Music Player Balanced into my system and start listening. ...
