All in Digital

The AVM Ovation CS 8.2 All in One

Some forty or more years ago, the average person who set out to buy a stereo system, typically ended up with a stereo receiver. Things were much simpler then; all you needed was a receiver, a turntable and a pair of speakers. As for ‘audio furniture’, milk crates were the order of the day. A pair of included patch cord interconnects and if you were somewhat sophisticated, a run of heavy gauge lamp cord and you were in business. You didn’t have to give any thought to power cords, because components had captive power cords. 

Of course, there were serious hobbyists who bought separates and had furniture grade cabinets made to house their components and speakers. These folks constituted a very small minority of stereo buyers. Once the transistor era took hold, watts per channel was the order of the day; the bigger the box with more knobs and lights, the better. 

Mojo Audio Deja Vu Music Server with Linux, Roon, Tidal, and HQPlayer Software

Five years ago I began using a music server and DAC in lieu of a compact disc player, thus starting my journey into digital audio streaming. Keeping in mind that music servers are in fact computers, my main motivation came from discovering Mojo Audio, a company which at the time modified Mac mini computers to be serious music servers by (among other changes) replacing their internal power supplies with Mojo's own high-end external linear power supplies. Over the last 5 years I have kept the Mac mini as my reference, only upgrading it by changing player software from JRiver to the revolutionary Roon Labs, subscribing to Tidal, and swapping out its power supply by a series of better ones—all made by Mojo Audio, too; currently I use their Illuminati V2—it is a ‘choke input’ power supply and is my favorite [my review of the V1 may be found here].

But five years is a long time in the digital world. Much has happened. I did see and listen to various new alternatives including NUCs (‘Next Unit of Computing’ mini-computers) which were smaller, lighter, typically less expensive, and more energy efficient than a Mac mini. Like a Mac mini, a NUC is ‘headless’, e.g., you do not need to connect a monitor or keyboard to it except for setting it up with software and such. Once set up, controlling music play is accomplished by using a wirelessly connected app on a mobile device or tablet. I also checked out serious commercial high-end music servers, and I have been impressed at times. Suffice to say it has become clear that the Mac mini is on the way out; there are quite a number of alternatives.

PS Audio Sprout100 Integrated Amplifier

In February of 2015, I reviewed the original PS Audio Sprout, the brainchild of Scott McGowan. It was a powerful, small, simple to use stereo integrated amplifier with DAC, analog preamplifier, headphone amp, phono stage, Bluetooth receiver and more; I was dazzled by its performance at $799. Now we step forward 3 years to the second generation for review here: the Sprout100—at only $599.

I ran into McGowan recently at the Rocky Mountain Audio Fest in October 2017, where he pulled out a prototype of the Sprout100 from his backpack at the hotel restaurant for my perusal; my eyes lit up at what I saw—and hoped to hear soon after. As I will try to convey in this review, some serious thought by McGowan was clearly given to this new version, and by drawing upon the expertise of PS Audio’s engineer Darren Myers, PS Audio has produced a product of exceptional value—and substantially better than the original. 

Mytek Brooklyn DAC +

Digital Analog Converters (DAC) in recent years are achieving better and better sound quality, with some getting smaller and lighter that, yes, can still be considered of audiophile/high-end quality both in sound and construction–and at a lower cost than one might think. Some of these newer smaller DACs have a variety of integrated features from among volume control, a preamp for analog input, headphone amp, phono stage–and even amps and streaming, in some cases. This trend is yet another example in high-end audio, where the meaning of ‘integrated’ has been expanded to describe any audio unit that incorporates several functions for your audio system.

Certainly a prime example of this progress is demonstrated by the Brooklyn, New York based company Mytek, which, in mid-October 2017, released the object of this review, the new and improved Mytek Brooklyn DAC +. I am grateful to Mytek President Michael Jurewicz for promptly sending me a unit for review.

I had spotted the DAC + at the recent RMAF 2017 (Denver Colorado, early October) in the lobby with Jurewics, where it was being debuted and was sufficiently impressed to accept his offer of reviewing it. As a Manhattanite, naturally I was initially interested in reviewing the much more expensive Mytek Manhattan II DAC; but the tiny size, lower price, and extraordinary array of included technology in the new Brooklyn DAC + truly intrigued me.

Naim Audio Uniti Atom All-In-One System

Naim Audio is one of the high end companies we have begun to take for granted. Founded back in 1973 in beautiful Salisbury, Wiltshire by the late, aristocratic Julian Vereker MBE, Naim Audio has become synonymous with the very finest in modular and single components and loudspeakers. A true legacy company of our avocation. British audio royalty. 

With the company's success, the vibe has become a little more corporate, a long way from the beginning where Vereker would shout from the rooftops the benefits of beautiful, if austere, design and the unending benefits of power supplies (the more, the merrier).  

I have been a huge fan of Naim Audio almost since its inception. I heard my first Naim products in London way back in the late 70s/early 80s when I was studying music there. Along with Cyrus, Arcam, Rega Research, Audiolab and others, Naim Audio began making its name producing very high quality components, eschewing the huge box, huge power, American high end audio design philosophy. You got the MG/Spitfire/Austin Healy power/design acumen, but with reliability. I remember being thrilled with an Arcam integrated with a whole 25 watts per channel, and loving it. 

PS Audio Stellar Gain Cell DAC

When my publisher informed me he had made arrangements with PS Audio to do a review of their latest DAC and that I would have the good fortune to do the review, I was interested. My Audiophilia colleague, Karl Sigman, is very high on their products and having heard them at his lovely abode I was looking forward to the arrival of their latest offering.

The Stellar series is comprised of the DAC and a choice of two amplifiers: the S300 stereo amplifier and a pair of S700 Mono-blocks.

As it turns out, the DAC is not only a DAC but a full function preamplifier making it the center piece of a system with remote control operation. It’s quite a package.

Comparing the DAC of the PS Audio Stellar with my reference DEQX HDP 4 processor proved to be challenging. For those of you who are unaware of what the DEQX can do, suffice it to say it offers the ability to greatly modify and alter the sound through its speaker and room correction capabilities. It also allows you to let the signal go through without any modification — that is the way I use it.

SONOS PLAY:1 Loudspeaker; 5.1 Surround Sound; Stereo Pair

It would be instructive to read my original review of the full SONOS system [PLAYBAR, SUB, PLAY:5]. 

This review will examine the addition of two PLAY:1s to that superb system. The PLAY:1 is the smallest SONOS speaker at (USD) $199.00 /each. They will be auditioned as rears converting my main floor lifestyle system into 5.1 surround sound. I'll also add my thoughts with the PLAY:1s setup as a standalone stereo pair. 

Devialet Phantom

Devialet (pronounced: duv’-ē-a-lay) is the Parisian company that has created a Sonos-like stir in the audiophile world. Its ‘pizza box’ shaped, flagship product, the D200, is an amp, preamp, phono stage, DAC and WiFi card in one very thin, sexy chrome box. The audio press went wild over it. I heard one at length just recently and it casts a pretty spell on the music and is a top notch, one-stop shop. If that's what you’re after.  

Mojo Audio Mystique DAC v2.0

I usually bump into Mojo Audio’s Ben Zwickel at the industry party the night before the Rocky Mountain Audio Fest in Denver. It’s becoming a tradition. Zwickel gets us as many drink tickets as allowed then the rest of the evening is wine, more wine, dinner, and then even more wine, interspersed with stories of the year’s audio adventures. Let’s just say he’s ‘energized’.

The SONOS Wireless Music System

A few things have revolutionized the music business in the past decade — Apple's iTunes, mobile audio on smart phones with the headphone boom, followed this year by streaming audio. What was missing in the lifestyle mix was a quality delivery system for the home. One that worked easily, sounded great and was reasonably priced. Sure, Bose had a big lead. ‘Good’ sound for the masses but at a high price. The high price paid for the marketing, which was quite effective.

PS Audio DirectStream (DS) DAC

PS Audio recently released (March 2014) a new DAC to replace their already top-notch, high-end PerfectWave DAC (PWD), which I reviewed about a year ago, with a follow up review using it with the PerfectWave Bridge which enables using an ethernet cable to stream the digital files from computer to DAC instead of USB. The PWD, using ethernet, has become my reference DAC ever since. So, when I heard about this new one, I licked my chops at a chance to try it out on my system and review it.
