Being an audiophile is difficult.
Being an audiophile into vinyl is more difficult.
Being an audiophile who is so into vinyl that you have more than one turntable is bordering on a personality disorder.
Having a turntable is often looked upon as a lot of work by those into digital for good reason: One has to consider drive types (rim, direct, belt, idler, AC or DC motor supply for example), tonearm approaches (gimbal, unipivot, suspended, linear mount) then there’s the cartridge, and the myriad different vagaries of alignment; vertical tracking force, azimuth, anti-skating, vertical tracking angle). Oh, what about suspended vs. non-suspended turntables? Low-mass platters, and high-mass platters? Isolation? Levelling?
Then there’s cartridge choices… moving magnet, moving iron or moving coil?
All this for one turntable… no wonder having two turntables is often looked upon as madness. You’d have to have an obsessive-compulsive disorder just to able to cope.
But since I’m often referred to as suffering from OCD, I took it upon myself to invite a second turntable into my home so that I could test the Dynamic Sounds Associates Phono II. This phono stage that can handle three tonearms/carts or turntables simultaneously, easily switching between them with a press of a button, and with more loading options than any sane person would think to entertain.
The fit and finish of the review unit I received was impeccable, and included detailed, easy-to-decipher nomenclature that laid out the numerous, and complex abilities of the Phono II in a clear, concise manner that wasn’t confusing. This could be an imposing piece of engineering for the uninitiated, indeed, a number of guests in my home commented on the gleaming, polished array of dip switches that adorned the Phono II’s front facia – which are cleverly hidden by a discrete hinged door if you desire – and how complex it must be to operate. Nothing could be further from the truth. Once you’re familiar with implementing your presets for the different carts, or arms, and ‘tables you are feeding it, the phono stage is a breeze to use.
Let’s talk about what exactly the Phono II can do starting with the front panel:
The aforementioned dip switches allow the user to not only set resistive loading for three separate moving-coil cartridge presets from 25 Ohms to 1575 Ohms in 25 Ohm increments, but capacitance loading as well for moving-magnet cartridges from 225pf to 975 pf, and either 47k Ohms or 100K Ohms.
There are very tactile (soft touch) push-buttons that allow for switching between inputs, for adjusting gain values of 40, 50, 60 and 66dB, for engaging standby mode, muting, stereo or mono selection, inversion of polarity, a high-pass or rumble filter, and when in mono mode a button for L-R, and R-L which allows one to compensate for cartridge azimuth alignment. Cleverly included on the underside of the unit (in roughly the centre) is a switch to dim or brighten the bright blue LEDs adorning the chassis for various functions. The unit can also easily be converted to operate on 240VAC.
The rear of the unit has three pairs of RCA inputs, and balanced-XLR inputs as well RCA, and balanced XLR outputs, separate ground terminals for each input, and a chassis ground. A detachable AC mains cable socket is also included so that aftermarket cords can be used.
OK, we’ve established that the Phono II is incredibly well equipped to deal with any cartridge (or cartridges) you might be able to throw at it, but how does it sound?
First off I want to say that my preferred method of loading MM cartridges is with a valve moving-magnet phono stage, and if I’m running a moving-coil cartridge then I use a passive Step-Up Transformer (SUT) into that standard 47K Ohm moving-magnet stage. There are a number of reasons I do this, which I’m not going to get into here, but the main reason I prefer this type of set-up is the quality of the sound; the musicality of the sound. So I have to admit there was bit of healthy skepticism giving up my valves, and SUT to embrace this solid-state approach. Of course this was not my first solid-state phono stage, but it was the first to tip the scales over the $10,000 USD mark (MSRP is $13,500 USD), and put it in contention with some of the very best stages I’ve spent time with. One of the many things I’ve learned in my relatively short tenure with high fidelity is that surprises come fast, and they come despite skepticism. I cannot review hardware, and not have an open mind, and often times being skeptical is a good thing to have a dose of, but one has to be willing to have one’s mind changed, and any doubts I may have harboured disappeared after running-in the DSA Phono II.
There are as many types of sound that a listener can have a preference for as there are listeners to hear the music. Myself? I like the ability of a system to handle big dynamic swings, to have a feeling of limitless headroom, to be fast, transparent, to have speed on transients, and in-the-room realism on tone, and timbre. I also like lots of space around, and between instruments, and voices. The Phono II nailed all these requirements for me.
I started out my listening session after having the Phono II in my system for a number of weeks, and in that time I left in on almost constantly. It got mildly warm to the touch, but other than that it exhibited no signs of anything other than dead silence, and a muted blue glow when the lights went down.
I used two turntables for this review, the first was a Linn LP12 Sondek in Majik guise with a Hana SL low output moving-coil cartridge (0.5mV output, 30 Ohms internal impedance, VTF was set to 2.0 grams, $749 USD), and an Avid Acutus SP with a Koetsu Rosewood Signature Platinum (0.3mV output, 5 Ohms internal impedance, VTF was set to 1.95 grams, $7,495 USD). These cartridges have a markedly different presentation from one another, and in my experience I have found both possess a somewhat narrow band for loading to hit their ultimate sweet spot to maintain a balance that preserves a spacious, airy top end, compelling midrange, and deep, textured bass that both carts are capable of reproducing. I’ve listed the rest of the system used at the end of the review.
- Final playback specifications for the Koetsu were: 60dB with 225 Ohms of resistive loading.
- Final playback specifications for the Hana were: 60dB with 475 Ohms of resistive loading.
I did not engage the High-Pass Filter for any listening sessions.
The album starts with Disorder, and a fiercely percussive, staccato drum line from Stephen Morris that immediately had my body jerking around involuntarily. Peter Hook’s bass line, and Bernard Sumner’s guitar drop in on your nervous system like a car-battery lead shorting out on your skin. Both the Koetsu, and Hana being fed into the Phono II delivered all the coiled tension, and energy of tracks like Insight, She’s Lost Control, and Shadowplay with a real fluidity. Cuts like Day of the Lords, and Candidate are revealed in slowly unfolding entropy, swallowing up your sonic focus with an emotional unease that left me squirming. The Phono II likes to emotionally connect you to the music, a crucial parameter for any analog translator. Throughout the LP, Morris’ drumming had a vicious, snapping edge that was exquisitely resolved as it flitted from the skins, and crash cymbals. The low-level texture of Hook’s bass was rough-hewn, raspy, and gritty with superb in-your-face riffs from Sumner’s guitar that had bleeding-edge speed on every transient. While the decay from cymbal splash, and Ian Curtis’ dissonant vocals didn’t have the last nth of spatial bloom I’ve heard from similarly-priced (or more) tube phono stages like Audio Note UK’s M6, it made up for that with a transparency to source, and conciseness in its realism. This album through the Phono II left me drained, which is exactly what I want when listening to it, because it is a long, turbulent sonic ride, and if I’m not tired after hearing it, then something is wrong.
I listened to literally tens of dozens of albums while the Phono II was in my home, but I’m only focusing on three of them, because I feel that with these three, you the reader, will be able to establish a reasonable baseline for the DSA’s capabilities. I’ve done my best to choose LPs that cover enough sonic territory to give a genuine cross-section of music as well. I don’t only listen to “audiophile” recordings; whether it’s a bargain-bin third pressing, a Japanese Obi-wrap, or a concentious remaster, I listen to everything, and I listen to anything a lot that sounds great to me. Which leads me to my final LP.
The DSA Phono II is an outstanding phono stage simply on the merits of its abilities to emotionally engage the listener in a compelling, transparent, tonally accurate, and ultimately musical manner. The fact that it can do this with inputs for three cartridges/turntables/tonearms only makes its appeal that much more alluring. For anyone who has a turntable with the ability to take on multiple arms/carts, (mono or stereo) or for the audiophile in possession of multiple turntables – or looking to expand their present coterie – this phono stage should be at the top of your list for a home demonstration. You really do have to experience the Phono II to understand how flexible, and accommodating it is with any matter of cartridge loading. While I didn’t have an opportunity to try a moving magnet cartridge with it, the two LOMC carts I used were not only disparate price-wise, but sonically in their presentation. The fact that the Phono II allowed me to almost infinitely dial-in, and tailor their specific loading characteristics allowed me to experiment with the myriad possibilities that alternate loading can have on how a cartridge interprets your record collection.
