A former editor at a now-defunct magazine has been posting away on LinkedIn about the demise of luxury audio, how it has no market, how its elderly consumers are a dying breed, and other assorted observations that mostly reflect his own alienation from the higher end of the high-performance audio marketplace. Little of what he claims has any basis in fact, though none of us deny that there are trouble signs ahead for <\/i>manufacturing of all kinds due to global conditions generally and roadblocks like raw material availability and tariffs specifically. One loudspeaker manufacturer I know, unable to obtain magnets from overseas, had to suspend production for months. That is not helpful for remaining in business!<\/p>\n

One of this individual\u2019s most recent and hilarious posts was, \u201cI\u2019m old enough to remember the days when you shopped for stereo gear by picking it up and deciding if it was appropriately heavy.\u201d Does anyone reading this remember ever buying stereo gear by weight? I don\u2019t. Not even Julian Hirsch recommended that method. Of course, I was approaching middle age when this individual was born<\/i>, so I can go back way further, and I never<\/i> remember anyone shopping for hi-fi by weight, though unfortunately many do buy audio gear based on price\u2014as in, if it costs more it must be better.\u00a0<\/span><\/p>\n

However, his post reminded me of some seriously \u201cweighty\u201d audio gear I\u2019ve reviewed over the years, one of which was Gryphon\u2019s Apex Stereo power amplifier, which is at the extremes of both audio heaviness and at almost three feet long, audio length. Fortunately, no stairs were involved in getting the big black behemoth in or out, though experienced piano movers were nonetheless required to facilitate both. Also fortunate is that while Gryphon\u2019s recently introduced two-chassis Siren Phono Stage is unusually large and heavy, unlike the Apex it does not weigh 445 pounds!\u00a0<\/span><\/p>\n<\/div>\n

The Physical Plant And The Contents Therein<\/h2>\n

Siren arrives in two large break-down crates, one for the 83-pound power supply that\u2019s as heavy and large (appx. 19\u2033 x 9\u2033 x 18\u2033) as many powerful stereo amplifiers, and the other for the nearly as large, 67.5-pound signal-processing chassis. Like all Gryphon products, the Siren presents itself as an imposing-looking, brooding black entity, wholly appropriate for the sculpted gryphon that holds court atop the chassis. The power supply, featuring an attractive vertically arrayed, curved, mid-section grille is identical to the one supplied with the Commander preamplifier<\/a>, and here\u2019s the good news for owners of that formidable piece: its power supply is ready to supply the $44,800 Siren. Owners of other preamplifiers will have to add $33,700 to power their Siren, which shares the Commander\u2019s 4.3\u2033 hardened-glass-panel, TFT\u00a0capacitive touchscreen. For weight-based buyers, Siren plus a separate power supply is an easy choice. Those with other considerations will have to read on!\u00a0<\/span><\/p>\n

The Dual-Mono PSU offers what Gryphon says is a \u201cpower reservoir whose size and quality are unprecedented in a phono preamplifier\u201d and features local, fully regulated power supplies for all sensitive voltage-amplification stages, plus a discrete one for each channel, and a third specially engineered supply for all digital \u201chousekeeping\u201d functions that keep the digital and analog circuits separate all the way back to the AC cords.<\/p>\n

Siren sports quad-layer PCBs with 70\u00b5 copper traces that Gryphon claims are twice the thickness of the competition\u2019s. High-quality parts include Mundorf MCap ZN capacitors, Vishay low-inductance resistors, matched ROHM transistors, and ultra-low noise ones from ZETEX. The RIAA circuit uses tight-tolerance Vishay polypropylene capacitors and Vishay SMD precision MELF resistors. Pickering low-capacitance SIL reed relays ensure smooth and quiet input and load switching.\u00a0<\/span><\/p>\n

Sensitive audio circuitry floats on a proprietary internal isolation base featuring constrained damping layers of Kerrock, bitumen, and steel, designed to eliminate sonic smearing of fine detail. Capacitors are particularly sensitive to vibrational energy.<\/p>\n

The dual-mono-configured circuitry features zero global negative feedback in a fully discrete, fully balanced circuit topology that Gryphon has employed in its phono preamps for more than 30 years. Internal wiring is kept to a minimum. Gryphon uses specially selected PC-mount XLR and RCA jacks. There\u2019s more, but that\u2019s probably enough!<\/p>\n

User-Friendly Features and Operational Sophistication<\/h2>\n

Siren offers four voltage-gain-based inputs: three balanced XLR and one single-ended RCA. There\u2019s a single pair of balanced XLR outputs. Each input can be set for moving magnet with gain settings of 38dB or 48dB and 12 capacitive load settings for moving coil with gain setting choices of either 68dB or 58dB and an unusually wide range of load settings (24) between 20 ohms and 1600 ohms, plus three capacitive load settings. The chosen settings for each input are stored in memory.<\/p>\n

From the attractive, machined, black-anodized aluminum remote you can select inputs, adjust resistive and capacitive loading, mute the output, and adjust display lighting. Step away from the front panel, and after a few seconds the screen defaults to the selected input in a large easy-to-see number. Get close, and it automatically defaults to a screen that displays settings and allows access to a menu where you can make other adjustments, including setting gain and naming the inputs. Gryphon\u2019s claim is true that muting and switching between inputs and between loading and gain settings are accomplished smoothly and noiselessly.\u00a0<\/span><\/p>\n

DarTzeel Watt Meter Goes Wild!<\/h2>\n

I ran three cartridges to assess the Siren\u2019s sonics, all on the Wilson Benesch Prime Meridian turntable<\/a> (same as the company\u2019s GMT minus the active pneumatic suspension): the Wilson Benesch Tessellate Ti-S ($11,500) on the Graviton Ti arm, the Hana Umami Black ($11,500) on the SAT CF1-12 arm, and finally the Gryphon Audio Black Diamond DLC ($20,000) on the Graviton arm. Both the Umami Black and Black Diamond were reviewed on Tracking Angle<\/i>. Though the Black Diamond was reviewed on a relatively inexpensive ($3469) Ortofon AS-309R arm, the arm and the cartridge produced sonically spectacular results. The DLC resembles the Ortofon Diamond, upon which it is based, but it has a very different sound that\u2019s richer and more fully fleshed out.<\/p>\n

The Graviton\/Black Diamond DLC combo was, I\u2019ll say upfront, sonically monumental<\/i>.<\/p>\n

But first, the Siren may be the least fussy phono preamplifier I\u2019ve encountered regarding ground hum. There was none with all three cartridges and without paying particular attention to ground wires, though of course the single-ended SAT connection featured a secured ground wire. The complete absence of hum and noise even with volume way up rivaled the black backgrounds of the CH Precision P10 and HSE Swiss Masterline 7 that I reviewed here and Jacob Heilbrunn reviewed for Tracking Angle<\/i>\u2014and purchased. Though the HSE\u2019s noise spec is considerably lower, the Siren had a similarly notable, ultra-low-noise presentation that went beyond an absence of \u201chiss\u201d to a sonic place where, on great recordings, layers of low-level detail lurking in the backdrop became clarified (even to older, not-noise-free ears).<\/p>\n

As with any highest-of-quality phono preamplifier, the cartridge\u2019s tonal characteristics called the tune here, but the Siren\u2019s macrodynamic presentation on dynamic peaks were off the charts huge<\/i>. I\u2019ve never seen the watts scale on the darTZeel 468 amps hit the peaks (and differential peaks) I saw (and heard), even on solo piano records, which for some reason is where I started the serious listening, beginning with the Nimbus Records 45rpm Super Analog Mastering Shura Cherkassky Frederick Chopin Piano Recital<\/i> (Nimbus 45021) a studio recording that has \u201croom ambience\u201d that may or may not be artificially enhanced. Doesn\u2019t matter. I played this one at the Warsaw Audio Fair (naturally), and audiences went wild (almost literally). I played the \u201cBallade No. 4 in F minor, Op.52,\u201d and, as the annotation notes, Cherkassky played it with \u201ca considered and matured interpretation of muscularity and power.\u201d\u00a0<\/span><\/p>\n

Dynamic contrasts both large and small helped produce as natural a flowing presentation of this record as I\u2019ve heard here or anywhere; the smallest scale microdynamic gestures were delivered with a convincing and relaxing ease, facilitating the pianist\u2019s most subtle ideas. I wasn\u2019t particularly listening for that, but they made themselves obvious and helped to both communicate the pianist\u2019s musical and emotional intentions and solidify listener engagement.\u00a0<\/span><\/p>\n

The Tessellate\u2019s somewhat stingy and dry lower midrange character and upper-octave clarity and speed were easy to identify, the Umami Black\u2019s generous spatial presentation and upper-midrange generosity were on full sonic display, and especially well-presented was the Black Diamond DLC\u2019s overwhelmingly rich yet well-textured harmonic structure and its detailed expansive scale\u2014almost brutal as Cherkassky dug into the keys toward the piece\u2019s conclusion. It felt like the piano was going to explode!<\/p>\n

Readers familiar with the tongue-in-cheek Harmonia Mundi album La Folia <\/i>wherein conductor Gregorio Paniagua takes the Atrium Musicae De Madrid on an off-kilter Spike Jones-like ride through 17th<\/sup> century Spanish\/Portuguese dance music, punctuated by an exploding bottle of cognac, the conductor\u2019s \u201cBocinetta Peugeot\u201d musical quotes from Mancini\u2019s The Pink Panther<\/i>, and an Indian raga, know the Harmonia Mundi version (HM 1050), but there\u2019s also a special audiophile edition on the German ATR Master Cut Recording label (ATR 013 LP) that takes the transparency, dynamic range, and soundstaging of the already spectacular original to hyper-extreme levels of spatial and dynamic scale. I used the record as part of a review of a moderately priced high-performance Luxman E-07 phono preamp, and I thought I had a handle on the record\u2019s extreme sonics, but wow! Through the Siren it was another level of extreme.<\/p>\n

Though the Gryphon was sensational on all three cartridges, the Black Diamond DLC\u2019s delivery was something else entirely: The soundstage filled and overwhelmed the space where the Wilson Audio Chronosonic XVX speakers sat, seeming to break down and obliterate the side and front walls; the stage was huge, extending alarmingly close to where I was seated, and the speakers seemed to not be playing at all, replaced instead by a gigantic fibrillating musical bubble that you could inflate to gargantuan size by turning up the volume with no loss of musicality, and remaining free of even the slightest hint of edginess or mechanical interference. This was a rare-for-a-veteran reviewing thrill. If you know and love the Harmonia Mundi original try to find this one!<\/p>\n

A test pressing arrived the other day by surprise from The Electric Recording Company. Owner Pete Hutchison\u2019s handwritten note said, \u201cI think you could use this test pressing of John Martyn\u2019s Solid Air<\/i> we\u2019ll soon announce.\u201d The original U.K. Island is a favorite, and on this ERC took the great-sounding original Island to another sonic level. Again, the Siren communicated each cartridge\u2019s essential character, putting each in a most positive light with an effortless sense of non-mechanical musical flow also free of electronic artifacts. Natural, unforced attack, sustain, and decay and timbral neutrality that allowed each cartridge to express its subtle but notable personality.\u00a0<\/span><\/p>\n

The recorded sound by John Wood at Sound Techniques is warm and full, aided by this edition\u2019s all-tube vintage cutting system, yet Martyn\u2019s voice never blended into the studio warmth and always presented itself cleanly distinguished from the room, with a full sense of body attached to head, his guitar equally clear yet warm and dynamically expressive. Clapton\u2019s cover of Martyn\u2019s \u201cMay You Never\u201d is familiar to most everyone, but the original here is more sweeping and insistent, and I doubt Clapton would disagree. The record through the DLC was visceral and powerfully communicative.<\/p>\n

The times when I thought maybe the sound through all three of these cartridges was a tad \u201crich\u201d was always destroyed with a record on the bright and hard side that sounded so. I figured the Siren was too full-bodied especially via the DLC to do justice to PiL\u2019s Metal Box<\/i>, highlighted by Jah Wobble\u2019s room-shaking dub bass lines and Keith Levene\u2019s migraine-inducing (in a good way) hard-edged guitar, but no! Instead, the Siren\u2019s song was right on the sonic money, only more intensely delivered both in bottom-end depth and weight and chalk-on-blackboard edge. Best of all you could just keep turning the volume up and up and up, and it only got better<\/i>!<\/p>\n

A lacquer from 1995 of Buddy Holly<\/i> cut by Kevin Gray for MCA\u2019s \u201cHeavy Vinyl\u201d series that I was involved in, sounded as three-dimensional and \u201cyou\u2019re in the studio with Buddy\u201d transparent and alive as I\u2019ve ever heard it. On \u201cRave On\u201d the transparency and quiet allowed a glimpse into the back of the original studio in Clovis, New Mexico, and I was able to distinguish the different character of the overdubs done at Bell Sound in New York. I\u2019ve never heard this so fully exposed and clarified.<\/p>\n

The Siren passed every test I tried to trip it up with. What would happen with Joni Mitchell\u2019s For the Roses<\/i>? On the opener \u201cBanquet,\u201d instead of the overlay of warmth I was expecting, Joni appeared in thrilling three-dimensional relief, standing well in front of the band with no<\/i> added warmth, and behind her the piano\u2019s percussive attack and dynamics were better articulated than I\u2019ve ever heard them. \u201cCold Blue Steel And Sweet Fire\u201d and \u201cBarandgrill\u201d? Never heard them sounding so revealed in three-dimensional space\u2014all of Tom Scott\u2019s reed and woodwind arrangements so clear and weighty<\/i> yet at the same time fully coherent. The dynamic contrasts of her piano throughout the album were greater and more expressive than I can remember ever hearing them, and I\u2019ve been playing this very pressing since 1972, which makes the record-wear business laughable.\u00a0<\/span><\/p>\n

Conclusion<\/h2>\n

As good as all of these cartridges sounded through the Siren and they all surely did, the combination of Gryphon\u2019s Black Diamond DLC cartridge and the Siren phono preamp produced among the best vinyl playback I\u2019ve yet heard on familiar record after familiar record, particularly in terms of dynamic contrasts and harmonic completeness; however vinyl\u2019s dynamic range measures, for whatever reason, it doesn\u2019t sound much greater on any format than I heard from this combination. For the Roses<\/i> was the wrap-up album just to cinch the deal, and what the cartridge (and the Graviton and Prime Meridian) pulled from the record and pushed through the Siren produced the best rendering of that record I\u2019ve ever heard. Took me by surprise. So full and rich, yet detailed and rhythmically agile.<\/p>\n

To cap off the experience I played the Haitink\/BPO Bruckner 7th<\/sup> direct-to-disc record and as Pink Floyd sang, wish you were here. And I wish I could find some fault with how this combo sounded or how the Siren sounded with the other two cartridges, but I can\u2019t. I could go on about some of the other familiar recordings I played through this combo and so greatly enjoyed, but I\u2019m thinking I\u2019ve made the point. \u00a0<\/span><\/p>\n
