I think I’ve mentioned this before, but I’m getting to the age where repeating myself is just a byproduct of continued existence, so bear with me. A few years ago, I put together a document for new SoundStage! Network writers titled “The Unassailable, Unimpeachable Guide to Writing the Perfect SoundStage! Review (in my opinion, man),” created with the goal of walking newbies through the inner workings of my twisted mind when I’m reviewing a piece of gear.
In that document I said: “At least once a month, I get an email from a reader that effectively boils down to, ‘Should I buy this amp or that one?’ And more often than not, what they’re asking me is akin to, ‘Should I join a monastery or open a clown-themed sex shop?’ The products they’re shopping for are so radically different that they barely belong in the same category.”
That observation popped into my head as I was sitting down to review Vincent Audio’s new SV‑500MK hybrid integrated amplifier (US$1699.95, €1399)—for a few reasons, actually.
I’m going to hold my tongue on the question of whether the SV‑500MK is more a holy sanctuary or a proprietor of marital aids for Juggalos. That’s not relevant. But I will say that I don’t think it’s made for the same person who’s considering, say, a Marantz Model 60n (US$1600, CA$2200, £1299, €1499) or NAD C 700 V2 (US$1999, CA$2499.95, £1499, €1699)—both of which are in the same ballpark as the Vincent piece in terms of price—because they’re playing very different sports.
So what sport is the SV‑500MK playing? Who is it for? I think it’s for the audiophile who is naturally a bit suspicious of all the modern conveniences and topologies but still wants some modern connectivity. Designed in Germany and unapologetically manufactured in China, the SV‑500MK is—much like its predecessor—a hybrid integrated amp with one 12AX7 and two 6N1 tubes (both user-replaceable) in its input stage, and a solid-state class-AB output stage, relying on discrete circuitry instead of integrated circuits.
Whereas the original SV‑500 leaned hard into line-level connectivity—with support for four stereo RCA sources in addition to its coaxial and optical digital ins—the SV‑500MK adds an HDMI ARC port and Bluetooth connectivity, but has only two pairs of line-level inputs, labeled S1 and S2.
The DAC chip has also been upgraded to one supporting 32‑bit/384kHz PCM, although the manufacturer of said chip is unspecified. Output is rated at 50Wpc into 8 ohms and 80Wpc into 4 ohms, with THD specified as <0.1% (1kHz/1W) and SNR reported as >90dB.
All of these specifications, by the way, are wrapped in a chassis that you’re either going to love or hate—love for its straightforward, retro-by-default, “I’m a piece of stereo gear” aesthetics or hate because of its less-than-polished edges and lack of modern touches. Personally, I fall into the former camp, and I could only love this thing more in terms of looks if it had VU meters and a little window through which to see the glow of its tubes.
Setting up and dialing in the SV‑500MK
For the most part, setting up the SV‑500MK is a straightforward affair, as you’d expect. No screens to contend with. No bass management to finagle. No network connectivity. The most complicated part of the entire process for me was getting Bluetooth connected, as I realized what was required to get the thing into pairing mode was either a lot of patience, or simply holding the S3 button on the remote (that’s shorthand for Source 3, I think) until the input indicator light blinks.
As with many technical specifications, Vincent Audio isn’t exactly forthcoming with Bluetooth connectivity details, assuming, I suppose, that its customers don’t care (and maybe they don’t!), but I’ll say this: querying PipeWire via the Terminal in Pop!_OS revealed that my computer was connected via aptX HD.
And the included Bluetooth antenna is the beefiest I’ve seen in some time, so Vincent didn’t half-ass it on the BT front. When I switched to my iPhone 16 Pro Max as a Bluetooth source, its range reached all the way outside of my home, and when compared against all the dedicated Bluetooth receivers I’ve tested for Wirecutter, I found that its range was bested by only one of them: the now-discontinued iFi Audio Zen Blue V2.
Since the SV‑500MK doesn’t feature a phono stage, I didn’t include my turntable as a source in my evaluation. Instead, I relied mostly on my Oppo BDP‑93 universal disc player, connected via a Monoprice 1419 TosLink cable as well as a Monoprice HDMI cable; my new custom-built PC running Pop!_OS 24.04 LTS with Cosmic Desktop 1.0.14 connected both via Bluetooth and via my iFi Audio Zen One Signature DAC using USB‑B; and my iPhone 16 Pro Max connected via Bluetooth.
Since there wasn’t any form of bass management to evaluate, I listened through my Paradigm Studio 100 v.5 tower speakers, connected via a pair of SVS SoundPath Ultra speaker cables, for the duration of this review.
How does the SV‑500MK perform?
Digging into this review, I was curious to investigate the mysterious upgraded DAC first, so I began my in-depth testing by comparing my CD copy of Joanna Newsom’s Have One on Me (Drag City DC39OCD) against the streaming version of the same (16‑bit/44.1kHz FLAC, Drag City / Qobuz), the former coming out of my Oppo BDP‑93 to the SV‑500MK’s HDMI ARC input (and sometimes TosLink) and the latter from my PC into the iFi Zen One Signature DAC and then into S1 of the Vincent integrated.
With “You and Me, Bess,” I could pick up on the subtlest of differences between the two at the upper extremes of my hearing acuity, leading me to suspect that Vincent is employing some sort of slow-rolloff reconstruction filter here, but it’s a graceful rolloff, if I’m correct in that. Exceedingly graceful. Quite pleasing, in fact, in its almost imperceptible injection of warmth. It might not be my first choice, and if I’m right, it’s not technically correct, but Vincent Audio isn’t doing anything stupid with the filtering here, and I like the resulting sound, which is what matters first and foremost.
Via either source, I heard many of the characteristics that I loved in the original SV‑500. But I’d be lying if I said that in re-reading my original review, I wasn’t skeptical of my own impressions. I’ve learned a lot since 2021. Or, goodness knows, I hope I have. And I’ve learned to be even more suspicious of any perceived audible differences between amps.
But there’s just no denying that with this song—this entire album, in fact—the Vincent had a textural quality that was just lovely. The clacky resonances and mechanical sounds of Newsom’s Lyon & Healy pedal harp leapt out of my speakers. Her faint mouth noises and the distinctive timbres of the trombone and trumpet that come in around the 1:44 mark had a tactile palpability, and the soundstage was something to swim in more than listen to.
Skipping to the next track, “In California,” I was blown away by not only the textures but the transients of each plucked string. The attack of each note. The so-subtle-you-could-easily-miss-it sound of Newsom’s tongue disengaging from the roof of her mouth after the T at the end of “heart” in the first line. Little details like that really stood out through all of my listening.
When I loaded up my CD copy of Andrew Bird’s Echolocations: Canyon (Wegawam Music Co. WEG 003) and the streaming version thereof (16/44.1 FLAC, Wegawam Music Co. / Qobuz), my observations were very similar. With the first track, “Sweep the Field,” there’s a delicious sense of space created by the hash of the flowing and burbling water captured in the field recordings. But it was the intro to the fourth track, “Antrozous,” that really caught my attention.
It sounds to me as if Bird is hitting his violin strings with some sort of stick or hammer in this one, and—at the risk of sounding like a broken record here—the textures and timbres of each attack were quite lovely and more than a little accentuated through the SV‑500MK.
Of course, the amp giveth and the amp taketh away. Or maybe I should have leaned on the old cliché about no free lunches. Either way, the cost of such enhanced textures and timbres is that the SV‑500MK’s bass performance can be uneven.
With “Blue Sky” from the Allman Brothers Band’s Eat a Peach (24/96 FLAC, Mercury Records / Qobuz), one note of the bass line would punch through the mix with exceptional authority and weight, whereas the next would be relatively swallowed by the rest of the music.
One reason I rely on this track as a reference is that its bass line plays around in the territory where my Paradigm towers have a decent dip in their impedance, and I could really hear that dip with the SV‑500MK. Again, everything I love about the amp’s sound rang true here: the textures of the acoustic guitars were gorgeous. The saturation of Dickey and Duane’s guitar amps was unmistakable. Overall detail was just incredible.
On the other hand, the uneven bass performance was a bit distracting for me. But I strongly suspect that another speaker with different electrical characteristics would reveal unevenness at different frequencies that might not be revealed with this song.
So what’s going on here? I suspect it’s not a current issue, since the amp has a good power supply. And it’s got oodles of capacitance. That leaves me thinking that it might be an issue of output impedance being a little high, and as such the damping factor a little low. But given that Vincent Audio doesn’t publish these specifications, I can’t be certain about that.
Either way, the only go-to music for me that consistently sounded less-than-stellar through the SV‑500MK was largely electronic stuff—Massive Attack, Sneaker Pimps—the sort of music that many audiophiles have zero interest in. And, again—this needs to be reiterated—this observation was a consequence of the interaction between the amp and my speakers. A speaker with greater sensitivity and less of a roller-coaster impedance plot may well sound much more balanced when paired with the SV‑500MK, so that’s something to consider.
On the upside, whether via my computer or my iPhone, the Bluetooth connection sounded absolutely fantastic, and I could happily listen to my favorites all day long via this maligned wireless connection. Again, signal strength was fantastic, and sound quality was as good as it gets with BT, in my experience.
I was also impressed by the headphone output, which drove both my AKG K361 and Audeze LCD‑2 headphones without a bit of a problem. Plugging in a set of cans auto-mutes the speaker outputs (not always a given with boutique-y gear like this), although I did have to turn the volume up past the 50 percent mark with the Audezes, and there’s no volume memory, so you might need to remember to roll the volume off a little before unplugging your cans. The headphone output is noise-free, detailed, and well-balanced, with output to spare, which makes a dedicated headphone amplifier all but unnecessary unless you have some insanely thirsty headphones.
What other integrated amps should you consider in this price range?
The Marantz Model 60n I mentioned above sells for pretty close to the asking price of the SV‑500MK, and while it lacks the Vincent’s tubes, it does have more analog connectivity and similar digital connectivity, but also adds a network connection. It also has a little more output at 60Wpc into 8 ohms (still 80Wpc into 4 ohms, though). In my experience with the amp, it’s not as influenced by the speaker’s impedance swings. Then again, its vibes are of the exact mass-market sort that I would imagine Vincent Audio fans are trying to avoid. So it’s tough to find much meaningful competition for this one.
TL;DR: Is the Vincent Audio SV‑500MK worth the money?
There’s no doubt that this hybrid integrated amp has its quirks. The fact that the remote control only handles source selection, volume control, and muting—not power—might bother some folks. And, perhaps biggest of all for me, the fact that I could hear my speakers’ impedance swings at reference listening levels (much less so at lower listening levels, to be fair) definitely gives the amp the sort of sonic personality that most solid-state amps these days simply don’t have.
But that might be exactly what you’re looking for, and I’m not going to tell you you’re wrong. The enhanced detail and textures afforded by the amp—again, connected to my specific speakers—were undeniably captivating.
Whether or not you’re going to dig the SV‑500MK probably boils down to the sort of music you dig. As with its predecessor, soul and Motown, jazz, avant-garde freak folk, prog, and whatever the heck Andrew Bird could be classified as all sounded incredibly delicious. EDM, big beat, ’90s pop, and some hip‑hop didn’t fare quite as well.
Different horses for different courses, or so they say. But in a weird way, that sort of makes the SV‑500MK kinda special. There aren’t many amps I can think of that have distinctive sonic fingerprints. This one does. That may be exactly what you’re looking for in your sound system. And if it is, I’m glad a solution like this exists.
I still wish Vincent Audio would give us a little window through which to view the glowing tubes in its input stage, because in my estimation, the look of tubes is the coolest thing about them. But hey, maybe the company is holding that back for the SV‑500MK2, or whatever it decides to call this guy’s inevitable successor.
