VINCENT SV-700/DAC-1
Integrated amplifiers
Alike the Vincent SV-238 Mk that we reviewed few years ago the SV-700 is an amplifier beast. It weighs 25kg and its heatsinks get really hot after thirty minutes indicating that its Class A topology is not only a paper statement. And yes, there is a glorious round window on the amplifier’s aluminum fascia that lets you see glowing tubes inside.
Funkce a forma
The Vincent SV-700 is a hybrid amplifier that combines a solid-state power stage with a vacuum tube preamplifier in one chassis, all fed by a 500VA toroid. The tube compartment hosts 1x12AX7 and 2x12AU7 per channel. By push of a button a user can select whether the SV-700 should run in Class A (consuming 350W at idle) or in more environmentally friendly Class AB. Sonically the AB is not an option – the Class A operation was audibly better in all parameters. The tax you pay is slightly less of power: in the Class A the SV-700 provides 2x 50W into 8 ohms, in the Class AB 2x100W, or 2x200W into 4 ohms respectively. All signal paths are strictly symmetrical from inputs to outputs. The SV-700 offers 4 analog inputs (3x RCA and 1x XLR) plus 2 digital inputs for a built-in DAC (optical and coaxial), 1 line output and 1 regulated preamplifier output.
Should your primary source of music is represented by a streamer or a NAS storage, the Vincent DAC-1 will be become your first choice upgrade. The SV-700’s built-in DAC (up to 24bit/192kHz) is a decent performer, the DAC-1 is a completely different league however. And the combination of the SV-700 and the standalone DAC-1 gives fantastic price to performance ratio leaving most competitors far behind. I loved the combination of the two so much that I had decided to review both devices as a pair.
Nízké frekvence
One cliché says that tubes are friendlier to human ears than transistors and it holds true here – the vocal of Lisa Gerrard was very present in the room and supporting percussive rhythms were punchy and solid (Dead Can Dance, Into The Labyrinth). Another cliché says that tubes are soft, colored and smeared. I cannot disagree more. Through the SV-700 the percussions had very good balance between transient attack and high mass sound pressure followed by clean trailing off. The SV-700 can provide punchy and dynamic rhythms also in Forest Runners (David Arkenstone, Citizen of The World) and if I should compare its presentation to category peers I would say it is above average.
Čistota rozlišení
Take a simple yet very difficult song like Walk The Dinosaur (Flying Pickets, Inak). This vocal arrangement can be sweet and dynamic but also very nasty and flat. Not every amplifier or speakers can handle the layers of sounds that are built toward the finale of the track – the SV-700/DAC-1 combo can do this with aplomb. It lets you navigate inside the arrangements and lets individual voices shine even at high listening volumes.
I also liked the Vincents when listening to Nicola Benedetti’s Vivaldi suite (Decca) – the transition between the digital zeros and the ambient silence of a recording venue was delight to hear, as well as the first very dynamic stroke of the violinist’s bow. The very same recording played through Accuphase E-270 integrated that I had on hand during this review was a bit veiled and too soft.
Tonální věrnost
The Vincent is open at the top end with a slight tilt towards leaner tonality, yet it is a superbly clean amplifier and so the extra oppeness never becomes sibilant. On the contrary it helps soft transient sounds stand out as if they were carved by a chisel. The whole presentation of the SV-700 is lively with a great sense for rhythm and timing.
Prostorovost
There is a lot to admire about the SV-700 but if I should single out one parameter where the Vincent excels it would be soundstaging. It throws a very wide and deep soundstage with point-to-point imaging precision. Big orchestras were spatially very resolved and I could identify easily from where a xylophone sound came from, which player got restless on his chair or the moment of a bow touching string. The soundstage was very natural without any inclination towards being ´U´ or ´V´ shaped. It is not flat but all the members of the orchestra are easily traceable within a rectangular stage.
The soundstage resolution is changing when switching between the A and the AB mode – the Class A gives you better 3D illusion, airiness and orchestral color saturation, plus improved transparency and more relaxed rhythmical drive. There is no real reason why to stay in the Class A other than paying less for electricity. If I should compare the Vincent combo to the Accuphase E-270 there is no way the latter can win despite it is more expensive. I highly recommend the SV-700/DAC-1 to any serious audiophile. For the money paid (3.500€ amp and 700€ DAC) it is a bargain.
