The all tube phono stage, done properly
Most phono stages that carry a tube badge are hybrids. A tube sits somewhere in the signal path for flavor, while solid state devices do the actual amplification and, almost always, run the power supply. The PrimaLuna EVO 100 Tube Phonostage V2 takes the harder road. It amplifies your cartridge with tubes, it stabilizes its supply with a tube, and it rectifies with tubes as well. There is no rectifier chip hiding inside. That decision shapes everything about how this unit sounds and why people who love vinyl gravitate toward it.
Look at the tube complement and the design intent becomes clear. Two 5AR4 rectifiers convert AC to DC the way it was done in the finest classic gear, a smoother and more forgiving process than solid state rectification. Two EL34 tubes are not in the audio path at all here. They form a tube stabilized power supply, essentially a regulator that gives the audio stages a clean, quiet, low impedance foundation to draw from. That is unusual and expensive engineering, and it is a big part of why this phono stage sounds so unfazed by dynamic swings.
The signal amplification itself is split intelligently by cartridge type. Moving magnet cartridges are handled by four 12AX7 tubes, a classic high gain triode beloved in phono circuits for its natural voicing. Moving coil cartridges, which need far more gain because their output is so much lower, route through two 6922 tubes. So you are not asking one gain stage to do two very different jobs. Each cartridge type gets a circuit suited to it.
Point to point, no compromises inside
The EVO 100 V2 is wired point to point with premium Swiss wire rather than laid out on a stamped circuit board carrying the audio signal. This is the same build philosophy that has made PrimaLuna a serious value proposition in high end tube gear. Point to point wiring is slower and more labor intensive to build, but it keeps signal paths short and direct and makes the unit serviceable for the long haul. PrimaLuna also builds in power transformer protection, which matters a great deal in a tube component that will be powered up for thousands of hours over its life.
Physically this is a substantial single chassis component. It weighs 27.9 pounds and measures 11 inches wide, 7.5 inches tall, and 15.9 inches deep. The height and mass come straight from all those transformers and tubes. It is offered in silver and black, so it will sit comfortably next to the rest of a PrimaLuna system or blend into a mixed rack.
How it sounds
The EVO 100 V2 has the sonic signature you hope for from a fully tube, tube rectified design and rarely actually get at this level. It is dimensional and unforced. Voices and instruments have body and air around them rather than being etched onto a flat plane. The tube rectified supply contributes a sense of ease on transients, so a hard piano strike or a full orchestral crescendo arrives with weight but without the glassy edge that fatigues you over a long listening session.
Because moving magnet and moving coil have separate, purpose chosen tube stages, both cartridge families sound at home. Moving magnet cartridges through the 12AX7 path come across warm, rich, and tonally generous. Moving coil cartridges through the 6922 path deliver the low level detail and speed those cartridges are prized for, but with the harmonic completeness that only tubes tend to give.
This is not a clinical, hyper detailed presentation. If your goal is to dissect a recording into its smallest particles, understand that the EVO 100 V2 prioritizes musical flow and tone. It shows you plenty of detail, but always in service of the whole performance rather than as an end in itself.
Where it sits against other phono stages AEA carries
It helps to place the EVO 100 V2 among the phono preamplifiers on our floor, because they represent genuinely different philosophies. The Parasound JC3+ and its silver limited sibling, the Parasound JC3+ Silver, are solid state designs known for quiet backgrounds and grip. The Luxman E-250 is a solid state stage with Luxman's characteristically refined, slightly warm voice. The MoFi MasterPhono offers extensive loading and gain flexibility for the tweaker who wants to dial in every cartridge parameter. The TEAC PE-505 is a fully balanced solid state design for listeners building around balanced connections.
The EVO 100 V2 is the one true all tube, tube rectified choice in that group. If you already know you want tubes in your phono stage, not just a tube somewhere in the path but a genuinely tube driven circuit with a tube power supply, this is the unit that speaks that language. The others are excellent in their own idioms, but they are chasing different sonic goals.
Who it is for
This phono stage is for the listener who has decided the analog front end is where they want to invest, and who wants that front end to sound organic and dimensional rather than sharp and analytical. It suits the person running a good turntable and a cartridge they care about, whether that is a high output moving magnet or a low output moving coil, since the EVO 100 V2 is genuinely built to serve both.
It is a natural fit inside an existing PrimaLuna system. If you already run PrimaLuna EVO electronics, adding this phono stage keeps the tube character consistent from the cartridge all the way to the speakers, which is a coherent and satisfying way to build. It also plays beautifully as the tube heart of an otherwise solid state system, warming up and humanizing a chain that might otherwise lean lean.
System, speakers, and room
Because the EVO 100 V2 is voiced toward richness and body, it pairs especially well with speakers and rooms that could use a little warmth and dimensionality. Detailed, revealing loudspeakers benefit from its tonal generosity. In a bright or lively room, that tube ease helps take the hard edge off. In a warm, damped room, you still get the harmonic completeness without it turning muddy, because the tube stabilized supply keeps things controlled.
It has one stereo RCA input and one stereo RCA output, so it is designed as a dedicated, focused phono stage rather than a switching hub. Plan on running your turntable into that single input and its output into a line level input on your preamplifier or integrated. That simplicity is part of its appeal. Every design decision went into making one signal path sound as good as possible.
Living with a tube phono stage
Owning the EVO 100 V2 means embracing a few realities of tube gear, all of them manageable. Tubes want a warm up period before critical listening, and they are a wear item that you will eventually replace, though phono stage tubes tend to have a long, gentle life because they run at modest signal levels. The upside is that tube rolling is possible, and the point to point construction makes this a component built to be serviced and enjoyed for many years. This is not disposable electronics. It is the kind of piece that stays in a system for a very long time.
