Swiss Made Wiring
?
Swiss Made Wiring
DiaLogue Premium models use Swiss-made, silver-plated, oxygen-free continuous crystal (OCC) copper with a Teflon dielectric in the critical signal path for superior signal speed and increased clarity.
 
Takman Resistors
?
Takman Resistors
If you bought a lesser amplifier, you would pay hundreds to make this upgrade. Easy to identify through their pink color, these premium resistors from Japan are popular with those who rebuild and upgrade their gear. "Modders" love TAKMAN for their low noise, linearity, and musicality.
 
Mundorf Capacitors
?
Mundorf Capacitors
Made in Germany, Mundorf MCap EVO SilverGold capacitors are used in the critical signal paths and while they are expensive, the PrimaLuna team felt they could not be left out after careful listening comparisons with many different types.
 
AC Offset Killer
?
AC Offset Killer - A PrimaLuna Exclusive
DiaLogue Premium is about goose bumps. The ones you get when music comes out of a background so quiet, you may say to yourself “Just how is this possible?”

PrimaLuna custom-winds our own massive toroidal power transformers that are low in hum and EMI. But we wanted more. Our engineers designed the AC Offset Killer to lower transformer noise to a place no other manufacturer dreams of going, regardless of how bad your electricity is. The result? Sense of space. Texture. The resonance of an acoustic guitar or violin string that seems to trail on forever. The AC Offset Killer will amaze you.
 
SuperQuiet Inputs
?
SuperQuiet Inputs
Input selector switches mounted on the front panel requires long wires to run from the switch in the front to the rear RCA jacks, and they invite stray noise like RF and EMI. Additionally, audio quality degrades as the switch gets dirty and worn and they present crosstalk between the inputs. This crosstalk causes noise which obscures micro details in the music.
PrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. The signal path legnth is almost non-existent, so there are no long wires to pick up noise.
Dual Mono Topology
Vacuum Tube Rectified
?
Vacuum Tube Rectified - Dual Mono Design
In the world of preamps, experts agree that tube rectification offers the most natural, textured, vibrant presentation. That's why you find it in the best, top of the line models. Finding a preamp using one rectifier tube is sweet. But PrimaLuna uses two 5AR4 rectifier tubes in their dual-mono design. All PrimaLuna preamps are actually two preamps in one chassis. The result is obvious. Better imaging...like no other. That's where the weight comes from. And weight costs money because it means more and (in our case) better parts.
Point-to-Point Wiring
?
Point to Point Wiring
You spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?
PrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.
Remote Control
?
Remote Control
DiaLogue Premium models feature a full function remote control. ProLogue Premium features a slim remote.
Full Remote Slim Remote
Dual Toroidal Power Transformers
?
Custom Potted Toroidal Power Transformers
Unlike standard EI transformers, toroidal transformers don’t radiate a magnetic field, which can is easily detected in preamp circuits as low-level "hash". Although expensive to manufacture, PrimaLuna power transformers are built huge and rated for 200% of their duty cycle. PrimaLuna transformers are also potted and enclosed to protect the windings from moisture and deterioration forever.
ALPS Blue Velvet Potentiometer
?
Japanese ALPS Blue Velvet Potentiometer
The ALPS Blue Velvet motorized volume control tracks better so a defined stereo image is established and doesn't collapse as you raise and lower volume. And it will stay quiet, adhering to PrimaLuna's guiding principle of "Built to last a lifetime". This part alone costs ten times more than a simple "chip" that we could have used.

Additionally, audio quality degrades as the switch gets dirty and worn and they present crosstalk between the inputs. This crosstalk causes noise which obscures micro details in the music.
PrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays made by Fujitsu in Japan, mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. Relays open and close, so there is no selector switch wiper to get dirty, noisy, or wear out. The signal path is now much shorter. In fact it’s almost non-existent, so there are no long wires to pick up noise.
