In the world of preamps, experts agree that tube rectification is the gold standard. It’s quieter than solid state rectification, dropping the noise floor. And it offers the most natural, textured, and vibrant presentation because the circuit is now pure tube. But because it is expensive to implement, you’ll only find it in the top of the line models typically costing $10,000 or more. Finding a preamp using one rectifier tube is sweet. PrimaLuna goes even further using two 5AR4 rectifier tubes in a dual-mono design to present your music with a three-dimensionality that will give you goosebumps.
The DiaLogue Premium uses three 12AU7 tubes per channel. The result is even lower distortion and increased bandwidth over ProLogue. The change in dynamic range is stunning! Distortion levels in the first stage have dropped by a factor of five at low levels, and at least 20 at higher levels, above one volt. The four 12AU7’s on the outside are driver tubes. By using four instead of two, we can swing more voltage. The two tubes in the center are the input tubes, and that’s where you want to have fun later if you wish by experimenting with different tube brands.
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.
