Virgo III is a subtle but significant evolution of our Virgo II line stage preamplifier. The new version introduces a unique, passive implementation of a digital volume control created by our "dream team" of world-renowned audio engineers.

Only the Momentum preamplifier can deliver the sound quality necessary to get the maximum possible performance from the Momentum monoblock and stereo amps.

Like the Momentum amplifiers, the preamplifier uses complementary balanced circuit topology for maximum bandwidth and low noise. Its audio circuitry is fully discrete, with no op amps. Zero-feedback design assures the most musical sound quality. Volume adjustment is made through a resistor ladder governed by an optical controller—the cleanest, most transparent possible method of controlling volume.

The Progression Preamplifier adds new features previously not included in a D’Agostino preamplifier. Most noticeably, the Progression Preamplifier features an optional digital module. The digital module adds coaxial, Toslink, and USB capability to the analog base model. A fully differential DAC handles PCM signals up to 24 bit/384 KHz and DSD signals up to 4xDSD (11.2 MHz). This digital module feeds a discrete, fully complementary and balanced analog signal path from input to output. Negative feedback is not used anywhere in the Progression Preamplifier, nor is it necessary. Open-loop distortion is less than < 0.006% and the open loop bandwidth extends to over 100KHz.

The darTZeel NHB-18NS is the logical partner to the now acclaimed NHB-108 model one power amplifier. In keeping with the very same philosophy, darTZeel uses dedicated circuits reduced to their most basic form. Here again, there is no application of any overall negative feedback. The delicate, small audio signal amplified by the NHB-18NS only passes through 8 silicon junctions from input to output, including the 13dB full discrete gain stage. For the phono stage, we only add 3 junctions, for a maximum additional boost of 60 dB (73 dB in total).

Incredibly compact valve pre-amplifier for analogue line level. Using three ECC88s to create smooth sound. Luxurious design with chrome facia and gold or chrome knobs. Connect up to five analogue line inputs with a tape output.

Engineered on the same core technologies as the studio grade brother, the EAR 912. The EAR 868’s smaller size may mean theres less of it but there’s nothing less to it. It’s still big on performance with circuitry designed by Tim de Paravicini. The 868 utilises the same reliable PCC88s in a configuration of four.

The EAR 912 is a culmination of Tim de Paravicini’s work with professional studios. Specifically designed for playback in studios, inheriting the product a rich feature set in addition to its high grade sound.

he Illusion II is the perfect centerpiece for a world class digital and analog audio system. Added to the normal selection of balanced and single- ended inputs are five digital inputs. The digital module features AES/EBU, coaxial, and optical digital inputs for use with streaming devices or other digital sources.

Circuitry Highlights: the Illusion II preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero feedback, balanced, Krell Current Mode design, the Illusion II shares the same design philosophy as its bigger brother, the flagship Illusion preamplifier. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder - bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting.

DUAL TOROIDAL POWER TRANSFORMERS

Power transformers generate two types of noise, magnetic and acoustic. That's why toroidal power transformers are used in the very best audio products. Compared to standard transformers, toroids radiate about 1/10 the magnetic field that pollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn’t cut corners. All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever. They are massive, resulting in a preamp weighing a substantial 31 pounds.
