Pre Amps

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.

Introducing one of the most remarkable musical instruments in the world, the BHK Signature Preamplifier. This exceptionally built vacuum tube preamplifier opens up the music and reveals nuances, life and space not previously heard on your system. It is the perfect interface between your sources and power amplifier.

The new Relentless Preamplifier is the ultimate in preamplifier design. The preamplifier plays a critical role in musical playback; the point in the reproduction stage when the music signal is particularly susceptible to compromise through noise and distortion. The use of three separate chassis in the design of the Relentless Preamplifier—a dedicated audio chassis for each channel separated by a power supply/control section—addresses these challenges and brings other benefits besides.

Many audiophiles believe that the preamplifier is the most important component in a music system. It is often the focus of much of the designer’s attention as there are many aspects of the signal path that need to be managed. The Air Tight ATC-3 is a high quality preamplifier with a great pedigree and remarkable sonics. It utilises a tried and true, well proven design that has been refined over many years so that it is very quiet, very transparent, neutral and ultra-dynamic.

It was 30 years ago when Air Tight introduced their first tube pre-amp, the ATC-1 with the ambitious intention being to reproduce real, dynamic sound. So successful were they in realising their ambition that the ATC-1 became a global reference preamplifier for many years and defined that ideal of Japanese refinement. After many years of further research & development, Air Tight have now released the totally redesigned ATC-5 to continue the tradition and cater for the serious audiophile with a requirement for analogue or digital music sources.

What is it that makes the 1110 preamplifier so special? It is something rare, an overachiever, a unique combination of reference-level performance and compact, convenient design. It is at once familiar in size and shape and yet completely new in aesthetic design detail. Perhaps what makes it so special is that it takes such amazing sight, sound, use, and feel and packs them all into a single chassis. It is the perfect mix of traditional function and cutting-edge technology, earning more than 10 international product awards from media around the world.

It is, after all, a Boulder, and every Boulder is special.
