Acoustic Plan PhonoMaster
PhonoMaster is an equipment to amplify electrical signals of phonograph pick-ups. These can be moving magnet (MM) or moving coil (MC) systems. The frequency response is equalized for RIAA. With minimalistic circuit design best sound quality is achieved without any compromise. Only one transistor is responsible for amplification of the low MC signals. Overallfeedback, differential amplification and push-pull circuits are not used. Adjustment of the MC imput impedance to the pick-up is superfluous due to the use of a current control circuit. Tubes are only installed where they are able to develop their whole range of advantages: for prevention of natural harmonic spectrum, fusion of neutrality and liveliness as well as the exceptional dynamics. One output transistor guarantees low output impedance to drive long cables without losses. Unregulated switching power supplies avoid any kind of humming and noise. PhonoMaster is equiped with double sided printed circuit boards for tight fixing of ceramic bases and all other components.

RS-28CX from Leben is equipped with the CR type equalizer based on GE 12AT7 authorized by J.A.N. (Joint Army & Navy) standard of US Army, and can reproduce a very high quality and clear sound without adding any NFB. Some of the finest available high-end audio components were selected for the RS28C to keep the deflection of the RIAA curve below +/-0.3%. Of course, the phono equalizer is only one of the strengths of the RS28C. Another notable feature is a very strong output voltage created by the Dual-Triode Tube 6CG7 of General Electric(USA) used for the line stage. Leben further selected the best quality tubes out of these and constructed a powerful SRPP type amplification which can supply power amplifiers with a maximum 80V of clean output signal.

VTL 5.5 Series II Preamp
Since its introduction in 1997, the TL-5.5 has earned a reputation for outstanding performance at an economical price. Now, VTL has significantly upgraded this preamp, using many of the technological innovations derived from the flagship TL-7.5 preamplifier. The result is a modern full-featured preamplifier that outperforms in every way, making it one of the top values of any tube preamplifier in its category. The fundamental qualities that made the original TL-5.5 special—its all-tube design, the optional retrofittable phono stage, and its superb sonic characteristics—are unchanged. What’s new is the application of advanced audio technology sourced from VTL’s TL-7.5 Reference and TL-6.5 Signature preamplifiers. This technology uses a simple circuit topology with low negative feedback and a high current/low impedance output stage in a low-noise microprocessor-based design. Top quality parts, fully balanced operation, and precision-regulated and shielded power supplies yield a full yet neutral sound with high resolution, transparency, speed and powerful dynamics. Much of the engineering prowess inherent in these world-class preamps has been transferred to the new TL5.5. New fully regulated power supplies are similar to those of its bigger siblings and the unit is now fully balanced, for inputs as well as outputs. Similarly, VTL’s latest thinking from our new and acclaimed TP-6.5 Signature phono stage is now applied to the optional MC phono stage, which can be easily retrofitted internally. It offers 68dB of gain and a balanced output, with a JFET/12AU7 high current MC stage (or high-grade stepup transformer), split-pole passive RIAA stage with a dual 12AX7 MM stage for maximum headroom voltage swing. Triple-precision power supply regulation and full gain and load setting with RIAA enhanced and rumble cut functions translate to a clean and quiet yet dynamic sound that brings vinyl to life! VTL has delivered on its goal of bringing advanced engineering and modern functionality to the new TL-5.5 Series II preamplifier. With the same highly intuitive user interface of the renowned TL-7.5 and 6.5, and a full-function remote, the new TL-5.5 is a pleasure to use. A rigid, well-shielded chassis yields quiet operation while bi-directional RS-232 serial interface allows for seamless integration into any audio system. A luxurious cosmetic makeover includes a sleek and visually striking precision-milled faceplate similar to those used on its much more expensive brethren. For a well-priced, high-performance all-tube preamplifier, the TL-5.5 is a truly fine addition to any system.
VTL TL6.5 Series II Signature Preamp
More than seven years after introducing the TL6.5 Signature Preamplifier to wide acclaim, VTL presents a significantly revised version, the TL6.5 Series II. The new model incorporates numerous circuit improvements while retaining the best elements of the TL6.5 platform. The proven strengths of the original system design include a single chassis architecture, a fully balanced differential design, a hybrid circuit that combines tubes in the gain stage for voltage linearity, with a FET buffer for greater current capacity, a high resolution volume control with high overload capability, and precision-regulated power supplies. The highly-regarded user interface of the TL6.5 platform is renowned for its intuitive functionality and ease of use, with full-function remote control, and a fully bi-directional RS-232 control interface for increased compatibility with modern home theater systems. The TL-6.5 Series II incorporates most of the advanced technology found in VTL’s flagship preamplifier, the TL-7.5 Series III, for a dramatically higher level of performance compared to the original design. The new version features an extensively revised power supply based on current-sourced shunt regulator technology that minimizes impact on the audio signal. Far more precise power regulation yields dramatically improved rejection of noise and AC fluctuation. The completely redesigned high current gain stage utilizes newly available FET technology developed for green technologies such as solar panels and electric cars that require a normally-on state. Unlike MOSFETs that need to be biased on, normally-on devices operate more like vacuum tubes in the audio output stage, with simpler circuits that continuously conduct current, resulting in a more tube-like sound. The high-current gain stage is shock-mounted like the TL-7.5, and has been further optimized for linearity, with zero global negative feedback. Also included in the upgrade are re-voiced audiophile grade capacitors and additional bypassing. Enhancements to the Series II result in an overall more tube-like sonic character, with more defined images in the listening space, a higher level of inner detail, and a dramatically improved mid-bass and midrange. The TL6.5 Series II is an exceptional match with any of VTL’s other Signature products.
VTL TP2.5 Series II Phono Preamplifier
The new TP2.5 Series II phono stage represents a tremendous value for those looking to assemble a high resolution analog system at a reasonable cost. Completely redesigned from the earlier version, the TP2.5 is trickled down from our flagship phono stage, the renowned TP6.5. Delivering a large measure of the musicality and resolution of its much more expensive stablemate, the new TP2.5 offers dramatic improvements in speed, delicacy, nuance and drive. Crafted with a similar high quality build and finish as VTL’s more expensive models, the TP2.5 has an elegant silhouette, and the features to match. With an eye toward flexibility and user friendliness, the 2.5 offers user-adjustable cartridge impedance, and two levels of gain, with inputs for both MC and MM cartridges. JFET/tube hybrid circuitry is used for the MC stage, and all-tube circuitry for the MM stage. Enhanced RIAA compensation and a front-panel switchable rumble filter offer even more functionality. The signal path is purposely kept simple and direct, with audiophile-grade components throughout, for ultimate sonic purity. With the new TP2.5 phono stage, we have created an entry to true high-end analog sound. The VTL ‘family’ genes of highly resolved detail, linearity and controlled bass are all there, along with a musicality, depth and spaciousness you won’t find in most phono stages. For the true music lover seeking to capture the special magic that only a fine analog system can provide, the new TP2.5 Series II phono stage is an essential component.
