Ortofon ST-7 pris 4450,-

Compact and stylish, the ST-7 has a solid housing supported by four rubber feet, which helps to reduce unwanted vibrations in the unit.

High quality internal wires together with high quality gold plated terminals provide the optimum signal transmission. The sandwich winding structure, used in the ST-7, significantly improves the high frequency response and provides a very clear and open sound over the whole frequency range.

Additionally, the dual-mono design, including the individual shielding of the two channels, improves the imaging of the transformer and

reduces the influence of environmental noise.

Ortofon Verto

The Ortofon Verto reserved for the discerning audiophiles and music lovers. The Verto combines the fine components along with world-class engineering, for unparalleled sound reproduction.

Starting with high quality Lundahl™ transformers, surrounded by a specialized mu-metal shielding, listeners can be assured that every detail in a complex array of notes is reproduced with utter purity, with freedom from internal and external sources of interference. These two items combined make the Verto transformer one of the quietest, most revealing transformers.

Featuring dual mono design, the Verto provides discrete circuitry for each channel, resulting in the elimination of crosstalk and possible distortions. This results in cleaner, clearer reproduction with substantially increased stereo imaging. Regardless of the composition being played, the Verto’s expansive stereo separation provides lifelike realism, and accurate tonal balance devoid of coloration.

To further minimize signal degradation and maximize signal flow, the Verto has been engineered using high quality industrial grade PCB. Additionally, gold plated RCA jacks with Teflon insulation provide optimal conductivity for use with high quality interconnects. Internally, the unit is assembled with an absolute bare minimum of internal wiring, preserving absolute signal integrity.

Ortofon ST-80 SE pris 12300,-

The ST-80 Special Edition Moving coil transformer delivers a detailed reproduction with a touch of warmth accompanied by a full bodied sound quality. Compared with existing models, ST-80 SE has a larger bobbin, more layers in the permalloy core and more coil windings.

The transformer is magnetically shielded in a permalloy case, which in turn is inserted into a robust 10mm thick aluminum cylinder bored out of a solid aluminum block. Together with the heavy metal case the transformer effectively isolates against environmental noise.

The stability of the transformer is superb thanks to its substantial weight of 1.5 kg, ensuring it stays in place even when cables are attached.

The ST-80 SE is built as a pure dual mono model, which ensures maximum channel separation. Internal point-to-point wiring is made by Teflon insulated, solid-core pure OFC copper-wire plated with gold. Together with high quality gold plated RCA jacks with Teflon insulation that ensures the optimum signal transmission and integrity.

The ST-80 SE will be a perfect match to mosthigh quality MC cartridges, such as the Cadenza series, Xpression, MC Anna, MC A95, the historical MC A90 and MC Windfeld, as well as the SPU cartridges.

Shelter 411 Type II
Specification:
Input impedance: less than 15 ohm (tolerance 25 ohm)
Step-up ratio: 32dB
Output impedance: 47K to 50K ohms
Dimensions: 142W x 66H x 106D (mm)
Weight: about 1Kg
Shelter Model 411 Type II pris 9375,-
Shelter model 411

The Model 411 II is mono-functional stereo MC transformer to match with MC cartridges with internal impedance (DCR) of less than 15 ohm. The impedance tolerance is 25 ohms. The transformer is a toroidal design that applies the toroidal winding to 0.05mm thickness of supermalloy, layered ring-core. The core volume has an external diameter of 25mm, internal diameter of 16mm and height of 10mm. The termination of the wire is directly connected to in/out terminal. Therefore, the high efficiency of toroidal transformer realizes extremely low loss structure. It delivers the signal from the cartridge without coloration to the phono- terminal directly. Model 411II is a modified version of Model 411 and it has 32dB of step-up ratio of approximately 40 times.
