Lyra Delos MC唱头
While vinyl records played back with an MC cartridge can sound exceptionally good, it is a surprising fact that the design of conventional MCs restricts the sound quality that can be achieved from LPs. An essential factor for proper operation of an MC cartridge is the angle between the magnetic circuit, signal coils and core. Performance is optimal when the angles are all aligned, but any significant difference in the angles will cause the formation of a strong and directional flux that will flow constantly from the magnetic circuit into the signal core. This directional magnetic flux will orient the core toward a specific direction and make it impossible for the core to move with equal ease in all directions, which is necessary for proper cartridge performance. Unfortunately, conventional MC cartridges have been designed so that the angles between magnetic circuit, signal coils and core become aligned only when tracking force is not applied. The result is that during playback, the required tracking force causes the angle between magnetic circuit, signal coils and core to become misaligned. This limits the cartridge’s resolution, tracking ability and dynamic range. The new Lyra Delos is designed to conquer this problem. Compared to conventional cartridges, the Delos has a new body structure with an unusually shallow angle, and this has been paired with a unique asymmetrical damping system. When no tracking force is applied, the shape of the asymmetrical dampers forces the signal coils and core into a more upright angle than the magnetic circuit. However, no tracking force applied means that the cartridge is not operating, and therefore any angular discrepancies between magnetic circuit, signal coils and core will have no effect on performance. When tracking force is applied, however, the force of the stylus pushing on the LP causes the asymmetrical dampers to be deformed into a symmetrical shape, and when this happens the angular discrepancies between magnetic circuit, signal coils and core all disappear. Since tracking force applied means that the cartridge is now operating, it should be clear that the design of the Delos is able to keep the angles between the magnetic circuit, signal coils and core aligned during playback. Keeping the proper angular alignment prevents the formation of any strong and directional flux that could otherwise flow constantly from the magnetic circuit into the signal core, and enables the Delos’ core to move with equal ease in all directions, for optimal performance. The Delos also has a microridge stylus on a boron cantilever for outstanding tracking, a non-parallel solid machined metal body for low resonances, and 6-N high-purity copper coils and nude construction for greater clarity. The result is clearly improved sound quality, particularly resolution, tracking ability, dynamic range, transient impact and immediacy. Feel free to audition the Lyra Delos, and hear how good a New Angle can make your LPs sound.

Tedeska DST201ua唱头
Body:Tonewood, Brass, Bone, Nacre Type:Moving Coil  Air core coil generator (FAQ-Technics-Q2) Wiring:6N Copper Magnet:Samarium cobalt  Cantilever: / Contact pins:Boron / Double-hardened pure Silver Output Volts:0.3 mV ± 2dB 1KHz/5 cm/Sec/45°  Frequency Range:20Hz to 35kHz Channel Sep.:a>27db / 1kHz Impedance:approx. 16 Ohm Weight(S): (S/C)*** approx.12±0.5g Tracking force: 1.8g Compliance:12 x 10-6 cm/dyne at 10 hz Made in Berlin by musician Hyun Lee, the Tedeska DST201UA is a hand-built moving-coil cartridge encased in a hardwood body to which shellac has been applied using a traditional French polish technique. Its copper-wire coils are wound on an air-core former, bathed in the flux lines of a samarium-cobalt magnet; a line-contact stylus is fitted to the business end of its boron cantilever. Specs include an output of 0.3mV and an impedance of 18 ohms: a curious combination, as the latter seems much higher than the former would lead one to expect. Recommended downforce is 2gm. With the Tedeska in his system, MF expressed some disappointment that macrodynamics were less than fully expressed—"I wanted more oomph"—but praised the DST201UA as "a well-balanced, high-performance cartridge that bridges the gap between being too soft and too analytical."
高度风Ortofon MC A Mono唱头
The MC A Mono is a TRUE MONO cartridge for play-back of MONO recordings.  If you play a MONO record with a stereo cartridge you will not achieve the same signal in the two channels due to imperfections such as crosstalk, noise, phase errors, tracking error, antiskating and distortion. This difference between the channels will result in an unstable and partially fuzzy image. A mono switch, to some extent, can improve this. Playing MONO record with a TRUE MONO cartridge will have none of the aforementioned problems, as this cartridge only produces one signal, which afterwards is directed to both channels in the system. This will provide a much more forceful and stable image with a fuller sound. Another significant advantage of using a TRUE MONO cartridge to play MONO records is the absence of response to vertical movement. This means that a TRUE MONO cartridge is essentially impervious to the pinching effect which comes into action when the stylus is pushed vertically upward in very narrow grooves. In addition, the response to dust, dirt and wear will be reduced substantially as the vertical component will not be heard. The final result will be a much more clean and noiseless reproduction of the MONO record. These effects simply cannot be achieved merely by the use of a mono switch.

Miyajima Labs Destiny唱头
Maker: Miyajima-Laboratory Product name: Stereo cartridge -Destiny- Impedance: About 16 ohms (About 0.23mV output) Frequency range (-3dB): 20 Hz to 32 kHz Tracking force: 2.5 g Stylus Shape: nude Line contact diamond stylus Compliance (10Hz): around 9×10-6cm/dyne Appropriate temperature: 20-30 Celsius (most suitable 25 C) 68-86 Fahrenheit (most suitable 77 F) Weight: about 13.3 g Body: African Blackwood Among many experiments, I learned that there is an important relationship between the needle pressure of the cartridge and the weight of the main body. However, it was not a good thing if it was heavy, but we needed ingenuity of material and structure. The completed sound is a balance like an isosceles triangle. The bass is thick and tight. Mid-range is firmly insisted. A treble that has no useless resonance is realistic. Sound separation is the best ever. It is feeling that all the performers are putting their feet on the ground. The sound image is stable, there is spreading and depth and presence. When you finish listening to the LP, you will feel like clapping players unintentionally. Destiny of the stereo cartridge used bamboo cantilever and LC solid diamond stylus. Bamboo cantilever is tapered. It is light and strong by careful processing. Until now, we have weighted the head shell and adjusted the weight with a spacer. However, it seems to be a little different from when we heavy the cartridge body. Low-frequency energy is strong. I would like to listen to drums and bass' s Arco style all the time. Vocals are fresh. There is little sense of distortion, and it reproduces to very small sounds. By making the body heavy, the extra sound generated by the intense movement of the needle point is gone. Since the self weight of the cartridge became heavier, it is necessary to select the arm, but it was able to demonstrate the merit of the cross ring method to the maximum.
