Comparison Lenco LS-300 vs Lenco LS-50

The presence of a non-removable pickup in the design of the player.

The pickup (cartridge) is a key part for any turntable; failure of this part renders the entire device unusable. Therefore, non-removable (that is, unsuitable for replacement without disassembly in a workshop) pickups are made mainly in low-cost players, where the manufacturer tries to simplify and, accordingly, reduce the cost of construction. However, even in such models, usually, it is possible to replace the most delicate part of the pickup — the needle.

Model of the pickup (cartridge) supplied with the player. The pickup is one of the most important parts of any vinyl player, the quality of the received sound largely depends on its quality. Knowing the name of the model, you can find detailed data on it and determine how satisfied you are with this particular cartridge.

The signal level at the output of the pickup supplied with the player is, in fact, the power of the signal coming from the pickup to the phono stage. This parameter is necessary, first of all, in cases where the player is planned to be connected to an external phono stage: such equipment must be designed for the corresponding power of the signal coming from the pickup.

The force of pressing the needle on the plate, which the complete pickup (cartridge) is designed for.

This force depends on the rigidity (compliance) of the needle: the greater the clamping force, the harder the cartridge, respectively, the less pliable it is. It is also believed that less pressing force wears out the record less, but it cannot be said that "light" cartridges are definitely better — there are many other nuances. So in fact, information about the pressing force of a complete pickup is needed mainly in case of its replacement. Usually, the pressing force provided by the arm of the turntable is regulated within these limits, so the new cartridge must also be rated for the same values of downforce — otherwise there is a chance that the turntable will not be able to correctly align.

The weight of the pickup (cartridge) supplied with the turntable.

The weight of the cartridge determines the characteristics of balancing the tonearm to set the optimal tracking force. However, pickups in set are usually optimally compatible with the corresponding tonearms, so there are no problems with adjusting the turntable. But when buying a replacement cartridge, you should pay attention to this parameter: it is advisable that the new cartridge does not differ too much in weight from the old one, otherwise the tonearm adjustment range may not be enough for the correct balance.

Shape of the complete tonearm (viewed from on top). Modern players can have both straight and S-shaped or J-shaped tonearms. It is impossible to say unequivocally which one is better: the advantage of the first option is considered to be light weight, the second and third are long length and low resonant frequency, which reduces the likelihood of interference. Therefore, in practice, the choice depends on the specific situation and personal preferences.

The main material used in the construction of a complete tonearm.

— Metal. Usually, in this case we are talking about an aluminium alloy. This is a fairly light and durable material with average characteristics in terms of sound quality: it does not dampen extraneous vibrations as well as carbon fibre, but for entry-level and mid-level turntables this is quite enough, in expensive models you can use other methods of eliminating interference, aluminium is much cheaper.

— Carbon. A high quality material that is lighter in weight and has more advanced anti-resonance properties than the metal described above. The main disadvantage of carbon fibre is its rather high cost.

— Plastic. Plastic has a low cost, but this is perhaps its only key advantage: the performance of this material is quite modest. That is why it is used extremely rarely — mainly in retro-style turntables, where a plastic tonearm is a necessary part in terms of design.

An external power supply is called a power supply unit (PSU) placed outside the player's case; such a unit can be connected to the outlet with a wire or plugged directly into it using its own plug. The point of this arrangement is to minimize possible interference from the power supply electronics by removing it to the maximum distance from the circuits through which the signal passes. Therefore, an external power supply is considered the best option for audiophile class acoustics.

A phono stage is a specially designed preamp used with vinyl record pickups. Initially, the sound on such records was recorded with a distortion of the amplitude-frequency characteristic, namely, with an increase in volume from low frequencies to high ones; this is due to the technical features of the recording process. Accordingly, the phono stage not only amplifies the signal to a level sufficient to supply power to the amplifier, but also corrects the frequency response, “pulling out” the bass and reducing the volume of the high frequencies. And the built-in phono stage allows you to connect the player to the power amplifier directly, without the use of intermediate equipment. However according to the characteristics, the built-in preamplifiers-correctors are inferior to external ones. Therefore, in some models with this function , bypass mode may be provided, which allows you to send a signal bypassing the built-in phono stage to an external, more advanced one. And also there are even vinyl players without a phono stage.
