    Phiền các bác một chút!

    Các bác ai đã dùng cho em biết ý kiến về chất âm của đầu CD Pioneer PD T05 hoặc có thông tin gì khác thì cho em biết.

    Em hay nghe nhạc nhẹ với các giọng hát trầm ấm, nhạc không lời (bao gồm cả các loại đàn dây).

    Cảm ơn các bác

    Bác phuongaudio đã lấy em nó chửa?
    Nếu lấy rồi mới hỏi thì...... còn chưa lấy thì theo thiển ý của em bác không nên lấy em này.
    Có chăng dòng PIONEER thì lấy em PD-T07,
    Em thấy em này hợp lý đấy bác ơi. Thử hỏi chủ nhân em nó xem thế nào.

    Nhân tiện đây cho em hỏi luôn, con Pioneer PD-T02 second hand giá 1,7 triệu có nên lấy không các bác? Em mới tim hiểu về đồ âm thanh nên không thao giá lắm mong các bác chỉ giáo.

    Em tìm được thông tin của nó đây, Bác tham khảo:

    Pioneer PD-T05
    \ 80,000 (1990 sale)

    The CD prayer which confronts the first generation who adopts turntable system.

    It developed from the disk stabilizer, CD turntable system is adopted.
    By the fact that it makes the structure which installs the pickup and the spindle motor on top of the disk, same as the analog prayer the disk it has become possible from under to support with the turntable whole surface.
    Because of this, moment of inertia of the turntable improves in former approximately 3 times, has become strong in the external vibration and the influence of the sound pressure and the disk etc which has [sori], holding down the unnecessary vibration of the disk with possible.

    The 8fs digital filter and the left and right independent bitstream D/A converter are loaded by the D/A converter.
    This D/A converter is not occurrence of error of the resistor like multiple bit system and the non-linear characteristic strain and zero cross strains which originate in the gap of operational timing in principle. Furthermore by the fact that the high over sampling where 3 next [noizushieipa] are called to the base 192fs is done, influence of [noizushieipa] is held down low.
    In addition, with 1 bit system all operations are controlled with the system clock, jitter of the system clock exerts influence on efficiency. In order to avoid the influence, the same as former multiple bit system low system clock (16.93MHz) with it is operational.
    In addition e.g., we pay attention to also application, we provide the oscillating circuit which becomes independent, vibration-proof anti magnetic processing is administered.

    In order to transmit the music signal purely, we adopt direct construction, by the fact that paralleling to the signal flow, it designs the principal circuit simply & straightly, we actualize the minimization of signal route.
    In addition, digital/it separates servo and the audio baseplate in addition to the center tray design which allots the pickup mechanic on the center, prevents the interference in each circuit. Furthermore the analog circuit baseplate from input to the output terminal you tie at shortest distance, have made left and right symmetrical constitution.
    Because of this invasion and circuit mutual interference of the noise with drawing around the wiring material are removed.

    We adopt the clean laser pickup of the respective company development to the pickup, we have made the power loss of optical system decrease by reducing optical part such as collimator lens. Furthermore aberration inside the optical path is made to decrease, the pickup of the signal where the strain is little is made possible.
    In addition high accuracy being able to actualize precise form it is by adopting the engineering plastic body to the body, the pickup body divides into the element of approximately 1000, does strength analysis.
    Furthermore, we build in the I/V conversion head amplifier to the photo detector, by the fact that it expands in approximately 200mV order, we make the transmission which is strong in disturbance noise possible.

    We adopt the A class operational FET buffer amplifier to the audio circuit, lower output impedance, we have decreased influence such as load of the amplifier which is connected.
    Furthermore fluctuation of the electricity consumption quantity when operating is decreased with A class operation, the waveform transmission which is stabilized is actualized.

    High accuracy the occasion where laser light is received, phase difference causes 4 divided photo detectors, between the preceding signal and the rear line signal, the disorder occurs in the RF signal. In order to improve this, we adopt [akiyuhuokasushisutemu], being able to delay the preceding signal by the delay circuit, we obtain the RF signal whose reading error is little by making coincide with the signal of rear line.

    Starting torque the 65g cm brush less hole motor is loaded in the spindle motor. Furthermore the pole of φ4.5mm coupled with the shaft thickly, you show the rotary efficiency which it stabilizes strongly in load fluctuation.
    In addition being quiet, we employ the silent linear motor servo mechanic whose smooth operation is possible to pickup drive, make fast access possible.

    In order to protect optical mechanism from the external vibration, [ramisatomekabesu] is adopted.
    This the steel sheet 2 superpositions, being something which the moulding is done with the special resin, holds down the improvement of periodic damping quality and the occurrence of the magnetostriction furthermore with administering copper plating.
    In addition, this mechanic base through [koakishiyarusasupenshiyon] which the special rubber and the spring to same axis is converted, has mounted in the mechanic chassis, also the turntable base through [koakishiyarusasupenshiyon] in the same way, it mounts, by the fact that respectively it makes flow and structure, it cuts off the external vibration from the chassis.

    The multilayer structural honeycomb chassis of new development is adopted to the chassis.
    The honeycomb chassis internal loss BMC of high rigidity (Bulk Molding Compound) by largely in the base, being something which superposes the steel sheet and the cushioning material which are superior in the electromagnetic shielding, it decreases the unnecessary vibration with the damping effect which is superior, holds down also the reflection of sound from the floor low and increases.
    Furthermore vibration-proof characteristic and weight balance are taken with with k which installs the 5th insulator in the chassis central part in the insulator, center mechanism is supported.

    The twin power trance which it becomes independent the for digital/servo circuit and to the one for analog circuit is loaded in the power source section.
    Furthermore we adopt bifilar volume to trance for the audio circuit, + side, - power source side is supplied under identical conditions by output impedance and raising the balance of inductance, the transparent impression and low the drive impression in the limits has improved.
    In addition the power circuit has adopted 4 part 11 regulator, servo/digital, servo drive, + of audio, - it becomes independent rectifies 4 parts, removes mutual interference.

    When pushing the operation key just, we load the clean micro-computer which operates, cancel scanning noise.

    The digital/analog logout Change-over Switch is loaded.

    Scanning noise occurrence at the time of display illumination is considered, the display OFF switch is loaded.

    trong loại bình dân thì PD05 và PD06 nghe ổn cực với chi phí vừa phải em đã test kỹ loại này và một số loại khác đắt hơn gần gấp đôi tiền nhưng không qua mặt được em nó nhất là bác nào thích nghe giọng ca sĩ quên sầu luôn nói chung với giá tiền bỏ ra điều em nó mang lại là rất ổn (em đã tets PD05,PD06,TEAC10,SONY30es,và dừng lại với em PD06 theo tiêu chí tiền bỏ ra\âm thanh mang lại.300usd cả điều khiển cho em PD06 đẹp từ trong ra ngoài)còn điều này nữa các bác cứ bế em nó lên thì thấy giá trị của em nó rồi mở bụng xem ruột gan em nó sẽ thấy mê luôn vài dòng cảm nhận kính các bác thêm ý kiến

    Nếu thích Pioneer đời mới thì nên lấy PD-T07.
    Rẻ tiền màu đen thì có:
    PD-2000 cao hơn là 3000 và 5000

    Thân mến

    Nếu đẹp long lanh thì phải > 400 bác ạ. Các đời có đuôi A, S, HS thì còn cao hơn nữa. Em thấy Pioneer tiếng rất cân bằng, các đời mới có độ chi tiết cao...

    Chất âm của T05 tương đối chi tiết mượt mà đáng đầu tư trong tầm tiền. Bác nghe bộ gõ hoạc ghita cung rất hay
