    Default Pioneer cd player

    Hey guys..anyone know anything about this model PD-4350. I can't find info about it on the net. I can get it for next to nothing at my local thrift store..course that may very well be all it's worth...only thing i know is it says 4* oversampling on the front. Anyone know if it'd improve my sound any better than the chepo toshiba player i'm using as a source right now?

    sorry. i don't know anything about it.. back in those days different CD players were released nearly every day. just do a search on Sony CD players.. and you'll get like 1,0000000000000000000000 hits..

    Problem with 4 times oversampling.. is it could skip. 8 times oversampling is the least i'd use. I'd say pass on it.

    That's funny.

    EDIT: I'm not commenting on your CDP Jayman...just the Oversampling statement.

    It would be fine for a garage rig.

    find yourself a used NAD on the cheap... they sound good and used ones don't run much dinero. only problem with the NAD's... is their displays are notorious for going out. I've had to replace way to many to count.

    or you could just keep using your Toshiba

    What does oversampling have to do with skipping?

    Nothing, unless you're banging your head on top of it in a drunken rage.

    I over sampled some Rum last night and now my head hurts. I didn't even have to bang it on the cd player ;) :D .

    Oversampling in the context of the D-A process involves multiplying the sampling frequency by a whole number, typically between 4 and 32, or even higher. For example, in ‘8x oversampling’, CD’s base rate of 4.4.1kHz is raised to 352.8kHz by introducing seven new ‘empty’ samples between the original data samples. These new samples, though, are often not just empty strings of noughts, but based on mathematical models to assist the DAC to work more linearly with the extracted data.

    Oversampling, as well as easing the workload of the anti-aliasing filter, which can now operate more gently at a higher frequency, can also reduce distortion created when those analogue signals are first turned from continuous, analogue waveforms into stepped, digital, stair-like curves. This quantization noise is now spread over a larger band after oversampling, and can even be somewhat shifted out of the audible envelope by the technique of noise-shaping.

    Do you honestly think you could hear the difference between a 4x vs 8x CDP?

    If you want to hear a night and day difference, check out a first generation CDP, Kyocera or Phase Linear vs a modern CDP....that's audible.

    no. i think a 8 X and above will track better than a 4x oversampling is all i'm saying. like many a folks on here, who purchased their first CDP.. the first affordable consumer CDP were mostly 4x oversampling.

    Some of those had some problems reading the discs.... that has largely be solved now.. i don't know of any current CDP that still use 4x oversampling. why? because things have improved.

    That's all i'm saying. I"m sure a 4x oversampling player will read a CD... but if given the choice.. i'd pass on a used player that only had 4x oversampling.

    Not trying to bust on ya DB, but oversampling has nothing whatsoever to do with tracking/error correction. Two completely seperate issues. Tracking/error correction is handled by a circuit known as CIRC, see linky

    http://en.wikipedia.org/wiki/Reed-So...ror_correction

    Now, they do use the term oversampling, but it's completely different in regard to how the data (bits) is used. When you are talking about 4x vs. 8x oversampling it's not refering to error correction and the associated (over) sampling that takes place to replace damaged or dropped bits.
