Pioneer of Japan has for many decades been considered a serious player in the audio market, mostly in the commercial sector, but at one time, above it as well. To this day, I've never heard anyone challenge this company's reputation for building reliable products, if not always the best in their class.Not too long ago, Pioneer introduced what they called "Legato Linear".To the best of my understanding, this is in fact a variation on the theme or requantization, whereby a notionally 16-bit signal is by some form of interpolation turned into a virtual 20-bit signal. The idea behind this is to widen the frequency response, elevating it from the standard 20...22 kHz to twice that; and indeed, Pioneer quotes a 40 kHz frequency response for this player.The main benefits are supposed to be greatly decreased phase shifts and freedom from compression, especially in the critical treble range, a notoriously weak spot of most single bit systems.Well, model PD-S 507 has that technology, despite its truly modest price tag. And more - it also uses what Pioneer calls a "Stable Platter" system.This translates into what is very alike to a classic turntable, upon which you place the CD, but upside down, with the program side up, not down as in most cases. The disk rests on a center plastic piece, itself mounted on a real, genuine platter.Before you raise your hopes too high too soon, let me add that this platter is merely a gadget - it's too light to be taken seriously, in addition to which it is not too finely made and appears to be wobbling a little.For you vinyl freaks out there, another letdown - no disc clamp, as for example in Electrocompaniet's and YBA units (yes, I KNOW they cost a helluva lot more, just noting!).The fascia is plastic and rather tidy, with what I would call a very logical layout of command buttons.Their action is positive, just about right, not too hard, not too soft, and better than most in this price class. To your right, there's a headphones 6.3 mm jack with its own dedicated volume control, a good move, much better than having to mute the overall output for the sake of headphones.Speaking of output volume, it can be adjusted only via the supplied remote control, but as always, try not to fiddle with it, most CD players sound best at volume full on.
The backside is also very tidy and uncluttered, with only the bare minimum. Output RCA jacks are standard commercial fare, and are not gold plated - a pity. The mains lead is captive, so any changes will involve opening the case and doing some soldering - not recommended for the faint of heart. Also, no coaxial S/PDIF output, optical only; to my mind, this is a drawback.
The insides are very tidy, as we have come to expect from Pioneer. Interestingly enough, they use Nichicon capacitors in most places, two 4,700uF/16V types dominating the show. However, most others are from the same source. Don't expect them to be of the High End type, no MUSE types, just the usual FG series.
The drive appears to be solidly made and looks good for many hours of use. The electronics are tidy and are placed on both sides of the printed circuit board. On the top side, there's an NJR4558D dual op amp in what I think is the low pass filter section, and a Mitsubishi 5218 op amp in what I think is the output section proper - I keep saying "I think" as I didn't have a circuit diagram available, so I'm just guessing from the overall layout and surrounding components.
In any case, tweakers could have a field day with this unit. They could experiment with different op amps, like OP275, OPA2143, AD826 and others, and they could enjoy reworking the power supply, as it uses discrete diodes rather than solid bridge rectifiers. Not to mention exchanging the capacitors for something really wild
