* Mini disc deck to be used in conjunction with an amplifier or other components such as a CD player or DAT deck.
* Fully functional 59 button infer-red remote, including buttons to allow for easy recording, playing, power on/off and eject, with batteries included.
* Unit has a digital display for displaying information about tracks.
* Unit also has a headphone socket, with a separate headphone volume switch.
* Deck can be used to records and edit tracks with loads of hi-tech features. Record level, timer, add track names, rearrange tracks, cut portions of tracks etc.

Features: Essentially the same as an MDS-JE500 (circuit board, A/D/A chip, ATRAC chip, main ASIC, user manual, feet, all identical). Some units made in Malaysia. European/Japanese unit (see below) adds A-B erase. TOC cloning not possible (machine ejects disc when power applied).

Components: MD mechanism type: MDM-3A/3B, Optical pickup type: KMS-260A/J1N

The ATRAC version used is Sony 4.0. High quality 20 bit A/D Conversion is used with a good DAC. The unit has a very useful monitor feature whereby the DAC can be used independently by the analogue input or either of the digital inputs between 32 and 48 Khz sampling rate. There is a timer and a good quality headphone socket with independent volume control on the unit.

Sony MDS-JE510 (Review by What Hi-Fi)

And that problem is the latest recorder from the inventors of MiniDisc. If this machine doesn't have everything you want, you don't want a MiniDisc recorder.

The Sony uses a new version of the ATRAC system, and also comes with an electrical input. This matches the digital output on most high-quality CD players and sounds much better than the optical feed. Should your player only have an optical output, there's an input for that, too, plus analogue line in/out sockets and an optical digital output, to feed, for example, an external DAC. Facilities and features here are much the same as the Denon's, although the Sony's jog/shuttle dial is much slicker in operation than its rival's thanks to a 'push to enter' facility, which makes editing functions a doddle.

Other goodies here include a 'music synch' system allowing the recorder to start as soon as an input is detected, and 'time machine recording'. This enables you to start up to six seconds after the start of something you want to copy without missing the start: if you record off of the radio a lot, you'll wonder how you managed without it! Add in a remote handset with keys to speed up entry of titles and control track up/down and pause on a Sony CD player, and you've a well-thought-through machine at a very sensible price.

And that's especially true given the Sony's performance. The latest version of ATRAC is extremely good, as is the single-bit DAC used here, and when you record form an analogue source the analogue-to-digital conversion isn't too shabby, either. Digital copies from high quality CD players are all but indistinguishable from the original, and if you're feeding the recorder form a sub-300 Pound Sony player we'd be willing to bet they'll sound identical.

The bass here is powerful and well defined, giving music a firm foundation. Music as diverse as the Michael Jackson dance disc and the Haydn ortortio failed to catch the Sony out, while even close-up jazz with subterranean bass lost little of its impact. Midband and treble projection is similarly impressive - compared with the sound of a top-notch CD player the Sony sounds a shade lacking in ambience, but the nuances missed are very subtle.

Rock and pop is handled with suitable swagger by this machine, the perky pop of Supergrass still zapping from the speakers and all the raw energy of the remastered Hendrix albums captured to thrilling effect. Even copies of vibrant radio broadcasts sound fresh and involving. Just keep an eye on the levels when recording from analogue sources, and the Sony's a breeze to use. Home recording value for money doesn't get any better than this. True, Sony's amazing MDS-JA3ES may just edge it for ultimate sound quality, but then the '510 is 400 Pounds less expensive.
