Those who haven’t heard Rotel’s RCD-1570 might believe that there’s nothing new in CD players. Those who have heard it tell an entirely different story. Since 1982, when the CD was introduced, Rotel has been refining technology and evolving circuitry to bring you extraordinary sound. The RCD-1570, the outstanding CD player in Rotel‘s 15 series, focuses careful refinements to reveal even the most subtle nuances buried in a CD’s pit spiral.
One of the RCD-1570’s most important features is the Wolfson WM8740 digital filter/stereo digital-to analogue converter. Originally developed for high resolution sources, it is the product of extensive research and real world testing and processes digital signals up to 24-bits in length at sampling rates from 8 kHz to 196 kHz.
While word lengths and sampling speed may seem excessive for CDs delivering data at far lower rates, this high speed facility adds reserve capability to ensure proper reproduction under all circumstances. As the most crucial link between a CD’s digital data and the analogue world in which we listen, this converter boasts significant attributes in addition to its superb high resolution capabilities. Another advance is the RCD-1570’s slot-loading disc transport. In addition to mechanical simplicity and improved reliability, this design isolates the CD itself from potentially destructive vibration modes that may affect musical definition. And from a purely aesthetic viewpoint, it adds elegance by simplifying the front panel’s appearance.
The post-converter analogue circuitry benefits from Rotel‘s decades-long experiences in crafting the finest sounding pathway from the D/A’s internal output to single and balanced rear panel connectors that bridge the gap between the RCD-1570 and down-stream components. All circuit components – resistors, capacitors, inductors – are chosen only after their positive contribution to sound quality were quantified and verified qualitatively by extensive listening sessions.
All of these circuits draw on a power supply based on an oversized custom Rotel-designed and precision-manufactured toroidal power transformer that, in turn, feeds precise rectifiers, tight-tolerance voltage regulators, and advanced Slit-Foil low-ESR storage capacitors, all globally-sourced to ensure musically accurate operation under even the most demanding conditions. XRL connectors provide balanced outputs, long recognised for their superior noise-rejecting characteristics while high quality RCA connectors provide an easy pathway to the myriad of components with single-ended inputs.
This is all part of Rotel’s long-proven Balanced Design Concept. It’s yet another way of assuring you that the RCD-1570 evidences a level of attention that will make it part of your reference-level music system for years to come.

The Absolute Sound: "With high-res digital sources, instruments and singers step farther forward from a quieter background, adding to the drama of the listening experience. Apparently, Rotel has not lost its touch with DACs." April, 2014.

Vinyl vs Digital
One of the most commonly asked question is what is better? Vinyl or Digital music.
Short answer is both have their pros and cons.
I will go through the differences are we see them and try to list the pros and cons as comprehensively as we can.
- Delivers analog sound. This is what is refered to as a 'warm' sound. Analog sound is what we hear with our ears. The vibration of the styli (needle) in the groove of the record creates sine waves that is then reproduced by the amplifier and speakers. There is no digital conversion that is an estimate of the music.
- Can last a lifetime.
- Cartidges and styli can usually be upgraded.
- Delivers a wider frequency range including ultrasonic frequencies (above 20 kHz) that have been shown to help the body release endorphines that brings on that 'feel-good' feeling.
- Potentially more accurate sound.
- Can come with booklets with band photos and lyrics.
- Can be easily damaged.
- Large music collections can take up alot of space.
- Not 'toddler friendly' (though they DO make good frisbees)
- Needs more maintenance.
- Not a portable media.
- Large collections in very small space.
- Can be used in multiple devices. (computers, phones, MP3 players, CDs, USB sticks, etc)
- Much less suseptible to physical damage than vinyl.
- Can be organised much more efficiently. (search entire music libraries with a simple click)
- Digital devices can be improved by external Digital to Analog Convertors. (DACs)
- Can be digitally remastered after recording. (Usually done is a studio)
- Easy to make copies of files.
- Can lose entire collections if hard discs fail.
- Doesn't have the 'warmth' that vinyl has.
- Is not an exact copy of the music. Digital music is an estimate that is accomplished with 'sample rates' (the higher the sample rate the closer to the original)
- A lot of digital music is compressed. (lower sound quality)
- Potential compatability issues with different file types on different hardware.
