Introduction

Thank you for choosing the Stello CDA500 from April Music.
This superb CD player is also a USB DAC, enabling playback of
computer audio files with up to 96kHz/24bits through
high-quality audio systems. The CDA500 incorporates
state-of-the-art engineering and extreme musicality in a
compact form factor. For music lovers and audio enthusiasts
alike, the CDA500 offers the utmost in sonic reproduction and
quality of construction.

Perfect for music of all genres, the CDA500 features a
top-loading transport mechanism for maximum stability. This
design eliminates the need for a drawer and drawer-loading
mechanism, problematic with players from other makers. The
CDA500 features custom-designed signal-processing and
transmission circuits that emphasize the overall musicality of
the source recording.

April Music delivers the opposite of the cold, antiseptic digital
sound so often encountered with equipment built to rigorous
engineering specifications but lacking the necessary soulfulness
of real musicianship. For us, music comes first.

Downloads are everywhere, but the compact disc is also here
to stay. The Stello CDA500 accommodates both formats with
ease. A superb CD player, the CDA500 features a top-loading
mechanism for trouble-free operation. Electronic highlights
include upsampling to 192 kHz / 24 bits, and compatibility with
both "Red Book" standard CDs and CD-Rs. With a full bank of
analog and digital inputs and outputs, the CDA500 will fit into
any kind of home entertainment system, be it old-school
analog or cutting-edge digital.

The CDA500 is also a bridge to the world of computer audio.
USB connectivity means the CDA500 can communicate directly
with your personal computer, elevating your archived audio
files to CD quality. The computer is a fantastic tool and
ultra-convenient portable library, but it lacks refinement as an
audio playback device. You will be amazed at how good
computer audio can sound when processed through the
CDA500's state-of-the-art Digital-to-Analog converter.
