Ayon Audio CD-5 Top Loading Vacuum Tube Class A CD Player

This is an awesome  Ayon CD-5 unit used just a couple times.

Ayon
CD-5 - Pure Class A



“Reference CD-Player”

The Ayon CD-5 establishes another benchmark in triode vacuum-tube CD-Player
performance by combining a true balanced and single-ended tube output stage
with tube rectified current sources in the power supply. Based on a
zero-feedback, pure tube circuit design, the CD-5 reveals the manifold layers
of music with utmost transparency while projecting a deep and highly focused 3D
soundstage. Its bass is extended and powerful, its midrange pure, liquid and permeated
with natural warmth, while the top is extraordinarily clean and finely
detailed. The CD-5 Reference CD-Player offers an uncompromising quality level
in every aspect.





Features & Design

Full-featured tube Top Loader CD-Player with preamp function

Class-A triode vacuum-tube output stage for single-ended & balanced
operation



Signal Path

We believe that the simplest circuits work best together with the shortest
signal path. That is why our pre-amplifiers to date have used single-ended pure
class-A circuitry. The shorter the signal path is, the less possibility of
sonic degradation from various sources, including the wire itself. Even on the
circuit boards, the copper traces are kept to a very minimum length. The
completely redesigned circuit board provides a more straightforward and direct
approach to the signal paths.



Logical sequenced soft-start power up for extended tube life

Warm up function

0dB negative feedback (of any kind )

Ultra short signal path

Simplest direct circuit path for purest musical sound and high reliability

Low output impedance for driving long runs interconnect to an amplifier, and
any tube or solid state power amp

No solid state devices in the analog tube output (signal path )

Minimal discrete wiring for optimum signal propagation

No followers or buffers in the signal path

No DC servo that degrades the signal

High quality parts throughout

Digital output



Power Supply

The power supplies have been further refined with new components and enhanced
AC line noise filtration. Separate power transformer windings and filters
provide total isolation between the input and output stage which makes this a
pure power source and it is a critical attribute for a 6H30 output stage. We
also use electrolytic capacitors with much larger storage capacity to make up
for the loss in filtering when using resistors in lieu of inductors.

3 separate R-Core / Low noise – insulated power transformer for digital &
analog Bridge tube rectification.



Dual choke – filtered power supply and coupled with special film caps

Innovative power supply provides a high speed energy delivery on transients

Separate and isolated power supplies over each stage of amplification

Regulated DC filament supplies with soft start for 6H30

AC power line filter to avoid noise and hash from entering into the unit.

10 separate voltage regulators



Components

The type of parts used therefore must have a synergistic relationship to the
circuit they are placed in. It is this relationship of which type of part to
use where, that ranks our products apart from the mass.

Selected, premium quality passive components used in all applications

Mechanical Construction

The high grade aluminum chassis impart a richer, more lustrous tonality with a
cleaner back-ground and less hash and grain. All brushed anodized
anti-vibration-resonance and non-magnetic chassis’s are fully hand assembled to
insure the highest level of craftsmanship.
