I wonder if anyone has had an opportunity to listen to, and evaluate, the
following relatively comparatively priced CD players which all incorporate
tube output stages:-

Jolida JD-100A

Audio Aero Prima

Unico CD

Audio Note 3.1x

The Jolida 100A is also available with quite a number of mods through the
"Parts Connexion" and through "Underwood HiFi" which are apparently "factory
approved" since the original warranty is maintained. If anyone could
comment about these mods I would be very grateful.
