I own a CD transport that plays "red book" it is a CYRUS XTSE2 [latest spec. ] It is specially designed by the digital design engineers in Cyrus with extremely low jitter. the feed-in isn't a tray but a slot-NOT a car type but one SPECIALLY designed by the team NOT a "bought in " product -very smooth feed.
I also have a dedicated PS that plugs into the transport-can play without it but reproduction of CD is enhanced by adding it.
All in an non-metallic box of die-cast construction.
Many companies sell hi-fi gear and you see in posts here people comparing products but for many that's it.
Not Cyrus they have a continual business policy of sending your Cyrus product into the factory for upgrade [a small portion of the full price item] They use STAR -earthing and their equipment is tuned for NATURAL reproduction with an emphasis
on the CORRECT amount of sibilance.
The owners were originally employees in a 1970s/80s loudspeaker company in the UK who formed the new company.
