Vacuum Tube Reference CD Player (1991)
The Carver SD/A-490t features two 6DJ8 vacuum tubes in the final output stage.
They achieve very low static and transient distortion while providing extremely high dynamic headroom.
This simple but elegant output stage results in unparalleled transparency; because the tubes are run at less than 25% of their maximum capacity, they are not susceptible to ageing effects and should last the lifetime of the SD/A-490t without replacement.
You have chosen a first-quality CD player with triple-beam laser scanning, full remote control including volume control, random play and a Bitstream Conversion Linear Single Bit D/A Converter which represents the latest in digital to analogue translation technologies.
For convenience in making CD-to-tape copies, the SD/A-490t has a variable-length fade feature, an Edit/Time Fade control and the ability to split your selected program into A and B sides.
These features can help you make better than ever tapes which are tailored to the CD's length (and vice versa).
In addition, a version of our Digital Time Lens circuit called Soft EQ sets the SD/A-490t apart from other CD Players - Soft EQ is an extremely sophisticated circuit which prevents the loss of sonic front-to-back depth imaging, as well as the excessive brightness sometimes associated with compact disc recordings.
