Just out of curiousity but why whould anyone put tubes in a CD player? Mordante-below are some comments from the Modwright website that Dan makes about his top modded Sony 5400. WHY TUBES? WHAT ABOUT MAINTENANCE? WHY THE 6SN7?
Vacuum tubes are best for amplifying VOLTAGE and SS devices are best for amplifying CURRENT. In a line-level circuit such as this -opposed to an amplifier, tubes require virtually no maintenance.
We chose the 6SN7 for its sound and general popularity among people who love tubes. It ended up being the tube of choice for our Transporter mod, of which we sold hundreds of units!
The tubes are purposely driven VERY conservatively to give 10,000-12,000 hours + of tube life. The circuit is fully auto-bias, therefore no maintenance required. We chose tube rectification simply BECAUSE IT SOUNDS BETTER! |
