The Heart CD600OSE LE begins life as the Marantz LE. Heart then perform numerous modifications to the Marantz design. They disconnects the entire Marantz designed analog section (although it remains in the chassis) and substitutes a circuit using a pair of dual triode 6922 vacuum tubes. The pair is energized by two transformers, one powers the heaters, the other the anodes. The unit ends up with a total of 5 transformers, three for the power supply and 2 for the audio circuits. The printed circuit board is modified and relocated to reduce interference from the power supply. The headphone jack has been disconnected to reduce the load on the audio section and increase performance. Additional Philips capacitors are installed in the high pass section. Finally, additional damping to the chassis and transport has been added over and above that already installed by Marantz. Cosmetically, the only difference between the Marantz and the Heart unit is the addition of a small tasteful "Tubed by Heart" logo below the CD drawer. The Heart CD6000 OSE LE is a very well built machine, and an excellent performer. A beautiful upgrade from the original Marantz. |
