KT90 Output Tubes
Rogue Audio has developed a series of "Magnum" versions of their Titan series. These Magnum versions feature significant parts upgrades that improve performance in the Atlas, Metis or Cronus in a number of important ways. Increased transparency, greater dynamics, improved bass and high frequency response, and a smoother and more refined presentation are all part of the Magnum upgrade. The extensive power supply mods permit the use of the KT90 power tube which increases the rated output power of the Atlas and Cronus to 90 Watts/Channel. Some of these parts improvements include precision resistors and capacitors, better tubes, gold tube sockets, improved binding posts, and audiophile-grade output wiring.
The Magnum package consist of the following modifications:
Atlas and Cronus Magnum:
- Larger power supply
- Power supply mods
- Polypropylene bypass capacitors
- Precision Dale-Vishay resistors in critical spots
- Upgraded binding posts
- Gold tube sockets
- Upgraded small signal tubes
- KT90 output tubes
- Magnum logo on faceplate
