CAD-300SEI Vacuum Tube Integrated Amplifier
Tube aficionados have long known that the best possible realism and detail comes when an amplifier is run in SET mode or Single-Ended Triode. This lets one power tube handle both sides of each musical waveform, eliminating some of the most fatiguing distortions. It naturally results in lower output power, but with high-efficiency speakers played at reasonable levels, its ultimate simplicity means the ultimate in musical naturalness.
While only offering 15 watts of pure class-A remote-controlled power, the CAD-300SEI does things that almost no other amplifier today can achieve. Its careful attention to design and construction means that it is extremely quiet, allowing the tiniest musical details to float against a background of dead silence. This will help you perceive more accurate soundstaging and imaging cues and the most realistic harmonic structure of each instrument. You can tell a Steinway from a Bösendorfer piano, a Stradivarius from a Guarneri or Amati violin, or a Fender from a Gibson guitar. You’ll hear inner details of musical groups that you never knew existed. Sometimes the simplest IS the best, and the CAD-300SEI is a testament to that philosophy.
