Cary Audio CAD 300SEI Tube Integrated Amplifier
The Cary Audio CAD 300SEI is a 2 x 15W single-ended Class A integrated tube amplifier.
The best possible realism and detail comes when a tube 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 results in lower output power, naturally, but with high-efficiency speakers played at reasonable levels, its ultimate simplicity means the ultimate in musical naturalness.
With careful attention to design and construction, the CAD 300 SEI is extremely quiet, allowing the tiniest musical details to float against a background of dead silence. This will help you perceive more accurate sound staging and imaging cues, as well as the most realistic harmonic structure of each instrument. You can tell a Steinway from a B√∂sendorfer 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 were there. Sometimes the simplest IS the best, and the CAD-300SEI is a testament to that philosophy.
