'Signature
Edition' of the
SWL 9.0SE adds new upgraded
tube-rectified (5AR4) internal
power supply. The new supply
results in significant sonic
improvements over the standard
SWL 9.0SE. Soundstage is
broader, tonality more organic
and overall musicality greatly
improved.
In keeping with the ModWright tradition of exceptional value, performance and service, the SWL 9.0SE represents a benchmark for high-performance tube linestage preamplifiers. Power Supply: Choke input current regulation, DC heaters, discrete B+ voltage regulation. Gain Stage: Fixed battery bias, Mu* type gain/buffer stage. Power Sequence: Mute-on delay turn-on sequence with soft-start B+ supply. Volume Control: Remote Control Alps motorized volume potentiometer. Design Philosophy: The SWL 9.0SE is designed to offer the Audiophile, World-Class Performance at a Real-World price. The unit is voiced to offer a full, fast and accurate recreation of the entire frequency range. Bass is deep, tight and authoritative and high frequencies sparkle. The tonal balanced is designed to be accurate and detailed without edge or glare. The liquidity and holographic imaging of tubes is present, without the soft or syrupy sound often attributed to tube designs. Use of the very linear 5687 tube and pure Class A circuitry allow for low distortion and exceptionally low noise. Top quality parts are used throughout, including FRED and Schottky diodes, metal film Vishay resistors, ceramic tube sockets and hiqh-quality film caps in signal path applications insure exceptional performance. *The Mu stage circuit type used in the design is credited to Alan Kimmel. Alan was consulted during the design process. |
