About the SP2
The Morrow Audio SP-2 Reference Preamplifier is a high-end audio component designed to deliver exceptional sound quality with a natural and extended frequency response. It features a robust design aimed at conveying a considerable amount of musical information, making it suitable for demanding audiophile systems. The preamplifier includes remote-controllable volume and supports multiple output options such as RCA and XLR. It is known for its full-bodied sound and large soundstage, although it may require careful tube selection ('tube rolling') to minimize noise and optimize performance. Early models had some reliability concerns, but these may have been addressed in later versions. The SP-2 Reference is considered one of the finest full preamplifiers available, with a sonic character similar to its predecessor, the Luminescence model, but with more advanced features and build quality. It is recommended to audition this preamplifier before purchase due to its unique sound signature.
