Product details
Product: The Grail SB
Type: Balanced phono preamplifier
Origin: Europe
Use: High-end analog vinyl playback
Included: External power transformer, standard mains power supply
Product description
The Grail SB was created with a singular goal: to reproduce vinyl in the most musical and natural way, free of technical coloration. RIAA correction is achieved using only coils—completely eliminating capacitors from the signal path—for an open and lifelike sound. The circuit boards are made from a specialized material with gold-plated traces, mounted on a vibration-free platform, and supported by wooden damping feet to prevent mechanical energy buildup.
The MC input automatically adjusts to nearly any low-output cartridge—no need to change resistors or settings. Just plug in and play, even at the highest level. For added flexibility, the unit features three inputs (two MC and one MM or high-output MC), selectable gain settings, and an external shielded power supply for maximum noise isolation.
The result? A transparent, detailed, and fluid soundstage with a breathtakingly natural sense of space. A dream companion for any premium turntable and cartridge.
