Cambridge – Alva Duo MM/MC Phono Preamplifier

Hear Detail, Warmth, Clarity, and Naturalism from Your Vinyl LPs: Super-Value Cambridge Audio Duo MM/MC Phono Preamplifier Also Includes Headphone Amplifier with Volume Control

Anchored by a cutting-edge switch-mode power supply for quick responsiveness, excellent precision, high output, and low-noise operation, Cambridge Audio’s Duo MM/MC phono preamplifier pushes the boundaries on the analog performance you can get at a very modest price point. Compatible with both MM and MC phono cartridges, Duo touts surface-mount technology for the PCB board – resulting in cost-belying accuracy, black backgrounds, and shorter signal paths. Multi-parallel capacitors that yield terrific RIAA accuracy (0.3dB up to 50kHz) and a high-quality headphone amplifier with volume control also come standard. When you play LPs through Duo, you’ll notice the detail and textures, sense the warmth and naturalism, and see the defined images for which analog is renowned. Ultra-compact dimensions (1.9 x 8.5 x 6.2 inches) and steel-and-aluminum construction also mean Duo fits practically anywhere, offers great stability, and looks classy in any space. Time to get those records spinning. 100% Music Direct Guaranteed.

“Simply put: The Duo was a more than pleasant surprise, producing a generously sweet sonic picture that was well-extended from top to bottom, midrange-neutral and that honestly presented all of the acoustic instruments—all in front of a commendably quiet backdrop.”
—Michael Fremer, Analog Planet

Switch-Mode Power Supply and Surface-Mount Technology Advantages
Switch-mode power supplies and surface-mount technology allow a compact overall design with short signal paths. This guarantees a faster response, greater precision and, lower background noise levels free from the hum and noise that can badly corrupt vinyl’s delicate low-level signals. By specifying switch-mode power supplies, Cambridge Audio employed smaller transformers while maintaining or improving power-output levels. Switch-mode power supplies and software control also allow for improved energy efficiency. Duo automatically switches to standby if unused for 20 minutes.
