MA-1500 Monoblock Amplifiers By Phasemation

Experience unmatched Sound Quality with the MA-1500. In the diverse world of audio amplifiers, enthusiasts can explore a variety of semiconductor and tube options. Notably, tube amplifiers, especially those featuring the renowned 300B tube have gained acclaim for their superior sound. Building on the recent success with the MA-2000 monaural power amplifier, which utilizes a 300B tube in a parallel single-ended design, Phasemation proudly introduced the new MA-1500.

Key Features:

– Optimized Driver Circuit: Equipped with a Toshiba 6CG7 driving the Psvane 300B tube. The MA-1500 ensures stable, pure Class A operation, maximizing the 300B’s exceptional sound quality.

– Non-Feedback Design: Utilizing triode tubes (5814A, 6CG7, and 300B) at all stages, this amplifier reproduces dynamic and expressive music with unmatched clarity.

– High-Quality Transformers: Featuring inter-stage and output transformers from LUNDAHL, Sweden, the MA-1500 guarantees optimal sound transmission, supporting both 4 and 8-ohm speakers.

– Independent Power Choke Transformers: Each stage—driver and power—is powered by separate choke transformers to eliminate interference, ensuring clear amplification from delicate to powerful signals.

– Noise Reduction Engineering: Designed for minimal noise, the MA-1500 includes a 5R4G rectifier tube, choke transformers in the rectifier circuits, and DC-powered heaters for the 300B.

Elevate your audio experience with the MA-1500, where cutting-edge design meets exceptional sound fidelity.
