The Onkyo TX-5000 is a vintage stereo receiver known for its robust performance and excellent tuning capabilities. Users report exceptional sensitivity and selectivity in its tuner section, making it particularly effective for FM radio. It features an analog dial complemented by a quartz-locked digital readout, allowing for precise tuning. The audio output is characterized by fullness and articulation, delivering quick dynamics and well-balanced sound across the frequency spectrum. In comparisons with models like the Marantz 2226b, 2230, and 2270, as well as modified tube amplifiers, the TX-5000 is noted for its improved bass response and a blend of crispness and tube-like warmth. Its construction quality is highlighted, with high-grade components and a range of functional buttons. However, one notable drawback is its particularly wide design, which may pose a challenge for fitting into some audio setups.
