Know before you buy
Yes. The Rockwell is designed as a versatile SET amplifier that can power speakers at 5.2 watts RMS while offering multiple output impedance settings (up to 300 Ohms) to accommodate a wide range of headphones.
The 6B4G tube is known for a seductive, holographic soundstage and exceptional mid-range clarity. It is particularly well-suited for acoustic and vocal-heavy music, offering a warm, natural presentation characteristic of Direct Heated Triode designs.
By utilizing a zero feedback design, the Rockwell avoids the phase shifts and timing errors often introduced by feedback loops. This results in a more organic, transparent sound that prioritizes tonal accuracy and spatial depth.
Maintenance is relatively straightforward and affordable. Because the amplifier uses accessible 6B4G tubes, finding NOS (New Old Stock) replacements is manageable, with many options available for under $300.
The Rockwell provides specific output taps for 8, 16, 32, 100, and 300 Ohms. You should select the impedance setting that most closely matches your headphone's rated impedance to ensure optimal power delivery and frequency response.
