A tube power amplifier drives your speakers from a vacuum-tube output stage, trading the raw damping factor of solid-state for the harmonic bloom, midrange presence, and natural decay that valve designs are prized for. Paired with a capable preamplifier, a tube power amp is the heart of a separates system, and monoblock versions take it further by giving each channel its own chassis and power supply. This collection holds all-tube stereo amplifiers and monoblocks from the specialist valve makers we carry. Most are built by hand and designed to be retubed and enjoyed for years.
Current highlights include Rogue Audio's Atlas Magnum III at 100 watts from KT120 tubes with a switchable triode mode, the 180-watt M-180 monoblocks, and the flagship M-250 Ultra monoblocks on KT88 tubes.
