Local Southern California builder Justin Weber runs a small company, ampsandsound, which produces a fine line of reasonably priced tube amplifiers and high efficiency horn speakers. His $1800 Stereo 15 Special Edition is one of the best sounding affordable tube amps I've ever tried. Utterly silent background levels with superb dynamics and tone. Ultralinear configuration with a pair of low cost EL84 tubes per channel, tube rectified and beautifully finished. Can be custom ordered for either 4/8 or 8/16 ohm speaker connections. Just make sure you mate it up with speakers that can be driven adequately by 15 watts. I used the amp mostly with Tekton or Fritz speakers and the sound was gorgeous in every case.
