PS Audio BHK 250 hybrid power amplifier

Tubed power amplifiers
PS Audio BHK 250

Bascom King and PS Audio’s stated goal when designing the BHK 250 (and its brothers the BHK 300 Mono’s) was to create one of the top five amplifiers in the world and to spare no expense while doing it. Yet they also strove to make them much more affordable than the statement amps found throughout high-end audio. On the PS Audio website page for the BHK 250 and 300 amps under the “Want more product details” tab are nearly an hour and a half of video featuring Paul, Arnie, and – of course – Bascom describing in detail their goals and aspirations for the project. This extraordinary level of manufacturer transparency gives the prospective owner both a high level of understanding and confidence in the product they are purchasing. Bascom, Paul, and Arnie’s combined 150 years of audio excellence has led to a design of classic physical beauty and sonic excellence that easily achieves the goal of competing with über-level amplifiers, but at a fraction of the retail price. As audiophiles, we sometimes fall into the ‘price equals performance’ trap. We fear being the emperor with no clothes when our friends ask how much we paid and it was, gasp! LESS than what flagship gear is supposed to cost. Naturally it must not be that good. This amp is that that rare Holy Grail whose sensible price belies its astounding performance. Hand built in America, it may well be your final amplifier purchase.

Enthusiastically recommended!
