Boulder 1151 monoblock power amplifier
My first opportunity for an in-home audition came in 2021, when I reviewed the 866 stereo integrated amplifier ($17,500 with DAC, $16,000 without). But that entry-level (by Boulder standards) product, which Senior Engineer Jameson Ludlam said was released to build brand awareness and expand the company's reach by offering "a more accessible product that provides the features we think many people are looking for with the performance they have come to expect from Boulder," only provided a peek at the excellence I expected Boulder to achieve.
So when a last-minute review cancellation opened space to review the just-released Boulder 1151 mono power amplifier ($47,000/pair), I thought, "At last!"

Familiar faces, new form.
Before me stood a pair of stand-mounted Dynaudio Confidence 20 active loudspeakers, complete with DSP ($24,000/pair). Larger, higher-quality cousins to the Dynaudio Focus 10 active loudspeakers I reviewed a little over two years ago, the Confidence 20s sounded notably more refined and more convincing. That tracks: Each driver is powered by its own dedicated amplifier. While both models share the same DSP room correction protocol, nearly everything else is an upgrade.
