Unfortunately we are experiencing long production lead times due to moving our manufacturing base to Belgium. Please contact us for more information.
Our 170 stereo power amplifier has been designed to deliver a refined, organic and natural soundstage, without being over analytical. With the 170 we wanted realism, with a sense of ‘being there’, not just for powering our Sibelius loudspeakers but for all makes and models.
The Pearl Acoustics 170 single ended power amplifier, is a totally new ground-up bespoke design, the result of working together with some of the best minds in the business. The amplifier features an extremely short signal path, bespoke, custom designed output transformers and power supply circuitry. Our design concept has been focused on sustainability by incorporating product longevity into every aspect of its design, without limiting its clean, engaging and holographic sound performance. Musical finesse with very fine details and superb dynamics have been combined into a piece of equipment that is designed to last ‘forever’.
