DESCRIPTION
Designed to appeal to discerning audiophiles, the Concept 500 achieves a perfect balance between art and science. It is a loudspeaker that is at once, stylish, contemporary, fine-sounding and astonishingly accurate. It couples low directivity with wide bandwidth, good sensitivity and sensible impedance. This makes the new Concept 500 both room-friendly and an easy load to drive, allowing amplifiers to deliver their best performance.
To create a stereo soundstage which gives as good an impression of width, depth and height as that found in a live performance requires high quality drive units, a well designed crossover and an accurately constructed cabinet. To achieve this, Q Acoustics formed a truly talented team with many years of experience in the design, engineering and manufacture of world-class loudspeakers. A combination that resulted in a state-of-the-art loudspeaker worthy of any high-end system.
FEATURES
- The High-end Concept 500 Floorstanding Speakers adopt advanced, innovative technologies to deliver pure audio excellence and a sensational sound stage.
- The Concept 500 pairs Point-to-Point (P2P™) bracing to deal with low-frequency panel vibrations with Helmholtz Pressure Equalizers (HPE™) to balance out pressure irregularities.
- Three separate layers filled with a non-setting gel, which dampens the cabinet walls and converts higher frequency vibrations into heat for better performance.

DESCRIPTION
Think of the Stellar GainCell DAC as a complete analog control center with an exceptional performing DAC at its heart. All the features and functions you’d ever want in an analog preamplifier and modern DAC are right here in Stellar. A zero-loss, fully balanced, pure, analog signal path combined with DAC features rarely found at any price level: pure DSD, asynchronous USB, Digital Lens technology, I²S to connect to our best transport, balanced throughout. Replace your preamplifier, your DAC—or both—and be stunned at the level of improvement when the full and rich tapestry of music surprises and delights your senses. Together, or separately, they create an extraordinarily rich, full-bodied musical experience few standalone products can match. The Stellar Gain Cell is the perfect foundation for those unwilling to compromise sound quality. Rich. Lush. Powerful. A music lover’s answer to spiraling cost-no-object equipment without sacrifice. In the more than forty years of PS Audio’s design innovations and breakthrough products, Stellar’s groundbreaking level of performance as our gateway standalone DAC and preamplifier is unmatched for price and performance by their standalone competitors. Taken together, we’re willing to bet you’ve never heard anything quite this good at anywhere even remotely close to this price.

DESCRIPTION
The S300 is an extraordinarily musical power amplifier rated at 140 Watts per channel into 8Ω and 300 Watts per channel into 4Ω. Power enough for even the most demanding speakers. The S300 design marries the best of two worlds: an ultra linear high-current output power stage with a discrete Class A MOSFET based AnalogCell input stage. Between them, the S300 delivers powerful, authoritative control over the loudspeakers, while maintaining a perfectly layered soundstage under the most complex musical passages. Designed by PS Audio engineer Darren Myers, who invested hundreds of hours of tuning, voicing, and perfectionist tweaking, the results are extraordinarily musical. Stellar amplifiers never draw attention to themselves, and are one of our highest value offerings in amplification, a rare quality in amplifiers of any price.
