Two Giants from Constellation Audio: Statement Mono Amplifier and Statement Stereo Amplifier
19.01.2025 06:44 | ~2 minutes read
The flagship High End power amplifiers from Constellation Audio, the Statement Mono Amplifier and Statement Stereo Amplifier, use a whole clip of the company's innovations and provide outstanding sound quality.
The Constellation Audio Statement Mono Amplifier is based on the Constellation Switched-Mode Power Supply (C-SMPS) with Power Factor Correction (PFC) technology. The circuit guarantees 380 V power at any AC voltage standard, with the voltage and current always in phase. This approach guarantees absolute tolerance to loudspeaker impedance, which is not possible with traditional transformer-based linear power supplies. The noise level in the new power supply, again, is reduced by more than 20 dB.
The Statement Mono’s output stage with 96 output transistors offers 1 x 1,700 W of power into 8 Ohms, 1 x 3,400 W into 4 Ohms. If this seems insufficient, combining two Statement Monos in bridge mode will give 1 x 6,000 W.
Another interesting feature of the model is a fully balanced, mirror-imaged input stage with paralleled amplification modules - this scheme reduces noise by additional 5 dB. The weight of one amp, 114 kg, clearly hints at the extraordinary engineering.

The Constellation Audio Statement Stereo Amplifier uses the same set of proprietary technologies (for example, Constellation Switched-Mode Power Supply with Power Factor Correction) as the Statement Mono described above. Only now the model demonstrates a slightly "reduced" power - 2 x 850 W into 8 Ohms loudspeakers, 2 x 1,600 watts into 4 Ohms speakers impedance load, and rises to 2 x 3,000 W when the amplifier is bridged. The Statement Stereo Amplifier also weighs 114 kg.

Soulution has introduced the ultimate vinyl player Soulution 787. The model features linear tracking system with a moving platter and a minimal excursion pivoted tonearm.. Recall that such designs imply the highest tracking accuracy, but have hardly been used until now due to their extreme complexity and high cost (Nakamichi TX-1000 Computing Turntable in 1983-1987 with Absolute Centre Search System offered offered something a little similar - but in that case the tonearm moved, and the platter provided the necessary center shift, corresponding to a specific LP).
