Soulution Audio 727
Image source - (c) Soulution Audio
Position in line
It belongs to Soulution Audio's preamplifier range.
Key specs that matter
Three balanced and two single-ended inputs are provided, with two balanced and one single-ended output. Input impedance is 4,400,000 ohms for both connections. Output impedance is 0.8 ohms balanced and 0.4 ohms single-ended. Output voltage is 14 V balanced and 7 V single-ended. Rated bandwidth reaches 20 000 000 Hz. Signal-to-noise exceeds 120 dB. At 480 x 450 x 167 mm the chassis weighs 28 kg.
Pairing
The high input impedance suits virtually any source component without loading concerns, and the 14 V balanced output gives ample drive for a power amplifier.
Alternatives
Soulution Audio's 525 is an alternative preamplifier in the brand's range.
