ADAGIO 520B SINGLE ENDED MONOBLOCKS
The advantage of parallel single end design, twice the power with little increase in distortion. Twice the current for the same voltage, and of course a larger damping factor.
The Adagio uses our unique SENTRY CIRCUIT Electronic over current protection with soft start, this device puts the amplifier into standby mode until any fault is removed and prevents the electronics being damaged under valve failure conditions.
Separate choke filtered power supply for each output valve, 2 per mono block.
Automatic bias control, no setting up, power valves must be matched.
In the Adagio we use Hovland Musicaps and 1% metal film resistors (upgrades versions available)
As with all our amplifiers, we take great pride in our output transformers, recognising that in many ways, they are the defining part of any valve amplifier. In the Adagio they are really special, with a large core (400 wt capable) designed for high damping, split bobbin multi section with grain orientated laminations.
Our ultimate single end amplifier with awesome dynamics and exceptional linearity sensational 3-D sound staging brings the live event right into your living room, with all the emotion the musicians have mastered in their performance.
