APL1 Gold
APL1
Tube Line Preamplifier
The APL1 tube line preamplifier has been designed for those who demand the best possible sound quality second only to our Reference APL01SE Preamplifier.
The APL1 is the mid-priced device in the Riviera preamplifier range and, like all of our preamplifiers, it shares the same basic design choices: all-valve, Zero Feedback and Class A audio circuitry.
The APL1 is equipped with a refined double pigreco and stabilised anode power supply; in this preamp there are a total of five stabilised supplies. It also employs several design elements adopted from the Reference APL01SE preamplifier including output balance control and the use of custom output transformers that operate on both balanced and unbalanced outputs ensuring consistent and superior sound quality.
The mechanical construction of this unit has been meticulously crafted, as Riviera believes it significantly impacts sound quality.
