What if we made a Class A version of the Vidar? No, wait, strike that. What if we made a better-than-Class-A-in-many-respects version of the Vidar? Well, here you go. Meet Aegir.
Continuity™: Benefits Beyond Class A
Aegir is our first Continuity speaker amplifier, extending a technology we introduced with the Lyr 3 headphone amp. Technically, Continuity is a way to eliminate transconductance droop outside of the Class A bias region, and extend the benefits of Class A biasing. It also solves the NPN and PNP device mismatch problem, since it uses both NPN and PNP devices on both rails. It’s still a very hot-running amp, though, with over 10W of Class A standing bias.
A True No-Excuses Design
Like Vidar, Aegir uses an exotic current-feedback topology, as well as a 100% linear power supply (with 7 separate voltage rails and 600VA transformer) and microprocessor oversight to eliminate capacitors and DC servos in the signal path. No Class D, no switching supplies, no fans, no compromises, nothing in the signal path but music—for a three-figure price tag.
Power That Scales
Aegir provides 20W into 8 ohms, doubling to 40W into 4 ohms. Run mono, and you’ll see 80W into 8 ohms and 120W into 4 ohms. Best of all, Continuity ensures you see Class-A-like performance at all these power outputs.
Convenient Standby Mode
On Aegir, we’ve added a front-panel button to put the amp into Standby mode. This de-biases the output stage completely and reduces standing power consumption from 200W to about 15W. This keeps the rest of the amp up and running, without massive heat output.
Designed and Assembled in USA
By “designed and assembled in USA” this is what we mean: the vast majority of the total production cost of Aegir—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.
