Description
The original first version Aegir. Excellent working condition with no blemishes. Boxed with power cable and custom speaker cables. Purchased directly from Schiit USA in Valencia, CA 91355 in late 2023. This is the 1st of 2 identical Aegirs I have for sale. If buying both, I will send a $20 discount off the unit price. From SHIIT website: 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. Its 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 youll see 80W into 8 ohms. Best of all, Continuity ensures you see Class-A-like performance at all these power outputs. Convenient Standby Mode On Aegir, weve added a front-panel button to put the amp into Standby mode. This de-biases the output stage completely and reduces standing power consumption significantly. This keeps the rest of the amp up and running, without massive heat output. Designed and Built in California By “designed and built in California” 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. Power Output: Stereo, 8 Ohms: 20W RMS per channel Stereo, 4 Ohms: 40W RMS per channel Mono, 8 ohms: 80W RMS Frequency Response: 20Hz-20Khz, -0.1db, 3Hz-500KHz, -3dB THD: <0.01%, 20Hz-20KHz, at 20W RMS into 8 ohms IMD: <0.01%, CCIR, at 20W RMS into 8 ohms SNR: >114db, A-weighted, referenced to full output Damping Factor: >100 into 8 ohms, 20-20kHz Gain: 12 (22dB) Input Sensitivity: AKA Rated Output (Vrms)/Rated Gain. Or, 14.3/12. You do the math. Input Impedance: 22k ohms SE, 44k ohms balanced Crosstalk: >105dB, 20-20kHz Inputs: L/R RCA jacks for stereo input, single XLR for mono input Topology: Fully complementary, all-BJT, current feedback, no coupling capacitors or DC servos with Continuity™ constant transconductance output stage Oversight: microprocessor-controlled monitoring and management of critical operational points, including DC offset, with standby mode and relay shut-down for overcurrent, thermal, and other faults Power Supply: 600VA transformer with dual mono main rails, plus boosted, regulated supply to input, voltage gain and driver stages, plus separate, isolated and regulated rails for microprocessor management. Power Consumption: 450W maximum Size: 9” x 13” x 3.875The custom made cables are by BlueJeansCables - my preferred cable maker in USA. Cables is Belden 10 gauge (6 ft) and have locking bananas on both ends. Since I used the Aegirs as mono blocks (80W ea) I have two cables only. If you buy one amplifier I can charge a small amount for the cables, if you buy both amps then cables are free (a $110 value). The Aegirs drove my Focal Arias 948 for a year with absolute ease and transparency. One can read professional evaluations from Stereophile or Hifiplus.
