Headphoneus Supremus
from the manufacturer's specs page:
Bands: 20Hz, 120Hz, 400Hz, 2kHz, 6kHz, 16kHz
Adjustment: +/-12dB at 20Hz and 16kHz, +/-9dB at 120Hz and 6kHz, +/-6dB at 400 and 2kHz
Maximum Output: 10V RMS (SE), 20V RMS (balanced)
Frequency Response: 20Hz-20Khz, -0.1db, 2Hz-1MHz, -3dB
THD: Less than 0.0008%, 20Hz-20KHz, at 2V RMS in/out, pots centered, active stage enabled, less than 0.002% at any potentiometer setting
IMD: Less than 0.001%, CCIF
SNR: Greater than 115db, unweighted, referenced to 1V RMS
Crosstalk: -85dB, 20Hz-20KHz
Output Impedance: 75 ohms
Input Impedance: 47K ohms
Topology: discrete, all-bipolar, symmetrical current-feedback design with matched parts throughout, DC coupled, with DC servo, plus dual-stage discrete superbuffer
Filtering: capacitor-gyrator for 20Hz and 120Hz, capacitor-inductor (LC) for all other bands
Power Supply: “Wall wart” style 16VAC transformer, dual regulated +/- 17V rails
Power Consumption: 6W
Size: 6 x 9 x 1.5”
Weight: 2 lbs
----------------------------------------------
my initial impressions:
Setup:
connected SE in / out (RCA) to Bifrost OG (gen 1, multibit) below the Lokius, and Asgard 3 (above the Lokius);
power via included Schiit-branded AC wall brick, 16VAC 1000mA rating.
hum and noise:
with all control knobs set to middle detents, noise and hum sounds the same in both Bypass and Process modes, despite the stacking above to BF1 & A3.
sound quality:
Unit is very transparent sounding with all knobs set to center.
Bands seem well chosen, esp the 120Hz control, which was lacking on the smaller Loki Mini units.
(added)
Mechanicals / Build Quality:
unit was packaged in brown corrugated box, sealed with Schiit-Texas logo packaging tape (nice touch!) and protective 3-D foam bumpers on both ends, plus an extra corrugated cardboard layer between unit and the white boxed wall wart AC transformer-- typical high-quality Schiit packaging.
As shipped, all controls set to mid detent, and all rotated very smoothly without any knob/front panel interference. Knob pointers aligned pretty well with 12:00 position when detented.
Very good assembly quality out of the new Corpus Christie facility.
Power On LED is very bright especially in a dimly lit room / at night, like many Schiit products.
