The analog power supply incorporates a small toroidal transformer with plenty of linear voltage regulators. The clam-shell chassis with locking side rails allows the vertical heat sinks to wedge snugly against the top panel since it won't have to slide across them to wreak havoc. The top cover simply gets laid on, secured to the rear panel, then the connective rails insert and the front panel completes the box assembly.
Input selection includes analog line in and digital coax, optical, AES/EBU and USB. Power modes include on and standby.
Here we see voltage regulators mounted to aluminum heat sinks.
Here are the power stage output devices.
Here is the Libby circuit in its entirety.
Rubby duplicates Libby's inputs but replaces the headphone/preamp output stage with a beefier 44/60wpc into 8/4-ohm speaker-drive affair. All digital inputs—USB, SPDIF/AES-EBU and Toslink—have support up to 24-bit/96kHz. The output stage TI TAS5606 PurePath™ power processing chip meanwhile can handle input rates from 32 - 192kHz. Requiring from 10 to 26V rails, supply voltages are generated by a laptop-type Li Tone Electronics model LTE120E-SR-1 SMPS with universal 100-240Vac 50/60Hz input and 30Vdc/4A delivery with a max rating of 120W.
The actual power processing chips are tucked between mother board and finned heat sinks to elude visual inspection.
It's unclear what the presently unused twin 10-pin connectors are for.
