Quotes

...I asked George to sum up his design philosophy for the Leto: "A preamp should be as neutral as possible and not add any components that could compromise the signal. For example, there are no transistors anywhere in the signal path. All the switching is done through reed relays."
Footnote 3: The Modern Dictionary of Electronics (Howard Sams, publisher) defines hysteresis as (definition #5) "A form of nonlinearity in which the response of a circuit to a particular set of input conditions depends not only on the instantaneous values of those conditions, but also on the immediate past (recent history) of the input and output signal. Hysteretical behavior is characterized by inability to 'retrace' exactly on the reverse swing a particular locus of input output conditions...This term literally means to lag behind." Robert Harley
...Although the "hardware is principally designed to be able to operate up to 192kHz" per Illusonic, and the IAP can accept signals up to 192kHz via HDMI and 96kHz via S/PDIF, the IAP's internal signal path is 24/48...
"-thick metal I-beam that extends the player's full depth. Four 6H30 dual-triode tubes drive the analog section; a fifth 6H30 and a 6550C regulate the power supply. ARC claims that its use of four digital-to-analog converters (two per channel, each in dual-mono mode) reduces the digital noise floor by 3dB (ie, doubling the number of DACs doubles the signal's amplitude while keeping the noise the same). Power is handled by a custom transformer that, according to design engineer Dennis Petrich, has no gaps or breaks in the material of its R-core and thus more efficiently contains the flux field, with much less leakage, resulting in less distortion and a higher signal/noise ratio. Jitter reduction (to <10 picoseconds, according to the spec sheet) is handled by a crystal-controlled reclocking mechanism."
