The Story
The loved and respected M15 format was perfect for Questyle Audio to debut its first Cirrus Logic DAC. M15C employs the increasingly popular CS43198 DAC/amp and partners it with its trademark current-mode amplification.
With MFi certification for guaranteed compatibility with Apple products, and the power needed to drive the low impedances of the latest flagship earphones, M15C could be the only dongle you'll need.
Unlike any other dongle DAC/amp, Questyle's current-mode amplification eliminates the lag time of the signal that might otherwise occur, as it builds up at the capacitances in the circuit – current signal passes through unhindered as compared to voltage, with speed and ease. [See Product Desc. For More]
By doing away with the issue of transmission delay in M15C, Questyle virtually eliminates any of the harshness caused by the intermodulation distortion associated with high capacitance, solid-state circuits.
M15C decodes digital via its Cirrus Logic CS43198 DAC smoothly and organically, without exaggerated warmth or bloat.
That small signal then takes advantage of being unhindered by capacitance in the signal path. An added benefit from current-mode amplification is that huge signal bandwidth is possible, leading to phase response being accurately preserved in the human hearing range.
Indeed, to hear current-mode is to hear a naturalness to music not encountered before in a conventional circuit, and Questyle build M15C as an affordable entry to such a topology.
Happily use with any low-impedance device (current signals excel the closer a load is to ground) such as Rosson Audio Designs, the Vision Ears Elysium EXT, plus CIEM heavyweights Craft Ears and Empire Ears – particularly the latter's Triton, Odin and Legend Evo.
Driving low impedances is M15C's forte. But bridge-tied load balanced operation now means this dongle also doubles voltage swing compared to single-ended operation, to drive higher impedances credibly too.
For an ESS Technology flavour, you can look to Questyle's M15i here. Or, explore how Questyle's current-mode scheme in can further benefit your planar-magnetic headphones in CMA18P, or browse our other mobile DAC/amps here.
