    Questyle M12Questyle M12

    Questyle M12

    Questyle Audio adhere faithfully to current-mode amplification at all form factors, their dedication to this technology extending down to their thumbdrive-sized DAC dongle, the M12.  It's easy to hear why, if audible results count to you. Operating in current-mode, audio signal gets passed in current instead of the more standard voltage. This 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 M12, Questyle virtually eliminates any of the harshness caused by the intermodulation distortion associated with high capacitance, solid-state circuits. Typical of their high-end offerings, M12 presents detail smoothly and organically without exaggerated warmth or bloat. It easily earned Stereophile's praise for its transparency. Another effect of being unhindered by capacitance in the signal path means 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 M12 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 Focal's new line of headphones – Radiance, Celestee and Clear MG – plus Rosson Audio Design and CIEM heavyweights Craft Ears and Empire Ears. // GOOD TO KNOW  Current Mode Amplification Smart impedance matching from 8 to 600 Ohms.

    Questyle M15

    Questyle Audio adhere faithfully to current-mode amplification at all form factors, and building a 4.4mm balanced output into the M15 just extended the capabilities of their flagship dongle. Headfonia says "M15 offers one of the most sophisticated designs in the industry". ecoustics rate it on par with legacy music players and "would suggest trying it before you pay for anything else". MOONSTAR Reviews echo M15 competes on equal terms as music players. Headphonesty hail it as liquid gold. M15 "managed to wring musicality out of the ESS DAC chip that I frankly did not think possible" praised Headphone Guru. It's easy to hear why, if audible results count to you. Operating in current-mode, audio signal gets passed in current instead of the more standard voltage. The Legend Evo from Empire Ears provides instant synergy, given its 3ohm load. 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 M15, Questyle virtually eliminates any of the harshness caused by the intermodulation distortion associated with high capacitance, solid-state circuits. Typical of their high-end offerings, M15 decodes digital via its ESS Technology ES9281AC 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 M15 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 Odin and Legend Evo. Driving low impedances is M15'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.

    Questyle CMA15Questyle CMA15

    Questyle CMA15

    CMA15 celebrates the 15th anniversary of Questyle Audio's inception with the use of ESS Technology's flagship ES9038Pro DAC. ecoustics say the benefits of a natural union of current-mode technologies are audible, placing CMA15 at the top for your consideration as a line source and headphone amplifier. CMA15 packs one of the most sophisticated pure Class A analog stages in a DAC available to market now, the strengths of an ES9038Pro and CMA15's current-mode amplification working hand in hand. CMA15 is alive with tone colour and saturation, notes propelled forth with a real zeal and macro-dynamic force about them. There is a tangible physicality about this Questyle flagship – listeners enjoy a palpable connection hearing familiar music again, as CMA15 heaves and breathes like it were a real, living, being. And still, in a reference DAC where neutrality is so prized, it presents tonal balance accurately. [See Product Desc. For More] In a throwback to Hi-Fi luminary Dan D'Agostino's work [using Texas Instruments] for Krell Industries at the beginning of the 21st century, Questyle designed CMA15's analog circuit path to operate transmitting signal solely in current instead of the standard voltage, starting from its ES9038Pro's 50mA analog current output. Manufacturers have long taken advantage of the ESS flagship's claim to be the most sophisticated DAC chip available, outputting in current for best distortion figures before traditionally voicing the circuit through the crucial I/V current-to-voltage converter stage. But D'Agostino understood then that no I/V stage could completely disappear sonically, colouring the sound artificially in ways unacceptable – he therefore removed the stage entirely, by employing Krell's own current-mode analog circuit. Transmission of signal, entirely in current, without prior conversion to voltage, has been revived by Questyle to the same effect here. Removal of the I/V aspect of CMA15's circuit therefore sees the purest expression ever of Questyle's current-mode philosophy, keeping affairs post-digital conversion magnificently and elegantly simple with fewer parts necessary.  Questyle's choice of current-mode signal is the stuff of legend by now. It eliminates the lag time that might otherwise occur when signal is transmitted in voltage, as it builds up at the capacitances in the circuit – current signal passes through unhindered by comparison, with speed and ease.  By doing away with the issue of transmission delay in CMA15, Questyle virtually eliminates any of the harshness caused by the intermodulation distortion associated with high capacitance, solid-state circuits.  Coloured yet correct, CMA15 presents detail smoothly and organically with a sense of vibrancy that's accurate and still entertaining. Another effect of being unhindered by capacitance in the signal path means 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 CMA15 as the ultimate expression to such a topology.  A 4.4mm headphone output, a pure Class A small signal and power stage, and LDAC Bluetooth input, allow users to enjoy CMA15 in ever more scenarios. Current-mode will prove even more effective the closer a load is to ground. The results translate to an ultra-low distortion, linear, analog system in tandem with Class A, without resorting to the excessive use of negative feedback. CMA15 works as a perfect DAC for your Hi-Fi system into component input impedances that have been dropping ever more readily since the turn of this decade. Flip CMA15 to variable volume mode, and its analog potentiometer turns it into an excellent pre-amp. Everything above discusses the less-obvious about a true Questyle flagship, because the plain truth is that CMA15 functions as the perfect headphone amplifier first and Hi-Fi hub second.
