Approximately 6 years old, customer upgraded recently to APEX monos. Come in flight cases.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eOf course, being Gryphon aficionados and, therefore, by definition, connoisseurs of the finer things in life, Gryphon owners immediately began speculating about what the next step might be for Rasmussen and his adventurous band of engineers and audiophiles. Nothing exceeds like excess, as an old saying goes.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eNow, for the most demanding among the fortunate few who make up the Gryphon audience, for that limited circle able and willing to travel with us all the way on our journey, Gryphon presents the Gryphon Mephisto Solo single-channel power amplifier.\u003c\/p\u003e\n\u003cp\u003eWhile monoblock construction is not unheard of in the High End, most often manufacturers take the easy way out, by simply creating a bridged version of an existing two-channel product. Bridging couples the stereo channels in series to form a single amplifier with increased voltage and, nominally, more output power. Unfortunately, the inevitable side effects of this approach include doubling distortion, doubling the input impedance (impairing the amplifier’s ability to drive low-impedance loudspeaker loads) and cutting damping factor in half (reducing the amplifier’s control of cone motion at low frequencies).\u003c\/p\u003e\n\u003cp\u003eThe Gryphon Mephisto Solo elegantly eliminates these issues by running two stereo channels in parallel (not in series) for unchanged output and voltage, but double the current and half the distortion. As always, extreme high current capability is a fundamental parameter in Gryphon amplifier design.\u003c\/p\u003e\n\u003cp\u003eCapable of massive current swings, Gryphon Mephisto Solo maintains the dynamic integrity of the audio signal even under the most extreme reactive loudspeaker load conditions. The extraordinary load tolerance of the Mephisto Solo means that it will bring out the best in any loudspeaker.\u003c\/p\u003e\n\u003cp\u003eIsolating power amplifier channels in completely independent enclosures offers additional crucial advantages. With separate power supplies, rectifiers, regulation, preamp stages and gain stages, there is no interaction whatsoever between channels. What happens in one channel at any given time (for instance, extreme instantaneous dynamic demands) is entirely independent of and therefore unaffected by anything going on in the other channel.\u003c\/p\u003e\n\u003cp\u003eTotal physical separation of the channels eliminates any possibility of inter-channel crosstalk, providing infinite stereo separation.\u003c\/p\u003e\n\u003cp\u003eAs a result, the Gryphon Mephisto Solo drives loudspeakers with greater ease, control and authority, delivering a more spacious soundstage in all dimensions, rich detail against a silent background and tighter, more extended bass. Less critically, independent mono amplifiers offer increased flexibility of placement in the listening room.\u003c\/p\u003e\n\u003cp\u003eThe quality of sound reproduced by Gryphon Mephisto Solo is completely level-independent. It is a huge amplifier capable of delivering its best at any volume setting, from background levels to full throttle.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"vc_row wpb_row vc_row-fluid dt-default mpc-row\"\u003e\n\u003cdiv class=\"wpb_column vc_column_container vc_col-sm-12 mpc-column\" data-column-id=\"mpc_column-935cb5d316d37c4\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003ch2\u003eA Peek beneath the Hood\u003c\/h2\u003e\n\u003cp\u003eTo generate and control such pure power, Gryphon Mephisto Solo employs custom designed Holmgren transformers with generous filtering capacity for high pulse current. The fully regulated gain stage power supply ensures long-term reliability and safety.\u003c\/p\u003e\n\u003cp\u003eThe carefully regulated and filtered power supply removes harmful high-frequency noise and voltage spikes without compromising current capacity. The complete removal of mains noise enhances focus, immediacy, transient crispness and soundstage depth.\u003c\/p\u003e\n\u003cp\u003eGryphon Mephisto Solo is designed with zero global negative feedback in order to meet the dynamic demands of the very best analogue and digital source components. Exceptional bandwidth – beyond 350 MHz – is achieved despite the total elimination of feedback.\u003c\/p\u003e\n\u003cp\u003eOnly the finest components are employed throughout for optimal electrical and audio characteristics. The voltage amplification stage incorporates high-speed Zetex surface mount transistors with minimal capacitance and high DC current gain (Hfe) and the output stage employs high-speed Toshiba pre-driver transistors.\u003c\/p\u003e\n\u003cp\u003eA fully symmetrical, regulated low noise voltage supply has been used for all voltage amplification sections. For each monoblock, eight 56,000 microFarad capacitors with low ESR (Equivalent Series Resistance) and a total capacity of 448,000 microFarad\/100V smoothes the voltage to the output supply.\u003c\/p\u003e\n\u003cp\u003eStatic shielding isolates primary and secondary windings in the massive dual Holmgren transformers designed and built especially for the Gryphon Mephisto Solo.\u003c\/p\u003e\n\u003cp\u003eBy eliminating output relays, Gryphon Mephisto Solo achieves an extraordinary low output impedance. But most importantly, because output relays that can handle huge constant currents tend to have poor low to moderate signal transfer characteristics, the best relay is quite simply no relay at all.\u003c\/p\u003e\n\u003cp\u003eAs always with Gryphon, what is left out is just as critical as what goes in.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"vc_row wpb_row vc_row-fluid dt-default mpc-row\"\u003e\n\u003cdiv class=\"wpb_column vc_column_container vc_col-sm-12 mpc-column\" data-column-id=\"mpc_column-375cb5d316d3c11\"\u003e\n\u003cdiv class=\"vc_column-inner\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003cdiv class=\"wpb_text_column wpb_content_element\"\u003e\n\u003cdiv class=\"wpb_wrapper\"\u003e\n\u003ch2\u003eNon-Invasive Protection\u003c\/h2\u003e\n\u003cp\u003eMephisto Solo is equipped with effective protection against overheating, DC input offset, short circuit, RF and incorrect voltage supply.
