I'm looking at this chart wondering where my amps fit in.  :scratch:

Tommy, I just sent you an email titled IMPORTANT. I hope you get it before you ship.

John,

I sent a reply.  Your amps are KING Desktop Maraschinos, but with 48V power supplies.  This is essentially the same as upgraded (WBT Gold posts) 48V Desktop Maraschinos, so they would have a $2900 list price due to the upgrade, which is $200/amp.  Thanks.

DAC DAC LED indicators

DAC DAC LEDs, left to right....
Power, valid stream, Fs > 50kHz, Fs > 100kHz

So....
Listening to 44.1kHz: on - on - off - off
Listening to 96kHz: on - on - on - off
Listening to 192kHz: on - on - on - on

    Frequency Response: 0Hz to 150kHz (DC coupled)
    Output Power (standard 750W transformer):
        Stereo Version: 660Wpc into 4Ω, 400Wpc into 8Ω
        MONO Version: 720Wpc into 4Ω, 430Wpc into 8Ω
    Output Power (1500W transformer):
        Stereo Version: 750Wpc into 4Ω, 440Wpc into 8Ω
        MONO Version: 850Wpc into 4Ω, 460Wpc into 8Ω
    Output Power (1800W transformer, predicted):
        Stereo Version, Double Capacitance: 800Wpc into 4Ω, 460Wpc into 8Ω
        MONO Version, Quad Capacitance: 1000Wpc into 4Ω, 500Wpc into 8Ω
    Protection: Thermal, Current, Voltage, Auto-Recovery
    Output Connectors: WBT Gold Binding Posts
    Input Connectors: Neutrik Gold XLR (RCA-to-XLR adapters included)
    Idle Power Consumption:
        Stereo Version: 36W
        MONO Version: 20W
    Sleep Mode Power Consumption:
        Stereo Version: 11W
        MONO Version: 8W
    AC MAINS: 120VAC nominal, 230VAC upon request

MEGAschino Features:
    * Auto-Sleep: Amp sleeps after 8 minutes of no audio and wake up when audio returns
    * Enclosure: Heavy Gauge Steel in Black, Black Faceplate (looks like Classic Cherry)
    * Power Supply: Massive Linear Transformer, separate channel rails with stereo version
    * Remote trigger: 2.5mm DC jack, 3V-12V
    * Ultra-High Sound Quality: Muscular and Graceful

MEGAschino differentiating factors:
 * DC coupling end-to-end ---- response down to 0Hz and NO BASS PHASE SHIFT
 * Low output impedance across the entire audio band ---- other amp manufacturers rate output impedance (or damping factor) only at 100Hz while we measure it at 100Hz, 1kHz, and 10kHz
 * Optimized for SONICS above all else ---- we start with amazing bench specs, like 128dB SNR, then we tweak for sound AFTER that
 * Black background and micro-dynamics ---- 120dB SNR, 0.005% THD+N at low power
 * High power ---- MEGAschino channel boards are capable of comfortably driving up to 1000W into 4Ω and up to 2000W into 2Ω
 * Extended bandwidth ---- up to 150kHz
 * Patented and proprietary circuitry designed in-house ---- we are one of the few amp manufacturers that still designs circuits as opposed to dropping yet another module into a fancy box!
 * No Heat Sinks ! ---- Our proprietary thermal design channels heat into the large steel chassis.
 * Experience ---- Our most important feature is experience.  With more than 30-years of Class-D amplifier design experience, we stand ready to deliver the highest level of technology for truly state-of-the-art performance.
