I've just ordered an ICBM unit. Does anyone know if powering this with a PSAudio PP300 power plant with MultiWave patterns is any problem for the ICBM? I like my sources run through the PowerPlant and am considering the same for the ICBM.

See ya. Dave

This is a very non-tech stab at your question -

The ICBM operates off of a 12v "wall wart" transformer, converting AC to low-voltage DC. I'm not sure that AC power issues would even appply. I have mine powered off of an inexpensive powerstrip, plugged into an always-on receptacle. It's perfectly quiet and clean.

I tried to auto-on the ICBM by plugging it into a switched outlet on my pre-amp, but that resulted in a "speaker pop" when turned on and off. Both Outlaw and the knowledgable folks here advised me that the ICBM is designed to be an always-on device that draws minimal current thru it's transformer.

Hope this helps.

Whether a piece of audio has it's power transformer located outside it's chassis, as is the case of the ICBM and it's wall-wart power supply, or internally, anything that gives the power transformer a cleaner sine wave will make it easier for the piece of equipment to generate clean DC voltage(s) for the audio circuitry.

In the case of linear power supplies (such as the ICBM's), there are waveforms other than pure sine waves that give the rectifier diodes, filter capacitors and regulators an "easier time".

In the case of the ICBM, the wall-wart takes in (about) 120vAC 60Hz from the wall outlet and gives out (about) 16vAC 60Hz to the ICBM chassis where the ICMB rectifies, filters, regulates, and filters again to get the DC voltag(s) needed by the active cirtuitry inside the ICBM.

The PSAudio P300 and the ICBM will work fine together. The type of powersupply that the ICBM has is the type that the P300 works really well with. Beings I don't work for PSAudio, I can't claim that the P300 was designed for the ICBM's type of power supply, but if it wasn't, I'd be suprised.
