This is the thread to submit your name for the NEW Apex HiFi Audio Headphone Amp/ Preamp!!!Come and be the first to hear it at RMAF next weekend!Name the P2X!
The new Apex HiFi "P2X" - a code name that will be replaced with the best name chosen by YOU at RMAF - is an all-new tube hybrid design preamp and headphone amp. Help us pick the winning name and you will win the very first production "P2X"!
About the P2X
Instead of a stepped attenuator or volume control pot, the P2X uses a digitally controlled attenuator using relays and fixed resistors. This volume control gives nearly perfect attenuation and channel tracking, with 1dB steps, down to -63dB.
Three inputs are provided, with two sets on RCA connectors at the back and one a 1/8" jack on the front (to connect a phone or music player). In addition to the headphone jack on the front, RCA outputs on the back provide a preamp output to drive powered speakers or a full stereo system.
All functions of the P2X can be accessed with a single control knob on the front of the enclosure, or by an infrared remote control (included). Multicolored LEDs on the front of the P2X indicate the volume setting, and by their color, the active input.
The P2X can use many different tubes. The standard tube is a JJ Electronic ECC802S. Other tubes that work include any type of 12AU7 or ECC82, 5814, 6211, 5963, 6680, 7057, and 12BH7 tubes.
1. Submit your suggested name on the Head-Fi website in this thread. One name per person, please.
2. It is suggested that in keeping with other Apex HiFi products, the name be a term related to topography, geology, or geography. Place names are OK, as are names in a language other them English.
3. In the event that the winning name is submitted by more than one person, the first person to submit it will win.
4. The winner will be chosen by Todd and Pete, and announced Saturday night in the CanJam room at RMAF. You need not be present to win...
