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.
 
The Rules
 
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...

Hi.  What are the Power specs into 300 and 600 Ohm loads? And the projected retail price?
 
Cheers.

What ever happened to this amp ?  Was production a no go ? Did the winner of this contest receive his amp ? If so, did he sell it (not listed in his profile) ?
Sorry if I seem nosy, I did enter this contest, and today I went to TTVJ to see if it was in stock and there is no sign of it, that I could find.

Todd told me they are not putting the amp into production so in fact the one I have is a one of a kind product.

Let's get this party started! I just received the P2X, but I've loaned it to a friend. It comes only with 3.5mm outputs on the front- no 6.5mm. So naturally my friend is using it with a resistor with his IEMs, and is gonna be in here in a bit with impressions. :) Stay tuned!!

The P2X is really amazing guys. It gave my w500 much more wholeness and it's very clear yet there's that tinge of sweetness there. I wonder why they didn't continue with this amp. Probably the best I've heard so far as compared to the CDM and Auralic Taurus that I had.

Thanks for the impressions, I see you're using it with a 3.5mm out from your dap. Interesting, I do kinda wonder if they had meant for this to be a transportable amp. Impressive that it beats your Taurus as well- that amp is certainly no slouch. Apart from your w500 does it have good synergy with other iems?
