We're a little late to the party and Stephen from custom IEM has been doing a great job keeping you all informed.  Theres a couple of little kinks that we're still ironing out before these go into full production release, but if you do get a chance to have a listen, please do so!  We've been putting ours through the paces for a while now and it's quite an amazing kit.
 
The PP6 has been added to our global website and our online shop now.  Any questions, just get in touch!  You guys are going to love it.

no passive xover adapter then?
and a phase chart on ciem.com that looks similar to passive xovers on innerfidelity.
so the benefit is the ability for you guys to tune it with less sharp development dips?

> but if you do get a chance to have a listen, please do so!

where?

nice to see it can be a dacamp from pc

There will be passive xover adapters available in the near future.

There will be passive xover adapters available in the near future. 

included in the price or for extra money ?
will it just be in a form of another cable with the xover in the cable?

>nice to see it can be a dacamp from pc

can it do 24b/96k via USB ?

It will come later, and it will be sold separately as an accessory. At least that's the plan for now. These adapters are not easy to make since it involves extra tuning process. It would most likely to take the form of an adapter. 
 
Yes, it supports 24/96 via usb.

There have been a lot of questions about active vs. passive crossovers, so here are some quotes that explain things:
 
Quote from forum.lowyat.net member tunertoobe:

Okay here goes. For passive crossovers, the electrical signal goes through the amp, then the crossover, then the speakers/drivers. The problem with this solution is that it only splits the freq range and NOT the power. They are cheaper to make but produces power loss, and the power amp can't take full control over the speakers. Imagine having an amp produce power for those speakers that have different power requirements. Accuracy of reproducing audio signal over the drivers is therefore affected in a negative way.
 
Active crossovers on the other hand are different. The signal goes through a pre-amp, then goes through an active crossover network. Each output band (bass, mids, highs) will then go through their own separate power amp. That means you have an amp for the bass, an amp for the tweeter and an amp for the mids. This give the power amps full control of their respective drivers/speakers. Meaning, less complex power loading, less freq range for each amp and less power needed from the amp. Overall the audio reproduction of the speakers will be superior.
 
Active cross-overs are the better choice when it comes to Hi-fi but putting it inside an IEM is basically impossible because of the size (imagine putting amps inside IEMs.). It is more common in speakers as a result.  

 
The below quote is in reference to loudspeakers, but still has relevancy IMO.
 
Quote from sound.westhost.com 2.2:

With an active crossover, the amplifier is connected directly to the driver, and the only thing between them is the loudspeaker cable. The amplifier presents the maximum damping factor at all times, regardless of frequency, and is not affected by the crossover network, since that is also active, and located before the power amp.
 
The loudspeaker driver now has the maximum control that the amplifier can provide, across the entire frequency range - not just the crossover network's pass band. The difference in damping is quite obvious, and although some (very well behaved) drivers will show little improvement, the vast majority will be much better controlled, and this will show in an impulse measurement. Not at all uncommonly, it will also show up on a swept sinewave frequency response measurement as well, with the amplitude of peaks and dips generally reduced (albeit marginally in most cases).
 
Well apart from the other advantages of an active system, this is perhaps one of the most compelling reasons to use an active system rather than passive. Not only is it possible to achieve the maximum damping, but if it is determined that a particular driver is best suited to some defined impedance, this can be provided by the amplifier, and will be stable across the frequency range. In some cases, just a series resistor will be sufficient, and even though there will be some power loss, if it makes the driver behave the way it should, then any small power loss is a small price to pay.
 
In short, there is simply no comparison between the two systems. A passive XO will always add (usually) undesirable impedance to that seen by the driver(s), the impedance is frequency dependent, and ranges from perhaps an ohm or so to almost infinite. The potential for uncontrolled cone movement, intermodulation distortion and loss of performance is so great that it is impossible to determine in advance, but it is all negated in one fell swoop by using a fully active system.

Welcome to the party and thanks for the pics!

Want to buy this so badly, the question is...Risk it or wait till someone buys this thing and then review it.

Yeah, alright, but how do THEY sound, uh?
