The in-line Kameleon filter is an active equalizer with easy to insert modules that are taylored for specific headphones. The device goes between any source (as long as it is around line level) and your headphone amp. It corrects the frequency response of certain headphones (those where filtermodules have been designed for) so the tonal balance becomes more even. When you absolutely adore the tonal balance of your headphones as they are and like them for their coloration than this is not for you.
When you like your headphones but would love them to not have that peak in the treble or to have a better extension or more ‘correct’ tonal balance and you don’t want to (have) your headphones modified and don’t want (or can) use digital EQ then this might be your answer.
This is intended as a D.I.Y. project. Bare PCB’s (so without components) are available. To order them contact me via the contact form .
prices of bare (not populated) PCB’s: Kameleon in-line board (black) = sold out Filter Module PCB (SMD, black) = € 2.85 Crossfeed Module PCB (SMD, green) = € 4.60
Shipping costs depend on weight and destination. Goes through ‘normal’ mail in an envelope so NO exhuberant shipping costs of just a few Euros max.
Both the silver and black prototypes are were for sale, both are now sold.
The silver one has vertical action switches the black one has horizontal action switches.
When you buy one I can set the 'on' positions of the switches to your preference. Will also include 1 or 2 filter modules of your choice and a connection cable to connect to any G1217 amplifier. Can also be used with other amplifiers but then you will need to buy a 24V power supply for it.
No idea if and when a G1217 version will become available and what it will cost.

Believe you plug the Ember's PSU into the back of the Kameleon and then you run another short connecting lead from the Kamleon to the Ember. Imagine the construction guide Frans has linked will give you specifics on the connecting cable.
I think that you have to remember Aakshey, that Frans is not a retailer. He is a private individual who has designed these filters and made them for testing.
If you are worried about things like guarantees et cetera then it might be better to wait for it to actually be released by a retailer like Jeremy. Having said that I really don't think that Frans will send a unit out that was not working. Well, I know that he wouldn't!!!
We seem to forget that Frans is an individual member and not a retailer. I reckon that he is providing these units for sale for people similar to me who can't put the bloody things together!! (Well actually, I probably could but nothing like as neat as Frans does!!!! ) Check my helis and you'll see how neat I am!!!
So really, they are second hand in that respect and you need to wait for Jeremy in order to get new ones with shop guarantees and return policies....
I have no idea IF and WHEN Jeremy will sell them and for which price when they become available. It does not exist yet in G1217 style. Will have to design it first.
Shipping prices always depend on the shipper and kind of shipment (tracked, insured, signed for), and weight. As none of this is known (as it simply does not exist yet) and don't know how Jeremy ships his stuff it is safe to say... I don't know.
When the Kameleon becomes available all pricing will undoubtably be shown on G1217 website.

Welcome. Quick messages/chats but this area is emptied from time to time so nothing permanent here!!
lobalwarming: But, let's say it's a live rock or jazz band with multi mic mayhem. Most of the phase response of the live performance has already been mortally wounded, and we haven't even made it to the mixdown
Sept 3, 2019 4:03:51 GMT
lobalwarming: Then the recording is mixed in a studio, hopefully with decent monitoring and a mix engineer who hasn't blown his ears out.
Sept 3, 2019 4:05:32 GMT
lobalwarming: After the mix engineer has finished the mix to his/her satisfaction (which means bias), then the mastering engineer takes a whack at it because the mastering engineer doesn't like the biases/tastes of the mix engineer.
Sept 3, 2019 4:08:14 GMT
lobalwarming: Quite likely neither mix engineer nor mastering engineer attended the live recording (unless a boutique label).
Sept 3, 2019 4:09:13 GMT
lobalwarming: Also... the mix & mastering engineer are normally using speakers to monitor and 'optimize' the recording for. Very, very, very few optimize for headphone listening.
Sept 3, 2019 4:14:24 GMT
lobalwarming: Making a really high quality recording that reflects the live performance sonics is really hard. So many places it can go wrong.
Sept 3, 2019 4:15:52 GMT
lobalwarming: The recording/capture/manipulation/production determine about 90% of the ultimate quality. Our little playback chains get to play with the last 10%.
Sept 3, 2019 4:17:24 GMT
lobalwarming: Since there is no perfect headphone, amp, DAC, mic, preamp we have to decide what elements of the live performance we want to focus on
Sept 3, 2019 4:23:02 GMT
lobalwarming: That focus can change depending on our mood/time of day and dozens of other subjective variables
Sept 3, 2019 4:24:47 GMT
lobalwarming: Some days I enjoy the BP ECC40 more, because it's exceptionally transparent and (with a phase-preserving recording) can accurately reproduce a sense of 3D space with excellent depth perception and precise imaging.
Sept 3, 2019 4:26:42 GMT
lobalwarming: Imaging that is a fake, of course. Because stereo is a crude approximation.
Sept 3, 2019 4:27:46 GMT
lobalwarming: Other days, I enjoy the ECC32 more, because its nature enhances the 'experience' - it often feels more engaging despite knowing it too is a fake engagement.
Sept 3, 2019 4:29:57 GMT
lobalwarming: Our brains are amazing at sensory pattern matching and our imaginations can fill in many details. But our brains are easily distracted and often distracting - messing with attention with random thoughts and/or filtering out stimulus.
Sept 3, 2019 4:32:27 GMT
lobalwarming: And before I'm banned from the shoutbox for filling all the boxes... even if I could definitively claim the ECC40 or ECC32 is better than the other, that's just me. Could be that you prefer entirely different tubes and I'm a tone-deaf idiot. ;-)
Sept 3, 2019 4:38:45 GMT
lobalwarming: What I love so much about headphone listening is that it's personal. I can tweak my system to satisfy only my whims, not the collective opinions of friends or the internet
Sept 3, 2019 4:39:59 GMT
lobalwarming: I've bought many tubes, that many claimed were the 'best', only to listen on my system with my ears and decide they were closer to the worst for me. That's why I state it as flavours. There is no objective standard that we all can agree on for live music
Sept 3, 2019 4:42:28 GMT
lobalwarming: Some prefer to be closer to stage/musicians and others prefer the sound blended with some hall acoustics and sit further back.
Sept 3, 2019 4:44:31 GMT
lobalwarming: As a recordist, which spot is the 'best seat in the house'? It's subjective.
Sept 3, 2019 4:45:08 GMT
sene: Thanks for sharing your ideas and opinion...i will give these tubes a try
Sept 3, 2019 4:58:01 GMT
lobalwarming: The ECC31 is the same construction as the ECC32, but for the heater config. The ECC31 with an adapter will still be much cheaper than the ECC32. Which will let you save up for a 1st gen unicorn Black Plate Phillips ECC40 ;-)
