The sound will be the same because it's the same filter. The cost will be different depending on enclosure and power supply.
The Kameleon is a filter and AMPLIFIER, all in one box.
The filter for the Garage amps is JUST A FILTER since you already have an amp after it. It just connects in line but it has to be connected to an amp.
So the Kameleon is actually another amplifier with a filter built in instead of having a separate module.
The filter will be able to be bypassed on the Garage set up so you can just use any headphone as normal with one filtered if you like. The Kameleon has the filter built in and I'm not sure whether it can be bypassed, so it is kind of dedicated to one headphone unless you want to keep changing the filter for each headphone that you use.
No one has cost it out properly yet and the Garage filters ones haven't even had a release date yet, since Jeremy has been working on a power supply.

I'll prefer the portable amp n filter version. Will Frans still make and sell it even if Jeremy sells the Garage style filter?

I will not sell completed amplifiers, only bare PCB's.
The Garage 1217 filter is a totally different product and does not exist yet, there is only a schematic drawing for now (not published)
For US customers G1217 will also build Kameleons (on request for a price determined by G1217)
For EU customers Javier will provide built Kameleons (on request for a price determined by Javier).
For now they ONLY exist when you build them yourself.
Ready made ones will probably be available (on request only, not from stock) from around April 2016.
The G1217 filter ... everything is UNKNOWN

Thanks for your explanation Rabbit. A fixed parametric equalizer developed from accurate measurements sounds about right. I had a Yamaha preamp long ago with a parametric equalizer, I could target a center frequency and then adjust the with and amount of boost or cut. It was fun to play with for a while but without any measurement devices or room correction software i ultimately left it zero'd out. My sister and law still has it. I can pretty much guarantee she doesn't use the feature either. Ha Ha So I guess the last question is whether the Kameleon would be supplied for a specific headphone based on measurements taken by someone else or does it take its own measurements. How are the corrections applied? Is there a manual online? Not sure how we got off the Ember topic but what the heck, it is interesting.
As for listening and enjoying music I am of the same mind. I didn't change my last system for over 20 years. Just listened to tons of great music. But I am overhauling it now, I replaced my speakers, turntable, and now headphone amp/phones. Remember, for 20 years I listened to a Creek/Sennheiser system that I now realize was far from optimum, LOL. In my mind I just didn't care for headphones. But recently I find them quite captivating. Crazy to think how much less a good headphone system can cost than my speaker system. For a music lover or an audiophile on a budget this is a great way to go.

Maybe I will build a Kameleon. I was excited to build the EmberII but due to availability issues I got a built one for a great price instead. I like soldering, I'm a craftsman I like building things.

Kameleon 2 info is hereoriginal Kameleon thread Kameleon documentation (still subject to updates) Garage 1217 is going to sell an add-on that accepts Kameleon modules ... someday... possibly also as a kit. Hopefully before the end of this year. This only has to do with the Ember because the G1217 filter module will be sold by G1217 (in due time) and can be used with all G1217 (and other) amps.

The Kameleon filters are spot on Husafreak. Reason being that Frans has imo, correctly identified frequencies that are off, so it's nothing like an estimation. That's why the filters are so good.
The Hd650 on a Kameleon is stupendous. It really is. In fact, taking the Kameleon away kind of highlighted the HD650 'real' problems without the Kameleon to me and what is referred to as a veil was the least of its problems. It's kind of like it's 'blown its nose' and everything is just more in proportion. Going back to a 'normal' HD650 was hard for me and I stopped using it as a result.
The funny part is that it's the bass that seems way different. Deeper but less bloat. Because of that, the treble sings though much more easily without really being touched.
The idea makes a lot of sense as well. It really gets the most out of the headphone that you choose to use by providing a good amount of power and eq'ing for a flatter response.

Cool. I may try to turn my HD600 into an HD650 on Eby. I've always wanted the fuller bass the 650 is known for over the 600 leaner signature. I find that the bass and drums really do a lot to make listening to music more fun for me. All the while disliking subs almost every time I hear them! Go figure. I am seeing some love for the 6n6p tube Jeremy recommended  But again which Jan Phillips tube are you using? Is there a specification or model number for it? |

Just a Jan Philips.. Marked Jan 6922
Cheap as chips. It would make you think more about how much you'd really want to pay for tubes!!!

Thanks! I haven't bought any tubes online yet but I thought $20 for the tube from Jeremy was OK. I imagine like anything the prices could be all over the place.

The availability has a bearing on prices but you can rest easy that Jeremy won't be doing any ripping off. There are some out there on Ebay who are a bit naughty, selling old tubes pulled from gear as nos. You have to watch out for that.

Does anybody know if ECC31/6N7G/6AS7 tubes are compatible with G1217 amps?
They appear to be dual triodes with an amplification factor similar to 6DJ8 tubes.
There is a special 6N7G to 6SN7 adapter available to buy but would ECC31 tubes possibly be compatible with existing 6SN7 to 6DJ8 adapters, like Jeremy's?
I know there have been negative comments about tube rolling recently on this thread but I personally find different tubes alter the sound enough to make 'informed' tube rolling worthwhile.
Thanks for any info.
EDIT: I have now found out the 6AS7 is a non starter with a heater current of over 2A!.

Not negative Howard. Just warning of the dangers of it becoming an expensive habit!! Chasing your own tail kind of thing.

It took me almost 4 month of 'information' (and a lot of rubbing in my face ;-) ) to decide to buy a pair of Visseaux 6J5. I don't regret a single penny spent, but I am somewhat done with tube rolling :-)
