I could certainly look into it. There are, however, a few different versions which differ in treble peak. The Edition, the pro, the earlier model and later model.
They will require some subbass boost and removal of the treble peak. Otherwise these are pretty linear. Don't have one to measure though so would have to depend on other measurements.
I need to make a lot of filters anyway and thought this may be a good idea for the coming months (designing filters that is)

Just bought two filters already and a Kameleon unit from Jeremy. A DT880 Filter will be a nice addition.
thanks Frans

Which DT880 exactly ?
The 32, 250 or 600 Ohm version ? The older one, the newer one ? The 'edition' or the 'pro' version.
I designed a DT880 filter already for the later 250 Ohm Pro version. It is not yet in the manual but could send Jeremy the values. Made a filter for the HD660S as well.
Need to make a few more... will add these in the manual all at once but this will take a while.

Is there any prospect of a Kameleon being made with balanced connections? I would be very interested in one of these if it became available.

Sorry for the late reply..
No balanced version will be available. There is too little demand for it and would require XLR connectors as well which would mean a lot bigger PCB. Certainly if the input would also have to accomodate for balanced.
Also those demanding truly balanced would not be possible as the filter would need to be doubled and need really close tolerances in parts.

Frans are you planning to order more of those boards? Yes, I have 14 boards available. Some slight changes to the layout and component choices in the power supply circuit. A wider range of DCDC converters can now be used. Z1 is now shown correctly on the PCB. No changes in the audio path nor in the general layout. Also a new build manual has been made. 1 built prototype PCB will be up for sale when it is done. Just the PCB + components, fully tested so without an enclosure.

Hi Frans, I would like to buy it if it is not already sold. Since we got the second kid, I have virtually zero time to build these things. I am still trying to figure out how to build the case for the Kameleon amp... Just let me know!

Will reserve it for you. It is just a PCB with components on it. Some parts still have to mounted and am waiting on these parts (have been ordered) NO enclosure.
