This line is corrected in post 1379. And obviously in the skr file from post 1342, as they appear identical.

I did not remember if I had corrected it. Jimmy discovered it and told me in private.

Correction: The latest version is adjusted so that the file created by MKROM has the maximum values of impulsive response. Displaying one by one the binary result in the skr file so that it does not saturate that impulsive response. So take advantage of the maximum precision in the coefficients. And for the DAC not to saturate, it is recommended to play the music at -2 or -3 dB of volume. Especially the very compressed music (all the today music) can saturate and sound very hard.

Is this a port of the old 2k filters?.... It's good Soren clarified that 2k filters can be used on the new firmware...

Just read everything from page 50, together with the posts at the beginning I read previously, and I now realize how much Paul has contributed...

Sad that there's no way to get in touch with him. It may be close to trivial for him to make new 4k filters based on the same principles as the party pak. Read a bit about how Chord Dave has 164,000 taps... Wonder why Soren didn't use better FPGA chips in his recent products... We have LX16, Dave is LX75, top of the line is LX150. The number of logic cells is proportional to the product number.


Very impressive that Soren managed to upgrade the product family to 4k taps though...

It is not a port. And it's good for 1.19 of course as SŲren describes.

Well you know you need to present us with the technical specs even though I do trust your ears and much more than my own... Do take it as a compliment

So you need the technical spec in order to evaluate it?

Trusting someone else ears is not advisable.

Thatís somewhat true yes. But itís complicated

If we donít have the data there isnít much point to begin with I think... my listening skills arenít that good anyway.

Although it might be interesting to find out why the balance on Soren 4K filters are off by so much. Even the 1.19 has a lot more bass, let alone the distorting 1.20. I doubt Soren messed with the freq response

To test the freq or impulse response is the easiest task,
