[quote user="Brian Clark"] Whereas I do. deParavicini's worked on designs in Japan over several years and became familiar with the research going on there in the Seventies which culminated in identifying the HD decay-spectrum as a key indicator...

I was searching for an answer why squire wave is so screwed and I was advised by the site’s visitors that it is due to HF restriction of my channel. My HF response does look too low to me – the 23kHz; with all my ultra low capacitance magnetic I ...

There are few more observations I would like to share after listening
my new IB over this weekend.
The midbass. The midbass channel that is handled by a single
Vitavox 15 driver with use of my new IB became if not more propitiate but at

Spent today a whole day moving the boxes, do some measurements,
fighting with REW interface, thinking, some listening… Found some bugs in the
system that I think screwed my initial feeling. The bugs were mostly by Thomas

[quote user="ulf"] Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than we desired. [/quote]

[quote user="Romy the Cat"]So, if the Ultimate MF Compression Driver is used from 1000-1500Hz then why shall it be able to play 500Hz? The answer is: he harmonic reserve – the driver that will be suited for 500Hz will have larger cone and softer sust...

Recently there was probably nothing as low in audio as the BS surrounded Kharma loudspeakers. Each single step Kharma takes is further and further in-depth Kharma into the realm of bogusness. It is not that I find that “Kharma the Manufacturer” or “K...

OK. After a few days of self-education and harassment of various technical people I got what I need – the truth and the reasons why both of my Sansuis TU-X1 sounded so honorable from 75R FM input and so much better from FA-7 input. Below I will...

Martinshorn , that for feedback, as I always preach:
the bad result during audio show does not mean anything, only good results
count. You see, there are zillion reason why during the show the sound might be
horrible. The inadequacy of the people ...

Spent great time and with happy with result. Not the results
are so spectacularly good but the playback is back to be operational that I was
missing for a while.
Starting with films. The damn OPPO has not enough output for
my Milq. I decided to...

Hi,Given that Romy already let the proverbial Cat out of the Bag (pun intended) I think I may have to make good here....

An Audio Amplifier Design Philosophy

I became interested in audio at a very young age because I liked music, but was too uncoordinated to be able to p...

This weekend wife told me that I should not do nothing else
but to fix my playback and this was exactly what I wanted to do. Yesterday I took
good 14 hours to play with it, moving boxes, trying to find a good

the table ran slow was with the thread belt. Speed is very constant with
