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...

Measure the ceramic ball that is in the bearing and order the closest size avaiulable. I believe it was 0.25" but it has been a while since I rebuilt my bearing.Jam...

It is my long observation that PP amps are very bad for driver with Alnico driver, they usually eat all details. The ceramic drivers however, that are ordinary are horrible for HF, are very nicely work with PP amps…[/quo...

I have had similar impressions to other speakers using these drivers. For example I found the top of the line Avalon Eidolon diamond to be similarly colorless and lifeless. Also a pair of Vaic speakers (designed by the guy from Lumenwhite...

I have experimented with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that ceramic drivers with SETs that I have heard being suboptimal, but after a year of DSEP, at least for my use case, I am quite content. I cannot explain it ...

Interesting, in my amp the whiteness of the 6C33C sockets never bothered me. I think if it bother you then you might located the socket slightly below the top panel, this way you will not see them so easer. If you use ceramic base then ceramic is pai...

[quote user="el`Ol"] Hello Romy, have you searched for explainations for these observations? Are there others who made the same observations and tried to explain them? Does the damping factor play a role?From my limited experience I can say that ...

I would not call them “bad”. They use very different magnets and meant to be used with higher power (with all negative consequences). You see the ceramic magnets are more or less OK for LF application but when a driver goes up and hits upper midrange...

Hi Angelo,Thanks for the kind words about our website.Hmmmm... it is really difficult to make the sound of the Avalon speakers have no depth or imaging (I presume you are referring to the Opus or Eidolon? Their small Symbol speakers do indeed sound a...

I am not a huge fun of S3 for MF use as the ceramic magnet is less interesting then alnico magnet for HF applications. For the low mid, or as I call it the Fundamental Channels the HF problem that ceramic has do not manifest themselves. My Fundamenta...

[quote user="CO"] May i ask if you have ever played with the Le Cleach flares and how you find them?They were created to reduce reflections directly back into the horn. Only problem is they are very large because of this.... [/quote]
Nope. I never h...

Axel:One wonders how much one must pay to get it right from the start...Actually, the "sagging" cantilever is not peculiar to the Jubilee or the Windfeld, but it has been a long-standing problem for Ortofon on a number of their more expensive cartrid...

Yes Paul,DSEP is planned. Actually I have already experimented with it only with the 12" Fane neodymium midwoofer that covers 80-1K and using 1 cap for the low pass filter. I really like what it does. I am comparing how it works with ceramic and neod...

Very interesting… Earl Geddes just posted his thoughts for the Morons at the AA. I do not know is he was inspired by my post of by the completely foolish nose that the AA’s idiots razed around the Cogent’s Steve and Rich experiments but still – it wa...

Gordan, I think you are missing the accent of what I meant to say. The Class A or not is not important for compression drivers and the S3 in particularly. I mean it is important and it much be ONLY class A but I do not see any SS amps switching in cl...
