Romy ThanksI had 6 pure power (230v version) since 2017 and now i have 4 pure power , the first pp3000 was faulty and it has the same problem that some users reported here (GSC) , the output frequency spectrum of first PP3000 had some extra harmonics...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

I would agree that the Lowther is not hard to beat but the question is where and in whose mind does this competition exist? Is the Lowther, Manger, or other full range single driver in competition with different multi-driver approaches, other single ...

It is nice to see you around, Jim.
A few comments. C1 in my phonostage is .28uF. The higher values were a proposal of Anagnostopoulos. I understand what he is coming form and yes my output stage of power amps will be able to handle the ULF stress. I...

The most important in audio is a state of realization and obtaining this state is a matter of time I am afraid. Let pretend that tomorrow I will build/buy some kind of speaker that would do the perfect ULF channel ...

Romy,I actually had one of those horns, as I wrote in the first post. Edgar 80hz straight horn. I sold it long ago because I did not like the sound, no matter what amps I tried it with. The problem was, to me it sounded muddy, no matter what I tried,...

Antonio,You should expect to hear just the music. In explaining the effect of this process in words, I am in a simmilar position to Romy with his Melquiades amplifiers.Most speakers sound just fine, to those who are used to them. We have, in our sens...

[quote user="haralanov"] My comment may look too simplistic, but it is not. The frequency response is not self contained entity, because it shows the energy balance of the Sound. So you can have flat energy balance of good Sound and you can have ...

Thanks, jtavan.
It was educational. I made some first steps already. I made a slow 233MHz (and presumable it would have lower noise with lower speed) machine with no fans, and a large passive radiator on SPU. Formatted it and loaded Win2K Pro St4. S...

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...

C, I very much agree about the benefits of spherical needle, partially on the older records and out of condition records, and this is one of the reasons why people have multiple arms on TTs. Yes, in many cases the spherical stylus “tracks better” 9mo...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

[quote user="haralanov"] It is certainly very very important, but how many systems you have listened where you can not be able to recognize the HFs as disconnected part of the sound? I just wanted to ask if you have ever heard a system, where the...

OK, this turns out not to be a no-brainer. These caps are definitely quieter than anything I've used to date. At times, there is a sense that "something is missing", but then the "missing" frequency pops up loud and clear, apropos the music (as oppo...

This is a very interesting post Romy; thanks for putting this together and providing sample files. Looks like bad electricity is stuffing pillows into brass and covering strings with shellac. Or is it?* On the first chart I thought it would be intere...

Romy,reading your post a most recent listing consequence comes to mind, that I could also not quite place. I worked on a my cross-over, the RCL of my mid-range driver, and had a by-pass cap of 1uF connected over the 2nd base cap of 47uF on the one ch...

I had a Walker Proscenium turntable with various cartridges. About twenty years ago I converted all my vinyl to 24/96 files and have never looked back. As far as dsp processing, the Trinnov altitude does a superb job of either recreating the hall sou...
