I'd say there were fundamental issues in music reproduction which need to be got right (specifically within the design/implementation of the transducers) before worrying about the presentational niceties that omnidirectivity appears to addr...

A nice 30 minute b/w film about the production of miniature valves by Mullard in Blackburn, England.http://www.techtubevalves.com/about_us/film_reels.phpIt would seem that some of the former employees at that site are to start producing some audio va...

Are you absolutely sure that the headshell mass loading you use has not had an effect on the life of this cartridge?I have my reasons for asking but the explanation is too convoluted to write at this moment!...

There are times when a photograph, however well taken, is not enough. The contemporary British artist Lucien Freud paints portraits that tell more about the scene and the subject than perhaps a photograph ever could. This interpretation somehow...

I think it is Wiremold part number L10320. At least it used to be.
It has no filters, no switch contacts, indicator lights or passive protection devices and uses hospital grade outlets....

[quote user="be"]Gregm, you wrote: "Yet, the best result -- i.e. most homogeneous sonically -- came from the thinner wires in interconnects."Did you use silver wire for your comparison?[/quote]I used copper in my example above. Later on, I received r...
|
|
[quote user="be"]I recognise your observations about the Ag vs. Cu sound, but instead of mixing the two materials I think it is better to change the diameter.I experienced 0.5 mm silver wire to be too thin soundvice, have you tried 1.0 mm or even mor...

...Why not also try a paralleled "solid-core" (single wire per leg) cable. You can twist the paralleled wires if you wish. Proceed carefully, using about 1-1 ½" between the wires. Try silver on the return first...Just as an experiment; as you note, y...

[quote]“The
Tenors bring a remarkable top-to-bottom continuity, which I've often
called the Kharma effect (the speaker, not the moral law of cause and

While the question was somewhat facetious there was supposed to be a serious point behind it. I experience a similar 'effect' with a linestage I sometimes use. It is quite easy to hear what this stage contributes and initially it is too differe...

Perhaps if you build another phono corrector you could play your TT through that, then through the inverse RIAA then through the EoL corrector then the linestage & power amps etc.
Will you be listening to all of your line level sources via ...

Isn't 330 ohms a little low as a plate load for an ECC83/12AX7 to be running into? 330K ohms perhaps?You often ask what is wrong with a given speaker installation, I thought you might be doing the same here. Keeping us on our toes :)...

Thank you for the description. How they are sealed is what I am most curious about. I've tried a few different techniques to seal fluid in the tubes during my cable experiments. Does it look like they simply injected a clear silicone, terminated to R...
|

Interesting, at this stage it's early in your testing so I am mostly interested in how they are terminated. Can you provide a picture of how the fluid tubes are sealed and the cable terminated to RCA?

[quote user="Romy the Cat"] Tim, it is all very interesting and I would like to learn about the Proteus’ inner wire juts for a sake of general education on the subject. However, I would not go for a duplication of what Purist did. Doing it you will s...

In the past you've referred to current loading in the context of cable length. I recently experienced this when I experimented with moving my amps. I needed to increase the IC length from 1 meter to 3 meters. The only IC I had at that length was an o...

Did you see this piece Paul?http://www.tnt-audio.com/sorgenti/vta_e.htmlI'm not sure what to make of it. We certainly don't seem to suffer with the issues of poor mains to the same degree over here and I found that I can set up my cartridge so that i...

The arm pictured above may be made by Rossner & Sohn (as is the turntable) but is definitely a good deal longer than 12". One wonders when the benefits of better geometry become outweighed by the reduction in stiffness/structural integ...

Paul -- I used 1st order & bandpass on the Beyma. I think that 2nd on the Lowther would have been better.I set out to try and extend one "way" from the end of a wide-range drive unit, downwards. This I found to be well nigh impossible -- perhaps ...
|
|
and not very encouraging. The set up was as follows: a Lowther ex4 playing from ~12k down in a big ~100Hz tratrix. A Murata up on top, and a 15" Beyma on the bottom. The Beyma is in an Onken so the results may not be fully indicative of performance i...

...we'll have to compromise somewhere. So, since it isn't the spkr's range, then it must be the amplifier. Forget the ML's 18W. We must have ~38-40, so let's say our machine is using a 45 / 211 / 610 /g70 type of tube.Also I don't suggest we conclude...

[quote user="Romy the Cat"]...it is difficult to design an objectionably performing powerful full-range SET without considering speaker, particularly the moment of LF section damping. It is not always the case the MF, HF and LF would require the same...

It doesn't seem prudent to look at the speaker without considering the amplifier at all. We would be designing a speaker that would work with a theoretical amp -- but not one that's available.I propose the following:Characteristics of many commercial...
