Well, You really need to figure out what you want out of your speakers. There are some questions I would ask myself if I were in your position:1. You can eliminate a lot of speakers based on their size, since they should be mat...

[quote user="morricab"] I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty resona...

Thanks for all the suggestions. As it happens, there were no exhibitors at the Flemings Hotel this year. But I did pop into the Stax stall before listening to anything else.In general, I was pretty disappointed with what I heard. Most of the ‘convent...

Only yesterday I started to get some interesting results after tuning the UK crossovers. But still not near to the sound I'm getting from my electrostatic headphone setup. I assume my Dannoy setup is quite compromised: one of ...

Romy does explain things correctly, in his own way of course.Modern electrical field theory has it that the electrical field attached to a cable, stops progressing along the cable for every vector change in the field. Not exactly a digital event but ...

...but it will take me N-years and I'm in EU :)I could make some preliminary steps this Easter, talk to my winders about transformers etc.I'm for sure missing the FW and out put cores (AMCC800A will not support 120H at 300mA, low DCR), but getting ma...

This is something I've been chewing on for quite some time and finally decidedto make it happen: a serious Stax headphone amplifier.I hope I can use this space as a sort of a blog-report on the progress...if not feel free to remove. I've been "forced...

The EV 350 cones are still available form many sources, they are $25 per cone. There are some other phenolic domes for 1” driver, or smaller. I do not know anyone who does 3”-4” phenolic domes that would make them suitable for MF drivers.
As far as ...

[quote user="tuga"]If you have a midrange driver you can try that for yourself.[/quote]In this case the lack of "full-range" audio is so glaring it overwhelms any advantage of the point source, I think.

Cody, this is a kinder, gentler GSC than in earlier times, but FYI your ingenuous intro is just the sort that used to draw heavy fire here. The only reason I have responded at all is because you got me thinking about what I do and don't like about el...

In one idealistic configuration I envisaged for myself, for a situation where cost and practicality no object, the basic room shape was pentagonal, with the facets ot the pentagon curved inwards to eliminate parallel reflecting surfaces and simultane...

[quote user="Jorge"]I tend to think that we are not copying Romy, but more that he has generated a school of thought on audio and yes horns speakers also.I too have a system following some of the Macondo Axioms, but have used all diferent drivers.As ...

Just some additional thoughts on the new generation of 2A3 tubes. The only ones I would seriously consider are the Kron Enterprises, the Sophia Electric, and the Emission Labs tubes. If I did not hear these side by side over an extended period of ti...

After years of using the Expressive Technologies SU-1 and SU-2 step up transformers I come across to a fact this morning that the Expressive was reviewed by Robert Harley in June, 1992. I read the Expressive’s preamp review but I never seen this one....

[quote user="Paul S"]N-Set, why would you disconnect from the house neutral, unless you are using battery power??? This "neutral" is the "ground" leg of your circuit! The house neutral wire is typically white, and the house ground wire is typically g...

Hi Romy,I've seen and heard many products in which an aspect of the design is interesting, even thought provoking but where that idea's implementation is poorly achieved. It doesn't mean that one can't learn anything from the product even if it's onl...

well the way not to create problems is have a giant electrostatic panel.
starting from that point we create problems ...

Most here are probably familiar with the fact that A/B "blind tests" were popular in the early days of "audio", where listeners seemingly could not distinguish between live sounds and electronic "counterparts" issuing from behind a curtain. Today we...

Hi,[quote user="Romy the Cat"] After some experiments and still being dissatisfied with the HF I ended up consulting with Dima. He spread me a theory according to which the HF was killed by my coupling Silver Mica cap. All my arguments that sil...

DHT amps can sound good or maybe charming is the right word, but I believe it is due to an error related to the concept of oops described elsewhere on this site.
This is the result of the filaments resonating and contributing with a sense of life an...
