[quote user="drdna"] I know all the compromises involved with the EdgarHorns, I have heard them when I visited Bruce Edgar in Gardena, and they were pretty good compared to most of what is out there. I realized that I would likely never be able...

[quote user="drdna"] 1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which is based initially on a single-driver type backloaded horn. To me this suggested that the seller was seeking the benefit...
|
|
[quote user="drdna"] Now I have had the EdgarHorns in my system for a number of weeks and have been moving them around the room and moving things in the room around to make them sound their best. [/quote]
If you are not familiar with horns then it u...

Dear Romy, What is your opinion about silver cables drdna suggested (http://www.laventure.net/tourist/cables.htm)Armen...
|
|
[quote user="drdna"] You are correct, though I believe the subwoofer covers only below 40 hz. [/quote] So??? [quote user="drdna"] This is coming from the same person who has built a 6-channel DSET? Anyway, it was more a thought about optimizing the o...
|
|
Dear drdna, would you please give us some info about your cables, as I'm tired of seeing $10000000000000 cables which in fact the cost of material is $0.00000000001!Armen...

[quote user="drdna"]Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned. Looking at the phase of the individual drivers and listening to each of them individually revealed that ...

Drdna ...well i have already listen to all the speakers in my area....so if i want to listen more stuff i have to travel....and i haven't unilimited founds....

|
[quote user="drdna"] This implies that it is up to the stereo equipment to determine the perception and perhaps there can be one ideal stereo system. While it is consistent with what is observed, it means that there is no human variation in listening...
|
|
[quote user="drdna"]1. This may simply be a symptom of electricity variability. I would listen for a few days and see if it improves. [/quote]
Do you mean that electricity affects the sound of one cartridge but not another? I doubt that, parti...
|
|
[quote user="drdna"] The Decca London Reference appears ideal. I am probably going to buy one of these. Romy, you are free to borrow it if you wish to listen to it; just do not break it. [/quote]
Possible it is a good cartridge, I do not...
|
|
[quote user="drdna"] Not that the sound is bad, but my technique must be bad. Because sometimes during the day the sound will get really particularly bad, even to the point that it sounds like clouds are passing by over the music, if you unders...
|
|
[quote user="drdna"] And the explorations that led you from the original Melquiades to this current set-up are well-documented over a period on months. Still, it might be instructive (to me at least) to hear concisely stated your dissatisfactio...
|
|
[quote user="drdna"] It is a very old idea to say that higher power is required for good bass response. I do not think you will get any argument from anyone that increased power makes finding solutions to achieve a good bass response easier. [/quote]...
|
|
[quote user="drdna"] Yes, I assume the problem was the ground path through neutral, either because of a high impedance or because of an interaction of the PP2000 with the isolation transformer. [/quote]
Ah, you have also an isolation transformer sit...
|
|
[quote user="drdna"] First, I do not accept the hypothesis. We must confirm that the Avicenna was working correctly when no impact on the sound was made. It has happened before that a simple mistake in observation led to a faulty hypothesis. It must ...
|
|
[quote user="drdna"] No, when the PP2000 is totally unplugged from the wall (and hence the neutral path which is also grounded is removed), the hum disappears. Then the whole stereo is functioning like some giant battery operated device. This is odd,...
|
|
[quote user="drdna"] Try a simple experiment. Connect only one driver at a time. Listen only to the ribbon tweeters. Now listen only to the woofers. Etc. Can you distinguish different heights for the image? [/quote] Of cause I can. [quote user="drdna...
|
|
[quote user="drdna"]The idea of 360 degree radiation of sound has great intuitive appeal to me since I feel the best recordings are done with two omnidirectional microphones. The most precise reproduction of the musical event would seem to be: ...

|
|
[quote user="drdna"]If it was not clear from my oblique comments before, I agree with what all have said, DAC1 seems to be techinically more correct but at the expense of some information loss. DAC2, which I prefer, has more distortions but als...
|
|
[quote user="drdna"]It is funny since they are identical digitally recorded tracks you would think they are the same. I would very much be interested to know if the binary code is identical or not for the two tracks. [/quote]Drdna,Do not even s...
|
|
[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="drdna"]But how can you make the Melquiades as a DHT amplifier? I do not see it. [/quote]
To make Melquiades as DHT is very simple juts use DHT output tube. However, if DHT idea does make sense then I think the diver shell be DHT as well...
|
|
[quote user="drdna"] It has the Magnequest DS-025 OPT, connected to the 16 ohm tap. [/quote]
So, it is 2.5K primary and you drive 8R speaker with 16R tap. That makes the 2A3 loaded in your case with 1750R. I think it is necessary to know in order to...
|
|
[quote user="drdna"] Would you then suggest that this approach demands the DSET approach to succeed? [/quote]
The DSET resolves all problems with SET amplification; it is not surprise that Sakuma went there. BTW, my familiarity with Sakuma’s DSET wa...
|
|
[quote user="drdna"]Maybe I don't know what DPOLS is, as suggested by others in this forum. All I know is that I can spend a lot of time fiddling with the exact location of the speakers, the sepcific 3 dimensional alignment of the two sets of d...
|
|
[quote user="drdna"]Romy, I think you are asking if I have the Edgar subwoofers also. Yes, I do, like giant woodgrain refrigerator in the living room. So I do get some bass response. [/quote]
Yes, I was asking about the Edgar refrigerato...
|
|
I ask myself wheter someone who belongs to drdna´s group 2 has to belong to it in optics as well. I still have my Sony Trinitron TV and I find it sad that Agfa positive films and Ilford positive papers are no longer available. On the other hand, is i...
|
|
[quote user="drdna"] Well, I think the short answer is yes.
What the people over at Technical Support have told me is that this is due to the power supply design of the amplifiers that are being driven by the PP2000 and that it seems to be cha...
