[quote user="drdna"] If you were using, for example, the Kron KR 2A3, you would not be commenting on the sluggish liquid sounds, and it would be very much more competitive with the Melquiades I am sure of it. Adrian[/quote]I doubt swapping...

[quote user="drdna"] So what we did not see was the dynamic response of the Avicenna in maintaining its perfect sine wave against a variable dynamic load. I guess this is where the improvements can be made.[/quote] I am sure what it means as I have n...

|
[quote user="drdna"]From my own experience, every change that has stayed permanently in my system, at first seems soft and sort of boring. I am inside always a little disappointed when I first hear these changes, because they seems so neutral and une...
|
|
[quote user="drdna"]Very interesting, it is certainly worth a try. Do you have the information on frequency response, impedence, etc? [/quote]http://website.lineone.net/~empson/S3.html...

|
[quote user="drdna"]Experimenting with the new 2A3 tubes has been a very interesting experience. It has given me insight into more specifically exactly what I am looking for in the stereo sounds, which I associate with the Sound.
The most we can as...

[quote user="drdna"]But I am worried what all my friends and neighbors will say if get up and start to dance to Lutoslowski![/quote]Grab one of your kids and do it. Looks perfectly normal then! :D...

[quote user="drdna"]Hey this looks vaguely familiar.http://www.dagogo.com/Spotlight/AcapellaTriolon-Crowder.html[/quote] Actually I read this “review” of the “Acapella Triolon Excalibur four-piece horn loudspeaker system”. Well, not the entire review...
|
|
[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"] Point source installations have a distinct character. [/quote] I do not think that the point source installations have a distinct character because they are point source. They have distinct character because they are always shitt...

Dear Drdna, I red with interest about your experience in cables would you please give us more info. As I 'm sure many audiophiles are tired of spending $10000000000for cables which actual material cost are $0.00000000000001!Armen...

[quote user="drdna"]AND I just checked on multiple browser platforms and still could not see and EDIT button or a way to modify my posts.[/quote] OK, it must work now. You need to login into the site for each browser and I set login status with cooki...
|
|
[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...
|
|
[quote user="drdna"] Yes, we are saying the same thing. The problem as I have found it is that transparency is easily recognized and so there is a tendency for audiophiles to focus on this when they try to improve their systems, and this can ma...
|
|
[quote user="drdna"] Fundamentally I think the injection channel and layered sound are different things. The injection channel is designed simply to compensate for the timbral shortcomings of a particular driver. However, because of lobin...
|
|
[quote user="drdna"] 1. The perfect sinusoid unmasks the compensation of the system for imperfect power -- it is like when the car stereo comes on when you start the car, way too loud, because there is no road noise to adjust for any more. The sound ...
|
|
[quote user="drdna"] The first key would be
that the digital reproduction be of a high enough sample rate to fall
below the threshold of perception. The scond would be, in my mind, that
the process of reproduction not create a new structure, but r...
|
|
[quote user="drdna"] It is not exactly correct. There is 60 Hz hum eliminated by lifting the ground to the amplifiers. The neutral is connected to the ground prong and chassis in the amps, so I assume it is setting up a loop. However, there is a seco...
|
|
[quote user="drdna"] Romy, don't be silly. You are trying to tell me you cannot hear vertical position? You cannot tell if the cat meows, if it is on the ground or the ceiling. Of course you can; do not be ridiculous. [/quote]
Nope, I of course do...
|
|
[quote user="drdna"] It will be a little project to modify the amplifier, but it may be educational. To optimize the Moondog circuit for the NOS 2A3 tubes, so they will give their best, I plan to buy a new OPT with primary impedance around 3.5-4K. [/...
|
|
[quote user="drdna"] So, my thought was that below 35 hz, there are many ways of thinking about amplification. Some might say SS amplification is helpful due to power demands of horn loaded 18" woofers. To use 6C33 might be a trade off but I do not k...
|
|
[quote user="drdna"] As I said before, the perception of the audiophile imaging and soundstage is really gone. [/quote] I think you might revise your view about imaging in future. No one cares about soundstage but with imaging it is a bit tricky. One...
|
|
[quote user="beachbum"]Did so cause i was still using my BPT for everything but my amps. I had a hum and high pitch buzz from my speakers. Replacing the power cord feeding my amps was the cure.[/quote]There was some mild 60 cycle hum which was elimin...
|
|
[quote user="drdna"] First of all, this not an attack on NOS tubes …[/quote]
A very strange introduction. Since when people post at this site feel a need to ask apologies for attack or not attack anything? Also, where this phase “attack” eve...
|
|
[quote user="drdna"]This sounds like an interesting idea, especially since it eliminates the RIAA components. Eliminating components is usually a good thing. However, at the "entry level" price of $8,000, I don't think I will be buying one any time s...
|
|
[quote user="drdna"] 3. When the PP2000 is plugged in, the neutral AC connection adds an additional ground reference. [/quote] Adrian, if you make such an assumption than it was why I advised you do not plug all your components into PP20000 but to pl...
|
|
[quote user="drdna"]Let me see if I can edit this entry after I post it.[/quote]Nope. I only see profile, print, e-mail, quote, reply. Is there supposed to be an "Edit" button that shows up, or is there some secret special way I don't know about to ...
|
|
[quote user="drdna"]What is revealing is that the system functions poorly with recordings with a lot of reverb. This is what one would expect of course, given the setup. Probably the best recordings to play on such as system would be the old Three Bl...
|
|
[quote user="drdna"]I noticed this problem begin to occur yesterday, so possibly it is related to the changes made to correct the editing issue. The text on the forums pages now overlaps and runs off the page. The problem occurs with the browsers Fir...

PP, before you question my assumptions, have you actually read the user accounts of your products in this long thread? I think there may be 1 account of a customer who did not want to return a unit for some reason or another, except, later, he did w...
|
|
[quote user="drdna"]Do not buy from this company. They took my money with no intention to ever deliver a unit to me. If you find a unit on the shelf in a store and it is functioning, buy that unit and take it home. Don't give Purepower your money up ...
