[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"] 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"] You had described the Melquiades as a "reality Reconstruction" amplifier. In my mind, I have always associated the unpredictable quality you describe with a "closer to reality" sound in my system. [/quote]
Well, I might ...
|
|
[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"] However, there is something to be said for the certain magic that can sometimes happen with a particular device. The unpredictable transients and color shades add a sense of alive-ness that seems separate from the standard charac...

[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"]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"] 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...

[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"]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...

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"]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"] 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"] 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"] 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 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"] 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"] 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"]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"]As I had been looking at all these tubes I began to also inspect their interior construction. This will amuse you: one thing I would do is to hold the tube right up to my ear so the glass would be touching and thus mostly damped. ...
|
|
[quote user="drdna"]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rugged, overbuilt. There is no comparison between this tube and all other 2A3's, and I tried many of them. The sound is more dynamic, the...
|
|
[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"] The VERY INTERESTING idea is that the introduction of noise as a dithering element for the analog signal (for our brain to decode) can be helpful in increasing the retrieval of information vital to conveying the Sound. [/quote] T...
|
|
[quote user="drdna"]Is it possible that a simple experiment can be done with cassette players and the Dolby filter since this equalization affects compression for example? Adrian[/quote]If you are referring to the "soundstage" quality of such playbac...
|
|
[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...

I listened to Purepower 3000 we finally got it in iran.it is wonderful , new level of dynamics , far better than direct utility.I have a question about pp3000 if you had it in a ultra transparent system.our system is not ultimate in transparency and ...

[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"] 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...

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...
