[quote user="drdna"]After all some people proclaim there is no difference with different wires; clearly not true. BUT, it is a difference that is important to only some people. Is it possible Romy cannot hear the sonic problems that are solved by the...

[quote user="drdna"]There have been a lot of discussions about this before, but one must always take this sort of logic with a grain of salt. Musicians are trained to hear certain things in music and simply hear differently than non-musicians.&...

[quote user="drdna"] In my mind it is fairly straightforward: stereo = two channels. Two channels = two point sources. Of course this is only one possibility. However, critical to what I am saying is converse to your statement: instead I feel there c...

[quote user="Romy the Cat"][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 touchi...

[quote user="drdna"] Oh no, after all, you haven't even said anything about how it sounds. I suspect that both the Avicenna and the PP2000 will be equally great. However, since you mentioned Dima was thinking of making this into a commercial product ...

|
[quote user="Romy the Cat"][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 ...

[quote user="drdna"]Well, I'll stick my neck out and tell you what I think. I would say that it sounds right now that you have a kind of undefined idea of how you understand the sounds of audio reproduction. Sort of on the level that you ...

Dear drdna,
Thanks a lot for reply and helpful advises actually this is the only site I read these days. That problem with carpet was not low frequencies alone, surprisingly it did a lot more damage. Will you explain more about egg crate, my speaker...

[quote user="drdna"]Hi! I have got these 6E6P tubes from Georgia (in the former USSR, not the home of sweet potato pie). I have removed them all from their protective glass packaging, but I am unsure of how next to hook them up.[/quote]BT...

[quote user="drdna"] While it is true that changes are constantly being made probably from unit to unit in production at APS, the major design change occurred with the adoption of Class D circuitry in the PP Plus series.I suspect that the problems ar...

Romy and drnda,
When you speak of the "Chinese 2A3" which one do you mean? Romy, if you have the Shuguang 2A3C then I understand why you find it better than the Sovtek, no argument there! drdna, the Shuguang is a little more extended on top than t...
|
|
[quote user="drdna"] I am quite sure it is a ground issue, as it is noise coming from the loudspeakers regardless of source or volume. Lifting the grounds on the amplifiers… eliminates the problem. [/quote] If it so them there is no need to contact t...
|
|
[quote user="drdna"] So it would require a new OPT to be made with around 3.5-4K primary impedance. The power the amplifier puts out is already far too much. I always have the volume dial around 1-2, so this will be okay. I don't have such an OPT on ...
|
|
[quote user="drdna"] How about using the 6C33C for the low midrange-woofer, the 2A3 for the upper midrange, and the 45 for the tweeter? I suspect if each circuit can be optimized, that they can do their best within each frequency range. [/quote] Hm…....

[quote user="drdna"]Gosh,A personal visit from Richard! I'd love to hear more, Romy. Richard has sent me so many e-mails promising to send me my PP3000+ replacement unit from the next batch of units he makes, but of course he says that every time, an...

[quote user="drdna"]However, there is no comparison to the expensive tubes from Kron, Sophia, and Emission Labs. These are all in a separate category. These produce a very different sound. It is like this: on the old black and white TV sets, there we...

[quote user="drdna"]Ha! Criminals is going a bit too far, unless you want to call all the audiophile companies criminals. I am not saying that is not the case, but the behavior of PurePower is not different from many other audiophile companies or man...

[quote user="drdna"]After many unanswered e-mails, I got word from APS today, who said they have had a few customers with similar issues and that it seems to be system dependent. However, they also said that they were working on a way to fix this tha...

Well, I did not mean to express any specific attitude to Bottlehead people - the only experience I had to them was a few years ago visiting their meeting right here in Boston (I did not know what Bottlehead wa all about at that time). The meeting was...
