[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...

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"] 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"] 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...

Dear drdna,I agree with you, my explanation was a little audio reviewerish! If you noticed in my first post I just mentioned Sussarro being different to other Moving coils of my experience. To me it has advantage of high compliance cartridges in conv...

I agree completely drdna. I think the current editor of Stereophile is setting the tone...he is known to be an opportunist...in fact if you read some of Peter Aczel's criticisms of him in the past, he, along with pearson & others, are the ultimat...

[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"] This is why the discussion of the Injection channel and the use of the loudspeaker like a resonant musical instrument is so apt. [/quote] Indeed, I did not realized that I shifted my thinking in this thread and an in my general v...

[quote user="drdna"] So many years ago when everything was very dry solid state, Koestu cartridges were like a wonderful spash of color. Then it was the fad of the soundstage. These days I think it is inner detail. This is what the Koetsu Onyx is bui...

[quote user="drdna"] Option #2 is appealing since it will free up a lot of space and make the equipment more cat-proof. I was thrilled to come home a month ago to find the tonearm wires chewed through and the tonearm swinging freely. [/qu...

[quote user="drdna"]It is important to remember that the Subjective musical result is the goal, but this does not mean to disregard all objective data. When one sees something as ridiculous as the Brazilian horn, you kind of have to assume obje...

[quote user="drdna"]While I think it has a lot of potential, I worry that the added complexity may lead to new problems that may outweigh the benefits derived, even if it is done very carefully, one of which is time alignment as pointed out.[/quote]H...

[quote user="drdna"] BUT, I think it is more exactly what you say that the midrange horn is round and the lower midrange horn is rectangular. They sound different and it is more easy for me to hear the presence of the rectangular horn. [/quote]...

[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"]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...

[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 ...

[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 ...

[quote user="drdna"] Honestly for now, the character of the tuner is unobtrusive enough that I notice mostly the problems I have with the preamplifier and the electricity. However, I would be interested about what you had thought at this point to be ...

I experience as do some others a variation in the effectiveness of the PP at certain times of the day/night cycle. Since it seems correlated at least partially to probable power co usage it seems reasonable to ascribe the variation to an isolation fa...

[quote user="drdna"] For stereo systems, we start with two small microphones with strictly limited ability to capture an acoustic musical event at a particular combination of phases, reflections, amplitudes, etc. in a relatively low-level voltage sit...

[quote user="drdna"] The altered topology of DSET has the potential to have disadvantages. There is increased overall system complexity and this often seems to be a negative. Beyond this, it is difficult to expound, for me, on the specifi...

Hi drdna, Three things that I have found that can seriously damage the performance of our horn system is: Speaker location, heavy gage or multi stranded speaker wire, and room reflections. When you locate the speakers, m...

Well, on your London trip you could certainly visit, or stay at, The Lanesborough, and smoke some really good cigars whilst reclining in a leather-backed armchair in a library. It's very pleasurable to recline in this bar on Hyde Park corner, watchin...

[quote user="drdna"]I had tried this before, a few years back, using parallel runs for interconnect and speaker cable of uninsulated and insulated wire of different metals. The end result was that the tonal result was very similar and basically the t...

[quote user="drdna"] When I had a record with a stain on the vinyl NOTHING else would touch, he sent me some "special cleaning mixture" that took it right off and the record played like new. [/quote]

[quote user="drdna"]Easier to make might be a device like a record clamp you can attach to an existing turntable platter. It should be easy to do the experiment by trying a weight on the turntable platter: 1. a solid weight 2. an equal weight contain...

[quote user="drdna"] Oh, I see you are absolutely correct. I am very puzzled. As it says on the website, the mastering studios relocated to a new location. Maybe there was no room for the old set-up. I was only in the old studio a few years ago. I sw...

Thanks, drdna,
I personally inclined toward the BC scenarios. I’m thinking to hard-couple the platters using a fairly high force belt between the platters. It would allow handling the micro-playing sin the bearings and make the momentum (kinetic ene...
