Yes I think we need to move on from PP and yes the question is how to do it. This should not be a major theoretical nut to crack. Double conversion units are plastered all across the world. In my investigations, the one issue with the commercial doub...

in the last years there was lots of development in field of DHT preamps. new circuits, or old circuits becoming practical and useful - especially related to hum inducing DHT heating issues that used to affect the sound. now you can basically have a s...

Romy, You mention using a commercial air blower ionizer as an accessory in your system. Do this serve any audio purpose? Michael P.S. I like the look of your site. ...

Hi Romy,Is there any reason why you haven't expounded your ideas on SLLB beyond level two?Although I've really enjoyed reading your site on-and-off in the last 6 months or so since I came across it, my feeling is that I've only 'really' understood 20...

is what comes to mind when I reflect on your ponderings.There is a difference in "real knowing" in e.g. how to ride a bicycle (arse in the saddle), and then you can read a book about it, and then some more, and then write some PhD on the subject, yet...

Wine is very much like audio, as a matter of fact. I was a wine merchant for 10 years before my present occupation; when I started, I enjoyed wine a great deal and typically spent $30ish per bottle, occasionally ramping it up a little for special occ...

Paul, I'm not rushing to the breadboard. I'm trying to visualize if Romy's constraintscan be satisfied. I have to gather more data on GU81 to think of doing anything.How linear it is?? Perhaps this tube is an audio no-go as you've mentioned?Going to ...

Hello, My first post here. I was the one who emailed the news about Orgue to 6m. I bought a pair of their Reference speakers and am quite happy with the way they partner my Shig integrated. They sound rich and clean but I'd say they are a little opti...

[quote user="manisandher"] This is of great interest to me. I'm having a dedicated mains circuit installed and was wondering whether the PP2000 would simply corrupt the line that feeds it. Romy, any idea how best to measure such 'dirt' going back int...

Dear Romy,You said that PS Audio never acknowledged any sound problem with old PP. Did you ever identify something "technically wrong" in the sinewave that a PPP outputs that peoples from PS could work on ?May be I miss your report on that point but ...

CJ Yes I have assessed AC polarity in my system.Romy says "I took today my large
3kW isolation transformer and place it between my dedicated line and
PP3000. I lost my lower bass, simple as that. "Speaking of isolation transformers, I have not h...

I am not a DIYer and have no skills nor knowledge to build the Melquiades, so I contacted a technician here to have one built. He said he could make it and stated the cost at around 3000USD including his working time. He suggested some changes in the...

Romy, thank you for the very useful info. You have given me hope! When I contacted CEC in Japan a year or two ago asking to let me buy replacement lasers (as many as I could) they said no (they did say they will repair the unit if it ever fails - if ...

I have to admit that my first unsuccessful experiment with APS PurePower regenerator made me anxious like hell. In context of the none-loaded unit I’ve heard some results that I was searching for a long time. The APS claim that they have “fixed” it a...

This is always good advice, to get to know the character of the phono stage. Because my favorite cartridges are not low voltage (I use Decca London Jubilee and Reference) I have never had a need for the ET SU-1 step up unit. In fact, I had this in my...

I am somewhat familiar with the dact: I used it in non controlled manner but familiar environment; it was assembled by someone else who also provided the necessary power supply; it was in two chassis about 15x15x~30 cm each (one for ps), so the equal...

It is OK, Item. It is a common for people who sell audio to be not completely informed what they are selling. That comes with territory. You might discover with time that audio is much more interning then just to dump a pile of BS on people and to ma...

I wasn't talking about solution by PS Audio, but rather the idea of using iTV from Apple for a player. It is not a hand held device. Also, one can replace a HD with bigger one and iTV is chip. The key is, that there is a digital out (fiber opti...

YES! Now who wouldwant to argue, or even pretend to argue about that?!You will of course realise that a lot of audio interested people have had their 'learning path' as you have had your 'learning path'. This implies if playback improvements where re...

Romy --Well you must remember, there *are* two schools of language. There's the Harry style you talk about, and directly on the opposite shore we have the Ivor style (Tiefenbrun of Linn) that emphasizes pace, rhythm and timing.We really do have a ran...

[quote user="Romy the Cat"]You would not need any “special” A/D converters, as I did impose any demeaned to “quality”. All you that you need to have a more or less reasonable tuner, a good antenna, strong reception and an ability to write it up at 24...

Romy, I have that Macondo post printed out and used for a basis of very in depth discussion with my audio companion in confirmation of understanding it. So it's not in any way a matter of disregard as you assume. It just makes your point in great...

We still maintain that the output is totally isolated from the input AC - which after all is the reason for a battery pack - to make sure the DC bus is always stable. We have done tests again and again in which we switch from battery to utility and...

I’ve been thinking about all this electricity stuff…
I’ve stopped using all power conditioning devices since Bush got re-elected, and I consequently left the country to start a new life in the land of 220v/50Hz (this BTW, is not an exaggeration).

I would like to shade light about what is doing on with PurePower PP2000. I know that the readers of my site have own brain, at least some of them, and they do not need me or anybody else to “shade light” on anything. Still, since I was the initi...

I admit that regarding many subjects in audio I love to sound, to act or just to be a compulsive. However, I feel that my compulsiveness does make sense to me and ironically it does make sense, quite frequency, for some others (unless they are Morons...
