[quote user="Romy the Cat"]rowuk , you are not wrong feeling that what we do with
PS and Mains regenerator is kind of ridicules. Indeed we convert AC to DC, then
to AC against and then to DC again. If you use SS then it very much makes sense
to ru...

Power cords is the
most ridicules subject that I have seen in audio and they define all rules,
would it be stupid rules or sensible rules. There is absolutely no difference
in power cords construction, built quality, price, material use, insolatio...

Well, I would say that “something is wrong” as what you report it is not how it shall be. I had my doubts about the rational to use 6C33C in direct heating coupling but the “danger” in direct coupling uselessly coming from the plate of the driver...

Well, the conflict you pointed might sound reasonable but not completely.
The First quote is taken from a thread “Disregard Digital with Vacuum Tube
output”. In there I advocated do not look into D/A converters with tube output stages.

[quote user="Romy the Cat"] I do some very interesting experiments with Rohde & Schwarz tuner. Dima and I have discovered a way to use the Schwarz without the wide bandwidth amplifier, driving the Multiplex Decoder from the Schwarz’s preamps. Bas...

[quote user="RF at Ona"] Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers...

[quote user="Romy the Cat"]Generally I like it but I have some concerns, whatever rubber
feet and decompiles you will be using you will not defeat the vibration if you
have a few transformers and a few 500A input chose sitting at the bottom. You

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

Well, dealing with Purepower I think it worth to understand the APS specific. They did not impress me as an engendering shop but rather they are the long-ceremony type of operation. It is not that you comment on some kind of problem on the fi...

A week or so ago I spoke with a friend of my - he is a perfectly rational and sane person. I send his some music and was asking what was he as thinking about it. He admitted that among the music I sent him he admitted that did not get opera. I was pu...

[quote user="KOTriode"]Romy,I have good confidence that it was the tubes and not the circuit. I have checked the cathode driver that bias the 6C33C and there was not any problem. Sure if the cathode bias failed, the 6C33C current will shoot way u...

[quote user="George"] Even though a PS Audio and others create a perfect AC sine wave this does not seem to be the answer, even for low draw front end components. It seems that some type of problem is still coming through. [/quote]

I was searching for an answer why squire wave is so screwed and I was advised by the site’s visitors that it is due to HF restriction of my channel. My HF response does look too low to me – the 23kHz; with all my ultra low capacitance magnetic I ...

[quote user="rdrysdale"]Romy, I just got a Vitavox S2 into my shop today. I notice that it has a very heavy stainless screen on the front, do you leave the screen on when using the drivers? It looks like it restricts about 50% or more of the thr...

[quote user="Romy the Cat"]I kind of like that APS stay behind of their regenerator and that they are trying investigate what went wrong. Who knows, perhaps when the APS unit arrive back to me (after some changes in the unit state) it will be effecti...

I would like to offers some thoughts about possible avenues for Pure Power 2000 improvements. Those thoughts are no specific to the recent November-December events and have broader generic implication. I initially intended to write it to Pure Po...

Zdravstvui Roman, hi Chris,
I know almost nothing about the relation between sonical effect and
physics, so I will only try to speak about the latter. Take it as you
wish, I can as well delete the post if it just increases the
entropy.

user="jackydai"]My basic point is: the flare rate has to be coherent
right from the entrance of phase plugs. In this sense, not even Bruce and Sam
did it right, I’m afraid to say. In many cases the driver and the horn are
