[quote user="Lx_"] The second sentence is my own conclusion. It was not my intention to imply that it is yours, sorry for the misunderstanding this may have caused. We both agree that PP can be sensitive to incoming AC. The context and circumstan...

Since Sound in new home is mostly set I kind lost interest to do anything “project-wise”. I play my music and I gradually tune ingredients to get the sonic mixture that I accustom to. Last two week I was slowly playing with my analog setup. Since...

[quote user="Romy the Cat"]I was thinking about this: how come that driving 6C33C (in fact driving anything one can imagine) the 6E5P was very fine but driving 2A3 it was dull like hell. I opened the amp and tested all – everything was perfect but th...

Joe, I do appreciate that that invitation is open-ended and I might take advantage of it sometimes. Frankly I do not feel any specific temptations that I need to “drop everything” and to run to another side of the globe to audition the Silbatone. The...

This thread has been pretty interesting overall. I've read most of it and would at least like to provide some feedback on the technical side of designing with the 45 and 2A3 DHTs... at least from my personal experience. A few years back I decid...

It turned out that I end up with 4V tubes for MF channel and am running my YO186. The 2A3 tubers I kind of have left on peripheral of my interests. It is not the 2A3 tubes are “bad”. I did not go deep with 2A3 and did not try their expensive sin...

Perrew,
LCR is not active at all; it is the very same passive EQ as your RC? I think you a bit confused with terminology. The main logical explanation (there are many of them) is that capacitive filtration is very bad one and need to be minimi...

It looks like a new horn maker wanted to be know: the Eleven Horns

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...
|
It is not surprising that the subject of horn is as screwed as the subject of drivers. It is understandable as driver must be made for specific horn loading, not one make drivers properly, so what the horns are made for?
A horn is a very simple dev...

A few months ago a reader of my site contacted me and informed about that he found a very interesting driver, that his is using and he is very excited about it. The driver is JBL 2490.

I remember when I built Melquiades I detected that quietly of wire that feeds the grid of output stage with bias, quality of soldering or any other minute detail on this wire was very auditable. I also detected that the proximity of this wire t...

Being a Russian by birth and inheriting all typical for Russian masochism I sometime visit the High Efficiency Speakers Asylum, laughing me sick tail off. Between the fresks in there patting each other and the mercantile cretins who pose themselv...

My friends, considering my heritage, frequently ask me about my suggestions regarding “Boris Godunov” and I decided to compile a little and highly opinioned (no surprised here!) “surviving guide” about this opera.
It is well-known and well-told stor...

Jeremy, another few lead that I think might conceder.
Manly Labs has their 20-bit digital to analogue converter that uses the Pacific Microsonics processor inside. I was told that is available as the “street price” for ~$6K-$7K and it might be a “f...

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

There is always the argument that if you can't hear it, it can simply mean that your hearing sucks.......

It certainly has nothing to do with my ear or with being
acceptable. We attribute too much attention frequently to a topology/hardware and
too little to specific efforts over given implementations. So, what is the
subject? The Multicellular horns?...

I disagree with an idea that PP
introduces different grounding schema into system. I mean it does and it
does not. Anything the in your power pass induce different grounding schema and
PP not different. I personally did not experiences that PP int...

Will try to answer all questions here.Romy: I understand why you do not wish to use the term “surround sound”, but it is the accepted term for what we are discussing. You may add other terminology, but it only muddies the debate until others accept i...

Paul, what I mean by 'Drain GND' is your idea of a GND cable connected at one end only. I have no access to mother earth and cannot install a dedicated rod. To avoid confusion, below is my actual power line and GND scheme.

I have no dog in this fight, in fact I have even no opinion on the subject. However, the subject is kind of fascinating and ridicules at the same time.
