Now I re-listen all the things the we try to measure. To surmised everything I have to tell that Dima’s way to looks for optimum operation point of the tube (setting balance for voltage vs. current sufficiency) turned out to be very successful as I d...

Glancing a few days back over the latest TAS magazine I come across at the first pages Robert Harley’s article about a Asian guy who has zillion turntables, speakers setups and listening rooms in his home… Robert, wrote in his blog about that guy: “T...

I have started a project that I want to share with people. I have the
Decca Solti Ring boxed set. I don't listen to it much because it is
difficult to read the libretto and follow along with the story so I keep
getting lost and it is kind of ...

Eventually the right channel of the last revision of the 6-Channel Super Melquiades is complete. It has the new dedicated power supplies for single-stage amplifiers, the 600V Schottky rectification for 200V line and 1200V Schottky for 400V lines, the...

It looks like Purist introduced a new line of cables: Proteus Provectus. Dave Clark from “Positive Feedback” made a write up about those new cables. Hmmm… I do not like what I have read, particularly reading some things between the lines:

[quote user="clarkjohnsen"]Since all audio folks know that the wall gives us highly variable power (voltage being just about the least important aspect), it occurs to me that a way to measure it that includes all the various parameters would be highl...

[quote user="Kcct82"] I know you're not a big fan of digital delay, but I'm using behringer DCX 2496 to make things easier... this way I get to keep all horn mouths on the same plane which avoids some reflections (from other horn mouths). [/quote]

As usually I tend to see a generalization and patters. The very same is the case of that Brazilian installation with those Japanese hors. However, I would like to take it even further then just the very questionable design decisions in that upperbass...

[quote user="cb"] Yes, it is imposable to have + 0.4V on the grid, 0.0V at input, with R5 resistor in place and the gas tubes outputting +150V and -150V. My apologies, I meant to say I have minus 4.4v on the grid with the inputs shorted. Then I...

Eventually I fed the new Melqs with another pair of power transformers for output stage. I ended to run the 6C33C very-very moderately at 180V and 200mA or at 36W. I think it is little bit low and I could add 3-6W but I prefer to keep it for a time b...

What I found captivating in the story of the Living Voice speaker is the he motivation of the Living Voice people to go from their former model to this new one. This itself. is a very interesting to me subject.

I’ve been harassing my horn-maker for quite a while with an idea to go for straight, no-cheating 45-50Hx horn. We discussed it countless times and sometime probably we would go for this, and particularly if I figure out how to resolve the delays prob...

Adrian,
Are any of those new tubes besides the Chinese tubes are single plated? I have bought some very nice 2A3 and 6A3 double plated from 1942 and 1944 and it will give me an ability to see what is going on with vintage tubes.
I was not ...

[quote user="Gregm"]It doesn't seem prudent to look at the speaker without considering the amplifier at all. We would be designing a speaker that would work with a theoretical amp -- but not one that's available.[/quote]
You are right but the opposi...

Very good, thanks for the images. It would be very interning to learn what the bandwidth of the horns, the bandwidth of the drivers and the specificity of crossovers you eventually chose to use with each channel. It might take for you for a while to ...
