Paul,
Thanks for pitching the Johnson capacitors. They do not look “large enough” for me. I used in past the following caps:

They have very good size to value ratio. The ironic part that I just called to th...

This is kind if funny as I never thought that I will go this way. I kind of have a need for an amplifier. For a normal full range amplifiers that would be able to drive conventional speakers. I really can’t use the Super Melquiades as it has the live...

[quote user="manisandher"]I asked Dave Peck of Avid (formerly Euphonix) a few questions regarding the Model Two (otherwise known as the PMI). The responses he received from Keith Johnson (one of the original designers of the PMI, head of Referenc...

[quote user="haralanov"] Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that...

[quote user="cv"] I'm enjoying this account of Melquiades upbringing. I must ask though: how are you sure that what you are hearing isn't on the recording? Not that I don't believe you, I just wonder if the stuff has been there all along and undiscov...

[quote user="Paul S"]So this amp would not have to deal with a crossover? One R and one L in the signal path, it looks like a headphone amp, maybe a dream circuit for a light piston, HF only, given no cap/coil load at the [ribbon] driver. [/quo...

I am very much do not like the current state of my mind about the single-stage Milq. Let me to explain….
In 2001-2002 I spend some time trying to assess the sonic influence of PS to sound. After making numerous tests and prototypes I concluded that ...

[quote user="drdna"] You had described the Melquiades as a "reality Reconstruction" amplifier. In my mind, I have always associated the unpredictable quality you describe with a "closer to reality" sound in my system. [/quote]
Well, I might ...

It did not last long….
Just a couple days back I was thinking that I will live with my current lower bass for a while and now I feel that I will not. I do not feel that my current ULF is wrong. In fact I feel that it is truly superb but I wou...

[quote user="Kerry Brown"] For years, I used to have passive line level filters and tube amps - single ended 45's and 2A3's.
To make a long story short I am much happier now. Screw tubes ! ( Don't hate me. ) [/quote]
Kerry, I do not think that som...

[quote user="Paul S"] Romy, on Fundamentals channel did you leave the 20uF cap at speaker level or did you re-configure that band pass at line level? [/quote]
Nope, it is hoe it depicted the 20uF cap at speaker level. I see no problems with ...

I had one for about a week and was not happy. Switched to a Kenwood KT1100.
Here an honest review that matches my experience. Bottom line is that on stuff this old, the individual buyer will determine the price, not the market.

Greetings,
I may be able to answer some questions regarding crossovers, multi-amping, etc. - without getting bogged down, hopefully, in metaphysical issues.
First off, I live in San Francisco, if he's inclined 'drdna' and other locals are wel...

I never hit such a huge jackpot as I just did with the Lavry DA-924. The most funny in that even that I did it absolutely blindly. I had some minor beef with DA-924 sound: upperbass/lower midrange and the slightly too much extended HF (very very clea...

Horns are of course some kind of band pass filters with different kind of ripples at lover cutoff and beaming at upper cut off, according to horn type.
Maybe it should be added ...
|
|
[quote user="Ronnie"] Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order h...

I know, I know, it is absolutely not NECESSARY and I do not think that I see a need for it. I however see that it might be USEFUL in SOME cases when a recording was mastered by a complete idiot.
So, I wonder if anyone comes across to very high...

Anthony, the filter I use in
the tube filter is a regular RCRC filter, there is nothing special in there. It
has two buffers, input and output and it is it. The point you made is very same
as I do: if the digital and analog filters are the same th...

OK, after a few days to straggling with this damn tweeter I might report that the Water Drop actually made itself to sound civilized. It sounded somehow fine alone but it was a real nightmare with Macondo, I juts was not able to integrate it. I measu...
