Well, leaving aside my "grinding axes", namely my habitual love to remind people and myself that there are plenty Morons in audio I do think that Berkeley's parley to Reference DAC is interesting. It is interesting not by the DAC as a unit but rather...

A few comments. I think the region that impressed you was somewhere 50Hz-500Hz, the melody range with all those fundamentals. It might appear that it was in the lower end but I think it still was the fundamentals with first overtones. Since you c...

[quote user="jam"]I would agree that the RX-5000 has some advantage to the SX-8000 and I put the differences down to mainly the air bearing and construction of the platter which will cause softness and a lack of focus (some people may like this). T...

Yes, I saw that a week or two ago and was repulsed not so much by the price (which is extortionate) as the implication that recording in this fashion will give superior results to using the best digital techniques availabl...

Lawrence,
Here is the Webster Online Dictionary (http://www.merriam-webster.com/dictionary/moron) definition of the word Moron:Definition of MORON1usually offensive : a person affected with mild mental retardation2: a very stupid personIn this thre...

That all interesting though but the problem is that they have no way to be absolute valid. Yes, we as a humans, have a lot of masking effect build in us that prevents up to get complexity and color of sound with dynamic range rises. Yes we do in many...

The Targeted Audio Listening has nothing to do with general music listening and it is just an ingredient of a very narrow audio evolutions. It might be as stupid as just brainless acknowledgment of individual sound or as complex as assessment of...

I was slowly looking for a compression driver that would go in my Fundamental Chanel down to 200Hz. The YL Acoustic 550N attracted my attention. Then I realized that it is the narrow throat type of the drivers, aka WE555, not exactly that I would...

I initially meant to put this post into my midbass thread (linked above) but then I decided that the subjects is self-important and it worth to separate in standalone thread. In fact this idea was formulated to months ago but I was holding to po...

There is a new company out there that make some electronics. I do not know them, never heard anything that they do and do not know anyone who use their products. They have a phonostage that might be interesting.

I am kind of semi-evaluating a power amplifier now and think about the following: there is a correct relation between harmonic content of amplifier and it’s dynamic aptitude.
I have heard many amplifiers that run across the dynamic range with a tre...

[quote user="drdna"]Romy, I think you are asking if I have the Edgar subwoofers also. Yes, I do, like giant woodgrain refrigerator in the living room. So I do get some bass response. [/quote]
Yes, I was asking about the Edgar refrigerato...

There was a Reference Recordings company that did some nice
sound and sometimes, unfortunately much less frequently, some good music. The premises
behind the Reference Recordings that they were pure PCM recording, uselessly
done in 4x with Pacific...

An Audio Amplifier Design Philosophy

[quote user="jessie.dazzle"] If I get you correctly, the graph should display a range of around 12dB from top to bottom, in .5dB steps... Yes? [/quote]Yes, it would do, you might go for high or lower resolution, and there are no rules in it. You shel...

In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

Paul S,I usually do not compare source components (or amplifiers or cables or etc.) in this fashion, DAC vs DAC, CDT vs CDT etc. unless I feel two (or more) of then (may) be too similar, like Lampizator and AN UK DACs I like. I prefer to focus integr...

You know, I frequently tend do not listen operettas on LP. Operas are serious, dramatic, requires attention and dedication. Operettas are much lighter genre, no less wonderful but light and less “loaded”. I love operettas and I frequently liste...
