The VERY INTERESTING idea is that the introduction of noise as a dithering element for the analog signal (for our brain to decode) can be helpful in increasing the retrieval of information vital to conveying the Sound. Perhaps ...

This might be an excuse to get/play with the Sound Man's staple, the parametric equalizer (analog units are still available). While it is possible, it is not probable that you will wind up wanting "flat" reinforcement of the sound just as the mics "...

This type of "re-constructor" appeals to the side of me that still wants the "perfect sine wave", which most of the "manufacturers" still insist is [the key to] their units' "success". That the unit in question does it with a "conventional" A/B amp ...

This mooring I decided to play with my infinite baffle. The
mess with my analog crossover hat was calibrate for my old listening room gave
me bad IB taste. I bought used stinky Behringer DCX2496 Ultradrive Pro crossover
for $100 to find my new cro...

Gera, what sort of active X/O are you using there, for what sort of music/expectations? Doesn't your X/O have a buffer already? There are plenty of pro solutions that combine the X/O with pre-amp functions, including the ability to drive long IC runs...

Here is there the “crazy” Stitch bitching about the “The Foolishness of Analog People” and about new turntables/arms the Morons invent each month. Those new turntables/arms are somewhere at borderline between absurdity and retardation and to their be...

No one else posted this, so I'll take one for the Team by mentioning Fremer's May 2012 Analog Corner article in Stereophile. Apparently, Fremer has gotten at least two high-dollar Lyra cartridges with indifferent stylus-to-cantilever mounting. I co...

Well, some say, he loves reading those postings, others think he raped his grandma or (and) will be responsible for the next earthquake in California, some bet he was a member of the well known German Anonymous Audiophile Alcoholics and left them bec...

What really pisses me off is that my second arm/cartridge has a very strange effect that I did not see neither in this arm (Micro 282) not in this cartridge (Ortofon SPU Classic). I am taking about dynamic compression. In fact it is very seldom you c...

With new MF amplification and change of Macondo reconfiguration I found myself to play a lot of analog lately. In addition to anything else I kind of interested in getting the “new” Macondo’s imaging pattern and LPs are the best tool to do it. With ...

Thanks for information, Gordon I am a skeptic about this DAB+. Whatever amount of kBits they select it will be still digitally compressed format. So, it will be one of the versions of our HD format. I presume it will be better then HD but I down tha...

I think this has not typically been used for FM, but it is my understanding that some FM stations used to use something like this to monitor their own broadcasts.Who knows how it has changed over the years, with digital, satellite and cable broadcast...

How can we compare anything if we know from the very first note what media is being used? The noise floor and sonic artifacts are unique to each media, so are we talking about confirmation bias? Let us assume that we have a first generation analog ma...

Depending on the UseCase, many things can influence the sound. Rectifiers, snubbers, impedance, corner frequency, speed, an inductor in series, regulation, isolation from the mains grid all are parameters to consider.I do not know of any really serio...

A 192 24 bit capable DAC and a little dedicated Linux PC to play the stuff... Apparently I spit out whatever the recording is recorded in frequency & bit wise and this DAC does whatever to make something approaching analogue.So it's err... bette...

Oxric, I have no idea what your “literature” was all about. If the Item’s company does not name thier read-only DAWs as “transport” it would be no conversation at all. For sure the analog PS for PS that they do is very interesting thing and very much...

[quote user="peter foster"] 3) I have been swapping DACs in and out of the chain to compare results. When using my Lavry DAC there definitely is additional background noise. This is unexpected and annoying. [/quote] Peter, I am very convinced that th...

While the aftermath of the midbass horn project is not over I am strategizing how I might implement Macondo’s LF section. The leading idea is to bolt a triangular shape sealed enclosure juts behind the small wall that cover the load bearing beam from...

Yes , the idea of time delay machine is completely clear now . I made some experiments with analog and digital parts of the circuit , ewerything OK , and I need to assemble all the parts together , but now I am finishing the new hybrid class A amp - ...

I've been kicking around the Stupid and Lazy Version of this for some time, where one simply runs two different, "characteristic-[un]matched" drivers on the same frequency band. Oops... So, why not the same drivers pushed by the same amps that a...

Too lazy to research it and, rather than mentally invent new technology, I keep thinking, "cutter heads", like the old, analog "lathes" that cut the metal masters. This has to take some real force, perhaps analagous to a speaker coil, and I diml...

[quote user="hagtech"] Please do. I have interest in the result myself and don't mind spending the time. I can post photos for each tube. [/quote]
Sure, let do it. Email me your address and I will send them to you. (Do you have sockets?)...

Sorry if this is a trivial question already answered somewhere.I have just finished installing 3 dedicated lines for analog source, digital and power amps.They run directly from the house power meter, with a dedicated subpanel, each individually fuse...

I listened to Purepower 3000 we finally got it in iran.it is wonderful , new level of dynamics , far better than direct utility.I have a question about pp3000 if you had it in a ultra transparent system.our system is not ultimate in transparency and ...

Romy,
Thank you for sharing the link!
The second part is better!

We only use the Beringher for bass under 100 hz, driven by the main amp.
We tried a lot of different solutions, including analog active xovers, the DCX is cl...

I second advise on microscope purchase. I went recently with my Grado Sonata to a friendly Audio Dealer who carries analog for many years and he said that he never saw a worn down stylus. He saw only damaged ones. He stated that it is like wi...

Paul, I think that is a very good observation. Seems to me that a really thick grease or oil in a large bearing would offer enough friction such that the motor was always biased into an active positive torque region. Such would be the equ...

I tried for a few years - many years ago - to put together a tape-based system. The prices kept going up on equipment and recorded tape, and program kept getting more scarce, until the "secondary market" kicked in. These were the "Bait and Switch" ...

i checked out this product from your link(thanks).for digital inputs they show aes,spdif,toslink and bada,which i understand is for use with the rr hrx 24/176?.also there is no clear indication that the attenuation is achieved in the digital domain.t...

Romy, you mentioned the output separately and John Wright also puts great emphasis on what he calls the "analog" part of the DAC. I haven't even taken the cover off the thing yet, but the way the power supply is implemented is so simple, i...
