Dima for instance (and he has quite high expertise in the subject) claims that there no true 24bit converters available anyhow. BTW, with all advances of HDCD, that I fully appreciate, it makes send only on 16 bit. At 20...

It was an audio eventful year and I have experimented and discovered many fascinating things. Here is a brief summary of the 2007 audio-events and a short look what my audio happening will might take please in 2008.
1) In the very ...

The Dima’s idea of delaying the modulated signal still not in the auditable format. As I understand he designed the circuit and we get all parts we need but it moves forwards slow. The devise will have modulator, delay mechanism, demodulator and outp...

Romy and Dima,
Thanks for the update on the delayed Time Delay research. I sincerely hope the device performs to your expectations.
I will follow your progress with self-centered interest, because in my case, the best scenario still puts the ba...

Hi all ! I thought about this resistor bias idea that Chris proposed , and found some some problems here . One of them discovered Chris himself - it is a big serial resistor in the grid chain , and it can cause not only HF rolloff ( it isn't a big pr...

But here it is. I made this monoblock fit into less than a square foot. It is tight. I use Hammond iron throughout. Their stuff usually works pretty good for power supplies. I have some photos at my blog. [img]http...

[quote user="drdna"] First, I do not accept the hypothesis. We must confirm that the Avicenna was working correctly when no impact on the sound was made. It has happened before that a simple mistake in observation led to a faulty hypothesis. It must ...

I have very little familiarity with SS and with the need of
the SS stage to be driven. If you want then talk to Dima directly or over the linked
site, he is comfortable in English. www.tornadoacoustics.ru/_fr/2/Zarathustra.doc
I would sti...

Chris,
Since I got that mind-boggling result with “Melquíades” (will finish the thread about the Melquíades sound) I went for an “ultimate solution” for my installation: a “Super Melquíades” amp. It will be dual chassis (amp+PS) 3-chennal amp to mil...

While Dima is cooking the Super Zarathustra I figure out that I would need some test speaker to be able to observe the preliminary results. I would not be able to drive the multi-channel Macondo with a single full range amplifier, so I need something...

Chris, I have no experience with good sounding SS amplifier that might drive high sensitive horns. I also have no expertise to build such an amp. From what I trued before I have learned that in order to sound more or less acceptable the SS should run...
|
|
.. and therefore I do not know how serious to take you.As far as I know as now there are no people who have built Melquiades. I know that up to now about 5 attempts to do it but no one finished it yet up to the point that might report result. Dima is...

Alex, I do not remember already the volume of those boxes, what is the deference? Thos drivers have an average sealed Qs and Fs I believe 19Hz, you might easy to circulate any volume you want. I slightly overdamped them, as usually, form where they s...

It is interesting: I am running now Zarathustra amp with my woofer towers, line-level crossed at 90Hz with fist order. Everything is very fine bass-wise, with very minute touch of dominating smoothness. To my surprise the typical upper-bass har...

After learning about the Schwarz’s circuit Dima declared that it will be very simple to build into the unit a good quietly multiplex decoder as the plug in modules as a substitute to the original modules. This will change nothing in the Schwarz but t...

I do some very interesting experiments with Rohde & Schwarz tuner. Dima and I have discovered a way to use the Schwarz without the wide bandwidth amplifier, driving the Multiplex Decoder from the Schwarz’s preamps. Basically we put two stages wit...

Since FM long has been my primary at the most enjoyable audio source I decided to push the envelope a little further. The Rohde & Schwarz tuner bind via wide-bandwidth output with modified Yamaha T-85 MPX decoder sounds identical to Sansui TU-X1....

[quote user="drdna"] Well, and I have a dozen of them sitting here next to my desk while I am building my Milq amp s-l-o-w-l-y so I guess I will discover my audio intelligence level sometime after the New Year.[/quote]

Well, it is not necessary a fully qualified urban legend as the problem does take please with fixed based 6C33C but..... only under certain conditions. I have written about it a lot on my site but will very briefly recall it again.
Dima might be cor...

Above, talking about APS-like regenerators, I was skeptically referred to the battery back up functionality in the APS PurePower, calling it bogus and completely unnecessary. It was very funny to read at the APS site as the APS guys promote their uni...

First of all it is not Baby Melquiades anymore as it be...

What might be very interesting also is to learn what DC coupling in power amps would do generally in term of Sound.

Splitting the Lamm ML3 thread: http://www.goodsoundclub.com/TreeItem.aspx?PostID=3595
There are some people who worship direct-heated tubes and attribute to them some ventures (like absent of higher harmonics and a special micro-fineness). The...

Jim,
in my corrector (Dima’s design with R2=50R) I made many experiments adjusting the VR1. Dima proposed 150V on 7788 plate purely arbitrary, what he did it he never ever seen 7788 and it was just a concept RIAA for him. After it was built and I p...

Yahoo! I was able eventfully to educate myself how to get out of the “Melquíades” the sound that I needed (using some blood injections from Dima)! Now the project with the “Melquíades” amps is slowly converting from a labor to a pleasure!
