Post Subject: Some summary and conclusions from the first phase.Posted by Romy the Cat on: 12/9/2008

I would like to overview the content of my thoughts on the subject. I feel that the first phase of my interest in single-stage Milq vs. DHT is over and I can make some observations.

 The subject turned out to be more interesting and more changing then I expected but it was also more fruitful then I expected. It is important to understand that the subject was not about the DHT vs. High Mu tubes as “nl” put it. I have no interest to make general concussions and my curiosity is much more egocentric – I egotistically care about the sound of my Milq-Macondo and frankly less care about compliance of violation to some kind of DHT practice out there. So, what I discovered?

It looks that there are some very interesting characters in sound of DHT tubes. However, I do not know for now how to capitalize on them in the applied sound  as Macondo is multi-amped system and I have no idea at this point  what would be cone and pros  of DHT used if I mix DHT and IDHT amplification with Macondo. I do not anticipate any problems but some corrections of Macondo or Milq operation most likely will be warranted. Admitting that there are some interesting moments in DHT I also observe some negative moments (lost dynamics, lack of clarity, deficiency of intelligibility, lessen articulation, colorations) that I do not like. I think  to move further in the discovery process it would be necessary to built a “clean” brand new DHT amp and to see if the DHT’s negative moments will be gone.

Thinking about positive properties of DHT sound and analyzing the differences of DHT and IDHT some observation and proposals were made how to “tweak” the sound of IDH tubes and to take their performance taken slightly in another dimension. The proposals were tried. One of them was natural injection to the sound of IDHT the harmonic context that is atypical for IDHT. Even though it did not lead to sound improvement in the direction that I would like it to be but the method itself turned out to be VERY interesting and promising. I am planning to experiment more with it and when I have conclusive observations about the ways to do the things and benefits of it s use then I am planning to post all information about it at my site. The second proposal was the randominisation of elections flow and I have to say that the result was instantaneously extremely positive. In fact it was so positive that I feel the method has quite high commercial value as the result were very good and anything like this never was done before. I pitched this idea to an industry-involved friend who might take it farther commercially. So, for a time being the second proposal will not be discussed further.

So, does mine IDHT single-stage Milq, improved by the above motioned “proposal” and become “competitive” to DHT? I have no idea. I do not even know if the DHT would be competitive to single-stage Milq in general sense. I think a “clean” DHT shell be made to take this debate anywhere further in practical and relevant terms. Talking about practical and relevant terms is very important for me as I would not like to change anything in Milq-Macondo. This weekend I was listing a live broadcast of Handel and Haydn Society’s Messiah. The electricity was not bad and the general sound was fine. I turned my attention to “target listing” and was trying to observe specifically the sound of my MF channel, trying to assess what I would like to improve. I did not experience any frustration with the sound as it was; in fact I liked it a lot. There was in it some kind of “super correctness” with no character of own. When sound had to be ugly it was ugly, when it had to be beautiful it was beautiful, when it had to be brute it was brutal, when it had to be gentile it was gentile, what it had to be elastic with flexibility to change of meaning with volume or tone then it was. It was exactly where I need it to be.  So, I do not particularly have any motivations hypothetically to ruin what it is with DHT rubes. Might it be no “ruining” but advancing – I do not know yet, in some aspect it might be. I do not know at this point how valuable will be those “advancing  aspect” and how much effort and compromise I would need to sacrificed to get this alleged or factual  “DHT advancing  aspects”.

So, decided to calm down with this whole DHT saga and to see what happened next. It might be another “cleaner” DHT will come my way. It might be I will build or buy some kind of DHT prototype where I would able to look at the DHT sound deeper and more in context of the whole Macondo-Milq integration. I would like do not do a lot of work with it myself, so I might get some kind of DHT kit that would give a necessary ground for further observations. I was looking for Japanese Sun Audio VT25 and 2A3 kits but they are too expensive juts for experiment. To make them to sound OK it would take another $500-$1000 – too much money and work as if the DHT turns out to be a good direction for my MF channel to go then the prototype DHT will be trashed and a new DHT will built in inside the 6-ch Melquiades.

So, let see if the Second Phase of my DHT curiosity kick in and if it does then let see where it would lead me.
