I do not see any major changes coming in 2009, nor do I feel a need for them. Recalling all my dids and my thoughts here a brief outline of Audio Projects that I will be involved in 2009 and of cause anything else might come alone in future…

I have recently acquired a pair of (2000 vintage, I think) Lamm ML2s and would like to share impressions and development strategies with other ML2 owners, including former owners, and perhaps I may learn from any pertinent experience.
In addition to...

After a month of listening exclusively Melquiades and decided yestoday re-switch everything and to play Lamm’s ML2.
I was quite shocked with the result and I did not anticipate the ML2 could be so way off. I will not elaborate about the a...

[quote user="haralanov"] For some unknown reasons, he later decided to change it with the sharp and artificial sounding fostex supertweeter. What might be his motivation? Logically appears the following question – is that Goto supertweeter so hor...

[quote user="floobydust"] Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Yo...

Among many outrages foolishness that are so common among the people who going high-end audio one of the most ridicules is use of Single-Ended Triodes and low sensitivity speakers. The people who have db-meters between their ears instead of brain are ...

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 changi...

[quote user="cv"] I've only heard the 801 in class A2, but I can easily imagine that the 10Y or 801 with nickel output would offer the purest possible sound in the 1k-10k range, such that it is the S2's true voice you are hearing. It's something ...

Ok, I do not know what it was: was it DHT, was it 300B, was it some other specifics of this given amp or whatever… but those two aspects that I named: intentional density of colors and randomness of pace are something that I would like to exercise in...

Somebody from AA was asking about electromagnet. The subject pup up here from time to time but this time Bruce Edgar uploaded an interesting comment. Bruce is not a typical AA Moron and if he says “inaccurate things” then it is not due to ignoran...

Interesting….. It is interesting to think about the relational of Melquiades slow take-up. I think that major contributing factor is that guy who calls himself Romy the Cat. Really, I think it’s it. The people who are capable to build amplifiers more...

[quote user="Romy the Cat"] 1) It is not strictly audio project but it kind of related: I need to move my audio site out of my static IP DSL line to a data center. I have high-speed ADSL but the site has a lot of traffic and my crappy DSL li...

Ok, I made some further experiments driving this time my S2 driver from Milq DH DSET. The hell of the sensitively - it was too much. So, I went for 4:1 inner-stage ratio. The result was very successful and the amp looks like was able to get more...

A couple months back I sent to Dima a link with a wonderful collection of audio articles from first part of the 20s century:

In next couple days, talking with Dima he asked me: “Roma, what is REL Company a...

[quote user="drdna"] I know all the compromises involved with the EdgarHorns, I have heard them when I visited Bruce Edgar in Gardena, and they were pretty good compared to most of what is out there. I realized that I would likely never be able...

My string quartet have just spent 6 days recording haydn and being assaulted by nasty Genlecs.
I can assure you that this is NOT what I want my system to sound like.
(Actually I sort of began to see the point of them after a while.. but
that's ano...

[quote user="anthony"]Looks like I
spoke too early. When I made that statement I'd only tested the voltages
in the DHT Channel and they were pretty close to correct...but when I put a
tube in there it glowed a little too hot so I quickly shut it ...

Right. I do not mean to suggest that my
own solution for arriving at an acceptable global result using the
Milq full-range was not a short-cut with regrettable new weaknesses
(or just missed or postponed opportunities). But I am curious (wary)...

Romy,
Air core is ok, but. 1. Self inductance in an unmitigated field clumps. You can easily see this by unwinding a hockey puck style air core inductor and measuring the inductance with each turn removed. Never will you have the smooth loss of indu...

[quote user="nl"] Gordon Rankin of Wavelength Audio did a series of one-stage DHTs with a step-up transformer input about ten years ago. I think they were called the Mercury series. By all accounts, they sounded good, but of course had limited gain, ...

user="anthony"]I have secured a couple of pair of YO186 and some
1940's Sylvania 45's to play with. I wish the YO186 were easier to come
by but I think that I now have enough for me to get a very good idea of the
capabilities of the tube ...

But I
am curious (wary) about what you mean by the “one-sided” results of using a DHT
for the upper midrange (if I misread you correctly). [/quote]
What I meant is that practically no one uses "a good DHT...
