Romy, Just a few notes.... I did use the term "crappy" in the connection with the tonearm in an ironic sense. Have you lived so long among US Americans you lost your sense of irony? Also, i do not suggest crappy Phonostages, merely ones with low inpu...

I always say do not stress them they do not like it and I always hate third bass. The 10” are particularly are fragile with a power handling of a few watts. It is applicable pretty much to any lover MF driver that pushed to work with the “open b...

I was thinking about the subject for a long time. People in audio love to make generalization, so do I, but in it is not so simple. People attribute to output tubes some “special” qualities but I more interested not about unnecessary drooling about A...

Hi Cat,
[quote user="Romy the Cat"]I used my typical “flash” techniques and discovered some leeks in that 50 years old enclosure. Sure it the leaks were there then it would be no “acoustic suspensions” and the driver would run further. So, fixed the...

[quote user="drdna"] I am kind of disappointed, since you typically advocate a very careful and systematic way of proceeding. What do you mean by extremely different positive?[/quote]Well, I it what it is. I am not DIY-Moron and I do not do und...

Romy, thanks for your thoughts,Quotes from Romy in blue : "...I personally do not feel that you use Fundamentals Channel properly. You desired to run your Fundamentals Channel up to 3200Hz but it is too high..."Maybe, probably, yes, OK, I a...

I recently could not pass up a good deal on a EAR 834P MM, so I will have the opportunity to compare it to my current phono stage. It is funny since I had planned to listen to EAR phono stage in my system about 10-15 years ago when I lived in Santa M...

Well, spent a few more hours to listening Avicenna. Although it has much better sound then from the wall but there are a lot of moments in this sound that I do not like. It is kind of freakish and demoralizing as Avicenna feeds system with absolutely...

[quote user="serenechaos"]The Festrex 5" was good in a limited range-- but get it out of that frequency range and or dynamic range and it has real problems. And that is as long as the part that the drivers are $40,000 / pair doesn't bother you....

[quote user="Axel"] I hope I got this right when going through this long thread with LOTS of information. Did you mention for upper-bass cross-overs Elko’s (electrolytic) only to be your preference? If I have it right, any special preference at a...

[quote user="floobydust"]Okay, I think I understand.... and thanks for the link on the YO-186... if I can ever locate some of these I'll be sure to grab some (hmmm, a trip to Russia perhaps). As tubes get very hot internally, there were some procedur...

I have been observing High-Efficiency loudspeakers for a while. I think I have seen/heard many of High-Efficiency endeavors and I think that I did develop acquired taste and some experiences about High-Efficiency results. So, I would like to pass som...

I have no doubts that it will work but I would like to understand HOW it works.
The objective it to have first order filter, of cause not the filter where capacitance do high-pass roll off but RL. In RL filter there is not reactive elements i...

Well, in context of a full-range speaker, like largest Wilsons or the similar, the answer would be unquestionably no. Even if we biamp those speakers then the LF still is too wide bandwidth and too geographically bind to the MF section. The wor...

Yamaha B-2 reportedly was a top-flying amp in end of 70s, during it very brief production period. It has in a way cult reputation, so I’ve bitten it.
I was forced to very mildly and temporary modify it, just running the signal directly the ent...

[quote user="nl"] However, these sorts of basshorns with twin 15" drivers and a very large mouth (larger than the cones of the drivers) have a long history. The Altec 210 cabinet, as used in the Altec A2 systems with two 515-type woofers, is a prime ...

Mumford,
Let clear first with terminology. You post said about “Incorporating active crossovers into DSET” and I think it is not what you are interested; at least it is not what I am practicing. An active crossover implies a use a dedicated active s...

Dear Romy, regarding your efforts to solve variations in mains power supply, there has been an interesting thread on RAT related to the use of toroids as power transformers that morphed into a discussion about the level of DC offset in mains power su...

[quote user="decoud"] Romy, can you be persuaded to post a sketch of what you think the optimal 2 channel Melquiades circuit would look like? [/quote]
Decoud, I do not think that there is such a thing as optimal DSET. The entire concept of DSET is a...

Well, the LL1627A is very good universal transformer with phenomenal flexibility (properly done - with section not with tabs) to load the output stage. It might be a good choice for a full-range amp at 200mA, though I would still prefer to have a tra...

[quote user="RonyWeissman"] I have the 515-Gs If I remember correctly, and I am trying to find suggestions on what is proper horn-loaded cabinet still. And I agree my tannoy golds so far have worked best with early 70's mcintosh 22...

Recently there was probably nothing as low in audio as the BS surrounded Kharma loudspeakers. Each single step Kharma takes is further and further in-depth Kharma into the realm of bogusness. It is not that I find that “Kharma the Manufacturer” or “K...

[quote user="jessie.dazzle"] Your latest post got me thinking in a sort of incomplete way about how you might locate the injection channel... If you consider tone as a harmonic of the original source, then (depending on the order of harmonic) it may ...
