[quote user="drdna"]The question in my mind Romy is: why? I will be interested to hear your comment on what your goal was to learn about your system in introducing these and what the results are. After the extent to which you have describ...

I do not know it is just Triamp or 3-chenal DSET by the direction is good. The amp was mentioned by Twogoodears on his blog.

I do not know what he mention abou...

[quote user="drdna"]I was really shocked when I saw this idea of yours. It is a trade off of course with improved control over narrower frequncy bands being traded for axial symmetry. Yet because the position of the drivers is so very imp...

Floobydust,
excellent points as usually. I am not too concerned about the AC noise on my filament, at least at this point. I want to get the right “check and balance” operation of the whole amp (all channels together) and then will see how the...

I am in minor scale mode toady and play mostly chamber music and only records. FM broadcasts with all their majesty are hardly objective tool to assess what doing on with audio. So, I play records and tapes. Besides everything I am trying to figu...

[quote user="guy sergeant"] I've usually found valve rectifiers to sound preferable. [/quote]
For HF channels only. Still with shaft switch diodes and properly implemented input choke filters there is not advantages of tube rectification, quite oppo...

Now that the preliminary excitement of my ingenious idea wore off, I'm ready to share it and accept the harsh reality of any shortcomings... but seriously.
For a while now, I've been been working on optimally integrating my 3 channel...

[quote user="noviygera"] I want to listen to both 12db/octave and 6db/octave passive versions and see which one sounds better. And keep the one that sounds better. [/quote]Herman,
It depends what you would like to listen. If you would like to ...

For a casual observer it might appear that I am constantly fought with my ULF, finding and loosing better and worse configurations. It might be so but I have a very strong sense of objective of what I would like to accomplish. I want to reinstat...

Paul S says Still, who knows what sort of problems would yet get to the hi-fi via such a line.You raise a very interesting point. If the grid line were known pure than it would be highly likely that a consistent and significant benefit woul...

Horns are of course some kind of band pass filters with different kind of ripples at lover cutoff and beaming at upper cut off, according to horn type.Maybe it should be added that contributing to the horn sound idea, is that the...

To answer Romy's questions :
Drivers :
Vitavox AK151
Resonant frequency :
I did not try to measure it....

Romy,
Thanks again for your comments.
The RTA and filter mods over the past few days have driven me straight up to the local café to chill out; they have WiFi here (this being France, still no internet at the house)... I will be brief.

After going through the anal pains of the Image Gallery upload (it is sohuge now that my browser slows down 10000x times loading it and it ocasionally kicksmy router out of this world; can we do something about it?), here are some picsof my assault o...

[quote user="de charlus"]Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far fro...

While I, waken up by Mani’s idea to us MP as the only DAC, was playing with new Pacific I have researched deeper the HDCD subject in the BSO recordings. Mark Donahu, from AudioMirror with his slightly patronizing attitude might consider himself a...

I keep thinking about the strangeness of my phase inversion.
I still do not think that it should be this way. My leading explanation is because
I did not implement the crossover precise. If the crossover called for let way

Perrew,
I do not know if you use sarcasm in there but Lamm LP2 is not my bellowed phonostage. In fact I am one of the very few people whop do not like it at all. How much in what I do not like in Lamm LP2’s MM section come from the WE417 tubes...

If to look at the Melquiades schematic in the channel “A” you will see 78H first order low pass filter.

The low-pass filter in Milq and the low-pass filters generally is great...

Looking at psu LCLC filters is another subject , i have no idea about that but i have heard good PSU has more simple filtering with lower capacitance bank.
Generally speaking Simple circuits have advantages over complex circuits most of the ti...

Well, this concept of Defense Mode is good for superficial explanation (or for selling to ourselves own justifications) and I use to use it in past but I do not use it for a few years as unfortunately it is not what it is. The correction of “the wron...

I separated my two of my PP2000 in my rack with 3 feet space and run everything from one PP2000 and both Milq power amps from another PP2000. I also routed the incoming power cords that that are far from each other and far from outcoming power co...

Well,
The most miserable things about electricity that you never know what to do. I had in past different filters and mny imaginable power gismos, a number of isolated transformers, balanced transformers, regenerators…
For a couple years I was runn...

I wrote in “My Playback” section:
"Power-wise, I have 3 dedicated 20A 8ga lines, separate for my amplification, analog and digital chains. I do not use any power devices: filters, conditioners, regenerators, or isolation transformers – none of them ...

Not completely objective but still “some kind of test” for the bit’s resolution. For those of us who use Pacific Microsonics processors it is easy to see of the file was original. When pacific does A/D it injects the HDCD code. It does it in any ...

Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers and drive your ULF amp w...

Paul, it has nothing to do with noise reduction devices. It has also very little to do with the media on which the recording took place – would it be LF, tape or digital file. Audio it is about expression of musical spirituality through the semi-barb...

yap. the Olympian uses 70-500-5000-15000 cycles XO.
While the Palladian shifts to 70-400-5000-15000 cycles. (mainly due to cost saving on the AK151 phaseplug-design)
They use 6th order LR filters in the lows, 2nd order in the ...

[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...
