I recently dealt with two manufactures that produce music . I noted that both of them stated with good result but nowadays, years in operation, they produce despicable crap. This correlates with a famous amplifier manufacturer, very much not stup...

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...

Further looking at where I would like to take the new 6-chennal version of the Super Milq I am contemplating a new revision of my bass channel output transformer. Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that b...

I spend quite a few hours playing with the new channel trying to ingrate into Macondo but so far not successful.
Since the new channel and the Macondo upperbass horn have identical sensitively and identical impedance I figured that I would drive it...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

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 ...

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...

Continuing my observation about the Timbres and Audio.From what I said above it is very important to understand that Timbres in Audio are not the photographic density of the colors themselves but rather an ability of a photograph to differentiate...

When I started with Analog there were only a few record Cleaning Machines avaialble, I bought a VPI 16.5 with my first turntable.
Now, with the analog revival the last 10 years much more units are available now.

[quote user="Romy the Cat"]I have to say, that I genially like the new 99.5. I do not have as perfect reception as I had with 97.9 with absolutely clear, no noise background. Still, thankfully the compression of the new 99.5 is very low and last ...

Well, it is hard to express my excitement about what the new FM99.5 All-Classical is turning into. It looks like the programming is settling down and my concerns about to become too popular turn out to be wrong. The programs are very good, the ...

[quote user="be"]The best driver I have heard is the TAD 4003.
It does not use the secondary resonance of the suspension, as described by Duke LeJeune above for the TAD 4001-4002, to extend the response towards 20 kHz, but has a natural roll off fro...

Romy,
Thanks for your comments.
When you write "...but the major question for me, if I were in your situation, what kind topology you will be using the lower bass channel and how you will be driving it."
I assume you are suggesting that the ...

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
63mH coil and 795uF cap ...

...we'll have to compromise somewhere. So, since it isn't the spkr's range, then it must be the amplifier. Forget the ML's 18W. We must have ~38-40, so let's say our machine is using a 45 / 211 / 610 /g70 type of tube.Also I don't suggest we conclude...

Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that drives them. With that kind ...

Welll, you still did not express yourself what are the sonic verdure of DHT from your point of view. You are not obligated I juts proposed you to do it if you feel that have any observations on the subject.

Romy and friends,
Reading about the sensitivity of your system to electrical power supply problems reminds me of the days when I used to make my own equipment as much for the learning experience as for the final result.
One of the mundane things I ...

Last nigh I spend a couple hours to listening this thing. Since the amp is done in design phase and the final parts are still in order I can not finish it and close up – it kind of frustrating… Still, it gives opportunities to listen it knowing that ...

This is kind if funny as I never thought that I will go this way. I kind of have a need for an amplifier. For a normal full range amplifiers that would be able to drive conventional speakers. I really can’t use the Super Melquiades as it has the live...

Paul,
Thanks for pitching the Johnson capacitors. They do not look “large enough” for me. I used in past the following caps:
