First of all thanks to all who assist me with this project, including those who did not post here.

A lot of people ask me about those drivers and I’ll try to compile my vision about them. I did try most of the possible tweeters: dome tweeters with cloth cones, varies type of hard metal domes, compression drivers with aluminum, titanium, phenolic a...

Hi Thorsten,
Interesting preamp ideas.
The Silvaweld is also using some rather interesting ideas. For
example, the power supply is all tube (ie. rectrifier and regulator)
with a large choke as well for filtering and using a 300b as the hi...

A New Bridge to Old RussiaBy Heuwell Tircuit

[quote user="Lx_"] The second sentence is my own conclusion. It was not my intention to imply that it is yours, sorry for the misunderstanding this may have caused. We both agree that PP can be sensitive to incoming AC. The context and circumstan...

I was trying to strategize what would I do it tomorrow someone get in touch with me and offer my $50K. In another words what would I do to convert the Altec 19 to Cetla Ledom?This is an interesting discussion itself as it gives a blueprint for me...

As Tony points out, there are some digital cards with supposedly good
converters in them. The Lynx Studio LynxTwo or Lynx L22 cards are
said to work well. But the computer IS a very noisy environment, and
the idea of converters in it scares ...

user="kodomo"] Just a reminder about the room acoustics. You are
talking about bass frequencies which are as dependent to the room as the

Well, another page of my saga with APS regenerator is turned. I got the updated APS unit. It kind of “works” as I redefined the definition of word “works”. Under normal circumstances I would walk away from it but there are some moments in my “bad ele...

Similar to the famous sexist tail that women can be only ether pretty or smart the midbass horns unfortunately behave in the very same way: they can be only nicely placed in a room or they can sound good. You want the horn to place in a specific ...

Rowuk, a couple of corrections, but I am certainly not arguing. First, the dac outputs 1.25VRMS, or thereabouts...I am going to measure it. The 0.6VRMS is because I run it at -6dB into the Placette because for some strange reason it sound...

[quote user="jessie.dazzle"] I live where FM program quality justifies a good tuner. Despite getting what I consider to be really excellent sound from this modded TU9900, I will one day compare it to a TU-X1. I will post my findings here.[/quote]

in the common sense range for each horn/driver they have far LESS

Will try to answer all questions here.Romy: I understand why you do not wish to use the term “surround sound”, but it is the accepted term for what we are discussing. You may add other terminology, but it only muddies the debate until others accept i...

Ethan,
Since I published the article “Preamplifiers: keys to mystery” I received many emails from my site visitors asking about Lamm prams and questioning my remarks in comparing what I said to “data form other sources”. Some people disagreed or sur...

Thanks for the kind words Romy. I am enjoying taking my time with this project and getting things just right. It sure helps when there is little development involved, just duplication more or less. Development may come later as I impose my exp...

Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
