[quote user="dazzdax"] what is your experience with passive transformer based preamps? Is this the ultimate way to get a perfect variable gain? Or do you prefer to use an active preamp?[/quote]Chris,

I do not think so. There is no such a sing as optimal generic DSET but there is a concept of optimal DSET for a given situation. So what I think would be nice if some kind of company come up with a Reconfigurable DSET . The Reconfigurable DSET, or RD...

[quote user="Paul S"] Romy, on Fundamentals channel did you leave the 20uF cap at speaker level or did you re-configure that band pass at line level? [/quote]

[quote user="KOTriode"]Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from b...

user="anthony"]Hi Romy,
So it is time to think about the bass output
transformer in my DSET. My bass channel will be 8 x 25W/8565-00 each side
set in a sealed box and will cover the frequency range below say 100Hz.
These drivers can be ...

Jessie, 45Hz horn with 6”-7” throat around AK151 driver is from my perspective is the best thing might be theoretically built around a cone driver. I really envy of you and if I had room I would unquestionably go for it; this is why I keep a pair of ...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

[quote user="ulf"] Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than we desired. [/quote]

Ronnie,
I’m sorry I was not able to detect the clipping you were taking about listening your file. However, if you can hear ANYTHING distorted at 1kHz (when ONLY your upper bass horn is playing) then you might consider the following: it has NOTHING ...

E-v-e-n-t-u-a-l-l-y!!! Eventually the new “fundamentals channel” horn sounds as it should being incorporated in my Macondo! The key was the second order. I really never drove compression drivers to their 500Hz as I always used upperbass h...

You decided to go with mA or are they mV against 1R resistors?
I prefer the second approach personally and I feel that I can moderate the quality
of resistor and I can’t moderate the quality of the milliampere meter coil.

Well, they technically not Lpads but juts regular attenuators
even though they connected in “protective mode”. You can go with stabilized impedance
to maintain the high pass filter over the coupling capacitor to work properly
but I do not feel it ...
