[quote user="floobydust"] One of the reasons I no longer use a tube tester. They make a measurement at a specific target operating point(s). You don't really know what it is, so what are the chances they will be close to your actual circuit opera...

Romy, On a past thread you adviced the following regarding the connection of the PM2:"You will not have problems to drive with balanced Pacific your
single-ended amp. Juts buy a good quality XLR to RCA adapter or order
XLR to RCA cable and you wi...

[quote user="KOTriode"] Without regulation, this amp would not work correctly due to its design: DC coupled and fixed bias. The high transconductance will make the bias current varied as much as 50-100ma due power line fluctuation without the reg...

A few days back Simon
Rattle brought but Berlin Philharmonic in Boston and blew my mind. I never was
a huge fun of Simon Rattle and the music was garbage (Mahler 7). We were
sitting accidently very close (Berlin extended the stage consuming the fi...

Jessie,
I was trying to evaluate the gain of my amplification in respect to larger room and again was thinking about your case. I think something that you do it not correct. You are complaining that you have not enough gain in upperbass, but I...

[quote user="speedysteve"]Well, I think
it is horses for courses and the tapped horns are a bit of a different
gigi. I found it is imperative to suffocate the
rubbish that is coming out of tapped horns above say 100Hz - mine are sized to

Iraschwips, I do not think that it has anything
to do with impedance at all. You might have sub 1R impedance of your
loudspeakers and perfectly compensate it by wiring a custom transformer that
will perfectly work against lower impedances. I would...

[quote user="peter foster"] By "dynamic viscosity" do you mean the reluctance of an amplifier to be dynamic, i.e., the degree to which an amplifier sounds like it is bogged down, usually as a result of a poor rise time on transients, i.e., poor HF re...

Hi Dima,Thanks for your comments; please forgive the chaos of what follows as I have to rush!
Agreed on all counts - the dc bias point would need adjustment and monitoring; I supposse it depends on how stable the electricity is from the wall; anothe...

[quote user="Telstar"] Oh I was thinking about FLAC, such as the ones from Linn Records, not raw WAVE files. [/quote]
I use only WAVE64 (.w64) files,

I just received PS Audio June Newsletter and have written a reply in a format of an open personal letter to Paul McGowan. Below is the text.
Paul,
A new round of my experiments with curing electricity made me to write up this open letter. I did not...

This thread has been pretty interesting overall. I've read most of it and would at least like to provide some feedback on the technical side of designing with the 45 and 2A3 DHTs... at least from my personal experience. A few years back I decid...

[quote user="Romy the Cat"] Oh, good, why did not you tall it before. How the hell can
you listen if it you DAC outputs 1V?! No wonder you have no volume. Also if you
have no voluble you do not “get” one of the most advanced feature of multi-amp ...

I have to tell you something: I do not believe to audio people. Whatever they say has some freakish twist of desire to present the sings in a certain way instead of witnessing and experiencing the thighs as they are. This is one of the reasons why I ...

Anthony, I am not so thrill
that you are unlashing your into this direction. Not that it is my business and
you can do whatever you want. Still, I feel that methodologically it is not right
way to build a playback. What I mean is that to evaluate ...

user="devo_yan"]I should use at least 2 amplifiers (one for high

Yes, you might, though I

[quote user="tuga"]Have you considered
"fencing" your equipment bay?
Such a baby-proof fence might actually be made to look nice (more so in a large
room such as yours) and you wouldn't have to reposition all your equipment and
cables...again.[/q...

I was searching for an answer why squire wave is so screwed and I was advised by the site’s visitors that it is due to HF restriction of my channel. My HF response does look too low to me – the 23kHz; with all my ultra low capacitance magnetic I ...

Spent great time and with happy with result. Not the results
are so spectacularly good but the playback is back to be operational that I was
missing for a while.
Starting with films. The damn OPPO has not enough output for
my Milq. I decided to...

As I said above your you "experienced today with GOTO" is just your transitional
feeling and you will change this feeling many times. To accommodate a pair of 42Hz
horn in a system is a year-long project otherwise you get an accidental result.

[quote user="Romy the Cat"] That is very good approach in my view. The
problem is in this approach that you have to have high sensitively speakers
that you would be able to use with that test full-range Milq. The behavior of
the Full range Milq wi...

It was somewhere in 1998-99 I believe. A local dealer, Dan
