Romy, I am pleased but not surprised to hear that you have quietly ascertained and begun to implement corrective measures to ensure the overall balance of critical elements in your new situation, since without these in place, you would likely come to...

Romy, all this seems to be fairly typical of large-ish listening rooms, along with grotesque lobing and combing. I agree with waiting to use absorbtive treatments until you have a sense of the the system/room's total energy potential, using current ...

Andrew, the "holographic imaging" reminds me of certain FFT "scans". You use the term, "SONAR". Surely, test tones are actually in the "working" audio band? What frequencies are involved? Can you say a bit more about generation and "reception" with...

Hi, WojtekI get lots of PM from readers of this site; it should work. Try again, and be careful with the spelling, etc. Though I can easily upload pictures to GSC Image Gallery, I can't seem to get them from the Gallery to the Board. Perhaps they ...

N-Set, I believe Romy posted scope traces of his PP output in this thread, many years ago. As I recall, it was a "pulsed sine wave". Nobody has said the PP is quiet; quite the opposite. As for battery power, I finally got to "A/B" a large, well thoug...

A year or so ago (I do not know exactly when it started as I but audio publication irregularly) I have see that Wilson Audio begin to advertise their new loudspeakers as the design inspired by David Wilson’s revelation after he was sitting at...

But how does that work with tiny amps? Is this a case where the thing is used solo, as "FR", or something, or is it part of a starts-at-89dB multi-driver speaker? I had some Rogers LS35As a long time ago, and they were fun for a while, ne...

[quote user="drdna"]What is revealing is that the system functions poorly with recordings with a lot of reverb. This is what one would expect of course, given the setup. Probably the best recordings to play on such as system would be the old Three Bl...

well fine, my X350.5 does 50 watt class A, and of course in push-pull. I use it with 120 watt max rated 3 way speakers of about 87 dB efficiency. You can see on the 350.5's centre instrument dial if you go out of class A. If I go out, I usually fear...

Amir. for me. regardless of what I've started out to do in audio, I have been forced to compromise along the way. I am sharing my speaker/amp compromises in this thread. My "second system" is a radio (or computer) and headphones (or "desk speakers")....

Excellent points about the A2, and especially the possible result of a "swinging" capacitor, if this is, indeed, how the stage works. I cannot offhand think of a single gain stage where a coupling cap is used just like this, but at those values, and...

Ha! You're either old or you read too much. There was also Arnie Nudell. Back to Bob Fulton, he never made 2 "statement" speakers alike! I actually owned E modulars from him. They were +/- the same as the Js, but with smaller subs. Ironically (cons...

Hi Romy,
Give the ribbons a try http://www.e-speakers.com/products/beengineering.html. These are too expensive I think but believe me the sensitivity is real. The best part is also that the impedance is very flat and an easy amplifier l...

Why do you care what Robert Harley, TAS or the people from Magico have to say?Why does it matter whether the reputation of horn loaded loudspeakers gets sullied in some way by these people? No manufacturer that I know of does it properly anyway. The ...

Serge, it is a common misconception that the old Altec cinema/PA systems were lovingly built and installed with tubes or high-fidelity "music playback" in mind. In fact, they were meant to be LOUD and durable sound reinforcement tools, while maintai...

I don't suppose the input tube was a 437A?And perhaps (at that price) silver trannies? I have never never knowingly heard silver trannies (apart from my Ortofon step-up), and I wonder why anyone would pay that much for them when amorphous ...

There were few exchanges in Lamm’s thread with Mike from Audio Federation referred here:

user="jeff1225"]Romy,When you say that the Vitavox 15" was the

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...

Chris, I'm not Romy but I've listened to some of their products -- about which I'll talk later. First:[quote user="dazzdax"]Hi Roman, FM Acoustics amplifiers from Switserland have been regarded by many audiophiles (mostly the ones with lots of money)...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

Hello Haralanov,It is hard to talk about sound, and define points: this is why the post is so long.Most systems I have lisitened to that measure a flat response have exagerated high frequencies and usually the midbass is a little shy, this might be ...

As a weekend-only listener, it can take me eons to break in some of my most stubborn components. In the case of the K&K, things seem to have reached +/- tonic equalibrium.I may have have mentioned it in passing, but at some point ...

[quote user="el`Ol"]But when the frequency where the dipole acoustic short circuit "kicks in" is clearly below the Fs of the driver, everything "dipoly" that can happen are rear wall reflections with the wrong phase, and that danger is also reduced b...

Wojtek, I am indeed hemmed in by the fricking electricity these days, to the extent that it is about impossible to hold on to a baseline for reference. And the Lowthers only make the problem more apparent.Yes, I still wonder about how I wo...

Of course this is basically propaganda. Who argues otherwise? However, I have found that it is possible at times to glean a modicum of useful information from "reviews" like this via a careful reading of what is said and somtimes via...

Why use the GM70 apart from its power potential? For one thing, it seems to require literally lethal voltages to become remotely listenable. Is it really "that" linear, to insist on it?But my experience with GM70 is quite imited. I ...
