The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wouldn't call it an "open baf...

If the idea was to demonstrate the unbelievable fidelity of these speakers why wouldn't they use an instrument everyone had heard live or barring that bring in a set of taiko drums and let some taiko player have at it? It's hard to tell from an MP3 f...

They offer 24/88 downloadable and thanks God they do not record the Audiophile Blues or the similar crap. This is a good part. The bad part is that they record at 4X and then outsource the file to vireos industry cretins to “master” them, pushing...

I was asked a few days ago what I think about Zandèn new CD player and I replied that I do not think about it.
Truly, those companies produce new models each 18 month to initiate new rounds of cash extraction from clueless, deaf and blind audi...

[quote user="steverino"]FM is Analog Signal Processing vs DSP. The compression aspect is only really intrusive on orchestral works. Pop and jazz are already compressed and chamber music presents a more limited dynamic range if not limited contrast. B...

An amazing event took place during the flip between 2011 and
2012, the New Year nigh. It was my former suburb listening room, the one that
had the midbass horns built into the attic. At that time, I was running playback a lot and
I frequently was...

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

[quote user="Romy the Cat"]You absolutely incorrectly, in my view, look at the data. The files of cause do not have the same start mark. Why shell they? I did not subtract one from another. You did in phase the files and did the subtraction but what ...

[quote user="HookEm"]But, although it seems things are moving in a good direction, the overall presentation still seems a bit dry (not as fluid as my head tells me it should be).[/quote]HookEm, it was a bit is very generic comment that does not expre...

Ok, it is a lot of information on my plate and I am trying to make sense of it. Below I will share my observations about the new Pure Power 3000+.
The first thing first. In the post I made a few days back:

[quote user="haralanov"] So the tweeter is always needed. The bad thing is it deforms (in 99,9999999999999999999% of the cases) the perfectly round audio window, formed by the midrange channel and "pull" some notes sometimes at its axis. These are of...

My interests in sounds are lately gone to next direction. I became less care about the expressivity of sounds but rather about semi-masochistic subsiding of sound, almost at the level of sonic humiliation. I am taking about the state of intenti...

KM,
Very good points. There is one more moment that I would like to pay attention. The new prediction tubes are more powerful then vintage tubes. They all claim 1 extra watt because “better materials were used”. So, I wonder, if it would be possible...
