Contacted PurePower early 2017 and got a money-back guarantee to audition their PurePower+ 3000
Hooked up my Audio Research mono amps and powered on. With the first mono amp on, PurePower started to generate this loud buzz from...

Not that I want to divert my attention from my horn project, I'll admit I am curious. The horns are going to take some time, so I might be able to squeeze this in if it proves feasible.While some might scoff at such a thought, for many of us, digital...

As the writer of the above-referenced propaganda, I am pleased to once again tweak the whiskers of the cat.
First off, this is promotional material so what the heck do you expect? Every brochure offers a new benchmark in performance or it is not doi...

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...

[quote user="manisandher"]Romy, this is very interesting indeed. I'm assuming that the sonic difference between these two files is in line with the sonic difference you hear between bad and good 'electricity' days when you're just listening to music,...

what is audio ?
Audio is our reaction to sound , if there are audiophiles with different reactions then you may convince yourself Audio quality is relative to listener.
I think it is not true. The real quality exist itself .

I have 2nd order crossover both on the upper knee of the ob bass section and on the lower knee of the midbass section. My measurements show phase response and the summed spl is as good as it can get. Have you tried the direct servo technology or do y...

The more I looking and thinking about the pool of available idea and properties then more I come to a “ridicules” conclusion that I most likely will not find what I need and what I like. The point is that if I combine my requirement for not suspended...

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...

As I have mentioned previously I’m slowly in a process of assessing other opportunities for my Macondo, since the EV T350 driver it too soft to be paired with Vitavox S2. While I am doing it an old observation keep knocking in my head. A few years ag...

The carts from Fidelity Research were made until 1989. From what I know, the FR-7 series are different among with Impedance, Output and what kind of diamond cut they have. They last forever based on their internal construction and can be retipped qui...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo
2) Finalize the “End of Life" Phonostage:
3) ...

I have to say, this might be the "best" review by MM that I've read. Certainly it is more thoughtful and less hysterically fawning than usual. I agree that with a stock Jensen SUT (if, in fact, this is what he's done) Lamm might have gone too far w...

[quote user="rowuk"]Oleg has a lot of bad press in Germany for unkept promises and defaulting on delivery of product. Just keep an open mind next to the open ear. The best product only serves a purpose if it a) arrives and b) performs.I really like t...

first i should say i need more time to judge the Audiopax for some reasons but i try to share the first thing come to my mind after listening to Audiopax.
I should say i use Pure Power 3000+ , I mean i judge Audiopax when it is c...

Paul, what I am saying has nothing
to do with your Troels project but rather a psychological exercise to understand
what truly is going on. Also, I very much not knocking at your door with my
mental approach to audio objective am trying to demonst...

Romy,Yes, I measured my cartridge-tonearm combination with test disk. The resonant frequency was completely different compared to calculation with http://www.mh-audio.nl/MySystem/RF.asp.7 years ago, I tried Fidelity

So it sounds like you're considering a move...Romy wrote :"...As I understand you in the middle of your midbass horn project were forced (or whatever reasons were) to move to new house..." My old place would have been perfect for the large horns. T...

user="jackydai"]Romy, I’m disappointed to see you confront your own
belief just to win a debate. It is not my intention to convince you, but if

Understanding Line Array SystemsBy John Murray
Behind the buzz, there are a lot of factors at work in line arrays. An explanation and comparison of current models. This discussion can’t be contained in just a few paragraphs, so we must start with th...

[quote user="Paul S"]OK, Romy, that EnABL stuff got my attention!I can't recall all of the bad ideas borne of good research, but this EnABL thing sounds a little fishy, and certainly it sounds too good to be true, as existing in a simple and really u...

Horns are of course some kind of band pass filters with different kind of ripples at lover cutoff and beaming at upper cut off, according to horn type.Maybe it should be added that contributing to the horn sound idea, is that the...

Well, Brian, I do not think we here are in a competition whose way is more innovative, also the RX corrector do not use any air caps, and I do not know why you refer to them.
Unquestionably the idea to milk a transformer and to use its inductance to...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

For the sake of helpfullness, I think that we may separate the differences of the ported speaker designs of myself and Petar. What I have described is the standard, pedistrian model of a vented speaker. Petar's is a hybrid aperiodic-...

Scott,
Unfortunately Bruno Walter is not my guy, and particularly on Richard Strauss and therefore I would not help you. However, I would suggest you to find a different, more productive venue to research performances after those “just heard” exper...

[quote user="Paul S"]Scooter, many houses in the Northeast were roofed by people who understand how this works, and the first few courses of shingles are "underlain" accordingly, to preclude such seepage.
In Romy's case, I believe he could sim...
