I have come across this company mentioned in a preview on '6moons,' and the information on the company's website suggests that this is in theory really a complete solution, and one that makes sense even to the non-engineer that I am to...

[quote user="Paul S"]Joaco, all this will probably be moved back to the "Electricity" thread, which is not really an APS Forum, as it has appeared for a while, now.
Paul[/quote]Yes , I made a mistake ... it will be much better in the Electricity thr...

Hi Romy,[quote user="Romy the Cat"] I would discard the test disk truck– I never use it. Take a silent space between the cuts (test disk!) and make a needle at your operational VTF to be in stationary ay a bit more than a half record.In fact it is ar...

[quote user="Paul S"] I remembered a host of "old" drivers from my past (not old at the time...) that, if memory serves, sounded rather muffled and slow, with humped response[/quote]Yes, Paul, that's exactly the way they sound in their original condi...

[quote user="Romy the Cat"]Do you personally recognize the sonic impact of bad electricity in your own playback?[/quote]no, not in the sense that i assume you mean it. instead i have my own beef with bad electricity, which i suspect is different fro...

I think my new room and new midbass horn will give me an opportunity to play at the NEW LEVEL with a notion that I have been chasing for years. I am taking about perceptual shrinking of frequency response. I need to admit that most of the ugliest...

It is difficult to say below what frequency there is no sound registered, the lowest fundamental on a double bass is 41Hz and the A0 on a grand piano is 27Hz, both these fundamentals and at least one harmonic thereof would probably be recognizab...

I never tried the Onyx. I had an Urushi, then a Jade, and now a Coralstone. No I didn't buy any of them in the US so I paid a lot less than the crazy retail prices people throw around. I only know one person personally who did try an Onyx and he d...

Continuing my observation about the Timbres and Audio.From what I said above it is very important to understand that Timbres in Audio are not the photographic density of the colors themselves but rather an ability of a photograph to differentiate...

The throat diameter of 7" is what I first approximated as an acceptable size, with the 4" being an alternative (should some unwanted effects arise, I may then experiment with the 4" throat). I can't simply assume 7" will be correct (though that...

Okay so I got the NOS Sylvania "Spring Top" dual filament 2A3 tubes and have been listening to them for a while, now I am ready to make a report on the tube.
The tube is well built and structurally sound. Tapping gives a very small "tabla" sound ...

I am not a big fun of Dvorak 9th under Ancerl. I’m not big fun nether the orchestra’s balance nor the recording quality. Anyhow…
I do not think that that you need to worry PH-77’s accuracy of curves or the comfort to switch them. It looks lik...

[quote user="Romy the Cat"]Now how much better would be if people abandon that idiotic SACD/DSD and Mark Donahue would record BSO right in PCM at 88.2 kHz/24bit or 172.2 kHz/24bit format? Then the files that we get will be as close to raw master file...

The Multifaceted Random Dipoles – what the hell is it?
Well, this is what Eugenie’s uses, perhaps without realizing it. I do not know how Eugenie came to it. I presume that he was buying over the years the drivers on eBay and now he decided in...

[quote user="KLegind"]I am a big room buffoon. I like to see and hear a room and I like to walk around and "test" it. Sounds dumb but sometimes I can sit in a room and dream about what could be done to it in terms of Sound. It started around the ...

The BSO’s session was opened today, welcome back James Levine.
The concert was ridicules in a way. It stated early. The fist past was Glinka’s Ruslan and Ludmila Overture. The Overture was a nightmare. The dull and boring orchestra was juts re...

Scott, you see, this is the problem. You do not talk about the problems “as is”. All what I was asking was the acknowledgment/recognition/identification without context of loudspeakers. Your listening/assessment awareness is completely grounded to th...
