Romy, I imagine it is irrelevant but have you found a difference between lower and higher voltage versions of the Electocube 950 series in the coupling capacitor position in the full range Melq? I ask because a stock of 1000V has become available at ...

The odd thing about the paper is that they do not try to show their initial design could actually be better than the commercial offering. They could have improved the measurement of their device or else exposed the Sennheiser diaphragm and measured i...

Thanks, Romy: yes I was worried about infrared too. One option might be to use something like HEUCODUR IR Black paint, which is black in the visual spectrum but reflective in the near infra-red. I'll see if the company that makes it will send me a sa...

I know it is a trivial point, but I dislike the whiteness of valve sockets. Since neither teflon nor ceramic is easily painted I have mine covered in black nomex fabric. This is no good for the 6c33c, of course, as it needs all the breathing spac...

For what it is worth, I use this for LEDs:http://www.vellemanprojects.eu/products/view/?country=be&lang=en&id=379858...but I have found no need for a fan or an hour meter, either of which would require something more elaborate. ...

I suppose something like this, but attractively sculpted, and without the vertical partitions, could be an interesting omnidirectional horn to put in a garden. Rather like a mobile sculpture, but with its dynamics in the auditory range. It would cert...

I do not know any interesting playback installations in London but I do know where to drink and dine near the Albert Hall, as I live ten minutes walk away: let me know if you need suggestions.
Kevin from Definitive Audio is c...

The interior of a forest would be a wonderful environment, it is true, but I wonder if a smaller envelope of greenery could have something of that effect: the key it seems to me is the synthesis of echo absorption and a subtle, shifting, organic nois...

The idea is that just as you might have a seat in your garden that captures a particularly attractive perspective on it, so you have a point where such a view can be combined with audio playback. That gardens are rarely silent and often dynamic (tre...

Outdoor performances always seem to me to fall short of indoor ones, and there are plenty of reasons why this should be so, but there is something attractive about a horn installation in a garden...it ought really to be made of rock, of course, f...

I suppose the richness of the musical language is a hint, but it can only ever be a hint, for taste is measured by preference not someone's justification of a preference. The same seems to me to be true of visual art and literature: criticism here is...

It is good to see PurePower here, and perhaps their representative could clarify how, if at all, their units differ *topologically* from a standard double conversion UPS device. What information the website has shows no significant difference in topo...
|
|
Yes, "nothing special" is exactly right, and cheap - £500 delivered in the UK. But the point is that there can be very little that is special about such devices, *other* than what these people talk about, which is audible noise from fans and ironware...

Some very sensible-sounding people have produced this:http://www.powerinspired.com/ag-series-ac-power-regenerator/They do not pretend that it is anything more than a double conversion ups with quieter cooling, possibly less magnetostriction-induced n...

The point is that spatial separation is not necessary in music in the way it is necessary for visual representation. A single musical instrument is -- more or less -- a point source, and it need be no less expressive for that, including in relation t...
|
|
Is it not strange that we are so fixated on spatial separation in sound? Instruments in an orchestra are spatially separated because you can't have one musician sitting in another's lap, not because the music demands it. Music is intrinsically time- ...

N-set, if we are at the level of worrying about solder, does it not make sense to drop RCA connectors, and their inherently village design, and switch to something better specified like BNC? Is this not otherwise a little like talking about having a ...

It is worth making the point that new technology such as Lithium iron phosphate batteries has changed the game when it comes to running digital. These things have no memory, do not suffer from staying charged, and have really very acceptable energy d...

I have to say there is hardly a production of Wagner these days that is not fucked up in some way, as if the only people who dare stage him are so narcissistic they will not let him compete with them, and need to try to handicap his power. Covent Ga...

Sure, I speak of amplification here because that is what we are talking about, but naturally playback is playback, not any of its elements taken alone.I am not sure more detail about the entire system is helpful because no amount of detail is really ...
|
|
It was the dismal failure of conventional playback to reproduce Wagner that first drew me in this direction; had I listened only to chamber music I might not have made the effort. Which is I suspect partly why other amplifiers are not like this: ther...
|
|
Strangely, no one but its architect has written here about the sound of the full range Melquiades, and so I thought I would say something with the benefit of several months of listening to a version of it. I say a version because though the...

The only advantage your pilot could have over Macondo is omnidirectionality, no? So why not suspend from the ceiling something like this: ...
|
|
Perhaps you should use the cathedral configuration to make a synergy horn of the entire ceiling: tweeter at the apex, mf a little further down each wall, and bass at the base. Were it steeper it could actually work. ...

The idea that there is a comprehensive objective measurement in playback is surely as absurd as the idea that there is a comprehensive objective measurement in female attractiveness. Sure, it is unlikely you'd find a girl hot if her BMI is >25 but...

They chase numbers because numbers is the only thing you can unambiguously compare. The model for evaluating feedback equipment ought to be musical instruments: that it is not perhaps tells us that most of the time audio equipment is not used to repr...

...for your (U)LF. They allegedly go down to 1Hz...Pass's SIT-1, however, seems as close to your philosophy as any SS device can get, being "D-SETable" though Pass does not advocate its use in that way....

Page 2 of the pdf you link to has four 2.0uf 950 caps: the writing is legible. So if anyone opens his unit and finds 935, well, it is an open and shut case......

I suppose at least you can give him credit for reversing the switch from electrocube 935s back to your favourite 950s.......
