Thanks, Jorge, but what you propose and what is done at the pictures your posted has nothing to do with Infinite baffle. This configuration rather reminds me the 4th order bandpass. It is popular setting but it is not what I like as the bass coming f...

Part of the reason we call our computers 'transports' is to encourage people to think of the number-crunching part of an audio system in the same already familiar terms as a CD player - because all the same things matter: CD transports vary according...

Romy,You maybe thinking of your a/c problem backwards.
In use, air conditioning vents become louder as the air speed and turbulence increase. Reducing the aperture of a vent can increase noise because a reduced aperture increases air flow spee...

Hello Haralanov,That's a nice strong heavy box you have there.You might want to check and add some more sand in the future because vibration helps the grains to adjust which in turn reduces volume.[quote user="Romy the Cat"]10) Do you know that you...

I just poked around on eBay and it seems the 6c33C-B tubes are not so easy to find. There are however plenty of the model 6S33S-V. My understanding is that this is supposed to be a more durable version, intended to...

[quote user="Romy the Cat"]David, I think you a bit overly glorify the notion of "precision instruments" that we all are a bit taken in high-end audio. If you go to a good hobby shop and by a microscope for 200 dollars, or lawn mower for $300, or a k...

[quote user="Romy the Cat"] Why do you feel that uniform "floating" rotation is possible only with N amount of drives? [/quote]I don't feel it's the only way :-)[quote user="Romy the Cat"]Let look in this deeper. A single drive would it be idlers o...

[quote user="Romy the Cat"]I do not know anything about Versa TT. I spoke with Tritium TT maker (about different subject) and he told me that various platter mass are available for his TT, including 100 pounds platter. Still, as mem916 point out: th...

Last 2-3 weeks I’ve been corresponding with a new reader of my site who sent me a few weeks back an email with a question:
“Romy, I read your comments about TTH and about “absolute tone”. Are you basically taking about timbres?”
That question made ...

Yes, this English pace did not give a lot of new information. I know nothing about the AudioTekne Company. I like that they wrote about their bass driver but I do not know how much truth and the actual results behind it. I do think that they wor...

I would contend that most of the microphonics and feedback in valves is usually caused by the resonances and vibrations of whatever they are plugged into. Glass is very rigid which is only enforced by the shape into which it is mol...

[quote user="Romy the Cat"]Stonily they are very similar in my view with a very slight advantage of 6E6P in delicacy and softness. I do not know what you mean “respond differently regarding vibration.”[/quote]As I had been looking at all these tubes...

Richard, here are a few comments of disagreement that might sound absurdish but I find them very.... indispensable.
The rules are always there and consequentially the data of the rules is always there. We might not have awareness - which particle o...

[quote user="tuga"]I somehow feel that you should look into the vibration induced resonances that those rooftop horns might create.
I'm not really familiar with the all-wood building techniques used in that side of the Atlantic but I have a hu...

[quote user="haralanov"]I think you wanted to say reflection surface, not radiation surface, right? Radiation surface is the surface that is directly attached to the vibration creating element (the voice coil). So the radiation surface of the horns u...

I would say that there are advancements where you would get far more unanimity on the progress that had been made than one would do for audio after the development of tape. I don't think anyone would want to go back to cylinders. So there are advance...

Paul, as you write the pendulum effect is unfortnately unavoidable if one wants the levelingfreedome of spikes, so I try to live with that. I looked at Walker...tjaa....$1750 for a record clamp...I also saw how he works on his suspension (look at my ...

[quote user="skushino"]ScottL,It looks like the two pics you posted are of different systems, the first being slot loaded PP, and the second (full-system) showing a "traditional" IB. You also seem to be confirming my intuitive hunch of potential sou...

My reference to air caps was purely a tongue-in-cheek reference to the voids in the coil. Of course the parasitic capacitance due to the propinquity of winding layers would dominate and here the dielectric is quite often Mylar.
It's just that the ...

[quote user="RF at Ona"] Congratulations on the construction and installation of your horns. May your pleasure at the results reward your effort and expense. I find their installed appearance even more geometrically striking than anticipated and I su...

Some of the DIY "Eastern European"/Slavic systems I "hear" on YouTube seem to have very amazing Tone on "selected cuts". Though this sound is not common, I have achieved and played with it myself, and it is "fragile" in the sense that it rarely (ve...

I thought the Forsell TT was called the AirForce. What happened to them? Are the descendants now called TechDas?
Maybe someone can clarify: what does a TT need to do other than provide freedom from vibration, a place for a tonea...

Audio people frequently go astray in their thinking and actions and this creates a good breeding ground for all possible audio sale opportunists. I would like to explore one moment that has not a lot of public attention and to look at the moment slig...

YE!Weeks ago I had a long thinking about it and posted the subject : primitive steps for standard soundI was thinking that how can we shape a standard idea to cover a primitive sound and how to standardize it .Well said romy we need these fields to ...

Jim,
I do not know if you still fighting with 7788 noise but let me tell you something: those Allnic shock-absorbing tube socket adapters are insultingly affective. I act lay made some measurements and I was VERY surprised how much the Absorb-GEL ea...

On any USA electrical wiring system, ALL circuits are referenced to and mechanically connected directly to a common ground at all times via the "neutral" wire, which ultimately connects to the grounded bus in the service box. And all UL electronics a...

Paul, thanks! I'm quite happy to hear I'm not the only one fighting vibrations in a seemingly dead structures...It takes a lot of thinking to properly isolate and damp vibrations.Not unlike in the complementary problem: reproduction of the audio rang...

Romy, I have a very large collection of 45 triodes.... many brands and varying internal construction. From my humble viewpoint, here's some personal findings on the various types:- Globe 45 tubes... these are the earliest, mostly from RCA. There are...
