Ok, I have been experimenting with placement : Long wall versus short wall. Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor)...

[quote user="Paul S"]Well, you can count me among those who are perennially frustrated by all the unnessary stupidy that goes into most recordings, that's for sure, although I have several hundred records that I would like to keep for the p...

Actually the most interesting subject in physicality of ear to me is not the cochlea damping but the fact that brain and ear are liquid decoupled and whatever brain hears is transmitted through a liquid pressure wave. Of ...

As the life nowadays runs in a very different schedule then
it was years back I recently discovered a new invention of mankind – those little

Fascinating info. My first post here though been a lurker for years. @Amir I assume the info you posted above about PSU changes come from Silvio? It's quite fascinating so if there's any further info published I'd appreciate a link to it.

The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

I have heard vintage tannoy red (driven by 30w push pull EAR 861) and vintage tannoy gold (driven by 20w set ongaku japan). I think for 92db the 20w is not good idea.http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=3746#3746T...

Methinks that Mr C is correct in that the SPU cannot be deconstructed as I asked the same question elsewhere and got shouted down. :-( But hey, maybe they were minor league rookies and some major playa has the answer.... By the way ...

Perhaps I should have mentioned before that the K&K is another spin-off of the well-received Arthur Loesch RIAA network. Also, the K&K's gain scheme is based on "classic" microphone circuits. While I am not say...

Romy Hi, Raplh uses a 300b push pull, but the power supplies are massive, parts alone 15K Euros, each channel has a separate supply, the pre-amp again two massive power supplies , he prefers to use eight of the horn loaded bass bins, although I...

[quote user="thorsten"]Designers like Kondo San spend many hundred hours "voicing" their Amplifiers, allowing a blending of a variety of colorations together in such a way that the overall sonic impact is quite small. For many others (amateur or prof...

G10 also makes a nasty mess after you've cut it, get's all over the machine, fine "stuff" in the fluid... nasty to work with unless the end justifys the means. so it's fun to bitch @ anyone wanting to use it, that the only thing gain...

My other love and career has been as a metal sculpture so I like to mix the two. It gives me great pleasure to see cool looking audio while ensuring that it sounds a good as possible to my ear. Using 4 of these tubes in my next build, I would like ...

I had my visit in Munich yesterday and the Cessaro´s performance was totally different. Tonally without any compromize, so it was a pleasure to stay in the room this time :) Unfortunately very much on the muddy side. I think I start to understan...

Hello Romy,Just thought I'd post my latest re-visit to this cartridge.I've played with this overthe last 2 years on and off between Helikon/VDH MC10. It was ok but did not make a big deal,so I carried on with the Lyra which was finebut not what ...

A friend has a fixed headshell model S2 and is about to trade for a detachable just for convenience but worries if there is any extra sonic merit in the model he already has?Any idea Mr B____p.s. Romy, I've got my 901 and I'm very much impr...

hI bRIAN, [quote user="Brian Clark"]The 834P was a revelation for me, being a circuit that I would have dismissed as "old hat" (Feedback? 12AX7 cathode follower? Do me a favour!).[/quote] Me too, but you know me, i'm mainly pragmatic. The EAR 834P is...

I THINK I managed to macro position by ear from to your advice. I did the tango with my bookshelf speakers and listened for evenness and bloom in the 80-500Hz area (filtered out the rest with EQ).Yellow marks the first hot spot I found, and then went...

some months ago. It was posted at AA about a year ago or so. I keep the "solutions" if someone interested wants to know his scoring and how much of a "fundamentalist" or "overtonist" is.The only interesting thing about it is how being one or the othe...

[quote user="twogoodears"]Also: a tuning fork, the basic, humble tool which makes a full orchestra to play "in tune" is - as applied math and acoustic, a sort-of interpretation of Nature and its Laws - giving 440 cycles (hertz) flat to the trained mu...

Thank you, Jorge, for comment. I'm definitely going for wood horns. For my ear it has no coloration in compare with other material. Only for experiments I'm using what is available ready.Regarding driver for 300Hz, which one will you suggest to try ?...

[quote user="guy sergeant"]Isn't 330 ohms a little low as a plate load for an ECC83/12AX7 to be running into? 330K ohms perhaps?You often ask what is wrong with a given speaker installation, I thought you might be doing the same here. Keeping us on...

I am not sure what you say. You said that you are able to do time alignment by by-ear listening “a well known single instrument recordings, then to more complex and textured recordings”… Can you tell me what you are listing for while you are doing it...

Decoud, in order to say anything useful I would like to know to the following: 1) Where the tweeter will be installed? 2) What the size of the room? 3) What are you planning to install the speaker in your room? 4) What LF solution do you consider...

Anthony, congratulations on getting your project to this point! I mention without referring back to your schematics, I think you will be glad to have test points, along with variable resistors (trim pots) to re-set operating points, as needed, if on...

RomyIt's topical to ask, since I'm building a 4-way system at the moment ..( Tapped horn behind and three-way horn system in front )Do you favour the tweeter horn to be placed at the top, above the mid/HF horn , or in this situation place the tweeter...

KS, I am not following what is your problem is. The “big bass box” is unknown height. Let say that it is it 36” then it will have MF sitting about it. The lower midrange horn with 800hz crossover pint is sitting above MF. So, everything is fine as fa...
