Use a ladder tye end of string put other end threw the horn you use for 1000Hz take off driver, measure front of driver to poll piece, that is were the diaphragm mounts to. add that to your measurement and that is were you put the tape. Then with the...

[quote user="Paul S"]Andy, I will say right away that I am not at all set up to "exploit" online music, but this comes across to me as "clean" and "noise free", with some nice spacial effects, basically devoid of harmonics, and not much in...

I've had lots of down time for a while now, and I just saw the old IEM (in-ear monitor/earbud) post while mining the site. I already posted that I got a Crane CC2E radio, mostly to listen to nighttime re-broadcasts of the local symphony orchestra. I ...

[quote user="Andy Simpson"] (2) Yes, in most recordings - which are unlistenable - multiple microphones are used in close proximity in order to artificially generate 'clarity'. The side effects (as you noted) are massively exagerated (but uncon...

[quote user="Andy Simpson"]Usually, this is a _time-domain_ artefact of microphone diaphragm resonance, made worse by excessive proximity. [/quote]
Very interesting!

First off, I will point out that neither Silbatone nor I claim or agree that the Aporia horn is a point source, because clearly it is not. The sound comes from two "areas" but even that is not a particularly useful notion.Although some do make that c...

I guess Thorsten is laughing since he should be the main receiver of TdP email. Popularity of a product is a double bladed sword. I do hope that sales of EAR 834 phono stage increased notably after Romy decided to make that circuit into his "end of ...

Hi Guy, [quote user="guy sergeant"]My experience with the 834p stemmed from having one at home for about a year soon after it was launched. I did try different types of ECC83 in it which did change it's balance slightly but not enough to make me like...

This is kind of an old topic which I noticed about fifteen years ago when I was beginning to be interested in stereo and I noticed that I did not like the typical stereo sound that was being sold to me. I am half-Japanese and I got interested i...

Yeah, and I once thought Krell was the way to go, a boy's (or a man's) dream when I saw pictures of the KSA 100 poweramp for the first time. I must admit that in 1991 I heard a demo with Krell KAS poweramps, Wilson WATT/Puppy's + Pow Wow subwoofer an...

Romy,reading your post a most recent listing consequence comes to mind, that I could also not quite place. I worked on a my cross-over, the RCL of my mid-range driver, and had a by-pass cap of 1uF connected over the 2nd base cap of 47uF on the one ch...

Hello, new to the forum... very glad to find it. I'm a sound guy at a small celtic/trad venue, I've had the opportunity to hear everything from Strads to FO Stanley's. I'm not professing to be an expert, I've just had the chance to listen to a good...

Facing similar issues, until confirmed or disproved by experimentation, the following represents my view:Situation 1):Mid-bass horns aimed generally TOWARD listener's ears: Alignment of the DIRECT OUTPUT of the horn for time arrival to listening poin...

Folks,Before we discuss "high distortion" amplifiers, lets us ask what kind of SPL Romy's system produces.I don't know, so let me make some eduacated, conservative guesses.Let us assume his midrange and treble Systems are both 100db/W/m and he listen...

Romy,
New member around here great website! I have what is probably a silly question about the above EAR schematic. I've been in the planning stages of scratch building a phono stage and have been looking at a few designs and ju...

It's polishing a turd though isn't it? I listened to the 834 quite a bit when it came out and thought it sounded poor, even for the price. imho, The circuit's just bad. If you do all that to it it isn't really an 834 anyway. I used to work for a valv...

[quote user="drdna"] So you do not recommend the stock tubes? Is it a specific change you recommend?[/quote]
Better tubes will certainly give you better sound, in many cases more sophisticated sound. I do not know what tubes EAR uses as stock tubes ...

Thorsten Loesch who came up with the mods, details what caps and why on the first page of this thread. Lacking interest for multiple years of auditioning caps, I just built it that way (2012 or so) and have had no urge to change anything. Romy has pi...
