After much listening and measuring I convinced myself that there is no way for me to escape the use of the 24dB per octave slope if I want to keep the sound of my midbass horn not violated. I also have to admit that I will not be able to render 4th ...

[quote user="Gregm"] It's better than a Marten Supreme because the mid is cut off @500Hz whereas Marten cuts it off at 1,3kHz "where the ear is at its most sensitive". Note: they must be referring to latest technology ears -- not the tradi...

Yes indeed. The company was originally Nova Physics and appears to have been sold on to Sam Laufer, a lawyer by profession originally who brought in Mark Porzilli of Melos and Pipedreams fame. I do not know if this company actually manufactures or se...

[quote user="decoud"]Yes, it is built according to the schematic, but by someone else, from whom I have only just received it. The opt is custom-made nanocrystalline amorphous core, gapped at 300mA and running 200V/240mA. [/quote]Very good. The 200V/...

Dear AllI am new here, but have been reading quite a bit about the EAR834P from people here who are quite enthusiastic about this design.Thorsten had got me off my butt to build a EAR834P from scratch when he posted his mods at the AA. I still o...

[quote user="guy sergeant"]I used to work for a valve amp making company and we had a little 2 stage phono amp that sounded far better than the 834 with passive eq, no feedback etc. It also cost less than the EAR.I can send you the schematic if you w...

Romy, how are things progressing with this? Is it all done and dusted yet?
Can you compare and contrast the sonic differences between this high Gm contrivance and your previous EAR 834 variant?
All the World is waiting for the sunrise....

Much clearer with the drawings; thanks again, Romy. So, if I listen to my old jazz LPs recorded live at The Village Gate with the DSP-Z9 on that setting I would be getting a double dose of ambience, along with the extra stuff the recording engineers ...

Yes, Thorsten was the man
that made the initial modification in the EAR 834 and I need to note that it
was not redesign of any kind but juts basic modifications and admitting the unnecessary
things. Even though Thorsten is the industry p...

[quote user="Romy the Cat"]He use Magico monitors and with 91dB sensitivity and 4R impedance I would be very surprised it I see any SETs in there. It even more interesting that his Magico speakers are sitting right next to the wall. I do know how Mag...

In considering integration of my own mid-bass horns, and how I'd ideally like to do it, I too passed by the underground, up-firing solution, and very much like this approach. I do however have a preference for inverting the concept, resulting in a do...

Romy,let me step up to the plate and get shot in the foot or what ever. A lot of what you relate is of course right - BUT, 'where the is smoke - there is a fire" as the saying goes.So, there must be a reason for this 'abnormal' notice of honking horn...

Very interesting about the lateral vs. vertical resolution. According to "Raptor Force", a 2007 Nature documentary, the owl can locate a vole under the snow based on its offset ear geometry. "Like us, the owl can find the left-right position of a no...

[quote user="Winnie"]Firstly let me say that I believe musicians could be just about the most important people to judge the quality of Hi Fi. They know how the music sounds during creation so can best judge if that quality has been preserved (less de...

hi RomyI agree with the technical design issues. Though i experienced that for most modest domestic dynamics first order xover can work surprisingly acceptable.Also agree with bad impression of exhibition experiences are steered by many factors and s...

Was invited over to Romy's today. Spent two hours going through recordings. First, I hear differently from him. At my age,76, I had a hearing test that showed oversensitivity in the 1000 to 6000 hZ range, and quick drop off above 10,000 Hz.Second, I ...

Hi Romy, It's called "the itch". I was debating high and low before plunging for the Pass. I played around with the capacitance setting. I put it to ZERO and the sound lacked body. 100pf was a little better. Bass was tight but lacked absolute weight....

[quote user="drdna"] Oh, I see you are absolutely correct. I am very puzzled. As it says on the website, the mastering studios relocated to a new location. Maybe there was no room for the old set-up. I was only in the old studio a few years ago. I sw...

Hmmm. It seems like many people have difficult-to-adjust tonearms, which does take the fun out of fine tuning. And overhang/tangency is always a PITA, in any case. But I always thought that the final tweaking is done by ear. I do start with the...

The fact is, typical "stereo" L and R separation is mostly an engineering hodge-podge to begin with, and any further messing with it will be very much settled by ear, whether at line or at speaker level. Yet James Bongiorno set out to "solve" the pr...

Adrian, is the room raised floor or a slab? If the former, then wall-mount makes sense, especially for a TT. If slab, then you have more options, as far as spreading things around. Soft carpet or hard flooring factors, too. Yo...

Yes, that WAS a common connector but this won't help you now. Radio Shack sold those as recently as ten years ago.Since the female side of the connectors has spring terminals there is some variability permitted in the diameter of the male contacts. I...

Why did I drag this out for so long? The WT Reference arm I use has easily adjustable VTA, and for some time I suffered using a loose L-shaped Allen wrench for adjustments, with no way to keep track of how high the arm was set. Although t...

Adrian, I wonder how you wound up with the never-mentioned FET 10? FWIW, it was one of the better all around phono stages I've heard, and - not that it matters - I prefer it to the EAR 834 I heard. Is this another case wher...

input grid, the hum has gone.Than, I did next changes:1. Twisted wire from input RCA to step-up transformers. Connect transformers input & output ground directly (not thought ground ...

I was just cruising the site, mining it for information (as I often do), when I ran across this "orphaned" thread with the "dangling" posts at the end. I suppose it's time to update this thread and in so doing close the book on it.Since I wrote the ...
