Jarek, when you say disconnecting the phono ground from the PP ground stops the noise, why is it you don't just do that? Are we confusing "ground" and "neutral again? If the phono stage works quietly when its ground is disconnected, why don't you jus...

Hmmm...Whatever it is, if it's on the ground leg it "should" be possible to route it to ground before it gets in the amplifiers. Have you tried moving around a sheet of well grounded Mu metal, see if it catches and/or drops hum volume?Paul S...

Metal caps over phono stage unused RCA jacks can help with stray EMF/RFI. Cardas and others sell them.Not saying something is wrong with the PP, just saying it doesn't take much to get noise from a phono stage, including any change in ground potentia...

Glad to have known Clark, and always nice to reminisce. And I will mine that Best Performances List, for sure!Paul S...

Here's a decent attempt to boil down basic "ground" issues. Generally speaking, according to best practices, grounding one's hi-fi is a systematic attempt to equalize the ground potential throughout the system at "zero". Again, phono stages are harde...

Jarek, what you describe can happen if anything with voltage touches the chassis, or something might be arcing across a very narrow gap. I have seen part leads that went too far through PCBs, also carelessly fitted stand-off. Even the axis of a choke...

December Stereophile just got here, featuring MF review/promo of the new SAT XD1 DD TT. Setting aside the cost and the hyperbole, it actually seems to be something that could get the job done. A few years ago I was still waiting to hear a convincing ...

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...

I'm practically bursting from not talking about this! Did she write the last piece for the marimba? It's amazing how that instrument overpowers the recording equipment, which only serves to underline what she's talking about! What a gloriously ebulli...

while we are making other plans. I am pleased that you've wound up pleased. Let's hope this is typical of all the "setbacks" you're faced with.Dog photos draw happy lookers in droves.Best regards,Paul S...

Sounds like there’s more going on here than a dog… My
wife was never a physician, but she was a teacher, who became an artist, who
became… a dog breeder, about 20 years ago. We have lots of dogs around now,
including old ones, little Maltese. ...

The new battery got here and when I removed the charging and PS adapter harnesses from the old battery I noticed that the threaded positive post on the original battery is broken, inside the battery! I must have over tightened it after cleaning and r...

The original Odyssey PC625 battery I used for my DAC finally crapped out, a couple of months ago. This means it worked when I wanted it to for 12 1/2 years. Not bad, I think, and this even though it mostly just sat there, doing nothing, since I usual...

JJ, for me, the issue with Bruckner is that it does not often sound coherent to me, in terms of themes, phrasing, and structure. Rather, it often sound discursive to me. I have a copy of the 4th (comments in the Music section thread) that mostly make...
|
|
Anthony, congrats on your amazing progress! I know how hard it is to carve out time for this stuff! I see you are looking for gain from your pre-amp, which makes me wonder if you have been using the passive Placette, as opposed to the active unit, wh...

Thinking of this discussion I just revisited a "time-related" post I made years ago:http://www.goodsoundclub.com/Forums/ShowPost.aspx?PostID=9884Great work from Fritz Reiner, directing the RSO through Brahms' 4th Symphony, and perhaps worth a close l...

Thanks, Romy. Nice to stir up his presence. Perhaps the term "Renaissance Man" is used too often; but it certainly applies in Clark's case.Paul S...
|

Wow, I have been thinking of Clark lately, hoping he could steer clear of CoVid 19, and I mentioned to Mark just today that Clark visited me out here a couple of times, that he was very well educated, and he had some "unusual" ideas about tuning a so...

We had something like this discussion years ago regarding what makes for the best listening room. I "remember" opining then that I prefer what serves me best as a "whole person", and this remains true for me, even as my circumstances and sense of "wh...

With a nod (and existential apologies) to H-G Gadamer...If to take your stated objective (Techno "Music") seriously, it might well be that materializing your image of yourself in possession of the speakers you've shared could fulfill and even satisfy...

Just tossing in as possibilities the old JAN GE 5751s. I had a pair of these that were very interesting, including excellent, very even sound density and truly great LF. The only tubes in my system now are the old, "New York" 6922s in my phono stage,...

The "funny" thing is, the part that "sounds the best" in one situation might not do as well in another situation. A great example I can remember is the fabled Vishay S102 resistor at the grid. Great for stepped attenuators; not good at all at the gri...
|
|
Understood, and part of the reason I keep putting it in quotes. But much of hi-fi is "as if", isn't it? Getting back to harpsichord, for instance, it is amazing how noisy the instruments themselves are, yet one seldom hears/senses that via recordings...
|
|
Robin, your explication already includes a great sense of where you are and what you are after, and this should save you a lot of time. I like Romy's ideas as time savers, as well. On the hardware front, given what you say you are looking for, I thin...

Not sure of the cost of advertising in the "big audio journals", but it seems "the companies with money" are always trying to maximize return on investment, like any "good" business venture does. One popular strategy is to "get a name, then reel 'em ...
|
|
Funny, because, as far as I know, this site is the only place that deals with hi-fi in terms of developing sound from a personal perspective. While the book format is a nice way to present information, wouldn't it be nice if the contents were derived...

One thing I have noticed is that most of the effort for many years has gone to "marketing", and "they" have gotten better at it with the passage of time, at least broadly speaking. At that same time the size of "The Audience" has grown it has also be...
|

Of course you can do it all by ear, and I found that there were times when "my ears disagreed with the meter". As you note, signal strength and "quality" also relate to "mode" (such as Multipath), and not only broadcasts but also tuners vary as to wh...
|
|
A lot I know, I gave up on serious FM decades ago because I just haven't had acceptable access to good programming or broadcasting. Still, I remember the fiddling I used to do trying to polish the gain/selectivity equation. When and how attenuation i...
