[quote user="guy sergeant"]I must have skipped the lecture on the emotions of materials when I did my engineering degree...seriously though,I can understand the concept of impedance matching materials, I can see that different materials would have di...

My journey with computer audio offers me reason to be optimistic. I think it is like everything else in the audio chain. Everything counts. Keep it as simple as possible. The power for every consumer is important. Keep the number of parts and transfo...

Interesting timing for this question: just today the Radio of Amsterdam broadcasted their version of La Mer and had some thoughts about it, primary in audio contexts…. The Debussy’s La Mer is one of the “lucky” pleases of music and it is well perform...

The oil I use has a viscosity of about 30-31 and I have used it for years with no problems. I have tried about six different viscosity oils and grease and the best results were with in the range I specified for (sound as well as mechanically), please...

David, that is funny that you are stressing my SX8000 or even mention it, if you ever invest the effort to read the site, or at least the thread then you would understand how out of context your manner. The AF1/Micro is kind of irrelevant, this threa...

I see Tech Das launched a new baby TT at Munich. The Air Force 3 looks more like a Micro than the other two. While not built on quite the same scale it still features an air bearing and actually looks prettier, for what that's worth, than the other t...

[quote user="jam"] (maybe another RX-5000 as a
flywheel might work?) If not set up correctly(which can be a pain) it can cause
problems. [/quote]
In my case use the RX-5000 as a flywheel did not work. I
mean it “worked” well from mechanical per...

Well, Doug
My attraction to HD Radio statred from the moment when I learned that my WGBH does one less step of analog compression for DH1 compare to FM and do not use limiting-out at HD2 for live-to-tape recordings. Very promising, isn’t it?&n...

[quote user="Romy the Cat"]To my surprise, pleasure and horror they all turned out to be absolutely differently sounding.

[quote user="Romy the Cat"] The S2 has own very idiosyncratic upper range with own helpful resonances injected into sound. I feel that that original metal suspension diaphragm does it bolder and more aggressively then the plastic suspension dia...

Well, I have to admit that I did not listen the whole sound of AC vs. DC filaments yet. I will bring home today my DC lab supply that I use for my electromagnet coil and will give the try. I still at this point am not concerned about the “whole ...

I have one of my newest Micro Seiki RX-5000 sitting in basement for years and doing nothing and I decided to let it go. I was keeping it for year as some kind of back up TT, in case my 8000 got broken or as TT that I would be able to use at...

[quote user="Amir"]these are my findings about computer audio after some trial error:1. computer audio is very very hardware/OS/software dependent. computer structure is multi task (time sharing) and using it as a real time single task processor is n...

[quote user="Paul S"]Frank himself will often cut in at this point to head off most of the speculative nonsense. Not to co- opt him here, but I find it interesting that most of the Schroder arms (sorry, no umlaut...) are particularly subject to ...

Hello Haralanov,It is hard to talk about sound, and define points: this is why the post is so long.Most systems I have lisitened to that measure a flat response have exagerated high frequencies and usually the midbass is a little shy, this might be ...

Here is an article by Leonard Norwitz that I think some of you might find motivating. I do not know Mr. Norwitz but it sounds like dinked too mach Qvortrup’s coca-cola. Anyhow, although I do not agree with some (sometimes many) of the Mr. Norwitz’s c...

I have not opened my bearing yet to change the oil, following the philosophy of “if it ain’t broke, don’t fix it”. It’s a different situation here than a car’s oil. The seals prevent the oil from being exposed to oxygen, moisture and other contam...

user="Wellington"]Perhaps the best test is to
play well-recorded piano which runs up and down the scales. Notes exciting
resonances may sound slightly louder, with more smearing and sustain. When
resonances are vanquished, the music flows ...

Sorry, but I have to tell you that you do have it backwards on the skating forces. Just Google for a force diagram. Another way to know is to look at how the anti-skating force is applied in arms using the weight, pulley and monofilament line approac...

[quote user="dkarmeli"]If the rest of the setup is up scratch then all you get is the recording and you'll forget about they system. Your body and mind will relax and allow you to have the same emotional connection with the music as you'd have in a l...

It looks like the Air Force prodigally follow the rule of
the game: to introduce some kind of flashy avantgarde model, make a lot of noise
over it and then while the noise up to introduce a less expensive model that
collects the publicity of the f...

It is entirely possible to buy a good flat CU-180. I have two from eBay there were correctly advertised as being flat. I have also seen them on eBay as being "slightly bent". Those you avoid.But I agree that a replica is a real possibility. I never s...

As I grow old and nurse a fragile back, I too have a fantasy of a good sounding, lightweight TT (and amp, speakers for the matter).Every lightweight TT on the market makes me interested for this reason

It's starting to look like an unspoken rule that a contemporary "TT manufacturer" is expected to offer a "package" that includes an arm, and many of these folks even offer "their own" cartridges, as well. It also looks like many of these "combin...

Stitch, I am not too familiar with the sound of contemporary TT and I am not necessary would discard them juts because they are contemporary. I still have that fantasy about some kind of flimsy, paper-made TT that for whatever reason do sound very go...
