Power from the company grid is usually pretty decent in most respects, or at least it used to be. In the last 25 years or so the average home has seen an increasing number of devices which have switching power supplies (computers, monitors, etc...

I am using the Celestion Axi-periodic compression driver in the KLIPSCH K402 horn which I have boosted considerably when I noticed that the top one and one-half octaves were barely working when playing music so I figured WHY NOT? and it works just f...

[quote user="Romy the Cat"]I would leave the bitching about the FM quality of today to other threads. In thins there I more interested about the today’s tuners. It might be said that no on need a good tuner if we listed the stations broadcasting MP3 ...

Hi Romy: I did not find any computer-based HD Radio receivers. The following link to HD Radio receiver Manufacturers does not seem to list any IT firms: http://www.ibiquity.com/manufacturers/receiver_manufacturers So, I spent some time researching H...

Romy, I have to admit that there are as many differences in film caps as there are in electrolytic caps. You can find varying opinions for and against both based on brand, type and usage. As noted, large value film caps get (physically) large so you...

I did not shoot for the Collectors' Holy Grail to start, but I looked for and bought a +/- "generic" version. The 3.5" I bought are unusual only with respect to their atypical (smaller than the usual 4") cone. They are 88.9 mm, as I recall. Otherwi...

Dima for instance (and he has quite high expertise in the subject) claims that there no true 24bit converters available anyhow. BTW, with all advances of HDCD, that I fully appreciate, it makes send only on 16 bit. At 20...

since I came to GSC, I became more and more careful (at least trying) in proper choosing words, due to the need of expressing myself in a language which isn't my own, some finesse and subtleties get lost, so further explanation or underl...

I have tried a lot of tape recorders and different tapes of different quality, thanks to a few close friends. There is the Tape Project tapes which quality is always very good, and although the selection of music is very good they have a limited cata...

Romy,I merely thought that you felt I was riding roughshod over your advice, when it was in fact a degree of naivety requiring extensive clarification that may have made it appear thus. Regardless of your indifference to praise and/or criticism, I'd ...

From a technological perspective, these look very interesting. Unfortunately the nearest place i could audition these is Montreal, but it looks to be worth it. Have you heard these, Romy, or are you also impressed with the price/technology ratio?

[quote user="rowuk"]Amir,you have now posted twice that "proper" USB is better than SPDIF. The problem is that it isn't, unless someone makes up rules to define their own sense of better. The problem here is that they have not defined anything that i...

I've used both tube and solid-state rectification over the years and much is well documented for power supplies, i.e., old ARRL manuals, Tube manuals, etc.. In most cases small value filter caps were shown, as you really couldn't get much in la...

It looks like my computer playback box is kind of dying, not to mention that it is hugely outdated now. It is 10 year old box that still run on Win XP pro and 4G memory. It begins to throw fists here and there; it is time to replace it, I think that...

I think I get your message Romy, but offer an alternative perspective to DIY.The results depend on the motivation and expectations of the DIYer. For example, saving $$$ is one reason to start learning to solder and build simple circuits. ...

So, my point is that I do not care if one or other company trade their regenerators and that I might get the same or near the same cheaper somewhere else. There is many Class AB power regenerators that are being use in...

OK, the next step is kind of done. All transformers and chokes are done form “outside” of the amp (under the bulge). I have attached the capacitors and the output transformer to the “inside”. This silicone attachment that for the computer grade...

I think that picking a DAC is like picking speakers - regardless of the price, we don't know what we have until we get there. I do not think that it is possible to compare digital and analog playback forms. With a turntable we have as many choices (g...
