[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...

[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...

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...

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...

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?

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...

I'm off to by-amp my computer speakers with dedicated monoblocks.
Seriously, it does not seem impossible that these things might do "well" within a limited range ; I mean, if they were not called upon to also produce sound outside that range.... i...

I was traveling yesterday and away from the computer until this evening. I'm glad to see my post as the source of controversy and even cause for a public flagellation from Romy. I don't know whether to laugh or to cry. Actually, I d...

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...

[quote user="manisandher"] Also, when I switch from AC to battery, the output voltage (as measured by a true RMS voltmeter) INCREASES by between 3-4V. Now, I am NOT suggesting that this increase in voltage is causing the difference in SQ. However...

[quote user="Lx_"] Well, this is consistent with the behavior I have. I can hear electrical devices behind the PP, especially those of the switching PS type: computer screen, laptop charger, DSL box, printer, SAT decoder... Good luck finding electron...

Forgive me for being so forward, but I have been holding it in for some time, and am right now, at this very moment, ripe for saying that I see this MiniMe thing as being analogous to an affair with a capricious little mistress bitch on the side. One...

From Larvy Site:Features like a USB input, programmable settings, infrared remote capability, and the proprietary >PiC< Playback Image Control™ make the DA11 more than just a great sounding DA converter. In keeping with the Lavry Engineering tr...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

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...

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'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...

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...
