| XLR, RCA or BNC? Of course only the XLR can be used for balanced lines, and balanced XLR should not be compared with unbalanced RCA. By the way, there is no reason why XLR could not be used single ended. There are also "phone plugs" of various sizes that can be ei... | |
| Amp/xover for Hartley 24 subwoofer The Audio Control "Richter scale" is what you want. 24 dB slope for both the subwoofer and Maggies will keep them inphase with each other at X/O. Also, the steeper slope will do a better job of keeping the Maggie diaphrams from flopping around try... | |
| ultra low capacitance cables Brainwater...Enough already! We all try to help in our own ways. My specialty, in case you haven't noticed, is to jump in when scientific principles are inappropriately cited to support some audiophile myth, that would be better justified as an ar... | |
| ultra low capacitance cables Suggestions:1. DIY as Sean suggests (unless you just want to get rid of some money). You can buy wire and connectors just as good as what the high priced labels use.2. Keep them short (again as Sean suggests).With your tube gear I do think that th... | |
| ultra low capacitance cables Brainwater...'less than 850 ohms' is quite high even for a tube preamp, although I have seen 2000 ohms quoted. High output impedance makes you sensitive to cable capacitance (HF roll off) and noise pickup. When I was into tubes, 600 ohms was the c... | |
| Hearing affecting soundstage Although my HF sensitivity is degraded (flying airplanes was my downfall) I don't have any problem with soundstage. Maybe that's because my old ears are equally bad. | |
| Speaker repair-need help Sean...Although I am a long time admirer of the FR Walsh driver I am not familiar with details of how it is assembled. However, as an engineer, I offer the following suggestions.1. Big picture...The existing design appears to be difficult to build... | |
| Do subwoofer magnets interfere with amplifiers? In general a dc magnetic field won't affect electronics, a TV CRT being the exception. The CRT involves a beam of electrons that are intended to be easily deflected so as to scan the screen. An AC field can cause Hum, but the power transformer of ... | |
| XLR, RCA or BNC? From the electric point of view there should be no difference, assuming all have clean contacts. BNC and XLR lock in place, so they won't get pulled out by mistake if you move stuff around. XLR are big and clunky, which makes them easy to handle. | |
| Speaker repair-need help Sean...Why the tease? You have told us that the Walsh driver has all these faults, and you have ways to fix them, but we have not the slightest idea what you are talking about. Quite frustrating to your readers. | |
| Universal Players that do not convert DSD to PCM? Why do you care? High Res PCM is as good (some say better) than DSD. Also most mixing consoles are PCM, and Sony's design for DSD recognizes this fact of life and makes conversion easy. Listen to the equipment, not to Sony's hype. | |
| Mono vs Stereo LP's 4yanx..."No record cleaner will remove that, it is part of the recording".Have you heard the "record cleaning" that can be done by digitizing the signal and processing it with a computer? Absolutely amazing. I am talking about recordings made almo... | |
| Subwoofer X/O frequency experiments Gregm...What you say suggests that the subwoofer should really be two-way, 20 to 50 and 50 to whatever, and I agree with this. Each of my three subwoofers consists of two drivers, 15" and 12" driven by separate power amps, and I have actually trie... | |
| Mono vs Stereo LP's Lots of old recordings had hiss (from tube electronics and pre Dolby/DBX tape recorders). To overcome this most preamps had noise filters, to roll off response as low as 6000 Hz. The best noise filters were "dynamic" (they cut in and out according... | |
| Speaker repair-need help Sorry about your loss.I really doubt that you can get anything out of the power company. It is a fact of life that power goes off and back on from time to time, and electronic equipment that can't withstand this is arguably faulty. When you tell t... |
