| Is my amp "High Current"? One easy definition of a 'high-current' amp, as Monty mentioned, is one that has a continuous-power rating of double its output power as the load halves its impedance. This test is rather strenuous, and many amps just can't do it. The key word her... | |
| On-board subwoofer amps - limited shelf life ? Shadorne: "I don't think you can generalize, however, I have stopped buying Sony products."Me too after THREE 23" Sony monitors died within about 5 months. I replaced them with a quite-inexpensive Princeton 20" 1.6 monitor at Costco and am very ha... | |
| MultiChannel too complicated for most... "You suggest that 2-channel is like standing in an open doorway rather than in the theater. I find that much mc is like being in the center of the orchester and having a blanket over your head. You may know the music is all around you but it has n... | |
| I need help on directionality of speaker cables Oh my...the measurists are out in THIS thread. Do you guys ever LISTEN CAREFULLY to this stuff? And even if you do and hear no difference, do you believe that no difference exists...that is, that NO ONE can hear a difference? (That really is a que... | |
| MultiChannel too complicated for most... Those who write they don't like multichannel (NOT multi-channel) music don't indicate what kind of music they prefer. I absolutely LOVE the new MC recordings of Classical music. They really do enhance the (artificial, of course) feeling of being i... | |
| Tube lingo question To language policeman Herman--yes indeed it's highly sensitive speaker, but it's also high-sensitivity speaker. A noun can't be used to describe another noun? It certainly can in compound modifiers such as four-door sedan and high-gain amp, where ... | |
| Tube lingo question Herman--TY. :-)Gjames: "If you have a highly microphonic pre-amp (sic)...". Well, equipment very seldom is microfonic; TUBES are. So...if the tubes in a preamp* are highly microfonic, it probably is virtually unlistenable, with LOTS of ringing and... | |
| Dealing with HVAC vent air flow noise? I've been working on my 2-part AC system for years, succesfully. It takes time, money, and patience. My attic unit's 11-speed blower assembly (that uses 3 of those at any one time) has been running on the 3 lowest speeds for a couple years. I fina... | |
| Tube lingo question 'Tube rush' is a relatively continuous noise composed of random noise mostly in the middle and high frequencies. If the noise is predominantly high frequencies, we call it hiss.'Microphonics' is electromechanical noise that is created within the t... | |
| Open Baffle Terminology? 'Open baffle' means 'not closed'. The baffle may be a narrow plate (of MDF of other wood) just large enough to hold the drivers, or it may be somewhat elaborate, as my angled-back wings attached to 11"-wide frontplates are. But the defining princi... | |
| Preamp Caps?Auricap,Mundorf, Hovland, jensen,solen Sherod: "As I understand the formula for determining the preamp output cap value, the lower the cap value, the lower the bass -3db roll-off point..." No, Sherod, that's backwards. The formula for determining the -3dB ("filter") point of a hi-pass ... | |
| Is it double taxation? Avguygeorge is correct--the eBay seller is a dealer and must PAY salestax and is allowed to pass it to the buyer...at least that's the way it works in AZ.. | |
| Transverse-mounted ribbon tweeters? Greg, John--'narrowing' the vertical response? I think not. Mounted vertically, ribbon tweeters have very little vertical dispersion because they're relatively tall. Horizontal dispersion is wider. When one mounts it 90 degrees off vertical, or ho... | |
| Best sounding SACD regardles of music Try Telarc SACD-60433, Film Music of Jerry Goldsmith, wiht Goldsmith conducting the LSO. It has a huge bassdrum, great depth, dynamic range, and instrumental color. My only wish is that the strings didn't sound quite so thin.Great music too--from ... | |
| Tube issues Mumbo jumbo? Obviously I'm not seeing the BAT material, but BAT has to be addressing the OUTPUT tubes, not the frontend tubes. Various versions of the 6SN7 are rated for higher Voltages than others, but I've never seen an audio-equipment manufacturer write any... |
