| Class "D" amp? I do not have a clue. Do you? Mapman - you're right about low input impedance. My Rowland has extra board (with THAT1200 intrumentation amp) to increase impedance to 40k. | |
| directional cables? Al - agreed. I objected only to term "Flow of electrons" since it has nothing to do with fast flow of charge. I stated also that with AC electrons are standing practically still - hardly a "flow of electrons". We can say that electricity (electron... | |
| directional cables? OK - water in garden hose it is. | |
| Class "D" amp? I do not have a clue. Do you? Then I suspect that you Icepower having huge damping factor at low frequencies (about 4000) overdamped your speakers making very lean bass? | |
| Can Frequency Sweeps Damage Speakers? Heyitsmedusty - There is a warning on Stereophile test CD that tracks with high frequencies played at normal level will take out tweeters. Bad part is that some of the frequencies that can do damage are outside of our hearing range. One could modi... | |
| Class "D" amp? I do not have a clue. Do you? Coxhaus - I'm surprised since I know audiogoner who drives with Icepower speakers with nominal impedance of 1 ohm.Isn't Spectron a class D amp as well? There is probably more to it than just impedance alone. | |
| directional cables? Herman - In addition people believe that since charge flows back and forth (AC) energy does the same and directionality of the cable doesn't exist. Energy flows one direction from source to destination. Some explanation here:http://amasci.com/misc... | |
| directional cables? Simply_q Once again - Electric current is a flow of charge ALONE. At 1kHz electrons are practically standing still (vibrating +/-0.0001mm) NEVER MOVING ALONG THE CABLE while charge is reaching destination with almost speed of light (0.6-0.7).Elect... | |
| Class "D" amp? I do not have a clue. Do you? Mike - Problem with switching power supplies is that most of them are designed to save money and space and not to improve performance. REF1000 for instance in improved version REF1000m has additional power supply with a lot of capacitors on separa... | |
| Which purchase tipped you into nirvana. Hyperion HPS-938 speakers. Open, vivid but natural and relaxed/musical sound (with class D amp) - just opposite to Hi-Fiish sounding speakers. Incredible midrange. Uses speakers without suspension (spiderweb). Midrange 6 1/2" is damped with ferrof... | |
| Is Acoustic Zen better than Harmonic Tech? "As AZ Absolute is all silver, does it not sound a bit lean in bass?" AZ Absolute IC is 1% copper while AZ Silver Reference IC is 3% copper. Bass with Absolute ICs is strong and well controlled/defined - at least with my gear. | |
| Class "D" amp? I do not have a clue. Do you? "With medium efficiency speakers the MEASURED peak voltage is above 100v." - I don't understand it. What speaker efficiency has to do with the voltage. Icepower 1000ASP voltage is regulated always 80V and since it is bidirectional it becomes +/-80... | |
| Class "D" amp? I do not have a clue. Do you? Pugstub - It might be related to fact that Icepower's full bridge places half of supply voltage (30-40V) on both speaker terminals. Non-powered speaker sees only voltage between terminals (difference) but ground referenced powered speaker might no... | |
| Class "D" amp? I do not have a clue. Do you? Afc - Ref1000 can drive 2ohm delivering 40A. Size of power supply has nothing to do with it since 2" toroidal transformer at 100kHz can pass as much power as 10" toroidal transformer at 60Hz. In addition voltage doesn't drop since it is line and l... | |
| Class "D" amp? I do not have a clue. Do you? Orpheus10 - I have Rowland Model 102 based on the same Icepower modules as mentioned Bel Canto S300 (and M300). It is very smooth and transparent (nice liquid midrange) but also very revealing. With new speakers (Hyperion HPS-938) I can finally he... |
