| Current limit onset definition? Hi Ralph,Yes, but it is also true that 90 amps into 0 ohms is 0 watts (or, more precisely, some relatively small amount of power since no conductor can be exactly 0 ohms, assuming the temperature is not near absolute zero). Isn't it possible **in ... | |
| Help with cartridge output Sounds like the two channels may be wired out of phase relative to each other. Try reversing the connections to the cartridge for one channel (i.e., interchange EITHER blue and white OR green and red) and see what happens. Of course, have everythi... | |
| Help me improve Rega P2 Phasecorrect, the OP's present cartridge has a recommended load capacitance range of 150 to 400 pf. The 2M Blue that was suggested has a recommended load capacitance range of 150 to only 300 pf. My rough estimate of approximately how much load cap... | |
| Current limit onset definition? 01-07-15: PtssAck, confused, there are no newer DMA180's that I'm aware of. What do you mean?He means newer models having different model numbers (DMA-200S, DMA-260, DMA-300, DMA-400). Although as I indicated in my previous post the first three of... | |
| Help me improve Rega P2 Matt, Rega may be all about being simple to use. But the unusually high input capacitance of the OP's phono stage makes the use of that phono stage not so simple, if one places any faith in the load capacitance recommendations provided by the cart... | |
| Current limit onset definition? 01-05-15: AckThe "6" is indeed an "8" - 8A.... Newer amps have 5A fuses.Thanks for the info, Ack. It seems that the specs at the Spectral site for fuse ratings have not been done very carefully. In addition to the discrepancy regarding the DMA-180... | |
| What's the greatest bargain in SET these days? 01-06-15: Charles1dadI suppose it's possible to have good quality transformers that suffer unusually high output impedance.Agreed, Charles. My comment should not be taken as implying that the output transformers are not "good," or are not capable ... | |
| What's the greatest bargain in SET these days? 01-06-15: Charles1dadI wonder what accounts for such a high output impedance of the Dynamo. The Frankenstein has an output impedance of 1.8 ohms, quite a difference.Good question, Charles. I don't know the answer, of course, but if I were to hazar... | |
| What's the greatest bargain in SET these days? P.S: My post just above went up within a few seconds of the one just above it by Tubegroover, and was composed and submitted before seeing his. Great minds think alike!Best regards,-- Al | |
| What's the greatest bargain in SET these days? Rebbi, thanks for calling attention to the Dynamo review. I haven't received my copy of that issue yet, but I'm particularly struck by the mention of the amp's high output impedance. A 10.2 ohm output impedance/source impedance on the 8 ohm tap wi... | |
| Audio Research GS150 Musings Jasper, thanks for providing the link. Bruce, yes an electrostatic element can very reasonably be thought of as a giant capacitor, although the resulting impedance variation as a function of frequency will be modified by the step-up transformer th... | |
| Current limit onset definition? P.S. to my previous post: I found some rear panel photos of the DMA-180, which although difficult to read I believe indicate that the AC line fuses for 120 volt operation are 6 amp fuses, not 4 amp fuses as indicated at the Spectral website. That ... | |
| Current limit onset definition? The 683 watt spec (for a 2 ohm load), like most amplifier output power ratings, is a rating of how much power it can supply CONTINUOUSLY. Note in the specs for the DMA-180 that just above that number and the numbers for 4 ohm and 8 ohm loads, it s... | |
| Cables best suited to electrostatic speakers Hi Jim,The one thought I would offer is that the inductance of the particular speaker cable is likely to assume increased significance when used with an electrostatic speaker than when used with other kinds of speakers. The reason is that the impe... | |
| Audio Research GS150 Musings Hi Bruce & Jasper,I couldn't find an impedance curve for any of the versions of the CLX, but the Anniversary version is spec'd at 6 ohms nominal and 0.7 ohms at 20 kHz. As with most electrostatics, the impedance presumably descends more or les... |
