| High Current SS amps with input impedance = 200K Guido -- While I certainly don't question your subjective comments, I don't think that the statement that 45 amps from a balanced amp output is roughly equivalent to 90 amps from unbalanced amp outputs is correct. If the spec is 45 amps (and btw I... | |
| Torn between two amps Neither amp should be energized if no direct connectivity is made to an existing speaker load.Excellent point, Jim. A tube amp, or at least a tube amp that has an output transformer, should never be operated without a speaker load.I believe, thoug... | |
| Torn between two amps I agree with Stan. I'll add that the effects of a y-connector arrangement will be highly dependent on the output impedance of the preamp. The lower it is the better. The preamp will see a load impedance that is equal to the product (multiplication... | |
| Can you help me identify this power cable? Also, at the same link, select "plug to wire leads" in the style column, and you'll get a much larger selection. If one of those has the correct plug size, you could purchase two of them and solder them back-to-back (i.e., connecting the bare wire... | |
| Can you help me identify this power cable? One of the cables listed here may be suitable:http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=1573698Highlight "plug to plug" in the "Style" column, then click "apply filters" at the lower left. You will get four results. If the plug size... | |
| Dynamic Headroom Magfan -- No correction needed. You don't need any dynamic headroom provided that brief musical peaks do not approach the 500 watts. Keep in mind, though, that 500 watts is only about 12db louder than 30 watts.Best regards,-- Al | |
| Dynamic Headroom Take a 100wpc amplifier that doubles all the way to .5ohms; That is Dynamic Headroom, at its very Best.Or another 100wpc amplifier, that produces 140wpc.@4ohms, and maybe 150wpc. @2ohms very briefly. The second amp. does NOT have ANY Dynamic Headr... | |
| Why did I get married? I agree with Tvad, Glory, and 280. Also with the suggestions of headphones. I usually listen with speakers either with my wife or when she is not at home. If my listening would interfere with something else she is doing, I use headphones (Stax ele... | |
| Your ONE all time favorite love song? C'mon...Somebody must have a favorite song by Schubert or PurcellI've already voted in this thread, nominating a song from a Broadway show, but based on a liberal interpretation of the phrase "love song" I'll give an honorable mention to Brahm's "... | |
| Dynamic Headroom Note that I said that "high dynamic headroom CAN also be an indication that the amplifier's power supply and/or its thermal design are 'weak.'" I did NOT mean to imply that a high dynamic headroom figure NECESSARILY means that the amplifier is def... | |
| Dynamic Headroom It refers to the ability of an amplifier to deliver a greater amount of power on brief musical peaks than the amount of power it is rated to deliver continuously.That can be good in the sense that the peak power levels required by a lot of music c... | |
| What are your fav “Off Hollywood” films If you can think of those ‘non main stream’ efforts, or those films which either didn’t get their due, or only a few likely know about, but are indeed, very good to great film experiences, please share your thoughts here."The Umbrellas of Cherbour... | |
| Running 4 speakers from a 2-channel amp Hmm, actually HifiTime's statement about highs passing through the woofer crossover is more correct than I initially thought. If speaker A is series connected to speaker B, the high frequency energy that manages to get through the inductor that is... | |
| Running 4 speakers from a 2-channel amp The highs and mids will all be traveling through the other speakers low frequency choke.With much respect, HifiTime, I don't think that is true. I believe that at any given frequency the signal will follow the same path or paths through each speak... | |
| Running 4 speakers from a 2-channel amp Re connecting speakers in series:1)To the extent that the speakers which are connected in series do not have identical impedance vs. frequency characteristics, frequency response irregularities will be introduced into each speaker. That is because... |
