| 10 db or 20 db attenuator? Thanks, Bob. But of course some problems are more easily solved than others :-)Best regards,-- Al | |
| 10 db or 20 db attenuator? If the volume control is a rotary type (as opposed to one having "up" and "down" buttons) the following photo will probably enable you to determine a reasonable approximation of the difference in volume control settings that would result between t... | |
| DO CABLES REALLY MATTER? Corrected second link:https://positive-feedback.com/audio-discourse/rcl-part-2-roger-skoff-cables/(The "http://" should not have been there, and the "https" should have had a colon after it).Regards,-- Al | |
| Threat of fire from audio equipment Thanks for calling the article to our attention, Howard. Regarding your questions, IMO all that can be said is the not particularly helpful common sense notion that in general the risk is very small (perhaps less than the risk of driving a car), b... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Regarding differences in cable propagation velocity as a function of frequency, the following paper (which I and another member had referenced in posts here a few years ago) appears to me to be credible as well as informative:http://www.audiosyste... | |
| Pass labs xa25 amp and BW 804 d3? A minor point but one that should probably be mentioned is that the Vandersteen 5 has a built-in amplifier handling the deep bass. And it is designed to be used with a passive high pass filter inserted between the preamp and the power amp, which r... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @flashbazbo, the caveats that occur to me regarding adding a BNC output to your player are:1) Be sure to select a 75 ohm BNC connector, rather than a 50 ohm BNC connector.2) Looking at rear panel photos of the player, as might be expected it appea... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ffzz, you’re welcome!My former VAC Renaissance 70/70 MkIII amp is a class A amp employing four 300B power tubes per channel, in a push-pull parallel configuration, and is rated at 70 watts per channel. It is a 100+ pound beast, which I believe co... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ffzz,Yes it is. See two of my posts ealier in this thread, dated 11-26-2018 and 11-27-2018, which appear on pages 5 and 6 of the thread if you have it sorted with the oldest posts first.Regards,-- Al | |
| Relative component value to overall SQ. @N80, I believe that the helpfulness of the responses you receive may benefit from some clarification of the question.I and I believe some of the others who responded earlier in the thread interpreted your asking about "relative component value t... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @Jafox, to add to the responses Roger and Ralph have provided to your question, fyi I believe that as a special order item Cardas can supply XLR-female to RCA-male adapters that leave pin 3 unconnected, rather than shorting it to ground (pin 1) as... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Ramtubes 12-26-2018 daveyf:first the swapped polarity from amp to speaker does no harm and most will not hear any difference as long as the swap is the same on both sides. All you have done is invert absolute phase which has been a point of conten... | |
| Pass labs xa25 amp and BW 804 d3? @Cal3713, I’ve sold the VAC Renaissance 70/70 MkIII amplifier and I’m using the XA25 exclusively. I decided to purchase the XA25 a few months ago while the VAC was back at the factory for a minor repair, motivated mainly by all of the glowing revi... | |
| Monostrapped Atma-sphere M-60 In addition to more power, a potential advantage of monostrapping (i.e., paralleling) Ralph's amps is that the resulting output impedance would be cut in half. In the case of the M-60 Mk 3.3 for example, the output impedance of a monostrapped pai... | |
| Relative component value to overall SQ. As you no doubt realize opinions on this question will vary widely, in part because systems, components, rooms, listeners, preferred listening volumes, and listener preferences among different types of recordings (including the dynamic ranges of t... |
