| Which high power SET Ait, congratulations on what is certainly one of the most spectacular DIY amplifiers ever!As a point of information that may be relevant to the thread, do you know what its output impedance is, or alternatively, its damping factor?Also, what load ... | |
| Phono rig capacitance First, kudos on your interest in applying engineering principles to audio, and thereby trying to reduce the randomness that often seems to be inherent in optimizing a system. And in that regard I recall your earlier thread on “moving coil stepup m... | |
| Analyzing the power from the outlet The previous discussion to which Lak refers, of essentially the same question, was in this thread, beginning with the post the link opens at.As you'll see, IMO measurements of AC noise, even with sophisticated instrumentation, are unlikely to be h... | |
| Which high power SET Edoit, I second all of Larry's comments, including his emphasis on the word "may," except that I would add "widely varying speaker impedance" to his mention of low speaker impedance.The fact that the speaker's impedance varies widely, from about 6... | |
| Which high power SET 06-24-14: EdoitTo rephrase my question, which of the 3 on the list would be the best match for shindo masseto pre amp?My suggestion is that a more important consideration is which of the three amps is the best match for the speakers. As you can se... | |
| Sloped baffle 06-24-14: BifwynneI'm hoping Al and Ralph weigh in here to help us better understand the relative significance of phase coherence as compared to other factors. Hi Bruce,As I indicated earlier, speaker technology is not one of my areas of expertise... | |
| What Exactly Does "Burn In" do for Electronics? 06-23-14: GeorgelofiSo it seems like we are in agreement, that to us "break in" for better or worse can occur with the mechanical devices such as speakers drivers, cartridges, and tubes, as you also said.And you and I will not commit without skirt... | |
| What Exactly Does "Burn In" do for Electronics? George, what I was disagreeing with were the three assumptions I listed that your disagreement with ZD appeared to be based on. As far as my own beliefs are concerned, I think we are all agreed that speakers, cartridges, and tubes will change thei... | |
| What Exactly Does "Burn In" do for Electronics? George & Peter (Csontos), I would respectfully disagree with what appears to be the logic behind your recent posts, at least with respect to electronic components (amps, preamps, digital sources, etc). It seems to me that implicit in your logi... | |
| What Exactly Does "Burn In" do for Electronics? As I see it, it can be expected that by the time developmental testing is completed on the prototype of a new design, including final tweaking/voicing of the design, the prototype is likely to have accumulated a MUCH greater number of hours of ope... | |
| Sloped baffle 06-22-14: BombaywallaWhy the differences? Because the Vandy 7 is time-coherent & the Revel2 is not!Bifwynne, if you click on the link provided by Tls49, you will see exactly why as you read the text there. Scroll down where Roy J talks about t... | |
| Wall Outlet Oyaide, Furutek, Wattgate, and others 06-21-14: JazzonthehudsonTo Almarg: as for reducing the resistance, should one consider soldering the joints additionally? My guess is that use of a good contact cleaner would provide the same benefits (if any) that soldering would. As I indicated... | |
| Sloped baffle Bruce (Bifwynne), thanks for the summons. I haven't yet taken the time to read the links Bombaywalla was good enough to provide, but I am pretty much in agreement with all that has been said by the various posters above. Including the comment by K... | |
| Cars. What does the typical audiophile drive? 1999 Honda Prelude -- still in great shape!2001 Honda CRV -- likewise2014 Porsche Cayman S -- awesome!Regards,-- Al | |
| Interconnects & Speaker cables 75 feet! And with speakers whose impedance, as shown here, is less than 4 ohms in parts of the mid-bass which typically require lots of energy. Ouch!You need heavy gauge/low resistance, and fairly low inductance per unit length. You also presumabl... |
