| Speaker Cable Malarkey (“Ghost” Cables) Plot twist: Does this 20 gauge wire that is only connected at the amp need a break-in period? Since that wire would be conducting no current, aside from the infinitesimal amount that might result from antenna effects, it's hard to imagine how any... | |
| Recommendations on stuff to look at for upgrading a 300B SET amp As a point of information, while I’m not totally certain I believe the LM-805ia is the same amp as the LM-508ia that Shkong78 suggested earlier, and that is owned by at least one other highly respected member here, namely Waltersalas. Perhaps the ... | |
| Speaker Cable Malarkey (“Ghost” Cables) In addition to the possibilities Teo mentioned, the cable that is disconnected at the speaker end may be acting as an antenna, picking up RF (radio frequency) noise, and injecting it into the feedback loop of the amp, assuming the amp has a feedba... | |
| Cat 5, 5a, 6, 6a, etc :-)When I saw your previous post I was about to respond that pretty much all you were likely to find on the subsequent pages was a lot of controversy.In any event, IMO whatever differences may result, if any, figure to be highly dependent on the s... | |
| Cat 5, 5a, 6, 6a, etc Hi Bob,See my three posts on the first page of the following thread (assuming you have posts sorted oldest first):https://forum.audiogon.com/discussions/most-important-unloved-cableI would not assume that a cable having a higher Cat number would n... | |
| GO PATS! Contrary to what some are saying here and many are saying elsewhere, I found it to be a very exciting game. Close, tension-filled, and well played on both sides. (One indication of that being that each team had only one turnover). As others have ... | |
| Pass labs xa25 amp and BW 804 d3? @jetter, like many of us I wouldn’t consider my range of experiences to be extensive enough to put it quite as broadly as you did in your question. But I would certainly consider the XA25 to be a very strong candidate that should be considered by ... | |
| Voltage delta between speakers The inter-channel differences correspond to about 0.27 db for the Cary and 0.36 db for the Classe, which seem to me to be small enough to not be a concern.The 10% difference you mentioned corresponds to between 0.83 db and 0.92 db, depending on th... | |
| Too good to be true? @Jetter, Figure 1 of Stereophile's measurements of the Martin Logan 15A, which appears to be a fairly similar big brother of the OP's 11A, shows that even though the crossover point between the powered woofer section and the electrostatic panel is... | |
| Inverted Phase Preamplifiers with REL Subwoofers Whatever you do, don't reverse the sub connections such that the black (ground) wire from the sub is connected to a + output of the amp. That can cause problems ranging from hum to damage, depending on the internal grounding configurations of the... | |
| Too good to be true? Kosst, thanks for the good info! I'll check out the Burning Amp lecture.And +1 re Tomic's suggestion of contacting Mark at Reno HiFi. That is the dealership I purchased my XA25 from. In addition to providing generous trial/return privileges, he... | |
| Impedance match Thanks for the excellent input, George.An additional point everyone should be aware of is that how objectionable a given low ratio is likely to be depends not only on the ratio itself but also on how much variation that ratio has over the frequenc... | |
| Too good to be true? My **guess** is that you’ll be ok pairing the XA25 with the ML 11A if your room is of average size or less, and if (as appears to be the case) your listening does not include recordings having extremely wide dynamic range (such as some classical s... | |
| DC Offset Blocker/Killer - where to buy in the USA FWIW, my reading of the thread leaves me with essentially zero doubt that the OP is being entirely truthful. And I agree with him that it is very likely that investing the time, physical effort, and money that would be involved in sending the amp... | |
| Upgrade from Pass Labs XA30.8 to X250.8. Worth it? Your calculation of the 18K is correct, and I feel pretty certain that your diagnosis of the bass issue is correct. The 18K load impedance divided by the 4.7K output impedance at 20 Hz is a ratio of 3.8, well under the rule of thumb guideline of a... |
