| Is DEQX a game changer? Hi Bruce,The Quatro CT does seem intriguing to me, with respect to your circumstances. Presumably there would be no need with it to go to the trouble of doing speaker calibrations with the DEQX, and of course doing room corrections is a much simpl... | |
| Absolute top tier DAC for standard res Redbook CD From a technical standpoint, the paragraphs George quoted from the MSB literature all make sense to me, as opposed to being the kind of marketing techno-babble that seems all too common in audio-related white papers and other literature. An additi... | |
| Is DEQX a game changer? Bruce, no, as it turned out I didn't get a chance to re-do the speaker measurements this week. And I've got a number of other things scheduled for the next several days. So it might be another week or so before I'm able to do the measurements.Mean... | |
| Looking for really fine cables at really low price 07-09-15: MetmanI have a straight run from speakers to amp - no braiding or twisting and it sounds pretty damn good. Will I realize an additional benefit twisting the + and - around each other from speaker to amp?The main effect of twisting + and ... | |
| Why Listen To FM Radio For Music Anymore At Home? I would add to what has been said in support of FM that there are reasons classic vintage tube tuners such as the Marantz 10B, the REL Precedent, certain models from H.H. Scott, Fisher, McIntosh, etc., often sell for thousands of dollars. And it i... | |
| Matching the sensitivity of two amps for bi-amping Hello Nik,First, to be sure it's clear, "higher sensitivity" = a lower sensitivity number, assuming that sensitivity in each case is defined as the input voltage required to drive the amp to its maximum rated power.Second, per my earlier comments ... | |
| Elrog 300B vs Takatsuki 300B tubes Slight correction to my slight correction :-)When I said in the long post prior to the correction:So the actual voltage when you measured 123.1 could have been anywhere from 120.6 to 125.6 volts.I should have said:So the actual voltage when you me... | |
| Elrog 300B vs Takatsuki 300B tubes Slight correction to my previous post. When I said...For your worst case reading of 123.1 the accuracy would be +/- 2.48 volts... I should have said:For your worst case reading of 123.3 the accuracy would be +/- 2.48 voltsThe rest of the calculati... | |
| Elrog 300B vs Takatsuki 300B tubes 07-08-15: TmmvinylI know very little about multimeters; mine is the Commercial Electric, Digital Multimeter, Model # MAS830B purchased at Home Depot.Using the 200V measuring range, accuracy is listed as +/- 1.2% rdg +/- 10dgt. Given that the meter... | |
| Elrog 300B vs Takatsuki 300B tubes A point to keep in mind regarding the AC voltage measurements some of you have been making: Although a digital multimeter may provide 4 digits or more of resolution (i.e., to tenths of a volt when reading voltages in the vicinity of 120), its read... | |
| Elrog 300B vs Takatsuki 300B tubes 07-07-15: TmmvinylAm I correct that I should not be using my Takatsuki tubes in the Frankensteins given my high voltage readings?I haven't been able to find a datasheet or detailed specs on the Takatsuki tube. Can anyone provide a link to that inf... | |
| Matching the sensitivity of two amps for bi-amping I too agree with ZD. I would add, with respect to the passive biamp configuration you are proposing, that in most cases it would not be correct to match the sensitivities of the two amps. What should be matched is their gain, the relation between ... | |
| Passive attenuator impedance question Gmudunuri, I suspect that either of those approaches would work well, but I'd suggest going with the three resistor approach. Not only because it would use one fewer resistor per channel, but because of some probably very minor but perhaps signifi... | |
| Elrog 300B vs Takatsuki 300B tubes Bill (Brownsfan), thanks very much for the nice words.Charles, I suppose it would be reasonable to try that experimentally with an inexpensive variac, perhaps purchased used at eBay, but it wouldn't surprise me if the result was degraded sound qua... | |
| Elrog 300B vs Takatsuki 300B tubes 07-07-15: BrownsfanMy power company will not address the issue unless the voltage is outside of 120 V plus or minus 5%. That is the standard in the USA for household AC, as measured at the service entrance. The upper limit of that range correspond... |
