| Is DEQX a game changer? Thanks very much, Pete, for the nice words and the interesting comments.An update: I've created and assessed three more speaker calibration profiles, this time based on the measurements I took with no acoustic panels in place. (As I had previously... | |
| Ayre or CJ With Vienna Acoustics Kiss I would add to ZD's good comments, and to your concern (which I share) about the adequacy for your speakers of the 125W into 4 ohm power capability of the CJ amp, that I suspect the impedance characteristics of your speakers (shown in Figure 1 her... | |
| Adding a resistor in a parallel wiring system Clever thoughts, Jim (Jea48). However, as you'll realize placing drivers or speakers in series will not produce good results unless the impedances of the drivers or speakers vary as a function of frequency in a similar manner. Which ideally means ... | |
| Jeff Rowland +1 Bombaywalla (with a slight qualification as described below).Richard, I see that you are using some rather expensive interconnects and speaker cables. In part for that reason I would reiterate my earlier comment to the effect that you wouldn't ... | |
| Zero autoformers -- how to measure impedance? Bombaywalla, based on info the OP has provided in another recent thread he is driving a combination of four drivers in parallel. Three of them are 8 ohms, and the other is 4 ohms placed in series with a 1.5 ohm resistor. The purpose of the resisto... | |
| Zero autoformers -- how to measure impedance? Ryan, yes, most multimeters can only measure impedance at a frequency of 0 Hz, or in other words, DC resistance. And given that, the numbers you cited seem reasonable, regardless of whether or not a speaker is connected (although the DC resistance... | |
| Jeff Rowland Now if I can't use bridged 525s or can't find a used 625 that has the most recent updates, I may need to look at other options.Richard, to be sure it's clear, using two 525's in a vertical biamp configuration completely avoids the potential issue ... | |
| Absolute top tier DAC for standard res Redbook CD Matt, for a checklist of manufacturers of time coherent speakers (which also implies phase coherence) see this post, and the response in the second post following it. Many of those mentioned will not meet your other criteria, however.Note: "GMA" =... | |
| Jeff Rowland P.S: Here are some XLR y-adapters.Regards,-- Al | |
| Jeff Rowland Richard, I have no experience whatsoever with Rowland equipment, but I do have a suggestion I think may be worthwhile. When you get the new amp, in addition to trying the two 525's in bridged mode, try them in a vertical biamp configuration (which... | |
| Need a power cord for Garrard 301. Good question, Lew. One conceivable explanation might be that the triple shielding provided in the Pangea AC-14 series cords which I suspect Darkstar1 is referring to could reduce RFI pickup from nearby components, cables, or power cords. RFI that... | |
| Adding a resistor in a parallel wiring system Hi Ryan,Glad the Zeros are working out well. I did some calculations and I agree with most of your analysis about the 1.5 ohm resistor. I calculate that if 25 watts is going into each of the 8 ohm drivers, 26.45 watts will go into the 4 ohm driver... | |
| Is DEQX a game changer? Ptss, no, my background is in EE, although way back when I certainly had my share of math courses, and a few that touched on philosophy. I also have a law degree, although I haven't practiced as such.Best regards,-- Al | |
| Which computer for digitizing and streaming? I suspect that the most significant factor affecting the sonic quality you will end up obtaining is the quality of the A/D (analog-to-digital) converter that is used. And although I have no directly relevant experience, I would be skeptical of the... | |
| Is digital contamination that big of a deal? 06-11-15: ChazroHarry Pearson recommended turning off your CD player while playing vinyl 25-30 yrs ago! But I never heard a difference. Either my system or my ears aren't resolving enough I guess.Not necessarily, by any means. From a technical sta... |
