| Cause of different sound between dacs For a brief illustration of some of the complexities that are involved in optimizing just a couple of the many factors that have been cited by the others above, take a look at this paper (although it focuses on A/D rather than D/A conversion). Ent... | |
| Legendary used amp, or economical new one? Based on a quick search, it sounds like you are referring to a PMF-1150B :-)I have no particular knowledge of how those things tend to hold up after nearly 30 years, but considering the relatively low prices they seem to go for, and the generally ... | |
| Would a source selector switch degrade sound? Great minds think alike :-)Best,-- Al | |
| Would a source selector switch degrade sound? Why not just plug the AVR's left and right channel line level outputs into an unused pair of line level (non-phono) inputs on the RA-1062? Then determine a setting of the RA-1062's volume control that allows you to use the AVR's volume control at ... | |
| Well, worst of is really what this is about It's early in the morning here, but I doubt that I'll see a better post than Elizabeth's any time today. Thanks!Best,-- Al | |
| When did you start to love music and why? My love of music was triggered when, while listening to the radio in 1956, I heard Gogi Grant's recording of "The Wayward Wind."Regards,-- Al | |
| Speaker Impedance: Resistance and Phase Question Bruce, I'm not totally certain, but I believe the answer to your question is that at the crossover frequency the phase angle of the speaker's impedance will be zero degrees, i.e., it will appear to the amplifier to be resistive. Per your well stat... | |
| High Current vs high power Thanks, Bruce. Yes, looking at JA's measurements of the Revel Ultima Studio 2 and your Ref150, it strikes me as a reasonable possibility that they would be a suitable pairing, using the 4 ohm tap.George, I see your point. But I doubt that there ar... | |
| High Current vs high power George, I would respectfully, but very strongly, disagree with the notion that specs, and a good understanding of them, are useless.Yes, specs will generally provide little if any insight into how a component will sound. And I certainly agree that... | |
| Possible Desktop Speakers? 08-27-13: Jkmanal- yeah I'm a goober and just thought separate amp and pre would be better performance wise. I also thought the arc 150 was the max wattage which I believe was the max on the speakers. I guess you don't match speakers and amps that... | |
| Speaker Impedance: Resistance and Phase Question Thanks for the nice words, Mesch. Yes, JA's measurements, and the interpretations he provides in the associated text, certainly represent major contributions to the hobby. I couldn't begin to count the number of times I and many others have referr... | |
| Possible Desktop Speakers? I know Al may give me noogies for asking (given the price difference).Yup :-)The only way it would make any sense to spend $26K for pre + power amplification to drive $2K/pair speakers would be if you envision ultimately upgrading the speakers to ... | |
| Speaker Impedance: Resistance and Phase Question Thanks, Mesch. Regards to you as well :-)I second Larry's comments, except that his last sentence might be taken to mean that speakers ALWAYS "present an inductive load," which of course is not the case. Speaker impedance will usually be inductive... | |
| Preamp Noise with High-Efficiency Speakers ... when he OMITS the active pre (and he has tried 4 different ones solid state and tube) he is reducing his overhaul system gain by maybe 40db or more...George, note that he is talking about a line level signal from a DAC, not a phono level signa... | |
| Com'on...confess.......... I have about eight or so classical LP's from the late 1970's and early 1980's on the French label Astrée. Most of them are treasures musically, and simply incredible sonically. I mentioned one of them in the OP's recent "Favorite LP Of All Time" t... |
