| What do I look for in used records? Wdi...You can tell if a record is stereo or mono by the appearance of the grooves. Grab two records that you know are stereo and mono, and see what I mean. | |
| What do I look for in used records? Pmotz...I believe that the first release of a stereo record was a Dukes of Dixieland LP from Audio Fidelity. I don't have that very first issue, but I do have several other Dukes records that they issued in the months following. The audio quality ... | |
| Wait a Minute Do those Cardas Caps Work Are we talking about shorting plugs, or just plain dust caps. Shorting plugs are a good idea, not so much when the input is unused as when you sequence through that input with your selector switch, and may hear bad noises from the open circuit. | |
| Minor phase plate incident with midrange of Hales If you think it might make a difference, and you need to punish yourself for being so clumsy, it will for ever affect your enjoyment of the speaker. I hope the phase plates didn't cost much. | |
| SACD 2 channel vs Redbook 2 Channel The SACD data format is completely different from the PCM redbook format, so that theoretical comparisons are not easy. There is an argument, posted elsewhere, that SACD resolution for signals above 8000 Hz is actually inferior.To my ears, and dep... | |
| Carver Pro ZR1600 lkosova@yahoo.com...Trust the lawyers to screw things up!sean...The circuit, which includes the OP Amp is linear, even if the open loop performance of the device is "junky". An analogy might be the output transformer of a tube amp, where, when tes... | |
| Subwoofer Amp Recommendations Ritteri...I guess I must be lucky to have no noise problems or QC defects. (Many, many excellent products are no longer made. There is another thread about this).I don't think that you can explain the need for high slew rate when processing a sign... | |
| Carver Pro ZR1600 sean...Yes, noise is a significant characteristic of an Op amp. However, the OP Amp circuit topography is such that an IC which is "junky" in other ways, like distortion (thermal or otherewise) gain tolerance, slew rate tolerance (as long as it is... | |
| Carver Pro ZR1600 Dmason...I hear the term "junk OP Amp" used a lot lately. What does this mean?With the exception of noise, the open loop electrical characteristics of an OP Amp have almost no effect on how it performs in a circuit, especially for a unity gain buf... | |
| Subwoofer Amp Recommendations Elgordo..."One man right (or even two men) is a majority of one". In their day the LO7M were considered the best. By now they are all well burned in...and still working!I have the service manual if anyone is interested. They are flat from DC to 50... | |
| Subwoofer Amp Recommendations Ritteri...My point about slew rate is that a subwoofer signal does not involve any "sudden changes", so the ability of an amp to track such changes is immaterial. The Kenwood LO7M is a true DC amp, with not a single capacitor in the signal path. I... | |
| Carver Pro ZR1600 Regarding mods...After studying the schematics, and reading about Mod activity, I "popped the cover" (a simple matter of sixteen screws) and looked inside. From what I saw I don't think much is practical with a few exceptions. The fan replacement ... | |
| Subwoofer Amp Recommendations Ritteri...Why is slew rate meaningful for a SW amp? Is "flat to 5 Hz" really significant? If so, I suggest a Kenwood LO7M, or other DC coupled amp, which is flat to DC. | |
| Subwoofer Amp Recommendations I don't understand why a Carver amp would be a problem with connections. Pls explain details. | |
| SACD VS DVD-AUDIO Leasingguy...You don't need video to play a DVD-A. Perhaps you should research worldwide sales figures. Several European audiophile labels are turning out superb DVD-A discs. I look for these first, and buy SACD as a fallback. |
