| Digital Source Comparison - An audible difference? In addition to sonic differences that may or may not result from differences in transport-generated jitter (depending on the amount of that jitter and on the jitter-rejection capability of the dac), if the connection between transport and dac is v... | |
| Are Disc Players Dead? Hi Mac,I wouldn't be so sure. On the NewEgg.com page for this Drobo model, click on the "Feedback" tab, which currently shows 114 user comments. Sort them by "lowest rated," and read the comments by the 20 people, out of those 114, who gave it the... | |
| Are Disc Players Dead? Hi Mac,Yes, a Drobo is definitely a neat approach. Keep in mind, though, that neither it nor anything else is 100% fail-safe, and so it doesn't eliminate the need for a separate second backup for really important stuff. For instance, if the power ... | |
| Are Disc Players Dead? 10-04-11: JeffreybehrDo remember that there are only 2 kinds of HDs--those that have failed and those that will. Very well put. My perception has been that hard drive longevity is pretty much unpredictable, and any correlation between the likeliho... | |
| RCA to XLR Adapter No, don't do that. There would be a gross impedance mismatch between the output impedance of the player and the impedance of the cable, resulting in waveform distortion. Also, you would be putting an unbalanced digital signal into a balanced input... | |
| CONUNDRUM FWIW, the Rothwell Attenuators, and I would imagine most other comparable devices, are configured in the same manner as what Jonathan has described, with a series resistor, and with a shunt resistor at their output. I have a pair of the Rothwell's... | |
| CONUNDRUM Hi Bruce,I wouldn't expect load capacitance to be relevant to issues at bass or subsonic frequencies.Yes, the Maestro isn't optimally loaded by the capacitance of the PH-7 + cabling, but I have no way of knowing how significant the resulting sonic... | |
| CONUNDRUM Bruce (Bifwynne), good points about load capacitance. I don't recall offhand the particular discussion you are referring to, but let me clarify a little further.For cartridges having high inductance, such as most MM's, the load capacitance seen by... | |
| Is 60dB gain enough for Kleos? Dave, those numbers all seem reasonable to me, and I don't see any issues with them.Gain, btw, is calculated as 20log(Vout/Vin). For the AV7005, that would be 21.6db for the balanced outputs, and 15.6db for the unbalanced outputs.Again, as I see i... | |
| Is 60dB gain enough for Kleos? I would be cautious extrapolating from experience with the Linto. In addition to the fact that it is solid state, as indicated in its manual it is a very unusual design in that it drives the input signals directly into the amplifying transistors, ... | |
| Is 60dB gain enough for Kleos? Some 60db phono stages will be fine, and others will not be.Assuming that your line stage preamp provides a reasonable amount of gain, say 10db or more, and that your power amp has a typical sensitivity number, say 1.5 volts or less (unbalanced), ... | |
| Lightspeed Attenuator - Best Preamp Ever? 09-28-11: Banquo363Am I right in believing that non-ideal impedance match between phono stage and LSA results in a attenuation of the high end? Perhaps it hasn't bothered me because of my old ears? Not necessarily. It depends on how the two impeda... | |
| Help system not working OK, good clarifications. Given that, I think putting a 10db attenuator at the inputs of the Calypso stands a good chance of resolving the distortion/overload problem, possibly with another pair of attenuators at the power amp inputs to allow you t... | |
| Help system not working One follow-up to my previous comment. Are you completely certain that you have set the jumpers in the IO for minimum gain (approximately 50db), as indicated on page 4 of the manual?If the specs on all of the components are accurate, according to m... | |
| Help system not working Another option is to insert an inexpensive passive attenuator between the phono stage and the preamp, such as the balanced version of the Rothwell 10db attenuators.I'd be very surprised if the input stage of any reasonably designed line-level prea... |
