| Shout out for Neil Young's Sugar Mountain Live LP I believe several weeks ago there was a news release that the Young archive release has been delayed yet again. Hopefully he's revisiting his decision to limit the release to BluRay. I bet you could could on one hand the audiophiles on this forum ... | |
| Rain-X as CD Enhancement Treatment Far from an imaginative leap into brilliant pebbles & the like, the theory with the colored edge treatment is that it filters out refracted light that may otherwise be reintroduced into the optics. It's also conceivable that a shiny smooth sur... | |
| Rain-X as CD Enhancement Treatment Douglas, while I think it's prudent to keep a balance between theoretical and empirical discussion, IMO the matter of jitter is a case in point that argues for an empirical approach involving an open mind and careful listening tests. As discussed ... | |
| Rain-X as CD Enhancement Treatment Shadorne,Webster's definition of scientific method: "principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formu... | |
| SP10 Mk II vs Mk III I think one of the advantages of carbon graphite would be constrained layer damping effects achieved by varying material thickness and directionality of carbon fibers. This is how it's done in bicycle frames to obtain strength where necessary as w... | |
| Atma-Sphere MP-1 Mk II vs. MIII With a MkII, a .3mv cartridge will be noisy without an SUT or a hybrid SS conversion as per my MkII. About .5mv is the lowest you would want on a MkII. | |
| Passive Preamps? Anyone? To find eight closely matched LDRs as needed for a balanced passive, requires measuring & sorting through many dozens of pieces. The task is much simpler with a single-ended passive. Only two matched pairs of LDRs are necessary for a two chann... | |
| Passive Preamps? Anyone? Clio, I acquired the LDR piece parts, but abandoned the project due to problems getting LDRs to track closely in a high-impedance volume control for a balanced tube preamp. I've been waiting on Unixman from that thread to complete a rather complex... | |
| who does mods for the Sony SCD XA9000-ES? BTW, if one were thinking about modding this unit, one of the first things would be to remove six silicon wafer AC rectifier bridges at lower left corner of image, and replace with custom Schottky bridges. Those $1 compromises in the critical powe... | |
| Help choosing coupling caps Construction of SIO is somewhat ambiguous, as Mundorf mentions both polyprop and metalized paper construction:"Our state-of-the-art metallised Polypropylen foils make it possible to maintain extremely exacting production tolerances that cannot be ... | |
| who does mods for the Sony SCD XA9000-ES? The main challenge modifying that unit is limited real estate to add things like aftermarket clock PCB, discrete dc voltage regulators, or alternative 2-CH output stage. It's really packed inside. But worth a call to Kyle at RAM to see if he has t... | |
| who does mods for the Sony SCD XA9000-ES? Why do you think modder would not? | |
| Passive Preamps? Anyone? He keeps a low profile; emailing him through that forum is probably the best way. | |
| Passive Preamps? Anyone? Incidently, toward the end of the above Lightspeed thread, Nelson Pass contributes schematics for a buffered passive that employs optocoupler resistors. I don't know whether he is currently selling product based on this design. My read is that son... | |
| Passive Preamps? Anyone? There is a long thread on DIY forum on the Lightspeed passive attenuator, which is sold commercially by georgehifi (indentified throughout the thread.) His design is based on optocoupler resistors, as formerly used in the Melos photentiometer volu... |
