| question about VirtualDynamics Reference PC One further comment. In all honesty, I don't see any value in obtaining these voltage measurements, at least for the power cords. I'm not familiar with the specific conditioners, so I won't comment on them. But aside from verifying that the cords ... | |
| question about VirtualDynamics Reference PC Thanks for the clarifications. I couldn't find any information on the Fluke 1711, but I'm guessing from your description that it is ac powered, rather than battery powered (correct me if I'm wrong).I would also assume that as an ac voltmeter it wo... | |
| question about VirtualDynamics Reference PC Some questions:1)What two points are you measuring the "ground voltage" between?2)When you make this measurement, is the power cord connected to a component?3)If so, is the component connected via interconnects to other components?4)If so, do the ... | |
| Your experience & thoughts on SSDs for MacMini 03-07-11: PerrewI still kind of fail to see what the SSDs do for sonics, are they having lesser electrical noise?If the music data is being output from the computer directly into a dac, via usb or firewire or s/pdif, it would certainly seem concei... | |
| Your experience & thoughts on SSDs for MacMini 03-07-11: PerrewI thought regular HDDs did sequential (what most programs do) loadings faster than SSDs?That was true in some cases a few years ago, but no longer. As a rough ballpark, I would expect a typical SATA2 SSD today to provide sustained ... | |
| Whats on your turntable tonight? Zaikesman, thanks very much! You are correct on all counts.My enthusiasm for vinyl has recently been revitalized by the retipping Peter Ledermann of Soundsmith did on my vintage Grace F9E Ruby cartridge. It is simply fabulous, although it's hard f... | |

| "Light Loading" Amps - Music Refence and others... Hi Ralph,Based on a quick look at the schematics at HHScott.com, it appears that the only Scott amps that used 6BQ5's were the 222A and 222B integrateds. The 222C and 222D used the generally similar 7189, as did the 299A and 299B integrateds. This... | |
| SET pre-amplification? Thanks for sharing.Did you provide some sort of low impedance load at the output (e.g., 8 or 16 ohms), to prevent the possibility of damage to the output transformer and/or output tube from inductive kickback in the transformer?Best regards,-- Al | |
| Lightspeed Attenuator - Best Preamp Ever? That has to be the lowest capacitance if any cable - no?The extremely low capacitance results from the flat construction with wide spacing of the conductors. 300 ohm antenna twinlead has similarly low capacitance.The lack of shielding could be a p... | |
| "Light Loading" Amps - Music Refence and others... Michael (Swampwalker), the "1" and "2" suffixes are applicable to tube amps only. "1" indicates that the grids of the output tubes are always negative. "2" indicates that they can go slightly positive, causing grid current to flow. That in turn re... | |
| "Light Loading" Amps - Music Refence and others... Roger Modjeski: The only loss (from light loading) is about 20% of the power rating or 1dB.Hi Paul,As we had discussed some time ago, this statement by Roger strikes me as incorrect for most amplifier designs. I have no way of knowing how correct ... | |
| Do you leave your components on 24/7? You'll find this thread to be of interest. IMO, the conclusion expressed by Cathode in his post dated 2-8-11 is the best possible answer to this perennial question:Depending on what kind of gear you have, how it's designed, and how you use it, tur... | |
| Lightspeed Attenuator - Best Preamp Ever? Paul -- Yes, that is exactly correct IMO. Although some might raise minor quibbles about the use of the word "ideal," because there will always be a limit to how severe a load a given buffer can handle without its performance degrading. Best regar... | |
| Lightspeed Attenuator - Best Preamp Ever? As I see it the 10:1 rule will be of no importance if all of the following conditions are satisfied:1)The output and input impedances that are involved are both essentially resistive, and do not vary significantly as a function of frequency. That ... |
