| Best Rock Albums in 2009, so far M. Ward "Hold Time". Just released and good on vinyl. | |
| Capacitor log Mundorf Silver in Oil Volleyguy, Tony Gee has a better handle than Tempo on how to rate caps. With Tony's method there is modest bracket creep. Caps that once led the pack at a 10 rating have been gradually surpassed by 10-20% improvements, raising the benchmark for SO... | |
| Improving your BAT 150SE Hi Semi, thanks for the acknowledgment & glad you are happy with those mods. | |
| Capacitor log Mundorf Silver in Oil Whatever one thinks of the Tempo review, I completely dismiss statements like A is 3x better than B relative to a 6x difference in price. This way of thinking has nothing to do with making objective assessments of high end andio products. | |
| Dodd preamp battery plays 40 minutes BTW, Ibex makes an inexpensive industrial-quality 1.5A 12V frame charger with a battery protection circuit that disconnects the battery from the load in the event that voltage falls below 10.5V. I would consider this type of feature mandatory for ... | |
| Dodd preamp battery plays 40 minutes Vinnie is certainly right about SLA batteries. To extend useful life, a 12V SLA needs to be topped off with charge as much as possible, and discharge below 10.5V (even for deep cycle models) will permanently weaken them. It has nothing to do with ... | |
| Review: Trans-fi Terminator II Tonearm After several weeks break-in of tonearm wire I made a few tweaks to set-up. Vic provides a custom pedestal mount with an off-set stud to allow the arm carriage to be positioned pretty much anywhere along the radius of the platter. By moving the ca... | |
| Periphery Record Rings The physics of a slightly off-center ring flywheel are complex. Even with the inner & outer ring perimeters shifting slightly, the majority of the ring's mass remains concentric. The net flywheel effect may still be superior relative to no fly... | |
| Periphery Record Rings Bob, I also have the VPI black delrin & lead platter. The thing that got me interested in the brass mat is how much better brass sounds than stock delrin in the feet of my TNT. Who knows how brass will sound coupled to vinyl-- though there are... | |
| Periphery Record Rings Hi Bob, we seem to think along the same lines... I may try their brass mat, based upon my recent positive experiences with brass clamps and bearing housings. At 3.5 lbs. the brass mat should contribute both to flywheel effect and to resonance cont... | |
| Why is some vinyl noisy? In this vein a couple albums in my collection come to mind, such as George Harrison's All Things Must Pass, and several Miles Davis Mosaic box sets with 7-10 disks. With the Harrison, I try to sit long enough to work my way into Apple Jam disk thr... | |
| Why is some vinyl noisy? After using a 16.5 for about ten years, I finally figured out that some records with such problems require a full 1-2 minutes cleaning per side with lots of fluid before they give up their clicks & pops. Perhaps worth a try. | |
| Sandbox-style isolation Scott, I agree that sand moves in all dimensions at the particle level to dissipate system vibration as mechanical energy. The issue is somewhat different regarding drive train stability: Will the segmented top plates migrate or resonate in the ho... | |
| Sandbox-style isolation Assuming that significant mass loading has been applied to minimize shifts of the segmented top plates in the horizontal plane, the heart of the matter would seem to be that vibration is conducted through dense adjacent solids--in this case, mecha... | |
| Sandbox-style isolation Thom, Segmented top plates sharing a single sandbox, each segment with an alumimum angle or aluminum heat sink anchored deep into the sand. Heavy mass-loaded plinth with heavy outboard motor. Do you really believe that the top plate segments will ... |
