| ELP laser turntable - any comments? Thanks NABS. I think the Minus K low profile (4-inch) platforms run about $2800. Payload capacity is a little over one hundred pounds for the low profile models, but goes up to 700 pounds with standard models like the BM-1 (which I think has a lis... | |
| ELP laser turntable - any comments? From a spec point of view, the Minus K passive isolator should be able to go head-to-head with the Halcyonics. The Minus K achieves 50 dB isolation at 10 Hz compared to the 40 dB of the Halcyonics. Also, the Minus K has a 0.5 Hz resonance, and the... | |
| ELP laser turntable - any comments? Eldartford, see patent 4,870,631 on www.uspto.gov - that might answer your question about whether the ELP laser turntable senses rate of change or if the output is proportional to displacement. If I understand the Abstract correctly, it appears to... | |
| ELP laser turntable - any comments? The Minus K vs Halcyonics would be a great test! Interestingly, they are based in Menlo Park, only a stone's throw from me (in San Jose). I'm wondering if Halcyonics would be open to providing a loaner for the test.What's the Halcyonics cost? I ne... | |
| ELP laser turntable - any comments? Albertporter - does the weight of the Walker include the air isolator? Or is the 400 lbs just the platter/bearings/plinth/tonearm/motor? If you replace the air isolator with the Minus K isolator, you will probably strip out a lot of weight (and wi... | |
| ELP laser turntable - any comments? The Minus K products are based on their patented Negative Stiffness Technology. From a physics point of view, the spring equation is F = k * x, where k is the "spring constant" or "stiffness". Minus K gets their name because they have found a way ... | |
| ELP laser turntable - any comments? The Minus K BM-1 has 0.5 Hz Horizontal and Vertical resonance, whereas the BM-6 has higher resonance frequencies. The BM-6 is like an air table (but without the air). The BM-1 is unlike anything else when it comes to isolation, outperforming prett... | |
| ELP laser turntable - any comments? The BM-1 comes in a version that supports up to 700 lbs. I have the 150BM-1 (up to 160 lbs) which is enough to hold my 75 lb Yorke + 75 lb granite surface plate.But, yes, the BM-6 is only rated up to 105 lbs.I'm wondering if Minus K can customize ... | |
| ELP laser turntable - any comments? http://www.minusk.comI use the BM-1.The Minus K vibration isolation platform outperforms air isolation by a factor of 10-100x. Air is fairly "stiff" (which is why it works well as a bearing, like in linear tracking tonearms and some of the high-en... | |
| ELP laser turntable - any comments? I apologize in advance - this is a long post...I absolutely have kept the Yorke S7 - love it. I added a Clearaudio Syncro to it, which improved things. The Minus K vibration isolator is amazing - if you thought the Vibraplane was cool...To answer ... | |
| ELP laser turntable - any comments? I've lived with the Laser Turntable for nearly one year now, and tested it like crazy against my reference system (Simon Yorke S7, SME 309 with damping kit and Graham IC-70 phono cables, Lyra Helikon SL, Minus K vibration isolation platform).First... | |
| Morch DP6 and vertical damping - pros & cons?? SirSpeedy, is your pal YODA interested in selling his Air Tangent (if he hasn't already)? | |
| Equipment Set-up Recommendations? I use a Minus K BM-1 isolation platform. This is an industrial product - isolates about 10x better than a Vibraplane (or any other air-based solution), and even outperforms 5-figure industrial active isolation solutions. In fact, the Minus K BM-1 ... | |
| Subwoofer Amp Recommendations I have 5 Kenwood L-07M amps driving Revel F30s, M20s, and a C30. The F30s are providing reasonable bass for now (no subs yet). The monoblocks with short 1-meter Kimber 8TC cables deliver power and speed - and the cable layout is pretty clean compa... | |
| Fi magazine master index available? Does anyone know when Fi magazine ceased publication (ie. what was their last issue)? The last issue that I have is March 1999 (Vol 4, Issue 3). |
