| Dynamic speakers for OTL amps Thanks a lot, and yes, I hope I am in for a treat! Obviously there are many variables, and doing away with x-overs may not be realistic in practice. The advice concerning a smooth impedance curve and bass excess/voicing is relevant, as are the mod... | |
| Has anybody heard the ProAc D40R???? I can just throw in some listening experience from a number of years ago, comparing the Proac 3.8 and the Dynaudio Consequence mk 2, both made around 1995-2000, using a Krell 2 x 600 amp. I found that the Proacs were lively and could play very wel... | |
| VPI motor - upgrade to 300 rpm? Mark, sorry for not answering. I am ordering a 300 rpm motor and a new pulley from vpi, with the lower groove 10 percent larger than the upper groove, for a silk string. The reason I do this is, mainly, slight speed or pitch variations. For some r... | |
| VPI motor - upgrade to 300 rpm? Mike at VPI has mailed that if I am able to extend the plinth hole for the pulley, he can ship the 300 rpm motor and new pulley. The hole for the 600 rpm motor is ca 35 millimeter, the pulley is 22. A half rpm motor means a doubling of pulley diam... | |
| Lyra Dorian vs unipivot tonearm I may be able to extend Dan_ed's point. I had a Lyra Clavis for a long time, in different versions, and then a Lyra Titan and Titan i. My experience was that the Lyra pickups did not work well with the parallell arm I was using (Souther in the Cle... | |
| VPI motor - upgrade to 300 rpm? Rubber belt alternatives - debatable?From my experiments so far, using nylon and silk thread versus rubber belts (vpi new grey + translucent original belts), it appears that rubber has a number of good sides, that are only with difficulty improved... | |
| VPI motor - upgrade to 300 rpm? Tonyptony, thanks a lot. I am a bit confused by looking at the Hurst and Elusivedisc web pages. From the latter it appears that VPI is upgrading towards the lower rpm hurst motors, and that the 250 rpm motor is currently the best regarding low noi... | |
| VPI motor - upgrade to 300 rpm? Mike at VPI writes that changing capacitors will make a difference to motor performance:"The 600 RPm motor should work perfectly when you get the capacitor right for your countries voltage and frequency, it is a critical item and if you are willin... | |
| VPI motor - upgrade to 300 rpm? I get quite correct 33 rpm (a tiny bit slow) by setting the SDS to 66.00 hz, the top value, and then position the player (or the Samas, but that is harder to do) so that the nylon thread gets a good amount of stretch. The thread is 1 mm thick. For... | |
| VPI motor - upgrade to 300 rpm? Wow, made it with the nylon string! Turns out I had to use more tension, and a double knot (with the knot at the outside of the span). The nylon thread/string creates very interesting sonic changes, the whole thing seem to be clearer the bass more... | |
| VPI motor - upgrade to 300 rpm? Storyboy, thanks a lot, it looks very effective. For now I am testing threads, one silk, one nylon, both ca 1mm thick. I can tension the thread by adjusting the player feet to widen the distance to the pulley. The platter starts ok and I do notice... | |
| VPI motor - upgrade to 300 rpm? Today I got this reply from Mike at VPI:"The 300 RPM motor does not work on the HW-19 so that is not an issue. The 600 RPm motor should work perfectly when you get the capacitor right for your countries voltage and frequency, it is a critical item... | |
| VPI motor - upgrade to 300 rpm? Thanks! I think PRAT is what I am looking for, and want to try the silk thread variant. What kind of basic knot do you use? The question remains, what is the best motor, is there a sonic profit with 300 rpm? Since no-one here has answered, I have ... | |
| VPI motor - upgrade to 300 rpm? Thanks for advice. First of all, my main problem was solved by oiling the motor and glueing the pulley to the shaft, as I wrote. It was not a drive belt problem. I use the SAMA with the SDS and have a special Bright star platform (sand box) with s... | |
| Three wheel drive for the hw19 With this suspension you may get a bit more rubber than air, it may not be fully optimal. Yet I enjoy the advantage. Now I can tune everything based on getting the spirit level 100 percent using my pump. A new experience. First impression, things ... |
