| TriPlanar Tips 08-30-10: DougdeaconDan,Thank you for asking, I appreciate it. You'll find the answer in my last post, dated 08/27/10. I haven't posted since as it would be fatuous to contribute to a discussion after explicitly asking that it stop.I've got to say... | |
| TriPlanar Tips You are on the right track with this tonearm resonance issue. It is very much a result of the amount of energy a cart is allowed to impart back into the arm. This is not only a function of the compliance, but also the damping of the cartridge itse... | |
| Whest ps.30r Dcarol:Thank you for the review. As you noted, the PS.30RDT is a pretty good phono stage, so your comments are quite interesting. Just out of curiosity, what gain level are you using? | |
| TriPlanar Tips Since it takes so little time (less than the duration of a cut on an LP), remove the trough and try a practical observation. It's pretty simple to do.The trough is attached to an arm. The arm attaches to the tonearm by a screw that is not accessib... | |
| TriPlanar Tips Here is an equation that I found to estimate the resonant frequency of the cartridge cantilever:rf-c=159/sqrt((eff_mass-t+mass-c+mass-f)*(compliance-c))rf-c: resonant frequency of cartridge cantilever (Hz);eff_mass-t: effective mass of tonearm (g)... | |
| TriPlanar Tips Tapping on a Rega to find resonance points is one thing, tapping on a Triplanar is plain foolish and will not reveal the differences in nuance that these tips address. The vibrations created at the cartridge are entirely different from the vibrati... | |
| TriPlanar Tips 08-28-10: Thom_mackrisDear Paperw8,You went to the effort to quote my comment about the the THIN BAR to which the trough mounts, and then conveniently side-stepped my point by IGNORING this bar and turning your attention to the trough itself. The ... | |
| TriPlanar Tips 08-27-10: Dougdeacon... ultimately what counts is whether a person knows what they are talking about.Agreed. In this case the measure is how music sounds with and without the trough. We know. You don't.The OP requests that you avoid further postin... | |
| TriPlanar Tips 08-27-10: Thom_mackrisWe can discuss issues of rigidity until we are all blue in the face. Would you say that the thin bar that supports the damping trough is more rigid than say, a ... tuning fork?I won't speak about all tuning forks, but the tin... | |
| TriPlanar Tips 08-22-10: Dougdeaconthe publication of suggestion #6 here is what inspired Tri-Mai to add that small, threaded VTF weight. You apparently got one and your gratitude is duly noted!The fact of the matter is that I do appreciate that you contributed ... | |
| TriPlanar Tips Jfrech:When I tap on the trough, I hear a *sound* but a sound is not necessarily a resonance. The sound that I hear when I tap on the trough quickly dissipates. Now, you can impart a lot more energy upon a tonearm part with your finger (or a screw... | |
| TriPlanar Tips 12-06-09: Thom_mackrisYes, you have to unmount the arm to remove the trough, and yes you want to remove the support bar. The idea is to eliminate a vibrating tuning fork. You'll be removing two small, straight slotted jewelers' screws.From my pers... | |
| TriPlanar Tips As to suggestion #6:6. For fine VTF adjustments don’t futz with the counterweight, there’s an easier way. Set the counterweight for the highest VTF you think you’ll need (ie, close to the pivot). Pick up some 1/4" I.D. O-rings from Home Depot. To ... | |
| Trade- off, power SS vs tube magic. The question with tubes is: "how would you like your signals to be distorted?" (I think most people refer to this distortion as "warmth") To that extent, if your interest is in tubes, then the only answer is that you have to listen to each amplifi... | |
| Anyone using a Lyra Delos yet? What is the significance of the output voltage level of a give cartridge with regard to audio fidelity? For example, the Lyra Delos cartridge puts out 0.6mV. Some MC cartridges that I have seen put out less than half that voltage level. The appare... |
