| TriPlanar Tips Hi JB0194,While the example I gave was for power amplifiers, the same does indeed hold true for any conventional (non-digital) power supply design.Since my turntables are batterey driven, I haven't had to chase down power supply filter issues. I'm... | |
| TriPlanar Tips Dear Paperw8,Your point about people blowing more time and money is absolutely spot on, and it is work like Doug's in understanding the gear he owns that adds to the volumes of information on this forum.At your leisure, take a look at Doug's posts... | |
| TriPlanar Tips Dear 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 (relatively) heavy tro... | |
| TriPlanar Tips The damping trough is becoming a vestigial device, as I've yet to run a cartridge on this arm where I prefer it with damping.I think it's smart for Tri-Planar to continue to provide the feature, as there's no telling when a cartridge will crop up ... | |
| Changing from an XV1-S What's been lost in this conversation is the subtle but (to my ears) significant changes that the XV1s has undergone in the last year - benefiting from the development of the XV1t.I don't want to get into the better/worse discussion on these two o... | |
| Dynavector XV-1s loading question. Tuning - reminds me of one of my other loves - guitars.As it applies to analog, I recall an instance at a music shop where the mother wanted to return the guitar she bought for her son ... because it was out of tune!Fortunately, our analog front e... | |
| Dynavector XV-1s loading question. Oooo ... wait a minute! I re-visited items 1 & 2 (resonant tank circuit).The formula for resonant frequency is given by:res. freq. = 1 / [2 * pi * sqrt (L * C) ]. I believe this is the net capacitance, but what I'm not clear on is whether the ... | |
| Dynavector XV-1s loading question. Jonathan, Ralph ... thanks, as always, for jumping in. You always force me to get back to the raw numbers that always explain what I'm hearing.I think the best we can hope to accomplish, in advising our customers, is to outline the general princip... | |
| rumble issues - see old thread update Hi Doug,Thanks for the clarification on your Sorbothene implemenation, as well as the validation that locating it closer to the source component is a non-starter.Cheers,Thom @ Galibier | |
| Dynavector XV-1s loading question. Thanks Palasr,As usual, a brilliant post from Jonathan. The last paragraph bears re-reading, and explains very concisely the reason this is all so system dependent.Amen, brother Jonathan!Cheers,Thom @ Galibier | |
| rumble issues - see old thread update Tom,I was just pointed to this thread. There's too much good inforamtion to sift through at the moment, but based on the names of the posters, along with a quick scan, it looks as if you've received good advice.I likely missed some of the finer po... | |
| Dynavector XV-1s loading question. >30 is the right answer. In most systems, the number has been in the 100-150 range. In some rare configurations, I've found 35-50 works best.Now, with my Atma-sphere MP-1, I am running wide open (no loading resistors). Just when you think you h... | |
| VPI bearing oil/grease? All,Remember, that in the case of inverted bearings ... well, they're upside down.It's been a long, long time (20+ years) since I've had one in my posession, and the issue of lubrication didn't come up.Typically, inverted bearings have some sort o... | |
| VPI bearing oil/grease? Hi all,Some good general principles were laid out above. In general, youre balancing out two parameters against each other: bearing play and damping. Theres no hard and fast rule. In addition to the local parameters within your control (your tur... | |
| Changing from an XV1-S Hi Peter,In case you haven't been on this thread http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1278338549&openfrom&63&4#63, our Schroeder Reference / Talea tonearm comparsion in my room at this year's Rocky Mountain Audiofest is sh... |
