| VPI clamping system design flaw? Here's an easier method. Try tapping the back or your fingernail on the edge of the record. At some point you will clearly hear that the record is completely "seated". too little or too much and you will hear the difference.Enjoy,Bob | |
| Who was your first Was into prog-rock, back in the 70's, so my first expansion into "jazz" was progressive. perhaps Return to Forever or one of those prog-jazz bands of the time. I know I litened to lots of things in that vein as I entered college and was exposed to... | |
| Antiskating .... The last analog secret There was a bit of discussion not long ago about how some arms use a progressive anti-skating mechanism. The theory was that you need more anti-skating as you get closer to the spindle, where the circumference is smaller on the record and there's ... | |
| 10 Levels of Turntable Mastery OK, lets see if I can pick up where Atmasphere left off:TML7: May not be able to fully set up a Linn, or address the vageries of voltmeter based diagnostics on azimuth adjustments, but certainly has real-world experience with multiple tables/arms/... | |
| REL subwoofer cable I know it's against audiophile etiquette, but I just coiled the extra length of mine. Coiling generally negatively affects high frequencies, but this should not be an issue for a subwoofer feed.Enjoy,Bob | |
| can a tube-o-phile be happy with ss? Tweaking? - that's why I have vinyl!!!Some SS amps provide the best of both worlds with a good tube preamp in front of them (aka McCormack's with the Rev A or better mods, but there are certainly others also).Enjoy,Bob | |
| Top Jazz Albums of 2008 Just got the new Roy Hargrove - Earfood disk a couple of days ago. This one should be on anyone's list of top disks for the year.Bob | |
| Subsonic Rumble Solutions Simpler is usually better, IMO. I'm even bothered by the idea that I would need a step up device if I were to get a LOMC down the road. Somehow I wonder if any improvement over the 20X-H (a very good cartridge in its own right) would be lessened b... | |
| Subsonic Rumble Solutions I have a Dynavector 20X-H cartridge on a Moerch DP6 red dot tonearm. Supposedly the correct tonearm for this cartridge (gotta love a Moerch, since you can buy and change armwands to match the compliance of the cartridge).I was listening yesterday ... | |
| Subsonic Rumble Solutions There's been a lot of talk about rumble and subsonics. How does one differ from the other?Another question about these little RCA filters - anyone guess what's inside them? They are sooo small there can't be much. The rest of the signal runs throu... | |
| Subsonic Rumble Solutions Hey, those little RCA "Sub Sonic Filter pairs" looks cool, and may well be worth trying out for only $29. There are 2 values: 20Hz and 30Hz. Both have a 12db slope to them - not very steep. So if I was looking for 3db down at 17Hz then the best ch... | |
| Subsonic Rumble Solutions And why, in God's name, would one ever run a beautiful analogue signal from a turntable through anything digital, unless they were forced to upon pain of being drawn and quartered? :-)I think I'll open a bottle of wine tonight and listen to someth... | |
| Subsonic Rumble Solutions I tend to agree with you Mapman. The less I have to put in the signal path the better I feel about it and the better the transparency/musicality. I would far prefer to find a mechanical solution that doesn't alter the rest of the sound, if possibl... | |
| Subsonic Rumble Solutions Hey Buddy-Bob 2, I can say with some certainty that the woofer pumping is there on most LP's to one extent of the other. But my ears feel like they are popping on some, but not all, LP's. If I turn the sub off on these I don't get that annoyance (... | |
| Subsonic Rumble Solutions I received a reply from Rod Elliott on my questions about his filter (see below):My question about using a lead acid battery or a laptop power supply: "The circuit is specifically designed to operate from a split (+/-) supply. While a single 12V s... |
