| Killing sibilance distortion - VPI & Jubilee I am wondering if you know of any surefire path to nail sibilance, IGD and tracking without spending a massive amount of money.Now I here that Doug found his arm can pass the IGD trick.Must be Doug's alignment skill, yes :-)Nope. FWIW, here's my e... | |
| Killing sibilance distortion - VPI & Jubilee Also, VTF can't be optimized by using a scale. It can only be optimized by using your ears. I doubt that's the cause of your problem, but you should experiment to learn how your cartridge behaves with varying amounts of downforce. Whatever you lea... | |
| Killing sibilance distortion - VPI & Jubilee Goatwuss,Great information. As others said, you get A+ for diagnostic thorough-osity. The zenith photo does appear to have been taken from an off angle relative to the null point, so we can't really assess your zenith angle. As Axel said it looks ... | |
| Cleaning smaller records I knew there was a reason I bought a Loricraft! | |
| Supex SD-900 MKIV impedance loading IN THEORYMost LOMC's going into most active phono stages sound best with input impedance at about 25X the internal impedance of the cartridge, + or - 50% depending on the system. So, if Viridian's figure for your Supex is right, your starting poin... | |
| Loricraft and power cord upgrade? I run my PRC-3 over the frequency sweep tracks on the Cardas LP once a week. Helps clear the cobwebs out of the vacuum tube... Classicjazz, did you cable cook the power cord before this experiment? You can't be too thorough. | |
| Voltmeter for azimuth adjustment? Read Rushton's post on this thread . | |
| Killing sibilance distortion - VPI & Jubilee I'm pretty certain it will be further in with the original VPI alignment.Good prediction. If VPI's alignment is a single null point, as I think Downunder implied, or if its two null points are more closely spaced than Baerwald, that's guaranteed. ... | |
| Killing sibilance distortion - VPI & Jubilee One more thought: try increasing the space between the wires coming from the cartridge clips as much as possible. Spread them as far apart as you can without dragging on the record surface. Probably won't help with the sibilance problem, but may l... | |
| Killing sibilance distortion - VPI & Jubilee I've tried quite a few things, including different cartridges, and VTF, VTA and antiskate settings, but the sibilance is always there.Sounds like a clue to me. Let's apply Occam's razor...With all you've tried, why are you still assuming the probl... | |
| TWL mod for Rega RB600 arm---help needed Will,The weights need to be wider than the nuts, so you can drill them out to a snug-ish fit. The fit doesn't need to be exact. I super glued mine on and they worked great.The wire thingy is what Joe referred to as "Paul's adjustable VTF tweak", i... | |
| VTA setting for 'parabolic' and 'elliptical' styli Raul,Just kidding about "madness". You're right about organization and discipline. The longer you do this the easier it gets. Record keeping makes it quick and practice makes your ears better. Like Dertonarm we usually adjust without even thinking... | |
| VTA setting for 'parabolic' and 'elliptical' styli Raul's memory of how Paul and I play is correct. This craziness is not mandatory, unless your name is Doug or Dertonarm or you have Paul's ears.We write each LP's optimal arm height on a sticky note on the record jacket or sleeve. Setting height f... | |
| Servo Controlled Arm Sorry to the OP for my generic response, not related to his arm. I read "servo controlled" and assumed we were discussing a linear tracker. "Servo dampened" would have clued me in to googling first. Thanks to Hiho and Kirkus for addressing the rea... | |
| Servo Controlled Arm Heh! If avoiding skipping were the only criterion for tonearm performance, virtually every tonearm would be a contender. ;-)The theoretical problem with servo control of a tangential tracking arm is that, by definition, correction doesn't kick in ... |
