Anything going on this month? 
Preamp for Pass
I use an ARC SP-15 with a Pass Labs X350 and MIT cables throughout. This ARC preamp has a 200 ohm output impedance and the Pass 22 kohms input impedance. The ARC manual says 20 kohms min load recommended. Seems like a good match. From a listening ... 
HELP-woofer moves alot when playing lps
Isn't analog playback fun? The old adage, "Ignorance is bliss." holds true. Just like an onion, we peel back the layers just to find more layers. Cartridge alignment, cartridge tracking, VTF, VTA, suspended turntables, rigid turntables, high mass,... 
The Audiophile's Wife
Very enjoyable reading. Your wife articulates what many wives must be experiencing. I had a pair of speakers in the late 80s and 90s that my wife loved. Couldn't care how they sounded, she loved how they looked. It has been 10 years now since I so... 
Are you an Audiophile?
Anyone who listens to recorded music is an audiophile. Some just spend more money on equipment and software than others. Some take it more seriously than others. 
What time do you wear?
I have owned an Omega Seamaster since 1994. In early 2001, I was living in Germany and it started losing time so I took it to a jeweler who sent it back to Omega Switzerland for an overhaul. It cost me just 400DM ($200) and that included new hands... 
Cartridge Loading and Compliance Laws
Picture the stylus like a wheel on a car. The stylus has micromotion as it tracks the groove on a record and that motion is absorbed by the suspension. Just like the wheel on a car moves over small bumps in the road but the car remains fixed. In b... 
Cartridge Loading and Compliance Laws
Lighter screws are definitely better because that mass is at the farthest point from the pivot. So that affects the inertia of the tonearm. Aluminum screws are preferred for both less weight and the non-magnetic properties. Don't use plastic screw... 
Cartridge installation
The process taht Daverz describes is the exact same that I use. The other nice aspect of the SME Arm is that once dialed in, it stays. 
Cartridge Loading and Compliance Laws
Question 1: The eff. mass is a product of the counterweight mass (plus the overall arm mass)and distance squared from the pivot point. So increasing the counterweight mass increases eff mass, yes. Increasing the counterweight mass and then moving ... 
Cartridge Loading and Compliance Laws
When we talk about tonearm effective mass, we are really talking about inertia. And when we talk about cartridge compliance, we are really talking about spring rate. Not to sound confusing, but high compliance is low spring rate and low compliance... 
Cartridge Loading and Compliance Laws
Good point. When talking about effective mass, we are really talking about inertia and the moment of inertia is proportional to square of the distance from the axis of rotation. So, yes, more counterweight mass closer to the pivot will reduce effe... 
Cartridge Loading and Compliance Laws
Correct, if the tables are turned, then you are out of luck. The only choice is a new tonearm or cartridge. Some might say dampening the tonearm would help, and it might. Only thing is, dampening is masking the underlying problem. There still migh... 
Cartridge Loading and Compliance Laws
One more twist to the plot is that the cartridge specs may not be accurate to real world application. eg. the compliance of the cartridge may be given at a high frequency point and could be much different at low frequency. My SME tonearm convenien... 
All Amps Sound the Same....
Perception and reality come together if one of the two condtions are met:1. Two or more people agree on what they saw or heard.2. The President of the United States says it is so.
