Opinion on oracle tonearm
Please view the picture of the gimbal bearing Oracle arm.http://www.diyaudio.com/forums/showthread.php?s=34e5da99b761b666564929311f701c1d&postid=861098#post861098 
TT/Tonearm/cartridge interaction theory?
The arm wand material is a consideration also. Steel, aluminum, and carbon fiber tube arm wand may have resonance characteristics of dragging a metal/hollowed tube on a rough surface. Solid or small diameter wooden arm wands have lesser resonace/r... 
Teres, Galibier and Redpoint
I used a Technics SP-25 as a motor to drive a VPI TNT Jr. platter. The turntable and the motor turns about same speed 33RPM. The pulley on the Technics is about 11.8 inch so the belt tension is much lighter than normal turntable motor which is abo... 
String suspension vs. uni pivot or gimball tonearm
The vinyl play back started over a hundred years ago. It was just over 20 years ago, the Well Tempered arm was patented. I only guested that Mr. Bill Firebaugh realized that it didn't require much energy to keep the tonearm stable enough to track ... 
String suspension vs. uni pivot or gimball tonearm
I think string suspension tonearm is more susceptible to speed fluctuations either from belt slippage or speed control feedback problems. The speed fluctuation causes the arm to resonate and may be even skate due to more degree of freedom from the... 
Luxman PD-121
I filled the cavity around the tonearm and empty cavities inside the turntable with damping material. I also replaced the plastic armboard the solid wood. This helped the turntable sound warmer with improved musical definition. 
Luxman PD-121
It looks like a uni pivot tonearm. You can adjust the cartridge azimuth by turning the out rigger nut locating left of the tonearm pivot. I have several PD 121 and I like the SME series III arm on them. I also have the Infinitive Black Widow tonea... 
RB300 tweaking problem
Is there a noticeable sonic differences with the cartridge damping trought? Thanks 
best phono preamp for Art Audio Symphony II?
I use Sonic Frontiers SFP-1 phono stage with Denon 103R with my Art Symphony II with volume control. The music sounds natural and relax. When I like better sound stage and focus, I used my Sonic Frontiers SFL-2 preamp with the amp. 
art audio volume control
I have an Art Symphony II with volume control, ALPS, 50KAX2. The music sounds more natural, loosey, and relaxed. When I connect my Sonic Frontiers SFL-2 preamp to the Art amp, I get better defined image and focus. The Art volume control is just a ... 
Art Audio Carissa with Volume Control?
I have an Art Symphony II with volume control. The music sounds more natural, loosey, and goosey. When I connect my Sonic Frontiers SFL-2 preamp to the Art amp, I get better defined image and focus. The Art volume control is just a variable resist... 
Graham tonearm tweaking
As you observed, fluid level, the VTF and VTA affect the sonic quality. The tough music passages on the record put more pressure on the stylus than lighter passages. Therefore, the correct setting for complex music passage may not be desirable for... 
Graham tonearm tweaking
I like to offer my school boy explanation. The fluid level is critical because it affect the sonic energy resonates and dissipates from the tonearm. For bearing tonearms such as gimbal and unipivot, the bearing friction is critical. Remember your ...
