Graham Phantom damping fluid level.

I use the spacer with my Koetsu RSP and also used it with the Black. I like it better than without. I wonder if anyone else has noticed this. I feel that the lower the damping fluid level is on the squared off portion, the better low and mid frequencies sound, however the downside seems to be that upper frequencies are somewhat compromised. Don't get me wrong, everything sounds great but I'd like to hear a little cleaner upper frequency response.

You need the VTA fairly negative as a rule of thumb on Koetsu. The back of the cartridge should be level. If you know Koetsu this indicates the front of the cartridge being tilted up or a negative VTA. This can only be achieved w. a spacer. The benefit of this approach is that you can increase the effective mass of the arm and the Koetsu (order a spacer in brass is ideal) will sound much better. I know, everyone is going on about damping. But that is fine tuning after everything else is correct. Get the resonant frequency below 12 Hz. I doubt anyone w, a Graham has done so if extra mass was not added. Once you get that done you will hear dynamics and bass. Until then, it will be much more congested.

I have found(even on the Phantom)that whenever I adjust fluid level,the VTA AND VTF should be atended to as well.It's a sort of Rubics Cube combo,but not really hard to do.You MUST become very hands on,and play around alot!
Best.

Has anyone tried contacting Graham Engineering? Last I called, the voicebox was full and email has been unresponsive. When I received my arm, it was SME mount and I wanted a template. I had to resort to buying a new armboard from TW for my Raven One.

Frank i found that if i lowered the tracking force just above the distortion point i get great highs. Then i adjust the damping level and it all seems to fall into place, great clean top end and monsterous bass.If i go to low on the damping fluid it becomes thin sounding .
