Lon, I did some reading in the past couple days and some Exact Carts were/are defective.  I don't know if that explains the relatively loud hum I have which increases as the tonearm/cartridge travels towards the spindle.

In reading, the distortion I have may be in part from tracking error and I plan on resetting VTF and Anti-skate/Bias before using the TT again to see if this improves things.  

I could easily live with the sound of the exact just not the Hum or distortion.   One way or another i want a TT setup that's without Hum and distortion....with or without the exact.  Mark.

Don't blame you Mark, sorry you're having troubles, hope you get them squared away.

Mark,

Great idea about resetting VTF and anti-tracking.  Also check the balance weight and the bias adjustment based on what the exact cartridge asks for.  My balance weight was a little heavy and was throwing off my cart.  I found as the stylus moved towards the center of the record pops and clicks occured.  I had a hard time getting my stylus to float just 1mm (pg 4 in rega p6 manual)above the platter to set this. What I thought was a mm was actually closer to 3 mm.  It was very difficult to see with everything on my p6 being black.  It took my a while to figure this out and was getting very frustrated thinking it was just the way it is.  I did experience hum and had to move my turntable away from the cable box and also keep the rega power supply interconnects away from various power cords.  Took me a while to figure this stuff out so I understand your frustration.
best of luck

JD

I haven't done any listening in two days.  I have 3 hours blocked out tonight to listen and try a few changes.  If moving the TT and re-routing cables in addition to resetting the VTF and anti-skate don't fix the hum and distortion, I'll take it to a dealer I've located in Dallas.

I'm also going to try the stock rectifier in the CSP3 to see if things warm up a bit with the HD800s with the Silver Poison cables.  I'll also do an AB comparison with the stock cable to try to nail down the differences.  Mark.

OK,  I couldn't wait.  Here's what I've done...put the stock rectifier in the CSP3...it may be my imagination but it does seem to have warmed things slightly.

I am using the Rega RP6 TT to ZP3 to CSP3 used with HD800 headphones thus taking both my Amps out of the picture.  I moved the turntable about three feet so now the center of the CSP3 is over 2 feet away from the spindle of the TT.  The ZP3 is on the floor and as far away as 1 meter cables would allow. I rerouted the power cable of the ZP3 and the wall wart of the Rega power box (which is on the floor) away from other cables and plugged them into their own Power Conditioner...the RSA Haley.  All other equipment is plugged into a  RSA Jaco Power Conditioner...CSP3, Taboo, Torii, Jolida 100 CDP.  I have also reset the vtf to 1.75 as specified by Rega.  The anti skate I have set at one as I had read that this might be better...I previously had it at 1.75 but anyone who owns a Rega TT knows, setting this is less than accurate and is said not to matter much.  Somewhere between 2 and 1 is probably OK.

Bottom line after all this effort?  Well, the hum with tonearm/cartridge increasing with movement toward the spindle is still as loud as ever and the distortion mainly in the left channel is too.  In addition since moving the CSP3 it is now above the ZP3 and seems to have made the hum from it louder...but I can live with that hum.  So I guess I'll make a call to the dealer and take the TT to the Doctor.  I hope it's as easy as putting on a new cartridge.  Mark.  

PS...I used Pat Metheny's "Water Colors" LP for the listening test.   Electric Guitar, Piano and wind instruments seem to cause the distortion.  Bass and Drums don't seem to cause the distortion.

Damnit, it DOES sound as if the cartridge is the culprit. Sorry Mark, hope no matter what is what it's settled soon. I know how you have to have your lps!

       If that is the Valve Art 274 B it isn't your imagination. I really like the sound of that tube. Any way hope you can get that cartridge squared away.

Good Luck



Cool
