Ground Hum with Rega RP6, Exact and TT PSU.

Thanks lenmc2964. I will try that and will play with it this afternoon. I absolutely love the sound of the table but as I mentioned before when I buy something it is supposed to work, period. I encourage you to do some research before you decide to upgrade. My trusty 28 year old Linn Axis never had this issue with the exception of when I turned the volume all the way up I would just heard the normal hiss. I am aware that I will never play this at full volume sine my Krell Amp puts out 250 watts per channel. If you do a search on Google you will get a lot of complaints in regards to noise and some folks just think that Rega knows about this problem and won't do anything about it. My system is fully balanced from preamp to power amp, cd player and it is ultra quiet with a dedicated line going to it. The Aragon 47 K as a separate power supply and I will try to move it as far aways as possible to see if it will alleviate the problem but I highly doubt it since it seems like it is an issue with the table's design.

Best regards to all. 

Thansk for all the responses. The Rp6 like all Rega turntables does not have a ground cable and after doing some research i have read that this is a common problem with these tables. Sfall mentions to lower the gain which It is already done. I had the table here at home on loan for about 10 days from my local dealer and I did notice that there was some hum but not as bad. Something happened after that period? Don't know. What makes the whole thing worse is that when I turn the tt psu on the noise increases as the tonearm gets closer to the spindle or where the motor resides. I will try moving things around but space and placement in my rack makes it difficult. Best regards to all. 

I hear you johnk. I think that I have buyer's remorse. I totally agree with that the sub platter is not all that great but once you put the platter on top it has lots of inertia. I think the tonearm is very good. I was talking to my wife and wished that i have never sold my Linn Axis which was DEAD QUIET after 28 years of use. The Rega does sound better in my opinion and I will give it a chance. I am also considering doing the incognito Wiring upgrade to see if that helps. I will talk to the rep and my dealer to see what they say. 

lenmc2964. I will try what you suggest however I have learned in my life that if something works keep it and do small improvements. I listen to a lot of classical music and there are soft passages which you can hear the hum a bit more. I am also disappointed that you have to hold the tonearm lift mechanism otherwise it drops too quickly and it tends to jump into the track and not from the beginning. AARRRRGGGHHHHHH.

Thanks Theo. Could you be a little more specific using an alligator clip?? I just unplugged the right channel and nothing changed. I talked with the folks who do the incognito wiring upgrade and they said that it not a cure for the ground issue. I Have read nothing but positive reviews on their work and the guy is about 1 1/2 hours from my house. May consider it however I will talk with my dealer first thing on Tuesday when they open. Thanks again you all.

Thanks Sfall. I understand where you are comig from, however I would not blame my dealer (at least not yet). He was very gracious to let me keep the table for about 10 days about month ago and I think that it was just a matter of a scenario in which I did not check the tonearm pushing it closer to the spindle. Again at moderate levels is not intrusive since I am using a 250 watt per channel Krell amp and I will never turn it up to the max level of 5:00 pm.  I also checked the wiring in the cartridge and it is absolutely correct. I am obviously dissapointed that the darn thing is doing this. Both my wife and I are professional musicians and absolutely love the way the table sounds and we find  it very musical. More so than my old Linn.  I am willing to take small steps and worst case scenario exchange it for something else. Will talk to my dealer on Tuesday since they are closed tomorrow. Thanks again for your input and happy listening. 

I am not sure about the issue with the Exact having 7 mv. My old Signet had an output of 5.5 MV and never had that issue. I actually tried it at a higher gain and it just got louder with ZERO hum therefore I don't know if an extra 1.5 MV would cause this problem.  To me it is obviously an issue with the table/cartridge. Thanks again for everyone's opinion. I just want stuff to work and not have to change a bunch of other equipment which works just fine. Best regards to all.

Thanks Les, Steve and Toddverrone. I appreciate everyone's input however the solution to put aluminum foil on a brand new turntable and cartridge at almost $2000 should not be an option. I have seen the video where the guy connects a cable to the ground wire of the PSU. I tried that and nothing changed. Keep in mind that the hum is still there even though the PSU is UNPLUGGED, disconnected from the table. Basically NO ELECTRICITY going anywhere. I plugged the phono preamp power supply on another outlet with an extension cord and far away from the table and  still there. My dealer will be coming by the house to check out the issue in person. He contacted Rega and they said that there is a problem with my equipment (BS).  Thanks for your replies and patience. More to follow. 

Forgot. We are thinking a defective cartridge.

Will do lenmc 2964

Thanks Bruce. Interesting info regarding the shielding around the motor. 
lwall22. Interesting comment in regards to the tiny ground wire around the tonearm. I may do the Incognito upgrade which uses a dedicated ground wire. H Rega; your tables sounds great, but you should fix this issue. 

Greetings again.

After trying everything discussed lately there is a chance that I will return the table and exchange it for something else. My dealer has been very gracious through the whole process and will take the table back if needed. He even stopped by my house this morning and agreed that the hum is unacceptable. We have exhausted every possible scenario and even one of his RP3 in the store hums using an Elys 2. 

As I mentioned earlier I really like the sounds of the table and with music playing you don't notice the hum even during quiet passages. My wife who has an incredible ear also loves it.

As far as their design some folks complain that you can not do a lot of adjustments and since I have a Rega cartridge this remains a non issue. If I decided on another cartridge there are shims available to adjust the VTA. 

The questions remaining are: Do I like the table enough to deal with the shortcomings  or look at something else??

My dealer's other options are Music Hall, Project and The Marantz TT-15 S1. The latter sounds fantastic and it's pretty much a Clearaudio with a very expensive cartridge and tonearm. 
The other two can be purchased in packs or super packs depending of the table/cartridge package. 

I would keep it in the same price range and here we go again. 

Anyone has had experiences with the models above?? I have read lots of positive comments about the Marantz and I am looking for musicality not HI-FI jargon. Thanks again for your patience and comments.
