Balanced or single ended leads from your arm.

Albert my comment was somewhat tongue-in-cheek. You will agree that your endosremnet of something other than Purist is an anomaly. Especialy since they cost less than the packaging Purist Cables probaly come in.

"Personally I prefer the..." All of us who know your system expected that sentence to end in Purist cables. I for one am glad you are not afraid to step outside the box.

re BAT balanced inputs:

When Viktor made that post in 2000 the VKP10's XLR inputs were not balanced and there was no advantage to using them. At the time Viktor did not think balanced from the cartridge was an advantage. I think the only balanced end to end phono stage was the FM.

Later on, maybe when the VKP10SE was introduced, the XLR inputs were balanced and Viktor recommended them over the RCA. I think now even the P10 is balanced end to end and maybe older P10s can be updated.

So somewhere along the line Viktor was able to overcome the disadvantage he stated in his AA post and make his phono stage balanced end to end.

I think Aesthetix may have undergone a similar evolution as I think they are now also balanced end to end.

One of the things Viktor's evolution means to me is that a balanced phono stage is not so easy to design and you might end up worse off.

George a: thanks for the update. I know when I went from a RCA input to XLR it improved-rather marked...not subtle. Anyway...thanks and good luck all.

Raul,
FYI, I wish my situation had been as simple as a poorly shielded cable. I tried numerous well-regarded and highly shielded single-ended cables and none of them eliminated the RFI. Balanced cables fixed the problem and improved the sound immediately.
So, perhaps my situation is rare, but it certainly doesn't hurt the argument to go with balanced cables when possible.
FWIW, I agree with your other comments about needing a well-designed phono stage to take advantage of balanced. I just wish I knew what reasonably priced pieces you think sound good. We all can't always "wait until we can spend more", as I've often seen you recommend. Regards,
Spencer

Dear Spencer: When I make the reference to you I omit to write that a not very good circuit/lay-out design could give that kind of RFI problems. Of course that balanced cables help in your specific case.

+++++ " I just wish I knew what reasonably priced pieces you think sound good. " +++++

The word " reasonably " is not a stand alone one because it depends on many factors like: which kind of quality sound reproduction do you want?, what music sound reproduction priorities do you have?, which kind of trade-offs could you accept?, what importance has to you the phonolinepreamp in the analog chain? etc, etc.
There are " reasonably " priced units from: 3K to 50K ???

Btw, very good system you own, specially those Merlin's ( I really like it ) and your analog rig.

Regards and enjoy the music.
Raul.
