What innovative, unconventional cartridge designs can you recommend?

I meant digital dumps a lot of noise back into the earth paths via the power cord.

That's why having any digital equipment on a separate line from the mains board can help, even though ultimately the 2 earths come together at the mains board.

I would agree with your comment about focussing on minimising noise from your own equipment, logic tells me you can't control the incoming power, but you can address issues in your own gear. Getting rid of noise in your own gear is no different to upgrading components, lower noise - more resolution, at a much lower cost.

Interestingly I have used the Naim system power protocols with my amplification - all on one line, power amp first into the wall then preamp then head amp. My distribution box is daisy chained, not star earthed - I've compared the two formats and the daisy chain  with power amp first in to pre to source wins every time. This system has worked well for many high end installations I've done with primarily  non Naim systems. That Naim protocol system has removed mains noise from other non audio sources very effectively. I also make sure the house earth is in good shape, no corrosion, decent wire etc.

I don't like mains filters per se, they tend to suck dynamics. I used to distribute high end years ago, so I've done many installs.

You encouraged me to pull out Bruno Walter conducting Mahler 9 with the Columbia Symphony.  This is a box set I've owned for around 60 years.  While the performance and sound quality are superb for the era, my copies have very bad surface noise, especially Record 1 which contains the first and last movement.  Designed for autochangers, Record 1 gets put back in its sleeve twice as often as Record 2.  The sleeves were paper with a plastic lining, replaced with anti-static sleeves after an ultrasonic clean.  As a box set, the records were much freer to slide around inside than records in normal record sleeves.  This surface noise is not the snaps, crackles and pops I associate with static - more a subterranean murmuring or leaves rustling.

Before my DS Audio cartridge arrives, I will ultrasonically clean these records again, and then listen to see how much noise the optical cartridge transmits.

I have a couple of SACDs of Mahler 9 - the Osmo Vanska BIS recording A$30 and Gergiev's complete set with LSO live which costs about A$60 for 10 SACDs.  The Walter / Columbia set is still available on CD for about $30.  All these disks added together cost less than one Achromat here.

Yep. It was removed about as quickly as you removed that Lian Dung cord  from your new Soulmate. 

I love Bruno Walter’s Mahler. I have a CD of 5th with NY Philharmonic that I consider one of the best interpretations of that symphony. I have it ripped onto the SSD drive and I listen to it once in a while. It’s probably as noisy as your box set records. But it doesn’t interfere with the powerful delivery. I think the noise is in the recording in this case and unfortunately it’s unlikely that the DS audio cartridge will significantly reduce it. The line contact stylus might help some. Worth every effort including the additional US wash cycle. 

@audphile1 

Yes, your rave about Bruno Walter set me off!

I already have micro-line styli in both my table/cartridge systems, so I don't expect any improvement from that.  I did not go with the cheapest DS Audio cartridge, because I wanted at least a line-contact stylus.

PS: did you manage to unpack "acacia missing identity"?

@richardbrand 

Acacia mistaken identity?

Yep

And bought Bruno Walter’s Mahler 2nd  with NY Philharmonic on discogs. My first purchase there. VG+ rated and looking forward to hearing it on vinyl. Hopefully the incoming Humminguru will make it more listenable. 
 

Your DS cartridge is DS003 correct?
