Shielded power cord best used on Digital/Source or on Tube Amps?

@lak  Thanks for all your input here.  I just ordered some Furutech FP-SO22N cable and some Furutech FI-28M(R)/FI-28(R) rhodium plated copper connectors to build a cable for my DAC’s linear power supply, based largely on your recommendation and my experience with another manufacturer’s nano treated cable products.

I really like Nanotec products, but they don’t make shielded power cables.  When I moved my Nanotec #308 Power cable from my DAC’s LPS to my receiver and replaced it with a shielded cable of lesser quality I liked some of the changes with digital playback, but a large amount of the magic went with the #308. There is a lot of wire - both analogue and digital - behind my equipment, and shielding digital power cables seems to make some sense for my application.

Given the wire formula is similar between the Nanotec #308 and the Furutech SOXXN series wires, and given your description of FP-SO22N performance matches my experience with the Nanotec power cable, I thought I would take a swing at the shielded Furutech wire.  I will report back on my findings.

A final note, I am also a huge fan of Furutech connectors.  They are like audio jewelry, very well built, and seem to function and sound at least as good as advertised.  I notice that their mid and high range connectors are routinely used on pre-made cables costing $1,500 and up.  The cost of the wire and connectors for my DIY shielded cable is about $300.

@knownothing, although grannyring reported very good results with the Furutech wire he is now making a power cord that he said outperforms the Furutech wire. I personally have not tried it and I don't see an ad from him for the power cord on Audiogon but if you were interested you could always send him a personal message. I'm just trying to keep the thread current since you posted to it.

Yes indeed the new Duelund 12 gauge Polycast 600V wire with Connex carbon fiber barrel and rhodium plated over pure copper conductors is better sounding after burn in. Cost is $165 shipped for the parts.

Thanks for the updates.  After two weeks the shielded Furutech FP-SO022N cable is sounding pretty great on the linear power supply for my DAC.  Strengths are midrange tone, dynamics, elaborate and convincing soundstage, and very clear and tuneful bass. Surprising also is the improvement in timing, more toe taping pace and rhythm.

Now I am looking for a power cord for a tube phono preamp power supply.  What are your current recommendations for that?

@knownothing, I'm glad to hear that you like the Furutech FP-SO022N cable. That cable works very well on all front-end equipment, therefore, you could go with a second one as it will work very well.
However, it was me I would suggest you go with grannyring's suggestion of the Duelund 12 gauge Polycast 600V wire with Connex carbon fiber barrel and rhodium plated over pure copper conductors. You could use this power cord in either of the two locations (or any location) and you might find that you like the sound of the Duelund 12 gauge Polycast 600V wire better than the Furutech FP-SO022N.
