Do upgraded LAN cables/purifiers/switch box make a difference. What is recommended, if so?

As I upgraded my dacs and streamers over the years I found audiophile switches and filters that used to “improve” sound were no longer needed. With my last three dacs, Mojo Audio Evo Pro > Tron Atlantic Signature > Cinnamon Audio Galle,  I found I could sell off these devises.  Going from the Innuos Zenith mk3 to the Pulsar and finally to my current Cinnamon Audio Galle streamer made the need for these devices melt away. The Innuos Pulsar paired  with the Mojo dac is really where the need for these devices ended for me.  Before this I found expensive switches and filters from companies like Network Acoustics and Paul Pang quite helpful and sonically pleasing. 

I actually found most of my “tweaks” were no longer needed selling my Puritan conditioner among other accessories.  The only “tweaks” I currently use are the Verifi Swiss Digital Fusebox and Exemplar Audio Portals.  I find both sonically beneficial.   

I still find ethernet cables make a nice difference.  Same for USB cables, perhaps even more so for me.

I’m a big fan of Fidelizer Audio.  Keetakawee is on a mission to engineer excellent and affordable SQ.   Great customer support!   

I’ve owned his AirStream for years.  It’s been working flawlessly.  I also used his Pro software before switching to a dedicated streamer.   No experience with the Hyperlink or Nimitra.  His most recent products are the Erawan Flagship and the Lira.

For the last few years, I’ve been tweaking for EMI.  My observations are here & here.

Also, @gournard  

In late September, I crewed 10 days on a Cal 34.  San Francisco Bay → Monterrey → Channel Islands → SF.   A steady westerly at 22-24, gusting to 35.   Just a single reef on the main.  Plenty of whales, dolphins, sea lions, otters, etc.    I love the recent navigation apps.  Don’t miss Loran-C.  

Congratulations on fixing up your cottage.  Leaky is a sailor’s bane.  I suspect that you did a shipshape job.    New adventures await.    4 months in the Caribbean on a Vision 444 sounds absolutely heavenly.*   The last time I was in St. Lucia, greenies (Heineken’s) were only US$.50/bottle.   Aaaah - those were the Jimmy Buffet days!   Yes, I’d be interested in a crossing.   PM when you know more.

*Probably a good idea to stay well off the coast of Venezuela.

My journey summarized:

Started with an English electric 8 switch and Network Acoustics Eno filter. Was unsure of any benefit. Thought there was, but it was subtle at best.

Auditioned a Nordost QNet and LPS. Was unsure of any benefit. Thought there was but it was subtle at best. Certainly not worth the significant spend.

Auditioned a Reiki Superswith and LPS. Brought an obvious and material benefit this time and decided was worth the significant expense. So much so, I’ve actually considered their $$$ network cable. Deferred for now.

My conclusions summarized:

Some of this gear works, some does not. Audition is a must.

Stick with companies who specialize in a particular problem as opposed to companies straying from their core competencies.
