Thank you for saving me countless hours researching through this forum, very decent, Levi!A few recent major upgrades
upgraded to handcrafted RCA coax cable from Darren of Arctand.com in Singapore
upgraded to handcrafted DC cable from Darren of Arctand in Singapore
implemented @cdacosta 's idea of replacing BNC connectors with zip-tie for direct contact with my ground box cables (on the only 4 connection points in my system that either weren't already directly connected or using the nice solderless Furutech clone RCA connectors)
implemented @cdacosta 's idea of using small Rochelle salt bags parallel along the ground box cables (component side)
implemented @cdacosta 's idea of using small Rochelle salt bags inside components (used 3 small bags in various spots in my Schiit Wyrd USB enhancer device and 3 more in my Kenwood Integrated stereo amplifier)
The biggest difference was from Darren's DC cable. This brought about much improved dynamic handling, detail and with further extended bass and great soundstage. This is actually my 4th DC cable from him and each time I noticed unwavering sonic perfection, solid in every aspect from FR to weight, delicacy, purity of tone, you name it. Unfortunately with the culmination of so many upgrades I was also hearing more treble detail, being taken so much closer to the truth of the recording. Finally just hours ago I went ahead with a few small bags of Rochelle salt inside my Wyrd USB 'decrapifier', on capacitors, tiny bag directly on the PCB board and another on the input power section. This was the magic bullet for me!!! Now songs that were too harsh are suddenly delectable - luscious, delicious with immense detail, soundstage, impressive PRaT and bass quality, very lifelike realism, and just as detailed as before but without harshness! Massive sonic advance in all! I do want to remind a lot of the improvement is also thanks to the LHY OCK-2 external clock with thick BNC cable as well.
The RCA coax cable from Darren replaced a highly tweaked Odin 2 silver digital RCA coax cable from Aliexpress (I added 2 ferrite chokes, spiral-wrapped copper-foil shielding and replaced the connectors with solderless Furutech clone RCA connectors from Aliexpress). I actually still have yet to do another A-B comparison but Darren't cable is certainly supreme, and it's even the cheapest of his 3 versions, at around the same price as the Odin 2 from Aliexpress. The DC cable actually replaced another of Darren's DC cables of the same type, but I had this one made with different connectors in order to avoid 2 extra adapters in the former - this improved things in every area of sound. At least the 2nd biggest improvement came from CDA's suggestion on the ground box thread for a direct connection to spare BNC ports of a ground box cable with the bare wire on the outside of the connector secured with plastic cheap zip-ties rather than the crimp method low quality conductor BNC connectors I found on eBay. Those FWIW made an impressive difference back in the day, but this was a whole new level of realism and downright fidelity! The small Rochelle salt bags also mentioned by CDA on the ground box thread made a more subtle difference in my solid state amp, but a better improvement in my USB purifier device, actually darkening things up a bit to make it overall more linear again. Highly recommended to try all of these!
Which other PCs and digital coax cables have you compared to Darren's ?
