USB connection to DAC: multi stage improvement

In my setup (Innuos Zenith Mk3, Antelope Zodiac Platinum with Sean Jacobs DC3/4 and Antelope Audiophile clock) sequential addition of decrapifiers has lead to increasing transparency, dynamics and soundstage depth.

My chain now reads like this

ZenithMk3->Singxer UIP->JHoinrich Isolator RH07b->IFi USB iPurifier3->LHY UIP2.0 Pro->Intona7054b->Zodiac Platinum

The Singxer is powered by Sean Jacobs DC3/4, The Lhy is reclocked by the Antelope clock

Of particular note: this is the best result of trying every conceivable permutation.

In terms of overall impact:

1. reclocking the LHY using the same clock on DAC and upstream Etherregen

2. introducing galvanic insulation after each powered device.

3. using isolator equipment with different chips at each stage.

i have learned the hard way that fighting ground level noise, RFI/EMI and other network noise is a gradual rather than binary solution at each step and that in digital audio ‘less is more’ doesn‘t apply as it does in the analogue section. Equally the whole bits are bits debate seems churlish against this background
