It substantially improved my sound (due to the ADC I now use for my phono stage - to input into the nanoDIGI - and the 4x Topping E30s that handle the 8x output channels).

So my signal chain is:
* phono stage --> ADC (kit from Uwe Beis, running at 96kHz)
* ADC output plus 3x digital devices (CDP, DAB+ tuner and TV box) --> 4-way digital source selector
* digital output from the source selector --> nanoDIGI 2x8
* nanoDIGI --> 4x Topping E30s
* Topping E30s --> various power amps driving:
- a sub
- bass panel
- mid panel
- 3 ohm true ribbon, on each channel.

I don't use a series cap on the ribbons as the amps driving them does not produce a thump, on turn on/turn off.
