KEF LS50 Wireless Internal vs External DAC ??

I am finding my KEF LS50 Wireless to sound warmer, fuller, and more spacious, with better resolution of image location, when running my streamer (Audio Alchemy DMP-1/PS-5 power supply) to Audio Alchemy DDP-1 DAC/Preamp into its RCA inputs (which are then internally converted via ADC and again DAC) than I am running my streamer direct to the speakers via USB.
Given the numerous redundant conversions at play, I speculate that the ADC conversion is so much more transparent than I imagined and that the internal DAC in the KEFs is so much worse than I expected that I would recommend others use a high-quality external DAC with these speakers (even if they are to be internally re-DACed within them). 
Anyone have this experience?? Thoughts??

If I wanted a great system that dominated the LS50W in a small room and wanted to retain Roon and streaming, I’d go:

Silverline Minuet Grand
Pro-Ject StreamBox S2 Ultra
Pro-Ject PreBox S2 Digital
Exposure 2010S2 Power Amp

To keep it simpler you could replace ALL the electronics with the NAD C368. You could also do a PrimaLuna Prologue power amp if you want to include tubes in the system (you’d want something a touch warm to offset the prebox digital’s extreme resolution). Either way, the Silverlines are sensitive enough to make that a very tempting proposition.
I really appreciate you taking the time to provide your opinion. I’d be inclined to look into the Silverline Minuet Grand if I could exceed LS50W performance on a budget with a $900 NAD C368. I assume you have heard these speakers? Do you think the difference uptick would be subtle or fairly dramatic? How so? I listen to many different genres of music. Will the Silverline knock it out of the park with everything I want to listen to? I do love the sound I’m hearing from LS50W but I’m also concerned about reliability and that if one thing goes inside of it my whole system is unusable. Well that and the miserly 1 year warranty. If the active parts had a 5 year warranty I’d probably stick with LS50W and call it a day. Thanks for any additional guidance you can provide.
Hi Julius, happy to help. What are your digital sources? That’ll really help me answer your question. Are you streaming from a computer and/or TV, or will your stereo be more self-contained? Once I know, I can make a more informed suggestion.
Agreed! Apologies for the poor web etiquette. I think we have established consensus earlier, though, that the rca inputs on the ls50w are often preferable to the usb, even with digital sources. As such, why not just use a passive speaker, provided it has a well designed crossover and other strong performance metrics?
