Streamer wanted

One thing that's never mentioned is that laptops run fine off of battery power.  No AC issues. For less than $1500 you can have a truly high-end Windows laptop, that is absolutely overkill at getting bit-perfect datastreams from network servers to an external DAC.

I have mine set to "continuously on," keep the lid shut (no display noise), run Windows remotely from a phone or tablet, and happily do Office, browse the net or social media while listening to pristine sound.  I've yet to be convinced that a dedicated streamer would improve the sound quality.  When I hear it, I'll accept it, but with fully balanced electronics and cabling, I turn the volume sky high and there's nothing but blackness from which stunning music emerges.

Audiophillia is centered on constantly improving the system, and I'm a full-fledged member, but getting digital data to a DAC is not endlessly improvable.  We may be past the point of solved.

Don’t waste your money... all you need is a cheap grace digital link...$159 Amazon. Most people cannot hear a difference between cd 16/44 and so called hi-res. Although the grace will do hi-res. Spend the money on an external dac. Even then, you need nothing more than the musical fidelity v90 dac, if you can still find one new, $299. Spending any more on either is a total waste of money, because none of it will ever sound like a quality recorded LP.

@electroslacker My Roon Nucleus was a clear upgrade in sound quality from a 15" MacBook Pro.  The noise floor that I wasn't even aware of with the MBP just dropped away.  I could never hear a difference between the MBP running on AC or the battery.  Further improvement occurred recently with the addition of an LPS.  I think perfect bits were being transferred by the MBP, as nothing in the music above the noise floor changed with the Nucleus.  Same tonality, dynamics, etc.; there was just more low level information: the tails of the notes, the hall, the squeak of the floor of the studio or stage, etc.

@audioguy85 The difference between Redbook and hi-res is quite audible.  I can also clearly hear the improvement of 192kHz over 96kHz when comparing albums with the same mastering.  Good 192kHz can rival or surpass vinyl, due to the lack of surface noise and the rock steady pitches of the notes, something that vinyl has a problem with due to off-center record holes.

@docknow I respect what you say above, and relate to your descriptions.  Makes me anxious to try some options.  I could see galvanic isolation keeping analog noise from propagating.   I've just been so impressed with the sound I am getting from FLAC data and Qobuz going through laptop to USB to DAC.  Thanks for sharing your experience.
