I’ve been following this thread with interest since I’d ordered a new streamer around the time it was first posted. I stream music via Tidal Connect and my existing chain consists of a third gen Bluesound Node (which, for the $350 price, cannot be faulted) connected via USB to a Holo Cyan 2 which then connects via XLR’s to my Hegel H390 and then onwards to a set of Boenicke W8SE speakers through Veritas’ Apurta speaker cables (great performers for the money).
I gave myself a $2K budget for a new streamer and settled on Holland based Magna Hi Fi’s Mano MKIII.5 streamer with its separate matching Farad 3 LPS. Magna Hi Fi offers several optional upgrades and, after bathing in snake oil, I opted for their offered upgrades on the connecting cable for the two boxes, a fancy pants fuse and LAN isolator from Synergistic Research. I’m disclosing these choices fully realizing it may elicit flack, but for me, it was in my $2K budget (just, at $1900USD) and rather than trying to take it with me, I thought I’d have some fun spending the money in the pursuit of audio happiness. I think their base case unit retails somewhere around $1,200 and can be upgraded thereafter if down the road, if curiosity gets the better of you.
At $1,900, I’d consider this at the low end of “expensive” in the world of pure streamers (units without dacs). The two boxes are matched and diminutive in size but once plugged into my system, and now connected via I2s (because, well I’m curious) I can say without question, it makes a difference.
I don’t know why or how, but am really quite stunned at the improvement in sound quality. Everything I stream sounds much cleaner, quieter and more detailed. Am now a big believer in the benefits of a separate linear power supply. Also, I'd note their Level 2 silver cable works really well in a system like mine, which already has plenty of warmth. Honestly, I would not have thought a streamer could make such a contribution to my overall sound quality but it's clearly a step forward.
I’m using the Volumio software (they offer several options) which is proving a solid platform for me. One downside, if you like to stream Tidal Connect natively (as I do) the optimal way to do so requires Volumio’s subscription service. Note you can stream Tidal via the Volumio software without the subscription, but to do so natively, via the Tidal Connect app, you need to pay the piper.
So the answer to your question, in my opinion based on my experience with the new gear I acquired is a resounding yes. It not only made a difference, but a pretty significant one. As always, YMMV.
