any suggestions on what to replace Bluesound Node 2i with

I used a Nativ Vita with Roon to a McIntosh C40 and an NAD amp.  Loved it - sold the McIntosh and NAD and bought NAD M33 w/ BluOS - - love it more - claims to be Roon ready but I haven’t been able to do that.  But integrated BluOS in the NAD along with Quobuz and Tidal are seamless and excellent sound quality.  I am proud owner user of often bashed but excellent and inexpensive Tekton speakers which certainly add to the sound quality of my system.  

 

I upgraded the board and PSU on my 2i. Used PD Creative in Poland, and an Allo Shanti LSPU. It added more transparency, more detail in the treble, more defined bass, but did slightly remove some of the warmth of the standard system. There was a slight bump in the upper mid range, but overall I really like it, and made a big difference. I am not using an external DAC yet. 

I went to my dealer's showroom to check out the Lumin T2 again and I am sold on it. Pricey but I think it will be worth the money 

I recently upgraded from the Node 2i to a Zen Mini Mk III (with LPSU), connected to a Pontus II DAC using a Transparent USB Cable. Very pleased with the results so far.

OP,

Earlier in this thread, it was posted that a reviewer posted (elsewhere) a list of  his servers recs at price points as follows:

1. Bluesound Node 2i ($550)
2. Innuos Zen Mini ($1400)
3. Innuos Zen MK3 ($2850)
4. Metronome DSS ($4200)

I can only relay to you my experience with the Zenith MK3 I’ve used for 6 months now.  It is my only source.  Qobuz.

I researched streaming quite thoroughly for a good three years—even speaking privately with a reviewer friend who has heard many well regarded streamers.  Part of the wait was me struggling with not only which one to buy but how much it was necessary to spend for me to be thrilled for the long haul.  I keep gear a long time but that is only possible if it performs beautifully and is a pleasure to use.  If I ever choose poorly, I will cut my losses and move on.  Not happened yet, thankfully.

But, two days ago, I heard a unit that a person employing a bit of hyperbole could say, “made mine sound broken”.  With zero exaggeration, however, such a delta in sound SQ would cost a lot.   Maybe as much as 50% more than my Zenith—considering the roughly $1350 or 50% price between Zen3 and Zenith3.  I’ve not heard the Zen, so I don’t really know the difference in SQ v Zenith.

The superior SQ was delivered by my own Zenith after installing the new Innuos Sense App to use instead of Roon.  On my system it is nothing short of gobsmacking.  Thrilled is an understatement.  

This tells me streamers/servers certainly can sound different or better.  Anytime prior to installing Innuos Sense had I done and in-home trial of a unit that sounds like mine does now,  I would have admitted the unit is superior to mine.  Period.  Not a close call.  Not subtle.  So, does the Metromme or Aurender or Lumin or Wolf or…..
unit at a similar price $4200-ish) sound as good or better than what I have now?  I wouldn’t know.  But you can….with seem effort.  Or you can go with the one you think is the best fit, like I did—if auditions are not accessible.  Some dealers would allow a MBG.  With no restocking fee.

So, shop your choices based on factors that matter to you.  I wanted appliance-like (simple to use), on-board ripping and storage with no DAC, along with top notch SQ.  Many other philes have much different priorities, but I assume all want SQ and a company committed to a long term relationship with customers.  I’ve listened to 3 podcast interviews of Nuno, a founding partner and design head.  Innuos seems to be very customer focused—expecting to have to earn long-term customer loyalty by offering stellar products.

I could not be happier.  But to contradict that statement, I actually will be even happier when I learn Sense better and certain features are added that don’t seem to be there now.

Good luck.  PM me if you have any questions.
