Start with Upgrade to DAC?

@mike4597 I have an Innuous Zen MK3 and I'm very happy with it.  I didn't buy it for the cd ripper, but I actually use it a fair bit.  Pop a cd in and it rips a copy to my library in under 5 minutes.  Real easy.

I use the Sense app by Innuous with Qobuz.  Assuming you would as well, I don't know if the convenience would be any different between Qobuz and Tidal. 

 I queried Schiit as to whether I would be able to detect a significant difference between the Bifrost and the Yggdrasil, and their surprising answer was "no." 

This answer maybe different based on who you spoke with at Schitt. I called them a few months ago to discuss the Yiggi+ MIB DAC. The guy I spoke to cursed out the Yggi+ LIM DAC that I owned and told me the Yggi+ OG was much better. I took his advice and got the last OG available (Schitt replaced it with the MIB). 

It took a month of burn-in for me, the same as what Robert Harley reported in TAS a few years ago. However, after that burn-in I could tell that the OG was much different than the LIM. Either could be preferred by people over the other. I love both and have then in 2 separate systems.

I have not heard the Bitfrost but based on my experience I described above I would think the MIB or LIM is much better than the Bitfrost. It would of course depend on the sonic match with your system and how revealing your system was.

I use a used $700 Sonore OpticalRendu streamer, which uses fibre optic cable (glass) just before it goes into a USB conversion and into the DAC. Not as pure a fibre solution as the Lumin X1 (owned it before) but close in execution.

Only issue with the Yggi+ DACs is that it sometimes shuts down for 1/2 second between songs on a ROON stream. That is if the next song is a bit slow to play. Irritating at first but the sound of the Yggi+ is so good that I do not care. Saved me $20k by eliminating my desire to buy the Playback Designs DAC.

If we can move back to the original questions about what might be suggested as the next area for upgrade of the poster's listed system, that would be enjoyable. I am new to streamers as of 2-3 years, having started with the humble Bluesound Node, third generation. Purchased new, still in play.

I was also stunned by having access to all the music available from streaming.

My best guess in looking at your system would be to get a dac that you might stick with for a while. The 2/64 got decent reviews, as did the Bifrost 2 before it. I liked my Bifrost 2 at the time, but the Holo bettered it. There are good choices if you choose to upgrade here. I am unable to say whether a dac or a streamer would make the most difference.

I've heard an Innuous setup briefly at a neighbor's house. It was very detailed. I have to return the book I borrowed, so that I might listen again. The speakers were two days out of the box and lovely.

This is supposed to be fun, remember.

@zarf I think the best bang for your buck streamer, especially if you use ROON, is the Sonore OpticalRendu. I have owned about 5 or 6 of them. I sold a few to friends and setup their streaming. I currently have 2 of them with both the audiophile power supply and the much cheaper power supply from Sonore. Go for the cheaper power supply.

Since I owned the Lumin X1 I would also highly recommend the following Lumin streamer based on the X1, but this one has no DAC.

LUMIN U2 (luminmusic.com)

That and the Yggi+ OG maybe a future setup for me. It sounds different than the Sonore OpticalRendu. I call the Lumin a wild child streamer vs the refined sounding Sonore opticalRendu.

Another streamer that would be perfect if it had fibre optical, but maybe great nevertheless, could be the

ARIES S1 - AURALIC

I say potentially great because my now sold Playback Designs STREAM-IF was great using SPDIF output from an Ethernet input. The Aries S1 also takes in Ethernet unlike the Lumin and Sonore, which take in fibre.

I tended to stay away from Ethernet streaming but the Playback Designs steamer was so good using Ethernet.

BTW - I should add that the digital Leedh volume control on the Lumin is almost as good as the great volume control on the Benchmark LA4 preamp. I compared the 2 side-by-side. The difference is really a non-factor for almost everyone. Normally digital volume controls are really subpar compared to an analog preamp, especially the LA4.
