The emotional roller coaster of learning to love the THX Onyx dongle DAC

I recently acquired a pair of Vandersteen Treo CTs that made me reevaluate my whole audio set up. This is what I have learned about DACs and streaming:

I am a 99% digital streamer. Outside of the very occasional record spin, I use Tidal and occasionally YouTube and PlexDash for things not available on Tidal. My iPhone is the controller for almost my entire music experience. Thousands of selected tracks, dozens of playlists, and a pile of favorited albums.

I have been using Chromecast audios since they were released as my primary way of transmission. It works with practically any streaming service and at one point they cost $25! Optical output, USB power, pretty much an impossible product to beat.

Google being Google, decided to discontinue them and then did a horrible job of providing cast support for other devices, meaning you were alwyas having to use some garbage-ass app like DTS Play or Denons garbage app or Onkyos garbage app or Yamahas garbage….. you get the idea.

I’ve also noticed decreasing Chromecast reliability within Tidal. The cast function loses connection constantly and there is a kinda loud POP when you first connect.

I can hear, almost in unison, a number of people screaming “JUST USE ROON!”, But I am a cheap bastard at heart and I’ll be damned if I’m going to pay as much for a streaming app as I do for the rights to stream the music! I also have no interest in MQA or DSD, so Roon is an expensive solution to a problem that doesn’t exist for me.

This is an extremely long preamble to me getting to the damn point!

While tearing apart my entire back end system and pulling out every bit of amplification I own I’ve been doing A/B tests on every part of my signal path.

For the analog side, I had ended up with an Onkio M506-RS power amplifier and a Schiit Saga+ preamp. The Saga+ is set to full volume, and the Onkyo is attenuated to about 2 O’clock. This is basically as loud as I would ever, ever, ever want this setup to go. Anything beyond that is ear destroying audio violence.

After trying quite a few outboard DACs, integrated amplifier DACs, streaming boxes, and weirdo audio extractors, I settled on the THX Onyx.

I could go on for days about how it sounds “sweet” or “detailed” or how it has “slam” but is still “airy” or blah blah blah. We’ve all heard the cliches, I don’t wish to add to them.

The fact is the THX Onyx sounds superlative directly feeding my power amp. That’s it! My whole audio system consists of an old MacBook, a THX onyx, and a power amplifier. I have the Onkyo attenuated to about. 70% so I don’t go deaf if I accidentally move airplay to max volume.

To its credit, the Saga+ made literally no difference, which is kind of the point! In passive mode or in “active” mode I found no significant difference in sound across multiple audiophile tracks and test signals. If you need volume control and want a beautiful looking piece of kit, cannot recommend the Saga+ enough! I’ll be listing mine shortly!

So yeah, I figured I’m not alone in striving for that perfect sound and if you find yourself at a crossroads, I highly, highly, highly recommend getting an Onyx and some kind of digital source (any device with USB outputs will work, like a raspberry pi or windows PC) and hooking it directly to a power amp. The clarity and authoritative sound shocked me and have me priming my eBay and Craigslist accounts for a lot of equipment I think is pointless now.

I will post tomorrow with my comparison equipment, but I should say I have not used this thing for its intended purpose of driving headphones. Based on reviews most people seem to think it’s quite good at that too, but it’s staying in my loudspeaker setup for the foreseeable future.
 
I bought one of those WiiM Mini's, from Amazon, that are kind of the "new Chromecast" as I wanted to be able to use Tidal Connect to something as I hate having to be reliant on just a keyboard with the desktop app. So far, it's working quite well and I'm just using the built in DAC fed to my Carver C-1 preamp. It has toslink out but I didn't have another DAC to tie in but the WiiM does have the ability for 24/192 although I'm not utilizing that. I'm just using Tidal HiFi currently on a trial to see how the Connect would work. Overall, reasonably good and sounds quite nice.

I have had one of those in my Amazon cart for a while now, but I’m holding off as I am on the waitlist for their “pro” version which will have Ethernet and proper Chromecast support along with some other improvements. $150 and supposed to be released in the next few months.

I want the new Bluesound node BADLY for the eARC, but the internal DAC is trash and you lose volume control if using an external DAC. I can’t win!

Yeah, at that point, I'll just sell mine off and get that one most likely. For $92 shipped, it was worth a try. I can get a Node for cost but still don't really want to even spend that on one. Same goes with NAD and their preamps that have it built in or with a card. Just too much and not worth it to me. I guess that's an advantage of having tinnitus, if there is one; I can't hear the upper end differences. lol
 
Follow up:

I ended up getting a Topping E50 locally, just because I wanted to have a reference level, full featured DAC that had outboard volume controls and multiple input options.

Well, with my Chromecast Audio the E50 did great. Running in DAC mode and using the CCA for volume control I was happy as a clam, but I kept running into disconnection issues with the CCA and had it go to full volume unexpectedly causing me to nearly **** my pants; thank god I have my power amp attenuated!

So, I grabbed a raspberry pi I had lying around and put Volumino on it. Turns out the E50 can’t adjust volume with Volumino and I’ll be damned if I was going to use that garbage E50 remote, so I grabbed the Onyx and I think I’ve found my final streaming solution.

Does everything I need from Spotify to AirPlay to tidal connect. Also, between the Pi and the Onyx the whole thing can quite literally fit in your pocket!

So, if you have a raspberry pi lying around or can get one easily, this is a stupendous streaming combo that I don’t think can be beat, especially for the eBay price of the onyx and a used pi.

PS my Pi 4 didn’t have usb-c so I bought a four pack of usb-c to usb3 adapters for $8 on Amazon. No issues, and was recognized immediately.
