late to streaming, recommendations?

Welcome to the streaming world, @argonsteele. It is great to hear you have bridged the gap between your analog roots and digital convenience, especially now that Spotify natively supports bit-perfect lossless audio.

Here is what that "192" number means, along with the most logical, highest bang-for-the-buck upgrade path to make your streaming setup rival your turntable.

What "Sampling Rate 192" Means

The 192 kHz you are seeing is not the speed of the music coming from Spotify. It is the speed at which your computer’s operating system (Windows or macOS) is forced to output audio over the USB port. [1]

Because the standard Spotify desktop app lacks an "Exclusive Mode" feature, it does not bypass the computer’s internal audio mixer. Your computer takes Spotify’s lossless stream—which is encoded at CD-quality (44.1 kHz)—and mixes it with system notification sounds, upsampling everything to 192 kHz before sending it to your Cambridge Audio DacMagic 100. While it sounds good, your computer is doing unnecessary mathematical processing on the audio file. [1, 2, 3, 4]

The Upgrade Path: Maximizing Bang-for-the-Buck

To get closer to the organic, effortless sound of your vinyl and tube gear, you need to eliminate the computer’s noisy processing.

1. Ditch the Computer for a Dedicated Network Streamer (Best Upgrade)

Computers are packed with noisy cooling fans, switching power supplies, and background tasks that inject electrical noise into your USB cable. A dedicated Wi-Fi Network Streamer replaces your computer entirely. It pulls the lossless data straight from your router and uses Spotify Connect, which allows Spotify to stream directly to the hardware while you use your phone or tablet purely as a remote control. [1, 2, 3, 4, 5]

• The Budget Pick: WiiM Pro Plus. It offers an incredibly clean digital output, a stellar control app, and native Spotify Connect support.
• How to connect it: Plug the streamer into your wall, connect it to your Wi-Fi, and run a Coaxial or Optical digital cable from the streamer into your Cambridge Audio DacMagic 100.

2. Clean Up Your USB Signal (Alternative Low-Cost Tweak)

If you absolutely must keep using the computer, the operating system’s audio mixer is degrading the audio.

• The Fix: Look into player software that allows you to route Spotify through an ASIO or WASAPI Exclusive audio driver. This forces the computer to output a true, untouched 44.1 kHz stream to your DAC, changing the sample rate automatically to match the source file. [1]
• The Hardware Tweak: Use an isolated USB cable or a minor USB data filter to block the electrical noise riding along your computer’s USB power line.

3. Try a Free Trial of Qobuz or Tidal [1]

As a vinyl lover, you appreciate mastering quality and space around instruments. Even though Spotify now offers lossless CD quality, services like Qobuz or Tidal offer high-resolution masters (up to 24-bit/192 kHz). More importantly, their desktop apps feature a native Exclusive Mode toggle. This instantly bypasses your computer’s mixer, automatically switching your DAC to the correct native sample rate without any software trickery. [1, 2, 3]

4. Upgrade the DAC to a "Ladder" (R-2R) DAC (Future Phase)

Your Cambridge Audio DacMagic 100 is a great starter unit, but it uses a standard Delta-Sigma chip, which can sometimes sound a bit analytical or "digital" to vinyl enthusiasts.

Picked up the Lumin U2 mini today!  :-)  working great but still dialing the sound in.  just ordered a audiograde usb cable.  

I was about to recommend Lumin as I’ve been happy with my U1 Mini for years.

Enjoy!

Some really solid advice here. 

I will share some additional pointers that might be helpful. 

- First thing is to isolate your audio streamer rig from all the noise on your local data network. Many ways to do this. Essential to clean up as much as possible. 

- Minimize as much as possible any CPU processing at the Streamer/Endpoint stage. That means using Roon or another remote application to do all the heavy processing. 

- Don’t use Tidal connect or similars at the Streamer/Endpoint stage or it will increase ground noise variability which automatically creates jitter. Best to do that all in a remote computer/server. 

I just finished writing an article on a $50 USD Nanopi Streamer that was used in the T+A SDV 3100 HV DAC. This DAC costs aprox. $38,000 USD. 

Here is the article on the streamer. There are other articles to islolate your data network from the audio streaming system also for very little investment. To make them truly world class solutions, you will need to spend some good money on the power supplies. I use supercapacitor power supplies and have not heard a better streamer at any price. 

The NanoPi Streamer — A $50 Endpoint That Competes with the Best

It's all about isolation and power supply like any other component I guess and some streamers do it better than others. Innuos streamers aren't cheap but they are excellent.  There's a clear audible difference amongst the Innuos line-up.  I went from a NAD all in one streamer/DAC to a Cambridge, and then to a NODE, then a Lumin,  then an Innuos Pulse and now an Innuos Pulsar.  Both the Pulse and Pulsar are fantastic but the Pulsar takes music to another level.  But I have my eyes on an Innuos Statement NG. When you have reference components you want a reference streamer. Many people will tell you that all streamers are alike but that can't be further from the truth.
