If i wanted to connect it to two different computers, is my best bet just a simple usb 2.0 switch / kvm?
For home office audio configuration — unless you have need to keep everything in digital domain* — I highly recommend an
Ashly LX-308B Mixer as an "integrated pre-amp"**. That provides 8 stereo input channels (TRS Balanced or TS SE), and 2 stereo output channels (1 TRS Balanced/TS SE, 1 TS SE). The volume trim can be adjusted individually for each source channel to level the respective input volumes (or for gain staging); and then the combined total output volume is controlled by the master out.
The primary advantage is that all channels to remain active, instead of having to only select a single source at a time like typical AVR (or KVM device). Though you can still easily mute any / all channels as needed. This way, I can have both my work laptop and home computer hooked up, while also listening to music from any source I want at the same time. I never miss any "beeps" or "rings" from the computers; and when someone at work "rings" (e.g., an incoming MS Teams call), I simply pause the source music or push the channel mute button as I am answering the call.
Input sources:
1) Work Laptop (straight audio out or cheap USB DAC or decent Topping E30), 2) Home PC (USB DAC Topping D90*), 3) Squeezebox v3, 4) Turntable, 5) Oppo DVD (2 channel), 6) Alexa Input, etc.
Output targets:
- Balanced: RME ADI 2 PRO FS which then provides balanced out to KH120A speakers; and Coax SPDI/f output to KEF LS50 W II.
- SE: Monolith THX 887 (* the balanced output from Topping D90 also route here for "straight passthrough")
* For my use case, there is no audible difference from an added AD/DA cycle routing through the mixer since all digital components have high quality DACs. And an all digital mixer doesn't help much since some sources are analog only (i.e., turntable).
** Plug for Tim F. at Dale Pro Audio — he reduced the price from $899 to $575. That said, if you have fewer sources, you might instead look at a lower cost "desktop size" mixing board (Behringer, Yamaha, Mackie, etc.); but for me, most of those added frills and I just wanted a simple straight through analog audio paths.
Rather a few years.
