You can get really good USB mixers for less than you paid for those cards. If your going to analyse reverb and effect then you need a card with multiple channels as any analysis will fall foul of clock drift on multi card setups. I like alan just use good quality electrets on a preamp but spunds like something more professional and robust might be needed. I suggest you look at the prosumer home recording with a google for ‘multi channel usb mic mixer’ Read a couple of reviews. Latency is pretty easy to find as play spaced ‘tick’ from the output and record and load up in audacity to get a accurate latency. For a single pcie card Creative Sound Blaster Z High Performance Gaming Sound Card < $80 and also include a really good beamforming microphone. Depends what you want to analyse if room impulse is a thing then you want several mics on several channels with something like the 4 channel prob being what you need. Creative is more of a gaming thing but prob cheapest single with mic that is really good quality and you will know the mic is matched to the hardware and has a dsp app that may be something that will of much interest.

Being tied to a PCI(e) slot is an awful nuisance these days. Many machines have multiple USB busses, try putting the sound card on a bus without much else if there's a problem. I'm not sure if your application is closer to a language lab or speech recognition. Startech is generally a good company, you can also get these cheaper and faster through Amazon. https://www.startech.com/en-us/search?search_term=usb%20sound I also have a few Chinese clones bought through Aliexpress that seem to work fine for general playback and recording. Preamps aren't just gain but supply operating power to electret microphones. I do amateur nature recordings with home-built 4 transistor preamps and generic electret capsules, maybe $5 parts cost total.
