Perhaps we need to address those aspects then?
Please do describe in detail your system.
Pc model and cpu, ram
Operating system
Tascam drivers (if appropriate) installed.
Are you using the Tascam setting panel?
If Windows what is your buffer setting
What cpu loading is Reaper reporting during recording
What audio interface device settings do you have in Reaper
If you import a known good media audio file into a Reaper project and play it how does that sound?
I am not a Reaper expert by any means but forum members will find these aspects (maybe more or less) important to take the question further.
From what you write it seems that there should not be any analogue clipping but you can get similar distortion if digital bits or words are dropped. For example a struggling computer can make a "noise) if a buffer is too small usually just clicks as parts are missed but can sound chopped if lots of the data is missed.
You have normalised to make the noise more noticeable. What level is it prior to normalisation?
More, when you used the alternative interface did you also change the power supply unit?
It might seem that non of these questions help at all but for me there are too many variables and unknowns to help at this stage. Someone else maybe a user of that interface and/or have better ideas!

System Detail:
Macbook Pro
macOS Mojave version 10.14.16
Processor: 2.4 GHz
Memory: 4 GB 1600 MHz DDR3
Performance meter says CPU 4.6-4.7% usage during recording with the Tascam interface Electric Guitar Direct In with 1/4" cable.
Audio Device Settings:
Audio Device: Tascam US 16x08
Request sample rate: 48000
Request block size: 512
Unchecked Box: "Ignore running change notifications"
Checked Box: "Allow projects to override device sample rate"
Unchecked Box: "Allow use of different input and output devices"
Known good media audio files appear normal and show level change in the master output when played YET no sound is produced in the headphone output.
Levels prior to normalisation are -35 db.
Yes I have tried with a separate power supply unit and the results have not changed.
I am more than thankful for your suggestions and I feel like I learned something anyway regardless if this helps. But again Thanks!
