1. not experienced this myself but seen loads of bands play with the Kemper through the a Cab, plus heard endless reviews by people who have claiming it sounds amazing and "you cant tell its not the amp that was profiled". 2. Cab removal is spot on and easy to, press the "Cabinet" button to toggle it on of off. Its certainly not guna be artificial. 3. I saved money and bought the Non powered version to go direct if need be but Kemper added a new feature in the newer firmware updates called "pure cabinet" which is assigned to knob and co be manually set anywhere from 0-10 and this is the amount that it simulates a real cabinet sound. The more you have it set the more AIR and Feeling you actually get in the sound if going direct. So going direct works brilliantly now. This is an additional setting ontop of all the Cabinet tweaks you can make (High sound, low sound, character etc). Loads of tonal shaping. 4. Kemper for home use is stunning and all you would ever need for practice and recording. Means you dont need a cab at home which can free up space. Also it comes stock with profiles of the amps your talking about, except the Pod but even they are available on the exchange bizarelly. In most instances the Kemper can take a average sound and actually make it better, so alot of the HD Pro profiles are better sounding than the actual HD Pro. 5. Ive had it now quite a while, and also own no amps now to profile even If I wanted to. (I sold the tube amp I had to fund the Kemper) and it doesnt depreciate the value what so ever. Especially with how many amps are available to download Free on Kempers Rig Exchange and also the paid for studio packs of amps.
