So think about these potential problems at twice before investing in such an equipement.

I shall describe all its internal components and their characteristics, as well as features to check with care. But don't be offended by the ham telling you that you have a big mouth, because there are some good objective reasons in using such a power. Going up from 100 W to 1000 W PEP, the power ratio is 10 and looks high if not huge.
Basics considerations are universal and can of course be applied to all other models, working in HF, VHF, UHF, whatever, doesn't matter, with the exception that in centimetric bands, high power entail new technical constraints on electronic components and wiring systems. As said some Old Timers, you might answer to this people, "you know kid, the live is too short for QRP, go QRO ! But knowing that you add only 3 d B each time you double your power, 1 k W output produces only a 10 d B power gain on the S-meter, what is not really important.
But I have never said either that an amplifier might replace a defective antenna. Do never use a high power to compense the poor performances of an antenna.
This is indeed the best way to create QRM or get serious troubles if your installation (cabling system, SWR-meter, power supply, etc) is unable to sustain such power, thus high currents. Improve first your antenna system in reducing the ground effect, use a low loss coaxial (RG-213, Belden RF-9913, Aircom, etc), try to get an excellent VSWR on the line, as much features that, once optimized, will increase the efficiency of your installation. If your transceiver last stage is badly matching your amplifier input specifications, you have all chance to burn your P. The Kenwood TL-922 amplifier for example must be driven with an input power ranging from 80 to 120 W PEP, no less no more.
On your side you hear them all, not always loudly, but at least 53 or with a strong intelligibility or QRK. For the same price or even cheaper, it will be more useful to improve performances or your transceiver and antenna than using a linear amplifier.
If you really experiment problems in working far stations or pileups although you are using efficient gears but at first sight not so performing as expected, in this case the last thing to install beside your 100 W PEP barefoot transceiver is well a good amplifier, up to your class limit, 400 W, 1 k W or more, depending on your national regulation. In all cases adding an amplifier to your current installation will probably not help you much in working far DX stations that arrive 53 or not at all to you.
However your QRK will be much improved and your correspondent will have please to hear you in better conditions, mainly if you work with a directional antenna, in which you can concentrate all your RF signal. Ameritron AL-1200X, QRO HF-2000, Kenwood TL-922, etc) removing the cover we are often impressed with the design, the few components but how big, the care and finish of the work brought up to the band-switch and cosmetics.
All high-end k W amplifiers display big, strong and rugged accessories, large coils, big capacitors, heavy toroidal transformers, big choke, for short all is big and seems to offer an excellent quality.
Depending on the design, it may have one or more additional active components providing bias, switching or even a receive pre-amplifier.
