Narrowed Down My Choices; Opinions Welcome

In my search for a used integrated amp,  between $1K - $2K, and without the ability to audition them personally, I've narrowed it down to a few that should be of sufficient wattage and current to drive my efficient (93db) 4 ohm speakers. Your opinions are invited. The candidates are:

Hegel 100 (120w/ch)
Parasound Halo (165w/ch)
Wyred 4 Sound STI-500 (250w/ch)
Rogue Audio Sphinx (100w/ch)

Just so you know, the efficiency is not quite as high as it appears.

The sensitivity of your speakers is 90db/1m/1w or 93db/1m/2w.

Take a look at my post on your other thread.

I'm not familiar with these amps, but I would think any of them should be able to drive your speakers.
