I used to use Herbie's Tenderfeet (different types and sizes) and they used to work for me back when I first started in this hobby. As my equipment got more discerning and revealing, they tended to soften and muddy the sound so I just used the standard footers on my Marantz Reference gear.
On a lark, I tried the Isoacoustic Oreas and they made a very big difference in the focus of the sound from top to bottom. Nothing negative to report. As the focus improved, so did imaging, decay, ambience and all those subtle cues that make for better realization of what's in the recording.
The Iso-Pucks look like a less fancy version of the Oreas and did come out first, and are used by lots of recording studios for their monitors. They should work fine for your gear. Most places have a return guarantee as long as you return them in as new condition.
All the best,
