I was in the market for a DENAFRIPS Terminator II DAC recently. I quickly found a used one online for a decent deal. When it arrived, to my dismay, it didn't come with the (plastic?) feet. My understanding is that the feet are cone-shaped and fit the bored-out hole in an aluminum disk under the Terminator II chassis. It's typically the inverse, where the cone is threaded under the chassis and the feet are the disks. If you can't picture that, don't fret. Simply put, the unit I received was missing what I needed.
I contacted DENAFRIPS support, and they suggested IsoAcoustics, as many of their customers were satisfied with them. I was merely looking for an OEM-ish replacement for the ones that would have originally come with the unit; however, if they were recommended, I was enticed to take a look.
In the interest of a quick solution, I ordered four of the Indigo (16 lbs max per unit). It was a bit pricey, but I thought, could they make a difference? I can always return if I'm not satisfied with them. The first inspection shows that they are made of quality, heavy material. The aluminum is well machined, and the rubber feels like it won't degrade. Even though there are only three OEM feet, I spaced out the four in each corner for even distribution. It does the job well.
As for listening, there is no difference between proping the Terminator II on a book I was using while waiting for the IsoAcoustics to arrive. Some swear by the vibration isolation. My subjective listening doesn't reveal that. I can see how this would greatly benefit a turntable, in which vibration can cause the tonearm to skip, but not in other audio devices.
I think I'll keep them since they are of quality; however, I'd be cautious if you were purchasing them solely for potential audible performance on anything other than a turntable.
Have you used these? If so, did you experience any audible improvements?
