has anyone heard the nuforce amplifiers

Rgurney, not to steal Jwpstayman's thunder, but in my systems, the Nuforce seem to make it impossible to tune in weak stations when the Nuforce amps are powered up. I have two tuners in other systems on a different floor than the Nuforce system and this seems to be the case with both tuners. The NuForce amps pass RFI interference to the tuners. You can tune in "phantom" stations with average signal strength that are purely RFI noise from the NuForce. When you turn the Nuforce off, these phantom stations disappear. If you use the Nuforce in a system where you have an FM tuner, you can still get some of the stronger stations (as I do) but it's probably best to use FM in a different system and switch the NuForce off while listening to the tuner.

But the Nuforce do perform amazingly well in their price range, there's no denying that. Perhaps someone will come up with a fix for the FM interference issue. In fact, I will write to Nuforce and ask them about it.

The RFI problem is partially fixed by this patch

For some receivers, it will dramatically reduce or eliminate the RFI problem. We tried it on Sony FM receiver and the problem goes away. But for others, the problem is only somewhat reduce.
We'll let you know in a week. Meantime, we appreciate whether the patch works for you or not, email support@nuforce.com and let us know.

THe RFI problem does not affect pre-amp or other equipment other than your FM receiver.

I performed the patch suggested by NuForce, it was very simple and consumed 10 minutes of my time.

Tvad, I do not have sheilded cable in my system, and I hear no sonic artifacts being generated by the NuForce amps when listening to digital sources. In fact, I have not heard or read a complaint from any users about RFI generated sonic artifacts.

Having completed the simple patch, neither am I experienceing any RF interference with my Audiolab 8000t tuner.

In my opinion, the sound of these amps is outstanding, and I personally am not ready to let this RFI issue turn my ears away from this product. Another thing that reasures me is that Jason at NuForce has publicly committed to offering users a solution to the RFI issue.

For those looking for low-cost, cool running, compact, high-performance amplifiers (and who isn't?), I am concluding that these amps represent an outrageous value.

We sent out parts and instructions to all dealers on May 25 & 26 for improving NuForce amp HF resolution and reduce RFI. Instructions can also be found on the updated support web page:
