Class D amp with Tube Preamp Combo?

Hi Kenk168, I have never experienced noise with the excellent Nuforce Ref 9SE V2. under what circumstances may such noise show up and become a problem?

I have never had a noise issue with my V2 SE's either. I will agree that power conditioning and lots of break in really make big differences with these amps.

Hi Guidocorona, Jim and anyone interested,

Here's the review Ait did some time ago where he referenced the Nuforce Ref 9V2SE with others:

I believe this is an aberation, perhaps limited to his set up, and not a typical scenario for the Nuforce.

Thanks Kenobi, now I do remember the review. I can only guess that AIT may have been dealing with a NuForce right out of the factory or with very incomplete break in, or dead cold. Only on a dead cold and recently installed NuForce I have experienced noticeable artifacts at the top. These went away gradually with time. . . and completely.

Hi Guidocorona,

Thank you for your confirmation. It took me a while, at least a few weeks for the sound to mature and probably a few months to where its at currently.

Audiophiles are an impulsive bunch and not the most patient. I am also one. Luckily, this time, I stuck around and am being rewarded. Many who did not have successful integration with their systems didn't give it the proper time and a bit of care in priming the unit to the rest of their system. In my case, I didn't discover its magic until I got rid of hard spiky cones and other detailed-wrenching isolation bases (and replaced with softer, more balanced ones) from the rest of my components. Turned out the NuForce amp itself had that in spades and needed no help in that area. A bit of warmth from cabling or upstream sources will nicely balance its inherent attributes and allow it to play music the way its intended.

Best regards,

Kenobi
