NuForce Popping

Good to know. It's also possible that their source may have been causing this problem. I have a pop in my current system and I've narrowed it down to my DAC.

I have heard the Ref 9s and did like the sound and will most likely get a pair, hopefully soon.

Thanks.

Forgot to ask, how would I identify these older amps that failed a while ago? If I buy something from this site I would obviously want the updated versions.

Thanks for all your help. It's always useful to get the opinions first hand from those that own the products. You are right in that the store may have decided to not carry them as it may hurt sales of other products but I won't bother going there. There are some other other dealers in the area so I'll try them out. I was just curious on some of the things that I heard. I'm sure the amps are as very good and that NuForce are making changes to constantly improve an innovating product.
