Nuforce

Jason, thanks for your response. I already have a Panamax
5300. How will that work for me? In the next week or two these amps will be put to the test against Levinson 33's driving Grand Utopia BE's. Even if they are close and can drive these speakers especially in the low end then they probably will be regarded as a giant killer. I believe the ref 9 with the extended bass will be used without any internal mods.
Do you have any recomendations for vibration control for Nuforce amps? I am using black diamond racing pucks and cones for my cdp and they work great!

Jp1208,

I'm getting excellent results with my Reference 9s using a PS Audio UPC-200 AC line conditioner. I think it's always best to use some form of AC line filtering when possible.

As for using pucks, cones, and such, I've experimented briefly with some of those things, but I'm presently getting great results with the Ref 9s standing on their own feet on a couple of corian planks set on my carpet.

I've recently had a sonic breakthrough using the Benchmark DAC-1 via its fixed outputs through a buffered, unity-gain solid-state linestage and then into the Reference 9s.

To my ears, using the Benchmark's variable outputs directly into the amps produced a very detailed and intimate sound, but one that was on the bright and thin side of reality.

Then, rerouting the Benchmark, using its fixed outputs through my buffered linestage and then into the amps literally transformed the system. The soundstage dimensionality literally took command of the room and all of a sudden there was a richness to the lower midrange and bass that just wasn't there before. I am amazed at the transformation. I believe this is the best sound I've heard from any system at any time. It is most certainly the best sound I've ever experienced in my current listening room by a considerable margin. Obviously, the system could not sound this fantastic if the Reference 9s were not doing their part.

I'll be curious to hear your impressions of the Reference 9s in your system once you have a chance to play with them and do some listening. They will definitely show you what the rest of your gear is doing or not doing and you'll be well rewarded for each compatible system change you try.

Unless there was a particular problem with this pair of amps, the sound of this system was not very pleasant noted by all including the dealer . The Nuforce line in this case was not added. I was disappointed as a customer that it did not sound the way I had read that it should.

It is hard to comment without knowing how much breakin the dealer has allowed for the amp and whether anyone has attempted to re-configure the system or adjust for speakers toe-in position (toeing out). If you read many of the reviews (from professional reviewers to serious audiophiles) from magazines to online forums, they have taken the trouble to tune their systems. NuForce is ruthlessly revealing amount many other things. In addition, NuForce is a very neutral amp and it present the recording as it is. You don't find people describing it as warmth or sweet (to me that's distorted sound but hey, there is no right or wrong, music is very personal). So by introducing a neutral amp into a system that has been very well compensated can suddently appear off balance.

There is only one way to know for sure how good
the nuforce amps sound, "I Kid You Not", Listen
To Me. All Amp generate Noise! Resonences, they
Vibrate, Hum, and so on, One only needs to place
8s or 9s on Maple Block just big enough to hold
them, possiblly weigh them down with about five
LBs of lead shot spread evenly accross entire
top of amp. Now in equal triangle set Stillpoints
with height ajusters under Maple Block, scewing
the Stillpoints up and down, while listing you
will be able to effectively drain off all Noise
from chassis and Amp, "Stillpoints Can Do This"
You will here your Amps for the First time with
out noise being added into swicthing ICs, this is
critical because of the shear speed of the ICs
can "smear" or distort any noise thats innerduced
in to them. All equipment that us audiophiles use
generates noise, there isn't one that can't be
Vastly improved by direct ajustable hight Still-
points, Try it, You'll "Freak Out!" and become a
Believer like me.

What does Nuforce have planned for the immedeate future. I'm looking for 500 watts into 4 Ohms.
