You should connect + and earth from the XLRs to + and - of the RCAs.  Leave the - connection from the XLRs floating.

cool works a treat!

interestingly enough it worked a treat the other way with an old amp

XLR to RCA – If you are converting the Preamp XLR output to NuForce RCA input (Reference , make sure that your XLR to RCA connector is wired correctly (even if you purchase off-the-shelf XLR->RCA connector, there is no guarantee that it is properly wired):

Pins on XLR are 1-ground, 2-hot, 3-cold (easy to remember), and when patch to RCA, it should be:
Pin-1 = RCA ground
Pin-2 = RCA center pin (+ve)
Pin 3 = no connect
Chassis pin = no connect

If the XLR adapter erroneously tied Pin 1 to chassis pin, there will be a ground loop, as Ref 8 chassis ground is wired to the ground on the AC cord = chassis ground on the preamp. But this is NOT EQUAL to the signal ground on Ref 8. It will basically short our RCA ground to our chassis (via a long loop through the preamp and preamp's AC cord, wall AC socket, and Ref 8 AC cord).

For other people who're using Ref 8b in their system, having truely balanced connections THROUGHOUT the whole system is important. Check with your equipment vendors (preamp, phono etc) about their balance connections.

It was only a matter of time before the modders got a hold of nuforce amps. It will be interesting to see what the level 2 mods can do.

Or prehaps Empirical Audio or some of the other amp modders can have a look at nuforce as well

[WerTicus]

i prefer to do my own mods or 'kit' mods.

Hi WerTicus, Well, I wonder if they will just imcorporate that maud in the amps you purchase? Now since I can't see the little graphs/pictures besides removing the caps, do you just bridge the spots where they were with wire and that's it?

i think you just cut it and leave it un connected.

What do the pictures show?

[WerTicus]

uhh well look and you shall see!

they are cut off completly.

Yes, you just remove the parts.  The mod is very simple and to me does very little sonically....especially compared to the other mods that I have done so far.  However, it certainly won't hurt to remove them.

I am selling the modded amps (level one mod is free) with the usual 30 day money back gaurantee and I handle the warrantee service in the warrantee period and any possible problem after the warrantee service period.  Level one mods make the amps sound better in just about every way: more palpable, more dense images, more 3D, more extended and pure highs, better dynamics, better imaging, tighter bass, etc.....basically more real sounding.

Hi Rick,

Read your site, so what Mods besides removing the caps do you do? You don't detail what is involved. What are the "Level 2" Mods, and any idea of charges? Thanks.

Ray

Mod info is proprietary.  What really matters is how it sounds....at least that is what matters to me.  There will be reviews of modded units versus stock units.  The pricing on the level 2 mods depends on what exact parts I use and how much time it takes to mod it.  I imagine at least $400.  But, it could be less, it could be more.  Level 2 mods available in about 4-6 weeks, maybe less.  Level 2 mods will be discounted for those buying the amps with mods installed.  Level one mods are free with the amps and $150 for anyone else.  I may raise the price of level one mods for others since I will now have to honor the warrantee myself once the mods are done....and/or, I may not do level one mods for anyone else, just level 2, since I would make more money and handling the warrantee would then make sense.  We shall see.

Hi Ric,
I need a new amp(s) and am considering either your ice powered stereo that you have on sale or the new nuforce amp with level 1 mod for free.  Which would be the better amp for my Sony SS M9ED reference level floorstanders?
Thanks,
Bill

[Ric Schultz]

If you cannot afford the better sounding Nuforce or REALLY need slightly more power than the Ice Power modules are fine.  The Nuforce amps reveal a whole nuther layer of reality than the Ice Power modules.  However, the Ice Power modules are very, very good and I used a modified version for my own reference amps for over a year.  It comes down to how fussy you are and how much you want to spend.  

The 100 watt Nuforce will be enough power for most systems but they do have their limitations.  If you play music at less than 100 db I would say the Nuforce will work fine.  If you want to seriously rock out or use the amps for home theater where you might be listening to 110 db+ peaks of monster stomps/explosions then wait for the 350 watter.

The support section on NuForce website is not intended for mod . We take a neutral position toward custom mod. Our policy is not to post mod. Any improvement will go into future products. Now, don't wait if you are going to buy a NuForce amp .  We'll obviously continue to improve the amp year after year, that's just the fact of life. The circuit board on the amp can be upgraded and we will announce upgrade plan with your dealers if it is available in the future. Don't expect any Ref 8 upgrade in 2005 as this amp is pretty good already.

Removing the two capacitors C44,C45 reduce RFI with FM receiver. All switching devices have some level of RFI. The side effect of that patch is that to some people it sounded better. To some, there is no difference. But it will not make it sound worst for sure.
If you can't see the picture on the webpage (why?), get it from

Just cut the two caps off. That's it. They're are redundant.

email support@nuforce.com if you have questions or problems. The more feedback we get, the more information we have to improve the amps. Don't be shy of emailing us things you like to improve, even though you love your current NuForce amp. I am sure after listening it for a while, you will eventually find something you wish it could be better.

Hum? Isn't RFI a form of distortion? I guess you have that in common with Tube Amps?

The circuit board on the amp can be upgraded and we will announce upgrade plan with your dealers if it is available in the future.

Will such an upgrade be customer installable?  Will you allow cross-shipping (or better yet, ship the upgrade board first and then allow the customer to return the original) so downtime is minimized?

Thanks!
