Does Anyone have any experience with Nuforce Amps?

Let me know when the Nuforce arrives, I'm there! I can bring a 150w(?) UcD for comparison

That is a comparison I would like to hear about considering how highly the UcD modules are talked about by the DIY audio people.

That's more of an issue for their dealers, not the manufacturer.

Hi Agisthos...

NB hopes to have it sometime this coming week, so perhaps we'll get together next weekend or the following.

"I have heard that VAC make some of the best tubed gear around and that a lot of solid state heads would even like their stuff"

I've a bottom of their line VAC Avatar which, being an integrated with no pre out/amp-in, is rather apples and oranges. In the past I've compared it to an AKSA 100N+ and a Butler 2250 and, although exquisite, at 28w it just can't always control bass like the bigger boys can, at least not with my 86dB Scan Speaks...

tvad4, it was good to hear your thoughts on with the original Ref 8s (70wpc and 21 dB gain) I loaned you. I believe that you would have had additional gains in sound quality, perhaps enough more to please you fully, if you had used upgraded power cords instead of the stock cords. So I correct this soon by stocking some loaner upgraded power cords for future NuForce amp loans.
Very Happy

Thanks,

Bill

Every audiophile, even the hard-to-the-core addict, sometimes just wishes for a no-tweak, no-sweat system that just works and sounds great.

In a few years, I imagine my system will have moved to a more refined version of one of these switching amplifiers, maybe with latest-greatest DAC installed internally, maybe even with USB 2.0 input. I'll just hook up my computer up to it with USB, use some decent zip cords to simple speakers and be done.

With what seems to be a tidal wave of these economical d ...

Lucid, cogent, & right on the money. We are in an amazing time audio equipment-wise.

Ref series is going to continue for a long time and it is our high performance reference series. We have learned that some editors are going to use them as reference amp to review other equipment such as speakers etc.

We don't have a time frame :) for the other series yet. Just like cars, different products cater to different buyers.

But we'll like to hear your opinion. What do you want and how much are you willing to pay ? A jewel case for double the price :)

1 K for each with the fancy case, total $2000. Unless that case is gonna wash my dishes and do my laundry, then asking double your present price is pure vanity. I could see if the price went up a third if the parts inside were even better than what you are using now. You would be doing more pioneering work if you made the PC board using Silver instead of copper. Now that would be an interesting project, with good sonics behind it.

Hey NuForce,
looking at the size of this thread and all of the interest generated in NuForce, I think you should offer Rocket some kind of gesture of appreciation for starting this thread.

I know, NuForce has become the most viewed/discussed thread of the entire website. But we'll have to thank him privately though

Actually, you have quite a ways to go for that, but with 2 more posts you'll have Chuck Josephson beat...

Congrats though!!!

Maybe, they need to give him a Nuforce pen. lol.

There are several technical aspects of NuForce amp that contributed to the performance (our CTO Tranh might have to help out if I got into trouble here) and no other amps have the combination:
1. Very high damping factor - therefore the ability to drive any speaker and super fast response. We have measured the output (source) impedance and it is near zero (10 milliohm) for the entire frequency response. No other amps come close. Therefore the damping factor is extremely high. It is very difficult to have low source impedance at high freq.
2. High bandwidth - we think this provide the wide sound stage
3. Low distortion - this is very hard to measure with equipment due to the carrier frequency that is being treated as noise. But overall THD+N is very low.
4. Phase shift - almost no phase shift. Most amp has 180 or more of phase shift
Some other amps can do one or two of the above, but I will be interested to know if there's any amplifier out there that can meet all four criteria.

May be we should take this discussion elsewhere as we want to leave this thread for listening aspect of NuForce amp.

my review is also at the above link, three posts down

WerTicus · « **Reply #216 on:** 1 May 2005, 10:06 am »

whats the difference between the balanced version and the normal version? is the difference worth the persuing if one has balanced output on their source?

im not really familiar with the difference between the two connections at all - or in regards to nuforces implementation.

nuforce · « **Reply #217 on:** 1 May 2005, 10:31 pm »

Ref 8b has a true balanced XLR input and better looking faceplate (labels are machine milled).
If you have balanced source, you might want to consider paying extra to get Ref 8b. Internally, they use EXACTLY the same circuit board, which is designed for both balanced and unbalanced input.
We have a few editorial reviews comparing XLR and RCA coming out in June.
It cost more to include both inputs (larger chassis, more connectors) and not everyone want to pay for the extra features

.

WerTicus · « **Reply #218 on:** 2 May 2005, 05:12 am »

I have just ordered the balanced version through my dealer.

Now the question is - with regards to balanced input, would the nuforces sound better with a longer run of interconnect or a longer run of speaker cable?

Because i could have either length very very short and the other length would need to be a couple of meters.

nuforce · « **Reply #219 on:** 3 May 2005, 08:12 am »

The input impedance of NuForce Ref 8 is 47Kohm (other amps also have high input impedance). And your speaker impedance could range from 2 to 16 ohm (at various freq).

Comparatively, the impedance of your speaker cable is a significant part of your load impedance. Therefore a shorter speaker cable should be better (advantage of a 2.5 lbs amp hidng behind the speaker)
