Reviews from around the world
Reference Series: 8.5, 9, 9SE

Reference Series V2: 8.5, 9, 9SE

Robert H. Levi & John Brazier, Positive Feedback Online, USA
"I can't name a solid-state amp that gives you soundstaging, imaging, or depth perspective better than these little guys at under $8000! Moreover, at this kind of high power. What a deal! The Reference 9V2s are the best yet from NuForce and receive my highest recommendation" ---> Reference 9 V2 Full Review (download PDF copy)

"The Reference 9 V2 is a great amp by any measure (and I’ll bet it measures like a dream)... However, as impressed as I am by the Ref 9 V2, I’m in love with the Ref 9 SE V2. I don’t see how amplification can get much better than this. Different, certainly, which is why so much zealous partisanship informs perfectionist audio. If you’ve a hi-rez system and value verisimilitude, the Reference 9 SE V2 belongs on your short list." ---> Reference 9 V2 and 9 V2 SE Full Review (download PDF copy)

Reference Series V1: 8.5, 9, 9SE

These acclaimed reviews are still relevant after the introduction of Version2 technology. They provided a window into the history of Nuforce product development and its platform strategy of offering customers continuous upgrade path.

Chris Martens, AVGuide & The Absolute Sound, USA
"Because NuForce's Reference 9 monoblocks are eminently affordable, you might think they won this award on the basis of value, but that's not the half of it.  These little Class D gems are sonic shockers in ways normally associated with amps that cost a fortune.  Their defining characteristics are terrific transparency, incisive dynamics, deeply extended bass that offers excellent pitch definition and "traction," and superb three-dimensionality.  Though accurate almost to a fault and lacking the luminous midrange glow of some of the greatest tube amps, the Reference 9s are charmers in their own right, with an uncanny ability to reveal previously hidden information in familiar recordings." (Reviewed by Chris Martens, Issue 158.  Power Amp of The Year, Issue 160)"

Edgar Kramer, 6moons.com, USA
"In comparison to other amplifiers, I would have to say that the Reference 9 Special Edition monos are amongst the best all-rounders I've come across at any price. ...
Over the last two decades, professionally and as a 'true blue' audiophile, I've owned/auditioned/assessed/compared scores of excellent amplifiers using all manner of technology and circuitry. I consider the NuForce Reference 9 Special Edition amplifiers to be amongst a select small group of the very best amplifiers I've heard. In fact, the SEs better most of these elitists in the areas of resolution, dynamics, bass power and frequency-wide detail."

"...So, no Second Coming or Rewriting The Rules yet when judged from the jaded ivory tower seat; but a major thumbs-up from the real world where everyone else cavorts and frolicks."---> Reference 9 Full Review

Jeff Van Dyne, Home Theater and Sound, USA
"NuForce has advanced technology for the sake of art and has done so with tremendous success. If you’ve been hearing a lot about this amplifier and have wondered whether it’s everything it’s cracked up to be, it is. The NuForce Reference 8.5 monoblock is the best-performing amplifier I’ve ever had in my system, and no one needs an engineering degree to understand that." ---> Reference 8.5 Full Review (download PDF copy)

Robert H. Levi & Ed Morawski, Positive Feedback Online, USA
"...the NuForce 9.02 monoblocks are now the most deliciously musical solid-state amplifiers I've heard. As I listen, I just want to hear more, more, more, and any bit of fatigue has been zapped. To the slippery-smooth sound, extraordinary detail, and wondrous dynamics of the 9.0s, the 9.02s add textural cues and liquidity..."(Robert)
"...It is quite astonishing how much bass these little amps produce—I never got completely used to it. I was quite pleased with the Reference 9s. Not only do they represent very good value for the money, but they also offer convenience, power, quality, but most importantly, extremely good sound." (Ed)

"The definition of the 9 SEs is as good as that of any solid-state amplifier I've heard, and that includes Halcro, Pass, Edge, etc...

"Of all the accolades these amps have garnered on the 'net and in print there is one statement that nearly all the reviews have included as the icing on the cake, and I too am compelled to join in that song….

"...I consider the Reference 8b a standard-setter equal to the Mark Levinson ML2 of the 1970s or the Bel Canto eVo2 of the 1990s..." ---> Full Review (download PDF copy)
(NuForce note: Jim followed the unveiling of NuForce's amplifier at CES 2005 and has gone through a torturous process of listening to several Reference 8 versions while we continue to enhance the amplifier and that reflects the first part of the review. Thanks! The review eventually focused on Reference 8b. Reference 8 has since been updated to exactly the same circuit board as Reference 8b.  And both Reference 8 and 8b have received further upgrade since the review.)

Frank Alles, StereoTimes.com, USA
"...My feeling with the 9.02 was that its speed, bass control, treble extension, and overall focus had likewise improved over earlier versions..."

Mike Silverton, UltraAudio.com (SoundStage! Netowork), USA
"Consider a pair of tiny amps that, as I hear them, exceed the sonic performance of a humongous and rightly celebrated twosome that cost a tad less than six times as much. I have seen -- and heard -- the future, and it is indeed a hoot."

Lucio Cadeddu, TNT-Audio, Italy (in English)
"The NuForce REF9's are the most evident proof that Class D technology is mature and can perform extremely well, so much to be able to replace "traditional" technology in terms of quality/price ratio, to say the least...I'm quite sure die-hard traditionalists won't accept this sign of the times. I'm not optimist. Still, I hope clever audiophiles will - at least - try to understand WHY this technology and these amplifiers in particular are a true revolution, the first one in decades of solid-state technology. It is NOT an easy step, I do understand, it hasn't been easy for me, either. The NuForce REF9's represent a modern era Rubicon." ---> Reference 9 Full Review (download PDF copy)

José Victor Henriques, www.hificlube.net, Portugal
"Positive Feedback, Soundstage, 6moons, StereoTimes, UltraAudio; The Absolute Sound, Hifi World, Haute Fidelité et al, from Holland, Sweden, South Africa, surrendered unconditionally to the Nuforce Revolution. Just by reading quotes or full reviews in the best international audiophile magazines, the reader might think this is a press conspiracy against conservatism reigning in the audiophile kingdom with the alleged aim of leading Nuforce to power. Hificlube listened to a Nuforce public speech - and willingly joined the revolution…"

Deon Schoeman (Chief Editor), Audio Video South Africa
"It’s very hard to equate such a performance to both the physical dimensions of the monoblocks, and their asking price. Both delicate and powerful, equally intimate and expansive, with a real empathy for the music, the NuForce Reference 9s are the power amp arena’s ULTIMATE GIANT KILLERS!"

Ruud Jonker, Music & Emotions, The Netherlands
Switching amps are getting better ervery time. Nuforce sets the standards both in sound and in pricing. Nuforce is far better than the big majority of traditional Class-A or Class-B products. Every audiophile should listen to it once to draw some (painful) interesting conclusions in comparison to their own set. --->

Reference 8

Reference 8 has been discontinued but still supported with V2 technology upgrade and trade-in, a demonstration of Nuforce successful platform strategy.

"...We warmly recommend the Nuforce Reference 8, listen to them and be amazed and surprised. With the latest upgrade, we just have to purchase the reviewed amplifiers. At the moment it is our new reference power amplifier" (extracted from conclusion section and translated to English) ---> Reference 8 Full Review (download PDF copy)

"...The NuForce amplifiers have stolen my heart. They will no longer leave my house. I will use them as my reference amplifier from now on. Every amplifier which I will listen to in the future must be compared to NuForce." ---> Full Review (download PDF copy)
