Energy RC-Mini’s + NuForce Icon and a little treat…
So after ‘Fringe it appears I’m not the only Rubyist with a deep love of music. I love music, listening to it, making it hmm not so much (I can’t) - thus thought I’d blog about further adventures in audio-listening-land. I needed some replacements for my desktop system after a minor technical glitch, and have been temporarily using some Def Tech Pro Monitor 800s with a NuForce Icon - see at end.
I’ve looked at Totem Mites, Def Tech Pro Cinema 1000’s, and been pouring over product reviews of everything under the sun, trying to find something in the sweet spot of sounding good, but not going to get strung up by..err.. yeah you can complete that one.
After an audition the Totems were honestly gorgeous, and sounded wonderful but just too expensive, and still quite big. Deciding losing my left nut wasn’t an option they were quickly ruled out. ProMonitor 1000’s were a step up from the 800’s but getting quite bulky for the desk and lost their appeal. Given that I don’t really like the 800’s for music they were off the list. Numerous product reviews and “my speaker choice is better than yours” leads you down a rabbit hole.
So Saturday I went to “go get the cat food” and ahem well we alll know what that means don’t we?, came back with a pair of these…

(note the bling gloss of the desk I made.. a year on it still looks hot)

So they’re Energy RC-Mini’s, I hadn’t seen many product reviews as they’re relatively new. However the Futureshop next to said pet food store had some in a listening room. Audiophiles will likely cringe with the slightest mention of going to FS, but well, tough!. One look and was all over them “ok, if they sound even half decent I’m getting them”. The sounded more than half decent, and while definitely not at Totem level, they also weren’t at Totem pricing.
Now, there’s something special about any toy that requires “100 hours of running in” (no shit). So it will be a few weeks before I really try to get them singing but at moderate listening levels they’re pretty hot. Teamed up with a powered sub and my work place has a whole new sound to it.
So what to drive them with ? Well I had previously reached out to the tubes and found this a few weeks ago….

Nestled between the speakers is a a NuForce Icon. This tiny little amp packs a little 12w punch which is MORE than enough to power any reasonably sensitive speaker in a desktop environment.
After reading many reviews I picked this up online (a $199 deal had something to do with that). I’m fence sitting. Honestly on one hand it has fantastic imaging, the DAC is brilliant, I’ve heard things I’ve never heard before. On the other the hiss. It’s a class D amp so by design it will hiss when no signal present. However I’ve also heard hiss during playback in quiet stretches - kinda weird but it’s like you need to get it warmed up playing reasonable volumes then the hiss disappears. I rma’d one board as it was all over the place and intrusive on songs. A second one and I’m still not entirely sold. BUT considering it’s also a DAC+Headphone amp it’s pretty much a no-brainer (compared to what you used to pay for decent sound cards) - note the Headphone amp circuit is dead clean so I’m assuming line out is as well. I’m going to look for some little valve amp or similar to put on the line out for it so I’ll treat it more like a preamp than a pure integrated amp. But for now she does the business.
To NuForce’s credit they are working to resolve my amp issue. It appears to be the speakers have some characteristics that means the amp ‘reacts’ with a higher noise level. They’re getting me an updated board to try out that should resolve it.
Updated 11th August It appears a lot of people are searching and hitting my blog for this little NuForce amp, I wasn’t expecting my post to feature quite so prominently in the search results. So here’s my impressions after probably a month with it ..
Noise issue aside (getting resolved shortly with a new amp board), which I’m assuming is only affecting a very low %age of icon owners. I am very happy with this little amp for the money involved. It’s an amplifier, headphone amplifier, and DAC (Digital audio converter) in one unit. For $249 it’s not a bad deal at all especially when you consider what some external USB solutions for DAC alone cost.
The DAC in it is way better than the Mac’s in built card. It’s picked up immediately via USB and just works. The headphone amp portion is great, through my Sennheisers it seems to make them pick up steam and really rock. Coupled with the Energy’s, again noise issue aside, it seems to have lots of headroom. In my 9ft sq office I have no volume troubles. My comfort level is below the amps output level (ie I’ll give up and not want to be in the room, before the amp runs out of oomph). The NuForce is now, I believe, released with some S1 speakers of NuForces’ own design. This sounds like it would make a great package for the ‘no hassle, I just want a good sounding desktop setup’. In my setup it kicks the pants off any ‘desktop setup in a box’ for obvious reasons.
The amp’s well thought out. Nice and small little unit (pictures don’t really do it justice about how small it is). Little things like a line out for an external sub are included. Basically plug it in, add some speakers, and a sub, and go. But beware. Audio equipment is a very slippery slope. There’s always the next upgrade down the line….. to go up from here you’re looking at tube amps, there’s a couple around for desktop usage, one of which I have my eye on! But you are looking a significant jump up in price tag. Or more traditional integrated amps which are way bulky and not really suited to a desktop environment.
If you want a small system for a den, cosy listening room, or desktop environment, highly recommended. Click here for NuForce Icon on Amazon.
Updated 26th August A number of amp boards later, some very helpful staff at NuForce, and suffice to say, the Icon (at this stage) won’t work well with Energy RC-Mini’s. So don’t buy my setup Something in the frequency response curve of these speakers really disagrees with this amp. I’m moving on to a different amp - using the NuForce as a preamp. I have a tasty little tube amp on it’s way up from the states at the moment, which should be quite something on the desktop. So if you’re contemplating different speakers other than the S1 for the Icon, I’d recommend posting on forums and seeing if anyone else has them. You may run a very small risk that they won’t work.
Now for the little treat…
So you get something out of reading this - people will pfaff on about audio gear forever. But it’s all about the music. So here’s one kiwi band that is truly amazing and tends to get rave reviews - if you’re into electronica and dub, try Pitch Black out for size - some free MP3’s from live performances, I recommend listening to the Tokyo mix http://www.pitchblack.co.nz/default.asp?s1=downloads. You can buy full mp3 downloads from here amplifier.co.nz (although for quality I obviously recommend CD Purchase)
Enjoy.

It must be fairly high end to power 12w for $200!
I sport a pair of old Yamaha NS-10M monitors with a 120w amp. I probably need a woofer to complete the set.
Pitch Black is nice. For something remotely similar, I also like Tosca a.k.a Richard Dorfmeister and also the William Caslon Experience.

Mr TopFunky - great meeting you at RF!
I’ll give Tosca/Caslon a try - thanks for the recommendations.
Yeah in amp land, all is not as it seems with power. I put very little faith in numbers. That little box can drive efficient speakers loud ! That said it’s not going to get people rocking out in a 20ft square room.. but my little 9ft square office does the trick.

Did you have luck fixing the noise that is high even while playing music (quiet piano music for example)?

NuForce are getting me an updated amp board that should fix the issue. Don’t let it stop you getting this amp unless you happen to have speakers like mine ! Check with NuForce first if you’re unsure. For what you pay for it the amp is amazing. I’ll post an update once I get the new amp board.

I just got the new motherboard for my Icon, unfortunately it has the same problem as the old one.
On JBL S38II and Klipsch RB-81 speakers the high frequency noise that exists while not playing music does not go away when I start listening something with quiet passages.
Any near field listening of music (speakers on the desk) is out of the question as the hiss overcomes the music.
It’s less noticeable when listening to a rock music that has almost no quiet passages…

Well it’s taken awhile but I’m now pretty happy with my setup. My Sophia Baby amp arrived yesterday. It’s sweet. ZERO noise (well not unless you put your ear right up to the tweeter, which is still being generated from the icon, same as with headphones into the icon) I’ve had a couple of “oh shit this isn’t working” moments, until I’ve realised no source signal has been played. I’ll reserve judgement on electronica played at high volumes for a few weeks until everything is bedded in, but anything else just sounds gorgeous. The current setup is Mac > USB > Icon > Headphone Out > Baby > Energy Mini’s + Mirage 8″ Sub . Kick ass home office sound system. The baby being a tube amp seems to take the harshness (ultimate clarity?) that the icon has out of the sound, which seems to make it less fatiguing to listen to for long periods of time.
Above all I’m pretty happy the background noise has vanished. Now it’s just source recording noise I hear, highlighting how bad some recordings are !
