Nuforce Primo 8 - an Audiophile Phase Coherent Quad Balanced Armature Driver IEM - Impressions - Page 11

post #151 of 289

I'm getting a second listen to the Primo 8; this time for a couple of weeks, so there's ample time. My thoughts are similar to what they were the first time around --- sound-wise, they're really quite good --- about as good as it gets for its form factor (small and single output port, not a CIEM-derived design), and definitely at the top of the heap for the <$500 category of universal IEMs.

 

I do believe I'm enjoying them a lot more this time around --- I'm not busy picking out its technical shortcomings within a 12 hour span!

 

Not to be a Negative Nancy, but getting the criticism out of the way first: the ear guides really are a bit too stiff. They feel nice against the skin, actually, but they take forever to adjust, and make the cable look thin comparatively. It's not a huge problem, but worth mentioning nonetheless.

I believe my first review sample was one of the earliest pre-production versions. I'm finding out that it'd been hand assembled and disassembled multiple times during development, as they made changes to the sound tubes and crossovers until the final version was settled on (remember, I was a beta tester with several versions).

So I'm wondering if other reviewers had similar pre-production versions, or if theirs were closer to the production-line version that I have now. That could explain some of the improvements I've heard with these, in addition to the improved tips and the polycarbonate shell.

I am so pleased with these, and I'm going to post my un-boxing photos tonight. The entire packaging is top notch. The only thing that I would change would be to go with a hardshell case instead of the soft case. It seems strange that I'm putting Nuforce IEM inside of the Westone hard case.

The packaging included a very nice box with magnetic closure, a microfiber clothe with NuForce logo on it, a quarter inch adapter, airline adapter, shirt clip to hold the cable, brush with wire wax scoop for cleaning them, soft case, two sets of Complys T100 tips, 8 medium/large silicone tips, and eight small silicone tips. I did not get three distinct silicone tip sizes, but the medium/large tips look like they will fit a large variety of ear sizes.

For people who want a more neutral sound out of the Primo 8, try using stem spacers and wide bore tips. I'm using the de-foamed core of the Shure Olives and using MEElec biflange tips.

 

The tips end up sticking beyond the normal stem about 2 mm, and with a diameter of 4 mm, creates a horn effect. Given that the original diameter of the stem is 2 mm, the high frequency gain is 20 log (4/2) = ~6 dB.

 

The overall effect is impressive; the top end is more revealing, and the overall tonal response is very good. This is not recommended for the kind of listener that wants a smooth, warm, organic sound out of the Primo 8; using wide-bore tips will bring out more recording artifacts, but will bring the FR closer to neutral.

 

For me, this is an ideal setup; the biflange tips help with isolation, and the horn effect gives me a sound response that I'm pretty satisfied with.

Just in case it wasn't clear of my post above, the Nuforce brand tips that came with the boxed version are using a larger bore at the exit and they do sound better than the Westone tips that I was using before.

Yep, they do have a taper to them, which is nice.

So I brought my Dragonfly 1.2 home from work to give the Primo8 another chance. The L-to-R balance problem seems to be a short n the cable.

 

They sound a little like the W4r but bigger pre-break-in and pretty damn good only 3 songs in.

Just ordered mine and NuForce was what got me starting in this audiophile journey with their ICON Mobile.  Can't wait to try it out.  Also Rin Choi has an excellent post on it's frequency analysis too.

 

p.s. I just wish NuForce include one more straight cable instead of only the MFI cable...

I know FIIO has a cheap MMX cable.

That one can't compare to the stock cable, besides I have some Moon Audio Silver Dragon V1 coming.  But that's besides the point, as at this price point they really should included two cables instead of just one.

The cable on these is already fairly expensive and high quality wire. I suggested that they offer two versions - one with one cable and one with two (mic and non-mic).

Heading into my second week of listening, I switched over to small-sized Shure "Olive" foams instead of sticking with the included medium-sized Comply foams. The sound has improved, leading me to believe that I need small-sized Comply foam if I am to ever get along with Comply without it sucking away treble response. My ear canals are too narrow otherwise.

 

My impressions of the Primo 8 have stabilized; I should be able to publish a review within the next few days before I have to return them.

(Hint: I think they're good and well worth consideration over the established guard of Shure, Westone, UE in premium universal IEMs)
