Precursor: I've been dragging my heels on this review for months and months. Something something working 60-70hr weeks is not conducive to the hobby. So what I'm going to do is just copy and lay out snippets and pieces of what I've got, and hopefully you guys will ask me questions which will...

  This started off as just a review for the Celsus Sound SP-One active bookshelf speakers, but trying to describe any sound producing device in a vacuum is a fool's errand. I also obtained the SP-One because it is very similar in size to two other sets of bookshelf speakers I already had, so...

    This has been a bit of an odd review for me to write, because the character of this amp changes quite a bit with the tubes being used. So I will offer some bits and pieces, but then the rest is just going to devolve into a short tube diary.   Here's the webpage with information and...

Neurochrome HP-1       Full product info, specs, and measurements: http://www.neurochrome.com/hp-1-ultra-high-end-headphone-amp/     Introduction   So I've had on my desk these past couple weeks a lovely little amp built in Canada by a one-man show under the brand of Neurochrome...

Just copying this from another forum. Seems there are more and more of these Raspberry Pi options coming out. Really curious to see how NuPrime's take on it turns out if they decide to run with it. As someone who actually owns both the uDSD (small dac/amp) and IDA-8 (all-in-one power amp), this...

Sonic Unity / Encore mDSD         I was fortunate enough to have Encore send me a pre-production unit of their upcoming mDSD, a pocket-sized DAC/amp from the same pedigree designers who brought us the NuPrime uDSD which I also own. I have also owned all the iterations of the uDAC that...

        This here is another budget conscious IEM coming from the crowdfunding angle (MSRP $59, crowdfunding price $30). It's an interesting approach to bring out new limited release products that I think we will be seeing more of in the near future. The problem with designing any new...

    Announcement here: http://www.sonicunity.com/blogs/news-1/36252545-the-encore-rockmaster-headphone-coming-soon   indiegogo is now live: https://www.indiegogo.com/project/preview/e984f477#/story     I've had the opportunity to evaluate the Encore RockMaster OE before release. For the...

    Noontec is a name perhaps unfamiliar to most here in headfi. They are an Asian/Australian company that started up way back in 2002 making hard disk based movie/media players. This sort of product never really gained much traction in the North American market, as people here were more...

    To start, here are the features/specs from the website: http://nuprimeaudio.com/index.php/product/dac-headphone-amps/portable-dacs/udsd   For comparison/reference, here's my review of the NuForce uDAC-3 from only a year and half ago. My how time and technology flies eh...

One only has to go through my profile to notice that I've gone through a lot of Nuforce gear over the years. I never got into their high-end stuff, but I've owned or tried most of their budget and midrange setups. Since Nuforce has been bought out by Optoma recently though, their future remains...

I stumbled across this dac while randomly browsing audio stuff...       product page: http://www.essenceelectrostatic.com/product/hdmi-dac-blu-ray/   some reviews: http://www.soundandvision.com/content/essence-hdacc-dac-headphone-amplifier...

What is it?   A thing that makes the music louder Class A, single ended, BUT two units may be configured as monoblocks for balanced operation Constant-Current Output       So why monoblocks? Is it for the cool factor? The increased power? For the reduced crosstalk? The separate power...

So I got these in a trade and literally had them less than an hour before deciding I needed to make a balanced cable for them.   First up, I had to figure out the wiring. The plug that goes into the left cup is a 2.5mm TRRS. Hmm ok, that hopefully means it's a 4 wire cable already so I can...

Sitting at home with a wicked headcold, bored, and with a microphone...     (click to enlarge)   Singing the same note twice, but the top one is humming. It's interesting that the basic shape is the same but a bunch of higher order harmonics are missing.

  Some may accuse me of being a bit of a Nuforce fan, and to be fair I sort of am given the amount of their gear that I have owned and/or reviewed. I have enjoyed their products for many years, and their customer service has been excellent for me. That said, I don't give glowing reviews just...

    It's no secret that those seeking to amp the HiFiMAN HE-6 will veer towards speaker amps. However, it seems the more recent trends have been moving towards beastly current driven 100W monstrosities. That's cool, I've got no problems with that. I've played around with my fair share of...

So after a bit of prodding on the YKYAAW thread, this here is a thread to share stories about your worst dates. Also acceptable are crash & burns, pickup attempts, or maybe just some sad feels. Anyhow, let me start it off:             Wow that came out longer than I expected. ...

HAP-100   This is a companion review to my DAC-100 review here: http://www.head-fi.org/t/645068/review-nuforce-dac-100   Coming from the same stock, they share many of the same characteristics in terms of build quality and sound.   On the surface: - four selectable RCA inputs via...

They say idle hands are the devil's playthings...     Look what arrived the other day. Feature of note: variable bass vents! This should be interesting.      Why yes, I think I will...   blah blah blah, I didn't actually read any of it   hello my pretty, I will be...

So crazy transplant in progress...   The drivers: the venerable T50rp   the shell: V-Moda Crossfade LP - chosen because it looks cool, and because it has a series of bass vents in the cup as well as a baffle port, similar to the T50rp shell     Well ok, let's start with the...

Nuforce HP-800   Spec table from nuforce.com     Packaging   The box for these headphones is really quite pretty. And big. Slide off the outer box and you'll find... another box! Open that one up and you'll find your headphones inside tied down to a plasticky shell. Underneath...

edit: Wow I was sure rambling there wasn't I? Note to self, do not try to write when hopped up on codeine. So anyhow, the TL;DR version, this is how I originally allocated my headfi spending:    1:2:3 - which are the relative ratios of money spent on dac/amp/headphone   After expanding...

It seems I've been acquiring a lot of Nuforce gear lately. Well what can I say; I find a brand with good service and quality offerings, and I keep climbing up the chain. This review will be covering two high end devices in their “100” line: the DAC-100 and the HAP-100, a dac/headphone amp and a...

  As miniature 2.1 speaker systems go, for most of us it probably conjures up images of a small computer multimedia set. Yeah, not a good comparison right? I've gone through more than my fair share of speaker sets from the likes of Logitech, Altec Lansing, etc. You know the kind: two little...
