**Note: NOT an April Fool's Announcement**   I'm a big fan of Custom Art. I have both the Music One and the Music Two silicone CIEMs. To me, they represent some of the most well-rounded silicone CIEM products on the market. The company itself, begun by fellow head-fier @piotrus-g in Warsaw...

DUNU DN-2000J, shot on Canon EOS 6D with EF 100mm f/2.8L Macro IS USM Single gridded reflector shooting into medium-sized white foam core overhead, with white reflector fill cards.   Introduction   Over the past few months, I've had the opportunity of having renewed contact with...

Celsus Sound Companion One   This is an exciting product --- I've been testing out this portable DAC all-in-one for the past few weeks, and it's pretty darn cool, with all the bells and whistles a portable DAC can possibly have. The digital heart is an ES9018K2M found in many portable devices...

In recent months, as part of FiiO's internal testing programme, I've been privileged to test out revisions to FiiO's well-received E10 and E11 products, the E10K and E11K, respectively.   The E10K and E11K, despite being named 'K' revisions of the original models and thus might connote minor...

UPDATE, 2014-10-30   Looks like they've come live with a nicely polished website: http://www.marvalveaudio.com/index.php   Some design features it claims:   Innovative circuit design No-feedback circuit design for pure sound and better transient response.   Sounds pretty good to...

Today, I managed the privilege of listening to some demos of CIEMs from a company on the eastern coast of Italy, largely unknown to the head-fi community, called Livezoner41.   I first heard about this company from the Japanese, who are incredibly adept at finding new and unique CIEM...

INTRODUCTION   TBH, I haven't been the biggest fan of Astrotec --- they always seemed to have great potential, but again always seemed to deliver just short of that promise.   I've also not been a great fan of hybrid dynamic/BA IEMs. However, ever since the AKG K3003 released in 2011, it has...

This post is a review of the CustomArt Music One single-driver, silicone-molded CIEM. Piotr Granicki (aka piotrus-g), proprietor of CustomArt, originally sent me the Pro 100 for review (see the second post of the thread). Recently, because of canal fit issues, I had the Pro100 model remolded...

CustomArt Copper Two   I don’t know much about Poland; the only things I knew were antiquated truisms --- that it was the gateway to the eastern bloc and that it had a relative abundance of kielbasa. Other than that, I was pretty much clueless. However, ever since joining head-fi, I found out...

Portable Amplifiers from the Far East...     I would like, firstly, to declare that my experience with portable amplifiers has been limited. I’ve heard my fair share of them, but have never made them a priority, primarily because I didn’t like carrying them around, regardless of how...

Suyama FitEar, Japan's foremost custom IEM maker, has come out with a universal fit version of their flagship monitor, the MH334. As denoted by FitEar's naming scheme, it's a three-way, three-receiver, four-driver earpiece, denoted to be 'Mastering Grade' as it was tuned by recording engineer...

REVIEW | TDK TH-ECBA200BBK     For those into photography, all my photos are taken with an ancient (by digital camera standards) c. 2006 Canon PowerShot S3 IS. It only has a 1/2.4” CCD sensor and has an 36-432mm (35mm equivalent) lens, so dynamic range isn’t great and high contrast edges...

A while ago, I received the Hisound AMP3-M, along with a few of their earbuds (Living, PAA-1 Pro, etc.). I finally got around to taking care of this review, only recently.     Design & Function The AMP3-M is a small and simple DAP. Approximately the size of two third generation iPod...

This is the Appreciation Thread for the TDK BA200. Although formerly plagued by poor distribution and marketing outside of Asia, the BA200 is steadily becoming recognized as a remarkably mature-sounding, high-fidelity offering from recording media veteran TDK, with a smooth but revealing...

It looks like FAD, known for incredibly pricey universal IEMs, is coming out with a budget friendly line, called 'Adagio'.   They look to be based around an 8mm dynamic driver, and the three models confirmed so far are the Adagio II, II, and V, priced at 3980¥ (~$51), 5980¥ (~$77), and...

I was just randomly browsing the FAD website when I noticed that they recently introduced a new 'Heaven C' model... a simple Head-Fi search didn't yield any results; does anyone have any information regarding it, especially compared to the SS, SB, and A1?   My non-existent Japanese language...

Hisound Audio is a Chinese audio manufacturer with aspirations of being a leader in the enthusiast/audiophile segment of portable audio. Its products are no stranger to Head-Fi, namely their media players --- the AMP3 and the Studio variants. However, Hisound as a company is still an unknown...

My friend has a pair of ADDIEMs and he says that the cables are yellowing, and thus wants to get them cleaned. I told him that maybe acetone would work, but I've never actually tried cleaning cables before. Has anyone tried cleaning yellowing cables before?

Two IEMs have arisen on Head-Fi lately as products that offer top-tier sound quality for mid-fi money --- they’ve received very high marks from several veteran reviewers and have gone on to become hot topics of discussion, including the age old question of “Which should I buy?” This comparison...

Hifiman has long been a darling of Head-Fi and while I've read much about its various products, I've never had an opportunity to listen to any of them. I'd pretty much decided that the next time I return to the States, I'd order a pair, but I can't seem to set myself down for a pair that would...

My laptop's music library is quickly filling with hi-res music, so I'm looking for a decent, budget (<$250) DAC that can receive a 24/96 signal over USB.   Currently, I mostly use the Fischer Audio DBA-02 and Superlux HD668B, neither of which require much amping, if at all, but are both...
