Review 1 of 2

Price Paid:  $120.00 from quain radio, argenti

Summary:
I purchased this to replace my broken Sennheiser HD-330 (expression line). I was looking for a country of manufacture in Europa or Japan, trying to avoid chinese procedence. My HD-330 was made in Ireland, and IMHO the quality was excellent, and the sound was very clear and without coloration. Perhaps today this means nothing (chinese facility could operate with european trasducers and so on) but, well, it was one of my search constraints.
So, when I saw this K-100 made in Austria, I thougt "I cannot go wrong'. I already purchased an AKG K-55 last week, but I found this model more focused on mass market of consumer electronics, MP3 and other compressed media reproduction, with lot of coloration in the bass and treble section. However, the K-55 performed quite well for a PC system.
On the other hand, this K-100 looks great (the K-55 has a cheap appeareance), the leather headband is a nice detail, and the silver-inked AKG logo printed on this band adds elegance to the set. Because it's a closed - semiopen model, perhaps the ergonomics could be a little bit enhanced, (the earpads doesn't surround competely your ear unless you have a small one), and the first impression I had is that these ones are not as comfortable as the Sennheiser.
I tested these ones with Pink Floyd's "Dark side of the moon", perhaps the most outstanding rock-n-roll recording work of all time, a remastered version, hybrid SACD edition. Unfortunately, I haven't a SACD player (so far), so I had to play the regular CD layer. Using a Yamaha RXV-557 and its digital-optical entry, letting the PCM converter at the Yammy do the work (I set the digital output at the DVD-player as 'raw bitstream'), and setting the tone control as flat (defeated), I could compare this AKG K-100 with the K-55 and the Sennheiser.
And I have to admit the K-100 has a flat response curve, like the sennheiser. In fact, they sounded similarly, with great respect to the recorded material. Excelling in medium tones, the voices were very well reproduced. IMHO, the K-100 compares very well to the HD-330, and this is all an accomplishment. Please don't get my wrong, these ones are not full-fledged audiophile-grade phones, but I think it behaves like one.
The K-55 showed a noticeable bass and treble reinforcements. Anyway, in Pink Floyd's first track, the hearthbeat effect yielded an incredible bass beat without distortion. I think the K-55 easily adds 2 or more decibels, acting like a "contour" or "loudness" control. The K-100, OTOH, outputs a flat, realistic, sound, perhaps well suited to act as a monitor headphone. High tones are soft , bass is detailed, chorus voices and stage image are very good (you can "locate" inside your head the different voices singing).
For the audiophile enthusiast, AKG added a pair of plastic pieces, intended to be located onto the drivers, by removing the earpads. These ones act like a mechanical filter for high frequencies. AKG states that some digital sources could output more level in high frequencies than the real, recorded sound, thus adding an artificial "brilliance" to the music. These plastic pieces tend to restore the equilibrium on the high frequency side of the spectrum. I didn't tested it because in fact I found the treble sound very equilibrated and with enough accuracy.

Strengths:
Nice design, leather detail adds elegance. AKG logo and "made in austria" inprints remarks the audiophile inheritance of these ones. Detailed sound, almost flat, without noticeable coloration, these ones can be used as a monitor pair of headphones.

Weaknesses:
None so far (considering the price).

Review 2 of 2

Price Paid:  $100.00 from Ostanek's Music

Summary:
I got these headphones as a result of my Senheiser's wiring shorting out after only 2 days of use. They didn' have another pair of Sennies around so the sales guy suggested that I try the K-100s. I wasn't dissapointed! They offer a different perspective than regular cans, mainly more of a loudspeaker perspective on the sound rather than a over-anylitical sound. I have used these cans to monitor my playing in the studio (although, do not use them close to a microphone for vocal work- they will bleed like crazy and even feedback if you get the earpeices too close to the mike!). Sound is very full and rich- very audiophile friendly while retaining a lack of hardness (even on my computer CD rom's 'phone outs!).

Strengths:
Very warm sound and can be driven by just about anything to decent levels. Headband is VERY comfortable.

Weaknesses:
These are NOT for studio use in front of the microphone! Like I said, they will bleed like crazy if you have the level too hot (and who doesn't when tracking vocals or acoustic guitar?).

Moscode 402Au OLT stereo power amplifier Review

George is adamant about the fact that the Moscode 402Au is not just a tube gain stage slapped onto a solid-state power amplifier; rather, it is a tube amplifier with a MOSFET output stage.

Lowther’s DX-65 driver in the Teresonic Magus XR Review

A new driver from Lowther is real news. A new five inch driver is even rarer news, so it was with great anticipation that I waited on this pair of speakers to arrive.

Aune Mini Headphone DAC User Review

The unit arrived from China well packed and everything seem to be in place. No external abuse by the carriers. The only problem was the power supply it came with. The box came with a cheap step-down converter.
