“ REVIEW: Meier Audio Corda Classic solid state headphone amp. Introduction My first serious headphone amp was the Meier Audio Corda HA-2 Mk II. It was something of a revelation to me at the time – I had never heard a headphone amp that sounded as good. I didn’t have much experience with headphone amps back then, and the HA-2 mk II was a huge cut above anything...” --Skylab
“ Overture The Concerto, the newest amp from Meier Audio, is essentially equivalent to the top Meier, the Symphony, with a less features and a few tweaks. As such, it employs Meier’s Active Balanced Ground topology, and includes his famous Crossfeed image enhancer (which is supposed to be improved from the Symphony, and as always is defeatable), and a gain switch. That’s it for “features” –...” --Skylab
“I agree with pretty much everything the other reviews said, so I'll add how this compares to my Headroom Maxed Out Home (MOH). First, a little on the MOH I'm comparing with the Jazz. The MOH is a great amp: toroidal power supply, OPA627s biased class A, quiet background (high S/N ratio), linear, neutral sound. Power limited to about 250 mW and 250 mA which is plenty to drive just about...” --MRC001
“This review is based on matching the Mini X with Hifiman He-500 Headphones. You may be reading this review, unsure what to make of this Amp, asking how can a cheap sub $200 amp offer the power needed for an expensive Headphone such as the Hifiman He-500? If you have done your homework you will find this is the stereo amp everybody is...” --fluidz
“ REVIEW: Meier Audio Stepdance Jan Meier was kind enough to send me an early production sample of his new Meier Stepdance portable amp. The Stepdance is the first Meier Portable to use his “Balanced Ground” topology. It’s designed as a performance-first portable amp, which means it has very few features (for example, Meier’s normal Crossfeed is omitted), and it also uses...” --Skylab
“ ****Note**** As always, these are strictly my opinions. I try to present these products as honestly as possible and try to describe them as best as possible. As always, YMMV. ****NOTE**** FISCHER AUDIO MYSTIFY PORTABLE HEADPHONE AMP SPEC’S: Frequency “flatness”: +/- 0.5db Dynamic Range: 110 db Total Harmonic Distortion: 0.001% Intermodulation...” --LFF
“ This is a nice amp for its price! It really drives my GS1000i very good. Unfortunately I can not compare it with other amps and I can't remember how my other high-end amp sounded. Sometimes I regret that I didn't save a little more to buy the Corda Jazz amp which only costs like 100 euro more and which has the balanced option (without need to recable your phone to balanced). ” --alexdemaet
The QUICKSTEP is a technically very sophisticated portable amplifier. This amp was designed to provide the best possible portable sound with a minimum of compromises towards size and current consumption. The amp not only uses the concept of active balanced ground but also has a discrete volume control (32 positions, two gain settings). This volume control is not a standard industrial solution...
The PCSTEP is a portable amplifier that, in addition to its analog input, also has a built-in USB-DAC. When connected to the USB-port of your PC it will strongly improve on the sound that is provided by a standard quality soundcard. The amp has a discrete volume control (32 positions, two gain settings). This volume control is not a standard industrial solution but uses a concept in which the...
