    First impressions after first dip into class D (2x Hypex Nilai 500 Mono)

    I had a bit of an experience in ordering and getting these amp kits assembled and working. The amp modules themselves seemed to have been damaged in shipping (vibration caused several caps legs to fatigue via vibration and break off). Hypex (and my retailer, Deer Creek) did a great job taking...

    Question about class D

    So, I got a new class D amp (TPA3255) to replace my old AB amp, all in all I think it sounds much better than the AB amp, but I have one big gripe with it. I noticed this without listening for it, compared to the AB amp it makes music faster, like there is no space between one note and the...

    Is the SMSL AO200 a true "Digital Amplifier"? (or do the analog inputs bypass its built in dac?)

    I'm wondering if the analog inputs on the AO200 bypass its built in dac? All of the marketing material for the AO200 calls the unit a "Digital Amplifier," but that would imply that every signal going through the amp is converted to digital before amplification, is there a way to test if the...

    Class D vs tube at the listening position

    After recently purchasing a New (Very Old) Stock Audio Research amp from a store and noting how I subjectively liked it in comparison with my existing amp (March Audio P502 Hypex), I thought I would take some comparative measurements at the listening position to look for any differences...

    Octavio AMP

    Hello, I'm curious about this product. There are no reviews. Octavio is like a French copycat of Bluesound. They made a first splash with their Octavio Stream (200€), a streaming DAC with only one AUX input and no digital outputs. Octavio uses Octavio Virtuose for streaming. It looks...

    ICEpower 2000AS2 HV

    New module announced by ICEpower, with integrated buffer and SMPS for 588 usd. 2 x 1000W or 1 x 2000W, 5W SINAD 98 excellent (4 ohms, 1% THD+N). Still not tamed the highs though like Hypex NCore(x) and Purifi Eigentakt did.

    Class D A07 x class D UcD180 and class AB amp - there are measurable differences on acoustical side

    Following the assumptions on possible influence of ultrasonic noise and carrier frequency residuals to tweeter output I have prepared an experiment where the tweeter is driven by 2.82V sine tone of 6kHz from 2 different amplifiers. One of the is AIYIMA A07, see my review...

    Wacky AGD class D with GanFETs in a tube

    Hifi News has a review of this very expensive class D with some measurements. Seems to use an Infineon Merus driver with the GanFETs output switchers in a tube bottle. Good power but doesn't seem state of the art in measurements, but interesting with slow rise in distortion with both power...
