Hello I'm a newbie here, and learning a lot of thing about class D amplifier these days reading forums. Once I have heard that NCDV S2 power amp was as good as Hypex NC400. But there was no information about it in this forum, that's why I started this thread. It is of course class D amp, but...

We've all heard it: Yamaha is spacious and likes its bass Marantz is warm and colored Onkyo is dark and shimmering (whatever...) Audiolab is neutral and cold Cambridge is midrange-centric Etc... Where do these ideas come from? Is there any psychoacoustic or another basis for them? Maybe in...

What does bypassing tone and loudness controls do exactly to enhance an amplifier's sound quality? Can anyone actually hear the difference? (I can't) If anyone can hear the difference, what does this difference consist of?

When I first saw schematics of vintage Kenwood KA-5010 amplifier, 2 years ago, I was immediately attracted and decided to build a circuit copy, better say a copy of the circuit topology with some newer solid state parts used. There were 2 points leading me to this decision - frequency...

Hi All, I didn't see too many reviews on this yet so I thought to ask, has anyone here purchased/listened to the ifi Zen Dac yet? I recently purchased the ifi Zen Dac for home use with my desktop machine, and am not really sure what to make of it. For anyone wondering, this thing here...

Looking for advice on a 3 channel Hypex Ncore amplifier - ATI vs Nord/Apollon I currently have a ATI AT528NC amplifier which powers my surrounds and atmos speakers. I am looking for another amp for my LCR (Procella P8). I have decided to stay with a Class D amp specifically Hypex ncore based...

Due to overwhelming ASR member demand (kidding) I thought it would be interesting to compare three high-performing DAC/amp combos: the Sabaj D5 vs. the SMSL M500 vs. the Topping DX7 Pro. Thanks to @amirm for all of the measurements; all of this info is from him (unless otherwise noted), I'm...

I just saw this old video and I just think it's wrong on so many levels. If this is a marketing video, it's very bad. NO ESD grounding, opening it on the carpet and not the right soldering tip. Also, what if I want the ORIGINAL sound? Not to mention all these will MEASURE differently. And...

hi-finews.com has run a performance analysis on the NAD M10 streaming, integrated amplifier recently, and this is what they found - I can't attest to the validity of it , though...

Hi all, So the challenge is this. I want to keep sound coming from my DAC (LG G5 smartphone) which I like alot, except it does not do bass well (I am aware of equalizers, but they don't do the job well). Is there a hardware combo for portable use that will let you keep the DACs sound but...

Hey guys, this is actually my first post on this forum so maybe a little introduction is in place. I am an electrical engineer from Finland and I've been in the headphone audio scene for quite some time now, went through a lot of gear and decided to do some measurements of my own.
