Question for Amp Designers
I've heard it with my own amps. I have 3 systems in my house and for some strange reason I Iike to swap out pieces to hear the changes.  
Class D Technology
Well nothing’s perfect but in all honesty gotta say that Class D done well comes about as close in all ways that matter as anything I’ve experienced in home/high end audio. Even without breaking the bank in some cases. If I were competing with ... 
Using Pre-out / Main-in with External Crossover
Thanks George. What about this comment that I read on an old thread.  BTW pre-out main-in is not a good place to hook up an EQ from a S/N perspective. The amplifier applies constant gain to any signal at the main-in connection, so it amplifies al...

Hi Tim, I believe someone explained it best when they said that there were two ways that amp makers deal with the noise produced in the audible band due to the switching frequency being too low. One way creates an overly smooth top end with missin...

 New class AB amp from Benchmark ABH2 also utilizes SMPS resulting in 132dB dynamic range.   They had to cut costs somewhere to hit that $2995 price point. The dynamic range and THD numbers, while appearing to be unusually good, may be partly t...

I've been living with ICEPower based amps for six months, I don't hear any of the issues being discussed, and my speakers have extension beyond 30kHz.   Some folks hear the issues and others don't. Some folks are really sensitive to phase/point...

I had the Ice Amp 125ASX2 and it was awful.

The Rogue Pharaoh is an integrated though? Emotiva Monoblocks running 600 watts of power with their best preamp compared to a 185 watt Rogue integrated?? You can’t compare pricing on monoblocks plus preamp with an integrated that has a fraction of...

I keep reading the negative comments on class D amps here and then listen to my Devialet 1000 to Maggie 20.7 setup for flaws. I know the Devialet is a class D hybrid design..... but the system just blows away all the other amps I have tried. For ...

Fast forward 6 months and I can truly say the Emotiva gear was mid fi. The Rogue gear outclasses in in every way. I don't care that Magnepan says to avoid Class D. They are wrong for making such a blanket statement, and I was wrong for heeding t...

  The real strengths of Class D are low cost, high efficiency (about 85%) and because of the latter, smaller size as large heatsinks are not as important.Lower cost for manufactures, which seems to result in higher margins instead of reduced re...

I am in the market for new amplification, moving on from my trusty Krell KAV250 and was considering giving class d a try again. I say again as about 3 years ago i tried a pair of bel canto 500m mononblocks and found them to be so cold and steril... 
Elac power DAC Bash Amp
Sorry about the bump but does anyone have any comments on BASH?

Companies such as Devialet are creating hybrid AD Amplifiers. In theory, that could be the best of both worlds with sound & efficiency. Are the hybrid amps subject to the same issues with phase & bandwidth?

I recall when I was in college I could hear well to 20khz. I know because I ran tests.I also found it much harder to get sound that was not fatiguing. This is back in analog days even. These days I know I cannot hear to that extent which is norm...
