D amps

+1 @atmasphere 

@hgeifman May I know which specific vendor's Hypex-based amp you or your friends have purchased from?  Knowing the specific Hypex-based amp vendor might be necessary, as different vendors often implement subtle design choices that can influence sound quality beyond pure measurements. Brands like Apollon, Nord, and VTV Amplifier are some well-known names offering Hypex or Purifi modules, each with a slightly different approach to things like power supply and housing design, which can impact the listening experience.

@lanx0003. My first class D amp were custom built Hypex NCore NC400 bridged amplifiers. I had them for a short tine and replaced them with Mola Mola NC1200 mono blocks. I was disappointed with the sound quality and sold them. As I stated above, they sounded very good at first but the more I listened, the less I liked them.

This was several years ago and I have no other experience with class d amps.

I currently own the Musical Fidelity M-6Si integrated amp. I am VERY surprised it sounds this good. I am very happy with my decision. The M6si offers excellent performance, facilities, and power. As per the Musical Fidelity web site “Internally, the M6si is configured as 2 independent monobloc power amps with a separate preamp. It is, in fact, a preamp with 2 monobloc power amps that just happen to share the same casework. The M6si has 220wpc. It has very low distortion, outstanding noise ratio and extremely flat frequency response”.

+1 @atmasphere, I agree it is the overall design of the amp that makes it sound great.  

Hello bernal737  May I recommend the power ampss from Starke sound?  They make 4 channel and 8 channel amps. They make their own modules. I have six of their four channel models and they drive the Linkwitz 521-4 systems superbly. I also use them with Magnepan LRS, LRS+, and the Golden Ear BRS speakers. They have an iorn grip on the speakers they drive and give excellent results with everything I connect them to. Dayton Audio has a very tiny 2 way kit using passive radiators on each side and it sounds very well when the Starkes drive them. I also have two of the Purifi Audio EVAL-1 kits that sound very good also. But the Starkes are just a bit smoother and sweeter on the top end. Starke gives you a trial period also. Highly recommended. Happy Listening! 

Y'all haven't heard ClassDaudio.com amps yet looks like. I own two. Fits in your palm, 5 lbs, & are dazzling. Cheap too.
