D amps


Anyone try the new class D amps with Nautilus 802 speakers?

@bernal737, I agree with the comments above. I owned the HYPEX NCore NC400 bridged class D amplifiers and did not like them. I switched to the Mola Mola Tambaqui HYPEX NC1200 DAC and still did not like the class D sound on these amps. As described above, they lacked the subtly, feeling, resolution, sparkle, air and imaging of my MusicalFidelity class AB amps that replaced them.

When I first installed them, after break in, they sounded very good. The problem is the more I listed, the less I liked them. I replaced them with the Musical Fidelity integrated CLASS A/B amp M6si. It 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.

There are some newer class D designs on the market today using the GaN class D amp. For example, please see the Atma-Sphere ClassD GaN mono amplifiers. Purifi Class D amps are another example. Jeff Rowland Design Group also uses a class D design but I know nothing about it.

Based on my Class D experience, I am not looking at any Class D amps.

I can tell you about a excellent pair of monoblocks GanFet technologies 

and under $2500 a pair coming out in. 2-3 weeks I bought their proto types 

and had a few of my Highend Furutech items added ,better fuses Hifi tuning copper 

nottoo expensive ,it comes with WBT. Loudspeaker terminals 

power supply technologies I have not seen in any other brand ,NASA trickle down. 
very small but powerful, class D audio   Dot.  Com . And a great little review 

enjoy the music  dot com on their  stereo amp ,a year before these new ones. 
keep an 👁️ eye out. 

Musical Fidelity leans towards a warmer sound than say Cambridge Audio or most Class Ds. Class D is not for warmth. Hypex is probably the popular modern implementation that comes closer than Purifi and definitely Pascal. I’ve heard Atmasphere Class D and the sound was more like his tube amps than not.

So don’t make the mistake of thinking all Class D is the same. Some vendors offer different op amps up front that adjusts the sound to different preferences. VTV for example.

Personally, with B&W, which I have owned, I’d probably lean towards Pascal or Purifi. Hypex ncore done well would be perfectly fine.  I tend to lean towards detail rather than warmth.  

I know a lot of people will hate me for this comment but please try the Java hifi single shot amplifier. It’s the best amplifier I have had besides some SET gear period.
