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.

@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”.
