    Hypex Ncore vs D chip amps - sound quality?

    If you take the different power output options (through internal or external PSUs) off the table, do the current Class D chip amps measure up to a Hypex Ncore? Will a TPA3255+PFFB sound the same top-to-bottom as a NC252MP at 2 watts with a 4-ohm speaker? Or is there still something...

    Good morning to all those who read these lines of this new 3ad. I would like to ask those who have experience in amplifiers such as Apollon Audio, Rouge Audio Design (which I believe, but I'm not sure, has closed its doors), VTV AMPLIFIER and others of the same genre, if you recommend switching...

    Class D Amp Module Replacement

    Hi all, I have a Bel Canto S300 with one module that is out of commission. I was going to try a warranty fix but then I see how simple the replacement would be to do myself. My 1st thought was to replace both modules with new ones from parts-express. This is the closest match I could find...

    "ASH-400 Project" Sylph Audio FB-100 Stereo Module with advanced PFFB

    JBL 705P Circuitry?

    As mentioned elsewhere I've just upgraded to a pair of JBL 705Ps. To feed them I've assembled PiCorePlayer on a Pi4 with a HifiBerry SPDIF HAT. This feeds the AES input nicely. So it's an all-digital signal path. Or is it? Does anyone here have an insight into the internals of the 70x series...
