hypex

I'm looking to replace my amplifier that is responsible for the bass driver (8 Ohm) in my speakers. I'm trying to find a used pair due to costs. I'm looking at either Hypex NC2K or Powersoft DigiMod 3004PFC2. The later because I can currently find it ready built for sale used; there are no used...

I Hello! bought the M10 V3. But I have to turn it up to -10 to -5db to hear vinyl records loud enough and about -20db for anything else. So I bought the Fosi Box X5 pre amp. It's louder (even at the lowest gain) than the internal phono pre amp. But there is a hum which I can't eliminate. I will...

Hello together, I know the title sounds a bit cynical, but I'm wondering this myself. If there is already a similar thread, please move mine there. There are now some very good Class-D amplifiers based on the TI TPA3255 chip. The best (according to Amir's measurements) currently seems to be...

I bought a Buckeye Hypex NC252MP 8-channel amp a few years ago. In the course of using it in my surround system, two of the Hypex modules have failed within a 14-month period. It's possible these failures were triggered by adverse input signals, but an amplifier that can be destroyed simply...

I've been looking into class D amplifiers for a while now, and the hypex / purifi amps seem to always be on top. I know they use some aggressive feedback, but the main question I have is how they get high resolution from their somewhat low frequency delta sigma modulator. I assume they are using...

Hi everyone, I have some thoughts/questions about creating filters for my new speakers. I built the kingroy mk3 kit by seas and want to use the fir capability of the hypex amps. Right now I use the dsp preset 1 provided by Seas. I used the mmm technique to measure a sphere around my listening...

What are the issues in using linear power supply (transformer + bridge rectifier assembly etc.) with class D amplifiers? Idle energy loss too high? Efficiency? Magnetic field interferences? Price? Almost every established traditional brand (like Denon, Marantz, etc.) used linear PSU in their...

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...

I currently have two Trinnov Amplitude8 (8 channel amp) amps that have a linear power supply with <80W idle consumption each. Even so they generate more heat that I like so I'm looking for a "pure" class D /SMPS combo as replacement. To make sure I can't go wrong I was looking at a...

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...

Hi i want to build studio monitors for mixing, mastering and also just listening to music. A few things are already set. They will be 3 way with seperate closed boxes for bass and mid and i will use a hypex fa253 for dsp and amplification. The hypex plates can do fir filters since the latest...

Hi amigos, I'm coming back to the forefront with a new project. This time I focused on the Sylph Audio FB100 module, based on a TPA3251 and an advanced implementation of the PFFB. Voltage Gain is factory set @ 14dB (5V/V) on this module. So I intended to couple it to my DAC SMSL D6s which has...

Hi, This is my second post in ASR. I appreciate the effort of the community being objective. So, I will try to be as objective as I can be. I may fail though. I would like to buy a class D amplifier to for my stereo system and I need help deciding among the different options: Purifi, NC502...

Hi all, quick question. I’m looking at two amps from Apollon. The Purifi 1ET7040SA DM Luc Dual Mono Amplifier and the Hypex NCx500 DM Lux Dual Mono Amplifier. The Purifi is power rating is 250/500/950 watts at 8/4/2 ohms. The Hypex power rating is 380/700/700 watts at 8/4/2 ohms. Do people...

Does anyone know what kind of class d amps that brands like Dynaudio Professional, Adam, Genelec use inside their active speakers. Infineon, Hypex, others? Thanks
