I'm interested in the Ncore400 vs. any of the Anaview modules AMS-1000-1300...even though listed as deiscontinued are still readily available as existing stock.

I have seen a couple of guys that have compared AMS anaview new moduels with hypex n core and all who did said they prefer AMS anaview... notably, the somewhat famous audiovisjion, who BUILDS hypex amps and sells them, admitted that at the very least he prefered the amphion amp (which is using the anaview AMS modules) to the hypex ncore with the amphion one18 loudspeakers. reference: https://www.gearslutz.com/board/high...d-test-87.html post 2591 «Though I build the hypex Ncore amps in Norway I have to admit the Anaview´s modules from Amphion is a better match. They somehow bring out a level of resolution and focus that is even more impressive. I would not hesitate to use any of the two though. I tested the Anaview against a couple of amps from Harman & Kardon today costing twice the price of the Amphion and witness the transparency ,liniarity, focus and phase response just falling apart. It was quite sad to see the face of the buyer when he heard the difference.» Also, I have found a couple of guys who has went from hypex to anaview. I have gather that the new ams modules compared to the older aml modules arent that far appart though. so users with D-Sonic commercial amps that uses the anaview old modules has already said that they prefered the anaview to hypex.

Hi Stephane,

Did you finish your project ?

Any feedback would be appreciate here !

Thanks in advance.

Hi everyone,

my AMS1000-2600 will soon arrive, and I wonder how much gain does it have.
My main source is a Raspberry PI with on board I2S DAC and it would be perfect not to have
a preamp needed. There is a digital hardware based gain, but if something goes wrong and
the Amp gets a 2V feed this could possibly damage my NEAR 50Me speakers (8Ohm 90dBW)?
Could I use just a potentiometer in front of the input, and would it be acceptable (thinking about a low impedance one)?
Or, is there any possibility to mod the Amp with variable gain.

Any suggestions regarding input gain is very appreciated!
Cheers to all.

We chose to set the gain on the Anaview modules so that 2Vpk (1,4Vrms) will clip them at nominal mains voltage.

Hi Pabo,

I'm currently using a pair of AMS1000-2600 in BTL configuration. My preamp is a Benchmark DAC2 with an output impedance of 135 Ohms. The interconnection is balanced using XLR mogami cables, 3 m lenght.

Do you think the preamp - amp matching is adecuate? Or should I consider getting an input buffer?
