Class d recomendation for esl speaker

[Pepe]

I’m about to make an upgrade from my Sure AA-AB32313 + Meanwell HLG-320-36A.
The speakers are Final sound 1000i, they do not dip to crazy low Ohms in the bass like most ESL speakers. A benign 4 Ohm load is/was promissed by Final sound.

The options I’m looking at are:

Hypes nCore board/diy
Ice edge board/diy

Crown DCi analog

Should I add other amps to the list?

The reason for upgrade is that I find the Sure AA-AB32313 + Meanwell HLG-320-36A combo is lacking in ”bass tightness”

Edit: Crown CTs has redicoulusly high damping factor From lowest hz to high hz. I’ll add it to my list allso.

Hello,

Personally I would go with the NCOR400. It handles speakers down to 2 ohms with no problems. One I have sounds quite good and I have to wonder how much better one could get. On a limited budget and few local DIY friends, likely won't get to compare directly anytime soon. FWIW.

Also, the NCOR has so little RF problem that I have my tuner on top of the amp case with no sign of any noise at all. Extremely good RF control.

(I am using the SMPS - SMPS1200A400 so as to make sure the supply is not limited in any way. Could go with one of the smaller 600 which can power two NCOR400's pretty well, may limit extremely loud playing of peaks, but works pretty well according to others.)

Hard to go wrong with Hypex, whether UCD or nCore.

TPA325x, very good amp.

Thank you all for the replies. Good to get conformation that the ncore is a good bet.
The turn up quite regularly on the Swedish secondhand Market. I’ll keep my eyes open and fingers crossed that some will turn up for sale soon.

TPA325x, very good amp.

Is that amplifier similar to the sure amp I’m using at the moment? Or is it much supperior? What about ncore vs tpa325x (is that 1 or 5?, is it just the power rating that differ?)

 

[Pepe]

Hypex offerings look promesing. Just learned that the fusion plate amps run ncore. They look to be of extremely good value. For example fa122 With 2x125w ncore, dac, dsp And Preamplifier! Can’t find anything about damping factor, s/n ratio, distortion levers etc..

Hmm, seems the sloppy bass could be an common esl problem (extremely high q in the bass range) and not reladet till my amp.
I might relief the esl from the bass and let ob woofers do that job insted.
