Wow! Could you please show me the way to find about "to hear hf roll off on the hypex amps"?I haven’t blind tested them but I’d imagine none unless power comes into play. Some people claim to hear hf roll off on the hypex amps, at 48 I’m not one of them.
As I inferred-if you can hear this then you must be part dolphin:Wow! Could you please show me the way to find about "to hear hf roll off on the hypex amps"?
Sounds pretty bad
So, you would prefer Purifi?If you listen to "modern" music, badly produced music and low or very low DR, without acoustic or electric instruments, the Hypex NC252 would be a good choice I think.
A lot of traditional Class D amps have "problems" with tweeter + good/very good acoustic recordings -> a non-credible reproduction.
Purifi is other level, a very good amplifier. The only downside, for now, is that it is usually accompanied by Hypex SMPS, with capacitors of questionable quality.
"Soon" may be a bit optimistic..Presumably soon, Purifi will sell his own.
YesCan any of these amps (BoXem, Apollon etc) being used as a Mono Amp in bridgemode like the NAD C298?
Looking at the BoXem site i do not see anything written about this. Is there any info/data available in bridge mode?
Hi @daniboun !I would go for Purifi Modules + the brand new Hypex PSU SMPS 3KA400 (with 2X separate rails). + Neurochrome Buffers.
You will get the best of the Purifi potential )
Purifi 1ET400A / Hypex NC500 Input Buffer
This input stage features a fully differential output, which allows you to drive the Purifi and Hypex amps to clipping - even with an unbalanced source - with extremely low distortion. This input buffer is the perfect match for a Purifi 1ET400A Class D amplifier DIY kit. OEM pricing and custom...neurochrome.com
Like this but with only 2 Purifi modules :
Sorry to say it, but all the diy cases for me look like something what should be inside server racks, but not on my tv furnitureBecause they measure very well and they are very transparent :
It has a selectable gain
Plug-and-play connection with Hypex SMPS psu
True differential output with common-mode feedback
The buffer can be disabled by removing two resistors
etc

With a little patience of sewing oil) : If you get a GX285 Alu Case, made in Italy by the way + the Purifi Modules + SMPS 3KA400 + Neurochrome buffers, you can have a beautiful amp for a fair price )
Example with my GX285 case :
btw, how is it comparing that Purifi amp?

Do you feel any difference?
Should I go for NCore if I don't need that power?
