Oh boy. As much as I like the progress, the old modules just came out? I'd like some investment security.
I hear you, but in addition to being for a different use case as others have noted - I guess this is more or less Purifi's version of the Hypex1200, yes? - keep in mind that this module is also rated officially at 500wpc into 4 ohms - the 960wpc rating is for 2 ohms.
And remember that the original Purifi module is rated at 400wpc into 4 ohms.
In the real world, it appears from Amir's measurements that the 400wpc Purifi (and Hypex) modules actually produce something closer to 250wpc into 4 ohms, if we're talking the full 20Hz-20kHz at very low levels of distortion.
Using that metric, this new module would likely provide just over 300 wpc into 4 ohms compared to about 250 wpc into 4 ohms for the current module. That extra 50 wpc is not likely to mean much of anything in 99+% of home listening use cases, when you consider that you have to double or quadruple the wattage of an amp to get much louder playback capability.
Finally, this new module has virtually the same
gain as the old one: 13dB on the new one vs 12.7dB on the old one (IIRC). So again, you're not really going to hear any volume difference with the new one vs the old one. So unless you have speakers that present a 2 ohm load to an amp, or unless the current Purifi module does not provide enough power (or gain, even when put in an amp with buffer stages) for your needs - in other words unless the current Purifi module won't work at all for you in your situation - then I don't see any benefit to this module over the current one. As others have said, this is not a sonic upgrade or a meaningful power upgrade
if you've already got a Purifi-based amp and it's meeting your needs.
