Buckeye 3 Channel Purifi Amplifier Review (2nd)

[emilkoz]

Not sure what you are getting at, please further explain. Since most speakers have two, three, or more drivers which produce sound.

Generally speaking a person wouldn’t buy a three channel amp and use it as a mono block

Sorry and yes as Julf guessed, I'm in the active camp .

Yes exactly ... my Buckeye Purify based 2-ch power amp drives Neat Acoustics Motive 1 speaker's tweeter + midrange drivers, while nCore nc502mp based 2-ch power amp is driving bass drivers ... no issues with tweeters at all

I assume @emilkoz is thinking about driving the speaker actively, with a separate amp/channel for each driver - and wondering if 250W for just the tweeter wouldn't be overkill.

At my listening levels I am definitely wasting watts (probably using a minuscule fraction of available wattage per channel) but I don't care ... I could easily go with one of these amps and not bi-amp my speakers ... but now I have virtually unlimited power available per channel, giving me effortless pure sound and that's what matters to me ... these nCore and Purify based power amps are so cheap compared to class A / AB power amps that can measure similarly and that have similar wattage per channel (they are 10x heavier too)

It won’t be the 0.5W as the Hypex SMPS will be on standby mode and not off it using Auto or 12v.

One change we hope to make late this year is better control of the SMPS to further bring down idle/standby wattage

Dylan, have you made the SMPS changes to bring down idle/standby wattage yet for currently shipping amps? If so, any power saving at idle advantages to using 12v trigger vs Auto. Looking forward to receiving my new Buckeye amps soon!

No change yet. That will likely be a new year roll out/implementation as there a few other things involved simultaneously.

The 2kW will not be for the 3ch Purifi. But there is another version from Micro Audio that will be used.

When would the Micro Audio PS version of the 3-ch Purifi be available? Mine's on order now, and idle power usage is always a concern here.

That is another in the new year decision/time table

Regarding idle, I have been monitoring a 3ch Purifi build inside my rack for a few months now and internal temp of the amp never goes above 80F (room is 74F ambient). So aside from the slightly elevated wattage draw in idle, long term temps are not really an issue/factor.
