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.
 
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.
 
Much more secure and tight connection. Better than bananas or spades for sure.
Yep!
While speakon are better, my point was that for most of people, it is not common to be a mandatory criteria for choosing an amp in non pro/pa world.
 
It would be nice if SpeakOn connectors were currently available on Buckeye amps again without having to buy a rack mount case. You got them at the right time @Rottmannash.

Boxem has SpeakON connectors available for all of his NCx500 amps. They also have a nice looking case, auto off with a 0.5W draw after 10 minutes idle and an amazing build quality. Looks like a bit more attention to detail.
As is always the case, I will never be able to please everyone.
 
It is nice to have the choice of Buckeye Amps or boXem audio for amplification.
 
I know this is sort of off topic, but I have to just say that after some 30 years of first Usenet and then forums of all sorts, ASR is the Best.Forum.Ever! Hands down, no contest! I love this place! People don't get really worked up about stuff they don't give a poop about. Amir, you are a gift, a national treasure, thank you so much for putting up with all of us!
Yes, Although many people would prefer to listen rather than measure, this still gives us an objective comparison.
 
In my case I will be actively amping my 3 way speakers so I need 3 channels per side. One three channel amp per speaker plus another 2 channel amp for the 4 subs...
Which speaker are you using?
 
On Buckeye site power rating is specified as follows
450 watts @ 2 ohm, 425 watts @ 4 ohm, 225 watts @ 8 ohm

Measurements on first page of review, are great, but show lower output before distortion gets bad?
So, what do values on Buckeye site represent?

1% distortion
 
I'm curious, are the power vs distortion charts in the review indicative of continuous power?
 
What's to say about my new 2 channel version, other than "price to performance" and "measurements"? A couple small things.

First, price and performance got this on my list, but what sold me was their warranty page. Not the warranty (which is good), but the page. After reading that, I decided this is the kind of company I would like to do business with.

Second, there was a delay in my order due to a supply order being split. I found communication on this to be top notch, I could expect no better. That includes a prompt response and an unsolicited follow up, both times giving me a "hope to ship by" date. I had the amp by the hope to ship by date.

Third, the connectors (discussed up thread). They make a noise when engaged and are quite secure. When would I want fully locking connectors? Live performance, studio, where accidental failure is more likely and more costly than in a home environment. But I do understand why people might like fully locking over spring locking, I'm just not one of those people.

Fourth, I do like 3 gain stages for current and future flexibility. Better than one or two!

As for the performance? I've never had an amp this accurate before, so... My first reaction was "Wow, the bass!". Second, "this reminds me of headphones" because it was dead quiet. Third, great separation in the sound stage. Everything else was better too, but those were the biggest difference between this and the fosi v3 it replaced.

This amp fit my needs, and the company was good to deal with. The price was right, the performance as the measurements would lead me to expect. So a good deal, and a good company to work with.
 
I know that it shouldn't make any difference because it measures almost perfect, but I wonder why the standard PSU cable isn't twisted and/or shielded?

This really bugs people with OCD like myself...
 
Since it is plugged I guess you can unplug it, twist it, and plug it back, no?
