Yes, it's beautiful and I should have bought two of them instead. I curse Fred for not trying to upsell me.

Back to boXem... Uncle Arthur (4216/E2) is on the way....
Uncle Arthur is at home for some time.
Yesterday tried it for about one hour...beautiful machine, small, nice, working like hell....
Will come back with more details

I agree
So how come some guys still believe in magical sound? And pay unrealistic privés for an amp and crave about the supposed sounding of their new amp?

What music exactly?
What volume?
The 228 be is high efficiency
Easy load too

Is the Wiim Amp Ultra now on your list of amps to review? Will you get a unit on loan?
They seem to have some good stuff but rather like Buckeye I find the websites a mess. Hypex series, Purifi, jeez folks sort them by like mono/stereo/multi and then by price, make it easy for us.
Following the two additional very nice reviews from amplifiers using second gen Purifi modules, I may encourage the readers to compare the noise performance of the amplifiers at equivalent gain. Or reversely, which gain is necessary for a given noise performance. Our direct competitor need their gain set to 12.3 dB (sensitivity 9V) to reach our 20 dB (sensitivity 4V) performance and our 26 dB performance (2V sensitivity) is the same as their 20 dB performance.
So, at the risk of repeating myself, buffer matters.
So, at the risk of repeating myself, buffer matters.
Still not apples vs apples ... you are using purifi modules that are rated 450w and you achieve 78% max power on a single amp module with the hypex smps. Your competitor achieves 99% for a module... feels way better to have maybe even headroom to drive both modules with a higher load. Noise comparisons on that level are not really audible, but missing power on an smps is if you drive it with low frequencies.
You're not wrong, I just checked out Boxem's website, not easy to nav at all... Buckeye is marginally better.. Nord and Apollon better again but still have the hypex/purifi split.
non related but I went to check and your website is pretty sluggish at the moment
may have cost you a sale or two
I don't think he was comparing himself to Buckeye and Micro Audio SMPS, but rather Apollon and Hypex SMPS too (notice the word "direct competitor", as in similar build quality and also in the EU).
If somebody here is not comparing apples to apples, it may be somebody else than me
Thanks for the feedback. What did you find difficult to navigate?
Also thanks for the feedback. DDOS attacks had stopped since a few months but they restarted end of last year.
Indeed.
That's true, which is why I find the THDN/SNRD bar chart pretty much useless, since it compares amps at different gains. One amp with 26dB of gain would measure worse than one with a 15dB gain. The latter would be 'heralded' as the champion
.Your point about the quality of the buffer design is well taken. Another instrumental test would be to measure amplifier output noise with inputs shorted at different gains. Spectral plots (from 20Hz to 20kHz) from all offered gain options, overlaid one on top of the other, would show how quiet or clean the noise floor of the amp is.
I prefer my Boxem Purifi Arthur 4215/E2 to my Buckeye Purifi.
A. Boxem supports 27.2dB gain while Buckeye is limited to 25dB.
B. The Boxem case looks quite a bit nicer.
C. The Buckeye shipped with extra distortion from steel binding post tabs. (Luckily, ASR found the issue and the design was fixed)
D. Boxem amp was thoroughly tested before shipping it to me.
E. The Boxem A 4216/E2 offers SpeakOn connectors. That's a nice upgrade right there.
F. Both companies work with Purifi parts but the skill to optimize buffer boards, connections and do it right the first time makes a difference.
While the underlying parts are the same, the build, buffer and attention to detail by a quality integrator adds value.
Now we need the tariffs removed so we can start importing these fantastic Boxem amps into the USA again without silly import penalties.

Hopefully we get the right decision on that soon.

Hey Fred, strangely when I try your site, I get the below;
boXem sàrl
403 Forbidden
You cannot access this store from your country. We apologize for the inconvenience.
Cloudfare DDOS protection may be worth looking at, plus I think it's got a free tier for personal/hobby type sites or $20 a month for Pro.
The above is a geo-restriction though on IP's from certain Countries, not DDoS related.

Not me who said it - I am not a potential purchaser at the moment, but I can give you some feedback.
For me, what is missing is an overview of your product range and a clear understanding of the differences between each model.
For example - do I need Arthur, or A series? From looking at your site, I have no idea.
Then when I click on "A Series," I can select between 20 different items - but the only info shown is the model number and price. I can't even see if they are mono, stereo, or multi-channel. Same on the Arthur page except for fewer options. The only way to find out what each model offers is to drill down to view the detailed specifications. At this point, if I were a potential purchaser, I might just give up. As a non-purchaser, I already have - meaning I am less likely to return if I want a new amp in the future.
For me - as a minimum, you need:
1 - An "in your face" (meaning right there on the home page) description of the headline differences between your Arthur and A series ranges.
2 - On each range's home page - under each item, a statement of channel number and rated power is an absolute minimum. Better would be a table with a line per item, a thumbnail picture in the left column with the model number, and showing key specifications for each. For me, I'd also want to be able to easily see which modules the amp is based on. Being able to filter the table for channel number, and module type would be good.
Hope that helps.
