Buckeye Amps: 2nd Generation Purifi EIGENTAKT 1ET9040BA Amplifier

@Buckeye Amps

Do you have an internal photo of the amp to share?
First post. Even though that was a picture of the prototype build, it is essentially how the final build looks. Will take a picture of the Micro Audio before shipping out your order once the next batch of cases arrive this week

Might want to add one to the product page on your web site. Thanks.
 
I hate to resort to analogies, and vision is not my field, but I've read (and tested way back in college) that a similar thing happens with light sources. Side-by-side we can readily detect small variations in light output from two sources relative to each other, but if you put one bulb in then a little later swap it (or adjust a dimmer) for one of slightly more or less output and walk out and back into the room, it takes a much larger variation to be noticed in the absolute sense.
In general, one can think of our brains being very good at contrast (or edge) detection in most of the senses and less descerning in identifying absolute magnitudes. Thus, with A/B audible comparisons and side-by-side visual comparisons, one can detect finer gradations than with spaced or independent presentations of the same stimuli.

Thanks Kal, appreciate the insight from an expert!

Well said Doctor Rubinson!

Anyone, who already got their 1ET9040 builds care to share how do they sound, please? Any differences/similarities with 1ET400?
Thank you!
noiseless, the amps sound great. I couldn't be more pleased coming from Class A monoblocks.
It's all up to your upstream components now and recording. Played some CDs that sounded horrible and some sounded sublime.
Streaming sounds great, vinyl even better than before for some reason.
I have no way to compare to the 1ET400.

Nice work Dylan!

Compared to the class A’s do you notice a difference sonically? What brand of class A did you have?
 
Monarchy SM-70 pro.
Not really. If I could describe it in one word it would be better presence. Maybe grip as others have said. The Buckeye monos are very nice, very happy.
Contrary to many who believe they don't need a break in period, I believe it. I've just left them on for past week + and they "seem" to have gotten better out of the box.

Now they're all going to demand you arrange a proper blind A/B test involving time travel! God help me if they ever see the cones I have my setup on :)

No worries, I'm armed with silence.

Show us the cones!! :)

No, we simply disregard the subjective, personal perceptions that don't correlate with objective reality.
 
Once Dylan ships me the mono’s I will put giant power cables, cones, and every audiophile cringe thing I can think of on them and post pics ;)
someone beat you to it...

FWIW, our AP unit (baseline) has an inherently higher H2 then would be expected from an AP unit.
