Buckeye Amps musicality? Not measurements, musicality....


Hey Everyone.... question, I am contemplating the Buckeye Amps 9040 Purifi monoblocks. I am, at the same time, considering the Musical Fidelity M6x 250.5 (5 channel) all of this in an effort to run my LCR up front. (Arendal 1723 THX Monitors)  - everything I read from Dylan at Buckeye and hear from his interviews in YouTube videos all surrounds measurements. Let's assume that every amp, in particular these two options, measure incredibly well. I get that.

But I also get that amp measurements are only a piece of how an amp ACTUALLY SOUNDS in the real world with my room and my speakers.  Which is why its a red flag that Buckeye hides behind measurements as the end-all-be-all of buying an amplifier. If measurements were the absolute end of the discussion, there wouldn't have been a Class A or A/B amp sold in the last 5 years. I get that the Purifi stuff measures well, incredibly well, but to never say anything in public forums or in public interviews about how your amps actually sound or how musical they are compounds and continues the notion that while Class D measures insanely well, they sound cold, brittle, analytical, bright, shout'y and too forward. Class D or no Class D, it boils down to the amp designers' actual implementation of the technology in how it sounds, e.g. the input stage, the output stage, the signal path, etc.

So what I'm looking for I suppose is owners of exceptional Class A/B amps (like Musical Fidelity, Parasound, Rotel et al) who have made that leap of faith to the Purifi Buckeye either 7040 or 9040 modules and how your experience has been.....  ??  Thanks immensely!

You ask a great question. Measurement will tell you very little about how they sound. 

I got this from an AI summary of Buckeye. This description is a resounding no on musical / natural sounding... if that is what you want. This has all the characteristics of being on the analytical side... not musical and warm.

Buckeye Amps are known for their neutral and transparent sound, allowing the natural character of the music to come through without coloration. They are praised for their detail, clarity, and ability to reproduce sound with accuracy. While they don't add warmth or smoothing to the sound, they excel at revealing the nuances and imaging of recordings. 

You have to verify from other reviews. Reading lots of reviews and you learn key words that give away the sound. 

@mapman  I mean, yeah, maybe a little. I just know there's so much more to an amp than measurements, so to never say a single word about the input stage, or the potential sound quality differences in SMPS compared to LPS, it just concerns me. In Class A, sometimes the crappy measuring ones sound spectacular. Not super crappy, but you see what I mean. I wish the Buckeye amp company owners and amp designers of the world would say something, anything other than "our amps measure the best on the planet."

Like, OK, that's one factor in sound quality, let's hear more, why did you choose XYZ capacitors, why didn't you use a linear power supply (Axiom Audio Amps for instance) - why do you use a Hypex power supply over XYZ power supply and how do you think that affects sound quality.........   All of that stuff is important and not necessarily marketing hype.

Hmm the Buckeyes sound pretty “musical” to me based on that description. 😉 

Of course the other things in the system will have a say as well.  

Some vendors in that space offer different op amp options with their amps to tailor the sound from more neutral  and accurate for some to warmer sounding for others.  Your choice!   That’s a very practical way to go.
