Buckeye 3 Channel Purifi Amp Review

[Buckeye Amps]

@Buckeye Amps Can you explain if that is the case and if so why not Eval 1 design is used?

Wanted to have everything on one board that could be scaled to account for different configurations.

For a strictly 1 or 2 channel design, the EVAL1 one would save a few bucks, but when we decided to offer 3ch and also have the ability to go up to 5ch in the future, we'd need our own board to be cost effective anyways.
Same thought process as incorporating the 7040SA and offering it in up to a 3ch configuration one day as well.

Having our own buffer board that can be configured and scaled as needed seems the best route. We obviously have this hiccup to sort out but I'm confident.

Couldn’t you have copied the Eval 1 board design? I assume the name Eval means evaluate, hence you are free to use the design, which is published like chip companies’ application notes.

We did. The EVAL1 schematic was used when designing our schematic.

So your design is the same but the measurements are not? If even the PSU is the same than one will assume it is the layout that is causing the problem.

One of the avenues we are exploring, among others, for the distortion rise.

Good luck

And I'm saying that "healthy debating" expressly doesn't involve trying to tell others what they should prefer from looks.

And it really turns healthy debating into threads like this one, which is now utter trash when it started out good.

All thanks to one guy who thought he knew what everyone else should like and pay for in terms of looks. Instead of just saying "this isn't for me - I'd want a nicer enclosure" he says "this is wrong and bad for everyone" essentially.

We went from a thread which was the epitome of the good that ASR does and now we're in the dregs talking about looks and meta about looks. Signal to noise has gone to pot.

OK, you must be speaking of someone else, but your quote is quite vague, I didn't pay attention to that "one guy" I guess.

By the way, I think the silkscreening on the back looks really good—clear font and nice and tidy labeling—as well as the logo on the front. People who are complaining about the bent sheet metal construction don’t realize that most audio components are made of sheet metal, either aluminum or steel, of similar thickness and quality with the same sort of gaps and tolerances. What they are missing, I guess, are thick faceplates made of aluminum or plastic that are purely cosmetic and add nothing to the sound, although they might cover up any gaps, etc.

Anyone else reading this and really hoping that Dylan puts out a special edition amp that looks like a bunch of bananas?

If you understood the price for each of the three Purifi modules you would understand it doesn't leave much remaining for casework, labor and overhead. Most low cost manufacturers are charging near $1600 for a stereo Purifi amp - this particular unit contains a third Purifi module as well. If the performance is able to match the best Purifi amps it would be a real bargain with the case just as it is.

Have you considered that I might understand that and still have the same opinion? Here's why...

If you're going to spend ~1500 on an amp why scrimp on the appearance for the sake of saving maybe £100? Are people shopping in this range really so price sensitive that a 5-10% price hike to cover the cost of a nice case going to shop for an ugly cheaper model instead? I don't see it.

To each their own

 

[Duckeenie]

Exactly! I thought this board was about objective approaches. The staunch objectivists seem to stray from their SOP when it suits them.
Funny how that works.
If you dont like it, dont buy it .... just quit the bitching OK? Move along to a different thread (not speaking to you @xaxxon)

How is the hivemind these days?

Question for @Buckeye Amps and Buckeye Amp owners—I assume that the sole LED on the front of the case doubles as the clipping indicator and the error indicator. I also assume that if there is an error, the error indicator blinks a certain number of times on startup to indicate what the error code is. Am I correct and can you provide more detail? Thanks!

If there is an error, the LED turns static Red color. When clipping, the LED color will blink Orange.

Yes, in many cases people are that price sensitive. I have a very nice main system and now I'm building a second system. I spent enough on the main system and set a more strict budget on this set up. If I'm only willing to spend X-dollars tops on an amp, do you recommend I buy a lower performing amp in a jewel case or the higher performing one in a plain case? I choose performance, it's my prerogative to make those decisions and appreciate having the options.

So there isn’t an error code, but rather just a generic error indication? Is there any way to tell the difference between a protection circuit error, or overheating, or a fault that needs service?

Really do appreciate you coming by here to post. It’s not always easy, but I appreciate you taking the good and the bad with patience and class. You‘re going to be top on my list when I make my next purchase.

I'd like to ask the reverse: are you really so price sensitive that a high-performance amp that has a plain case and costs $1500 somehow puts it beyond the pale because it's too expensive? To be frank my 8-channel buckeye is (now) the least expensive component in my rig. From where I sit, it can have a cheap box because, compared to other solutions with equal or better performance, it is cheap. You say it's ugly but that only makes me cry all the way to the bank.

Its a business decision no doubt driven by cost conscious customer requests for high performance amplification without any superfluous features. Seems reasonable judging by the ridicule often aimed at components that cater for the eyes rather than performance in the reviews here.
Buckeye appears to have been approached by potential customers that would like a nicer case but his base must be strong enough for him not to turn away from his existing business model.
It’s a choice for customers to make for themselves and besides, people set budgets for a multitude of reasons and the sensible ones stick to it.

I totally agree with this. I personally am putting this amp in a back room on a rack and don’t care at all how it looks.
