Buckeye Amps: New US based Hypex multichannel amplifier builder, line-up announcement!

@Matias that's a thread idea for you, if you'd like.

Simply comparing Hypex and Purify technology, I mean.

None of the other technologies.

I can assist with the creation of Google Sheets, if needed.

Just a thought...
 
I'll think about it. What to compare, how to present, what is considered poor, average, good and excellent etc.
 
Hi, I am new here I am going to be buying the PURIFI 1ET400A 3-Channel and trying to figure out which cables I need. My receiver only has RCA so I am looking at these cables: https://www.bluejeanscable.com/store/balancedaudio/balanced-to-unbalanced-cables.htm but I cant tell which connector I need.

I don't know if they include a wiring diagram, and how their price compared to Monoprice's, that does include the wiring diagram that looks correct based on Hypex's recommendation. I have used Monoprice's and know they worked well, i.e. no audible ground loop hum, no hiss either.


For $11 each, the Monoprice ones are safe bet.

Agreed, but for my money I buy them direct from Monoprice.
The juggernaut Amazon doesn't need a cut of my cash. ;)

I did try to link Monoprice but the wiring diagram there would not work for some reason. It's there but remained tiny when clicked on.
 
Actually, that's the one brand Dylan suggested staying away from for RCA/XLR cables in the past. I guess they can introduce some noise.
There was a run of bad ones at one time it seems, based on a wide survey of owners over a couple of years. I believe they are good to be used again for a while now.

This. Per Monoprice website they still have pin 1 of the XLR connected to sleeve via pin 3, which is not the recommended Hypex configuration. All explained in the Hypex Legacy Pin 1 problem document referenced several times in this thread.

Just wanted to come back here and give Dylan some kudos!

My amp, which has been running almost continually for over a year now in the studio, had a little problem. The "auto sense" feature that turns it on/off with activity stopped working correctly. It wasn't a huge issue as it just required me to turn it on/off manually every time I used it. But I had gotten so used to the convenience of just leaving it on that I was spoiled!

I sent Dylan a note about it, fully expecting to have to pay for a part or something as the unit was just over 2 years old. I had not taken it apart, so I didn't really know what was involved. But I have built a number of power amps myself and am comfortable with such things.

Turns out the circuitry is built into an input board that has the XLR input jacks for every channel on it and runs the length of the chassis. Dylan promptly sent me a new board, arrived in a very quick 2 days!! No Charge.

I have yet to install it as I just received it. But I wanted to come straight here and say what awesome customer service!! You can't ask for any more than that.

If you've been putting off buying a Buckeye Amp for fear of the small company service, fear no more, the service is excellent!

great to hear! Mines been used every day for about two years now with no issues whatsoever. I have the smaller one, works great for my dbr62's.

In full agreement: I always try to buy direct from the manufacturer (or one of their authorized sales outlets when I can.
 
So are the Monoprice recommended or not by Dylan? What brand of balanced to unbalanced cable had he previously recommended?

I can tell you Monoprice premier series unbalanced to balanced ones are good but don't know about balanced to unbalanced as I never have need to use those. Buckeye amps usually come with balanced inputs only so I don't know why you need balanced to unbalanced.

The only issue with Monoprice is it seems there is random variation in their quality/being properly wired. I have had customers report ordering x number at a time and for some reason one of them will not work properly (introduces hum). When they work, they work just fine.

I have only used the premier series and never experienced any issues. They show the wiring diagram on their website so I know they are wired correctly. May be their low priced versions have lower quality?

If in doubt, just buy from Amazon so it will be easy to return for full refund if you end up with defective ones.
