Buckeye Amps: Hypex NCx500 Official Thread

Oh, and they would all be mono block configuration!

Oh DuH! Silly me thought you would be happy with 2 power supplies....LoL. I fear the thermal characteristics of such a 11 channel mono-block configuration would be challenging to say the least. Unless it was a unconventional case size and odd dimensions.

I hate saying no to customers but as most have heard me say before: spending the money on Purifi/NCx modules for speakers past either a 2ch or 3ch LCR setup is not really worth the price difference over say the NC252 or NC502.

Hi Dylan, with the advent of Dolby Atmos music which makes extensive use of the surrounds, I think this has changed.

Even in those setups, I would bet a good amount an audible difference coming out of the surrounds or even Atmos would not be discernible between an NC502 vs a Purifi/NCx

This!

How many channels do you want and what is the use case?

I’m just curious about upcoming options. This is for an 11 channel setup. Will likely go with a 3 channel + 8 channel amp.

Thanks, that makes sense. As @Buckeye Amps has pointed out previously, the surround channels are usually adequately served by more value-focused amplification.

Even my use case for active speakers does not require much power in the upper frequencies. If I go for the overkill, could still be done with 2 2-channel amps. For packaging, one 4-channel amp would be convenient. This would allow for those with needing more power for surround speakers to use 2 of them.

Yes. The Hypex amps with built in power supplies are more cost effective, but I do wonder what’s possible as an alternative to products like the NAD Purifi models.

Any future plans for 2 channels 1ET7040SA?


900W X 2 channels would be great option indeed, or 900W x 3 channels

I've now had my NCx500 2 channel amp from buckeye for a few days. And it's amazing.

Hooked up to Audiovector R3 Arrete speakers which are ultra revealing, This amp makes these speakers sing!

Happy Holidays to all! Please be aware that any new orders placed as of today will not ship out until after Christmas. Thank you to everyone for making Buckeye Amps a huge success in the audio world!

I am very hopeful available before Christmas. The production run normally takes 8wks but as I said, we are doing a few things to speed that up.

Definitely missed the early eta of Q3 I had hoped for. But in the end it is better everything is tested and working perfectly, of course.

Hi Dylan, are we still on track for shipments of the 3-channel before Christmas?

It’s going to be very close.

During 3rd party testing, it was thought there was an issue with the SMPS, so we spent the last two weeks rushing diagnostics only to find there was no issue and it was a simple user error during their own testing metric.

Production was paused during that 2wk period out of caution but has resumed.

 

[Buckeye Amps]

I can reassure, though, that this SMPS has been through the RINGER for testing. So while I have been way off the mark on when I had hoped to get these shipping, the end is worth the wait.

 

[Chesapeake HT]

Looking forward to getting it, but do what is needed! Thanks Dylan

The final SMPS2K version with the extended heatsink.

After days of listening sessions I started to fall in love with this amplifier.

The amplifier passed the torture testing 10Hz @ 3 channels and all other tests.

 

[MicroAudio]

Some midnight testing while the production is ongoing.

For those waiting on their 3ch NCx orders, I am spending the next two weeks of my “vacation” building your amps with everything ready to go (minus the SMPS) so the moment I receive the SMPS’ I can drop them in, test, and ship super quick.

 

[sweetchaos]

I didn't see anything mentioned about this yet, so I'd ask.

Any potential plans to ship a unit to Amir for a review?

I have a friend who I can convince to buy this amp, if there's a review available.

Any updates in regards to shipping units?
