Buckeye Amps: Hypex NCx500 Official Thread

Nice system!

I almost pulled the trigger on the ESL X and C, then had an unexpected amount of work fall into my lap and ended up with Classic 9s and Focus C18. They have been sitting NIB for a month now, can't wait to hear them.

I'm looking real hard at the 3 channel NCx and Purifi 3 channel jobs, leaning toward NCx. I'm sure the Purifi has plenty of power, but am drawn to the NCx for its massive 2 ohm capabilities.
Thanks. Been a long time coming, but slowly building up my dream system. I liked the NCx for it's 2ohm capability as well. The ESLs can dip to 1.6ohm so this amp was about as good as it can get. Super happy w/ the NCx - tons of super clean power.

Yeah, I am looking at 0.8 ohms. That's pushing me toward the NCx, for sure.

I see you also have dual SB3000s. I have two but am only using one at the moment. Excellent sub for the money, you want more, just add more. I'm thinking of adding one or two more, as I have an AVR that has four sub outs.

What is the rating of your circuit breaker 15amp?

Love my subs but can't imagine having more than two of them. I looked a the Classic 9's but thought a passive tower + subs would be the best of all worlds for various music genre's (classical, bossa nova, electronic, rock) and then LFE for the subs for movies. Just noticed the new Denon A1H has balanced inputs. Seriously hope that trend catches on so we can use desktop DACs. Haven't read about an AVP or AVR that can touch that level of quality yet.

What do you think the benefit of more than 2 subs would be?
 
I want to say a HUGE thank you to Dylan @Buckeye Amps! He built me a custom chassis 4 channel Hypex NCx500 (Qty 2 - NCx500's and power supplies in the same chassis - two amps one chassis)...I paired it with some Martin Logan Motion XT F200’s - bi-amp’d, running an AudioControl Maestro X9S pre-amp, using Roon/Tidal (the AudioControl does full MQA unfolding and is Roon Ready, so 100% compatible)...AMAZING! He built me 14 channels of the NC502's (qty 2 - 4 channel and a 6 channel) so I was using one of the 4 channels NC502's while I was waiting, but the newer NCx502's with his selectable buffer stages, allowed me to dial things in. Thanks again my friend!
 
Hasn't the whole MQA scam unfolded by now?
Hello Julf,
I knew someone would have to bring "it" up LOL...not really a scam, it is simply another high-res streaming protocol...and I get it, it costs money for licensing, pay-to-play, is it better or not than FLAC or WAV, etc...I have read more than most I can guarantee it. I have Tidal and ROON subscriptions and they support it, so I use it. I personally think I can hear the difference between most MQA and FLAC, at least on this setup, not on most of the other combinations that I have tested (I am a dealer so I get to test a lot of different setups)...and don't get me wrong...it isn't like "oh this must be MQA or FLAC". I would never tell a customer they need to drop their FLAC/WAV and go with MQA, etc...it is more about making people aware of the various technologies, and seeing what they prefer.

Interested to see what Spotify "Supremium" looks like later this year and what Tidal's FLAC stream looks like too.

Indeed, I saw that announcement the other day..."competition" is good, as it typically keeps pricing down with multiple "equal" options.

The claims made about MQA were a scam. And if you hear a difference between FLAC and MQA, it is a sign that MQA distorts/colors/changes the signal in some way, as the FLAC version *is* the original wave.

Thanks again for your opinion...but again, that is all it is...your opinion.

Don't want to continue polluting this thread, and there is really very little I care to say to the "evidence-based science is just an opinion" crowd.
 
Did you ask Hypex about warranty or is this just your opinion? I asked about mods and they clearly stated they would void warranty.

Hypex use of RTV to reduce shock and vibration issues is by design. So would be part of the testing they do. While acknowledging your suggestion to test first, not everyone has a good thermal camera. A pair of scissors is much more accessible.



I have had these discussions with Hypex and it would be relevant. It could also be relevant to the manufacturer as the modules are warrantied by Hypex to them. I considered becoming an authorized Hypex repairer and my understanding is Hypex would honor their warranty regardless. No buck passing as you allude.



One camera angle on one case design is hardly a major problem. I have other cases and the LED brightness is not a major concern. Am sure Buckeye or his customers are smart enough to employ simple mitigations if needed.:)
PS.....ANYBODY now can afford a GOOD thermal camera.
 
What do you think the benefit of more than 2 subs would be?
More room coverage for multiple listeners. Distortion would be lowered at bass FR. Those are two basic improvements. There could be some benefits when Dirac Live Bass Control comes out, which is my main reason for wanting more subs.

As it is, there is only one listening position in this room at this time and one sub with XT32 correction is doing a fine job.

The Classic 9 is all-passive. I spent a week with the 15A and loved it, but don't see the point in powered subs with ARC as I will be using active subs with the mains high passed.

The A1H is attractive and I am a fan of XLR. I'm gonna wait for the Dirac dust to settle before considering moving up the Denon chain to a flagship, whatever it may be. All I need for now is 5.2 capability, with the option to go 5.4.4.
 
What is the rating of your circuit breaker 15amp?
Yes. I have 2 available and will spread out the load, but it is not really necessary. I am in an apartment and average SPL levels are 75-85 dBC.

ML says to use many hours (40, 90, I can't remember) a 90dB to break in the panels. That ain't gonna happen.

At sub frequencies, where human ears don't have much sense of direction, even one or two provide full room coverage. The only benefit of multiple subs I can think of is for evening/averaging out resonances.

If you haven't, look into distributed bass arrays and the use of 3 or 4 subs. Geddes wrote on the subject extensively.
