..google is open and free,contact some university,study,search..ask from:
Synaps, to auditory perception and sound processing in the brain.
and ask if there is "acceleration of the particles of air," or there is only a constant speed (which depends on the support of propagation), etc etc. search relation with electric audio enveloope (if you find)..
simple!
..Thank Mr.Push_Pull.
Spot on. The correct price for a product is as much as customers are willing to pay, but not more. I salute Hypex for their price policy, and wish them much success now and in the future.
I have reluctantly moved this thread to Vendors Bazaar. Despite the fact that many think this is an obvious thing to do, the thread was not started by Hypex, and that has been the primary reason it has not been moved until now. The ideal situation would be if Hypex had their own commercial forum here, but they do not. If they did the thread would have been moved long ago.

I'm considering purchasing the NCORE. I already own a Sure TK2050 2x100W amplifier and I'm reasonably satisfied with it's sound reproduction.
Can anyone offer comparisons of HYPEX modules in general or specifically the NCORE vs the Sure TK2050 or similar amps?
My goal with upgrading is to improve bass response and gain more texture and richness in the mid-range. I'm most concerned with texture and resolution of mid range detail as I tend to listen to acoustics solos (Cello, Violin, Piano, Guitar) though my musical tastes run the gamut of musical styles (yes even polka).
If all I will gain is the more esoteric "sound stage" or "air" I'm not interested. Especially considering the TK2050 is $150 to build with a basic case and PS.

Hi, I am new to DIY audio and I am considering building an amp with the ncore. I am planning to use a tube preamp. My question is this. Do I need to use a circuit on input for protection from overcurrents during power-on and power-off of the preamp? Also is it a good idea to use tube preamp and if not what is prefferable? Forgive me if the questions are lame.
The NC400 needs about 2VRMS to deliver it's full power of some 200 watts in an 8 ohm load, so first of all you might consider if an active preamp is what you need.
When you want to tailor the sound to your liking you could try whatever preamp to achieve that, but for the most "neutral" sound a mere buffered passive preamp could well be the ticket.
Thanks pieter t, I am considering both, but since I already have the preamp I am thinking of trying the preamp first. My point is if I ever want to use it with the tube preamp, is there I chance I will damage the ncore if I don't use a protection circuit?
Not likely, but be sure that there is no DC offset at the preamp output (not sure if the ncore is input capacitor coupled).
That is one thing I've wondered about.
I've been stealthily planning in the future to direct couple an NCore or UcD from a WM8741 but wonder if I should add caps to handle DC or if the amp modules already handle that.
Dear friends,
From the comments on the smps supply opposed to a classic linear one, it does sound like there is a consensus that the "new" technology has surpassed the old one also on sound quality. Please correct me here, as I am trying to get a hold on the possibilities that comes with smps´s over linear PS designs...
I have a few Q´s regarding how to read the specs and chose a proper smps for various applications that I hope someone would be helpful to answer:
As I get it the smps tech generally regulates in a different way to that of the linear PS´s as the recharging circles are not restricted to the main frequency but designed to be fx 100kHz. This should mean that smps should be "stiffer" than linear supplies, no?
This should also mean that the distortion artifacts produced by the charging is moved up in frequency according to reduced charging circles, no? Hence probably also related to subjectively different audible signature, no?
Generally, what counts in smps design to achieve the very best audible performance of the active circuitry hooked on it?
How big audible differences should one expect from one smps design to another? Has anyone tried various smps designs on the same circuitry to assess this?
Does power rating still count, or does it just need to be adequate. In the linear days a 1000VA donut would blow a way a 200 VA one although only a few watts was actually used... Does this translate into the smps´s too, hence more authority can be gained by getting a more "stiff" supply by fx choosing a 1200watt over a 400 watt one?
Also when making linear PS´s there is little doubt regarding getting greater performance from dedicated rails per channel opposed to share one big pair of +/- VDC. Does this also count for smps´s, and if so which of the hypex offerings does offer plural dedicated pair´s VDC rails? Or do one need to purchase a dedicated smps for each channel to get the very best performance?
I would be greatful for any comments.
cheers,

When the preamp has an output cap why put another one at the input of the power amp?
Capacitors are evil
so avoid them when possible.
