@andrew@March Audio Thanks. What, with all the talk of the input buffer, is the input impedance / recommended pre-amp output impedance? (Existing valve pre-amp is 600Ohms)
But have they be cryogenically treated?We are moving all amps over to the ETI Research speaker post to allow easier access for large cables and spades, but they are also better being solid copper gold plated and caressed by blonde virgins before installation.
But have they be cryogenically treated?
@g29 A unit is on its way tomorrow. ...
Does anyone know the label of switch fets in Hypex Ncore amps?
Just a quck update on the forthcoming P701 monoblock power amp.
I was going to be releasing a NC500 based mono block amp next month, however the NC1200 module has just been released and I will be utlising this module instead. The NC1200 has basically the same or better performance than the NC500. Major difference is that its drive capabilities have been greatly improved. The NC1200 8 ohm rating is 400 watts, 4 ohm is 700 watts and 2 ohms is 1200 watts. Current output is now 38 amps. The NC500 would manage 400 Watts, 700 Watts and 550 Watts and 26 amps respectively. As such this will drive the most difficult of speaker loads. Noise and distortion levels really are superb. In the typically used range, around 5 watts THD is about 0.0007% or -103 dB.
Note the buffered 128dB SNR and 20uV noise levels

Hi @AnLaoJinAs a large floor speaker (parallel subwoofer) user, I need NC2K. . The power of NC1.2K is not enough to meet my needs. . Although NC1.2K 1200W seems very attractive, but according to the theory of the best performance at 50%, NC2K is still needed
I think your situation dwells more in the "want" area of emotion than the "need" area of technology.As a large floor speaker (parallel subwoofer) user, I need NC2K. .

ELAC Concentro,4 subwoofers are connected in parallel, and the impedance is very low. I use a 100W power amplifier to push it, and the sound pressure is very small, and the power amplifier is protected.Hi @AnLaoJin
May I ask what speakers you are using? Very few domestic speakers will handle the 2.5kW the nc2k is capable of delivering into 4 ohms.
There is no basis to presume any amplifier will give best performance at 50% power. I will post the THD+Noise plots for the nc1200 and nc2k later to show how they perform.
Here is what the manufacturer specifies. With NC1200 you would be fine.ELAC Concentro,4 subwoofers are connected in parallel, and the impedance is very low. I use a 100W power amplifier to push it, and the sound pressure is very small, and the power amplifier is protected.
But the 400/700/1200W of the NC1200 seems to be very amazing. In fact, they are at extremely high distortion output power. If it becomes 0.01% distortion output power, it may only be half of the original. . 200/500/700W???Here is what the manufacturer specifies. With NC1200 you would be fine.
