Hi DavidHi Alan,
Is there plans to release the P422 with the Purifi 1ET7040SA unit?
Hi AlanHi David
Not at the moment. TBH as either a physically larger 2.2kW PSU, or 2 of the monoblock PSUs would be required, we would have to have a larger case than the P422. So the pricing for a P502 wouldn't be far off a pair of monoblocks.
Secondly the potential maximum 20 amp mains current draw does start to become an issue in 110volt territories. Although it's very unlikely to occur with music as opposed to test signals.
Just be wary of some manufacturers trying to use Hypex smps1200a400 PSUs with the 1et7040sa. They are too low a voltage. You won't get the rated 500watts into 4 ohms.
Hi @thin bLueHi Alan
My I ask a question?
Do you have any plan to use newer 1ET9040BA amps?
I got it!Hi @thin bLue
No plans as of yet. I saw and discussed the amp with Bruno when we met in Munich a few weeks back.
At the end of the day they will have very slightly more noise and distortion than the existing offerings. So my question is, do we really need more power? The 1et7040 in our p501 amp can deliver 500 Watts into 4 ohms and 950 Watts into 2 ohms.
There are very few domestic hifi speakers that can handle more than 500 Watts, so I see the market as very small for such an amplifier.
When integrated with a buffer amp (remember you will need even more gain to achieve the higher output voltage to achieve the higher power output), its gain will increase the noise figure, so maybe not much difference. certainly not anything that has any real world relevance. All the Purifi amps are astoundingly quiet.I got it!
Thanks for confirm that!
I heard some rumors about 1et9040ba will have great power (same 40A as 1et7040, 1% thd 1500W @ 2Ohm) with lower noise of ~8 uV before.
But, as you confirmed, with slightly more noise, it looks we can only get marginal very gains with massive price increase can not be justified at this moment.
Maybe it'll fit for boutique amp made for multiple-8", 10" or larger- low-noise high xmax-Purifi-ed speakers for the future.
Yes, I'm sure I can't hear any differences with well designed Purifi Amps.When integrated with a buffer amp, its gain will increase the noise figure, so maybe not much difference. certainly not anything that has any real world relevance. All the Purifi amps are astoundingly quiet.
No power figures were confirmed, but considering the supply voltage I was quoted, your estimate of power seems about right.
