New Purifi amplifiers coming

[mocenigo]

What is the recommended power supply for max output for these 9040 modules when used as monoblocks?

Dual rail 45V (I.e. providing 45 and -45V). That’s where the “90” in the name comes from.

Apollon are also doing a single channel amp for 2995 Euro

Audiophonics are taking orders for their 1et9040ba two channel amplifier (for 2990!) which seems to use the same slim chassis as their other Purifi & Nilai stereo amps:

AUDIOPHONICS HPA-DM750ET Power Amplifier Purifi 1ET9040BA

The Audiophonics HPA-DM750ET is a Class D power amplifier featuring dual mono architecture. Integrating two Purifi 1ET9040BA amplifier modules and two independent Hypex SMPS1200A180 power supply boards,

I noticed that Apollon say they use the Hypex SMPS1200A400, but that's a 64V supply, which I think is wrong for 1et9040ba.

I asked Audiophonics, out of curiosity, what they are doing for the input buffer. I hope that they are not reusing their single opamp buffer, because that would not give justice to the 1et9040ba, but I fear that this is exactly what they are doing.

I dunno, I had the data sheet for several weeks already ;-)

I guess you have friends in the right places. Unfortunately for the rest of us, we have to rely on Purifi to publish them to their web site, which they haven't as of yet done.

Seems to work pretty well with the 1ET400A, as measured here.

the Weiss opamp is something special

What does it have that is so special ?
Any measurements ?

True, but the important data haven’t changed significantly from the picture of the slides presented at the Munich Hi-End. And the pictures ARE in this thread.

But the 1ET9040BA has significant lower noise and distortion values.

A S/N ratio of about 150Db.

Measurements might not give much useful information.
If you didn't see it, Amir tested the difference between stock, Sonic Imagery 990ENH and Sparkos Pro SS2590 discrete op-amps in this thread:

Discrete OpAmp Review: Sonic Imagery vs Sparkos

Recently I reviewed the Nord Three SE 1ET400A Dual Mono Stereo Amplifier. That unit came with the Sonic Imagery's 990ENH discrete operational amplifier ("opamp") in the buffer stage (pre-amplifier). The owner then ordered a set of Sparkos Pro SS2590 discrete opamps. This gave me a chance to...

The stock TI OPA1612A actually measured the best.

What is the recommended power supply for max output for these 9040 modules when used as monoblocks?

Audiophonics say they use the Hypex SMPS1200A180, which is a 46V supply.
The spec sheet says +30V to +45V max.
It's low voltage because it's a bridged amp.
The Connex SMPS2000RxE could provide more current. It's only 40V, so less 8 ohm power, but I think Connex offer customisation options.

CONNEX SMPS2000RxE Switched mode Power supply module 2000W / 40V - Audiophonics

The switching power supply SMPS2000RxE is a very high efficiency model capable of developing a rated power of 2000 Watts.

There are probably some suitable options from Micro Audio, but I'm not sure I want to go there.

And don't forget prices on their site do not include VAT for EU countries, that is added extra on cart. So total real cost is almost 7,000 Euros and 7,500 for the monoblocks for EU customers

I made a simulation "all options" with personalized paint and I arrive at 7,268.40€ for France which corresponds more or less to the price of two AHB2 ;(the price is exactly the same as for the Hypex PNC2k )

If I did the calc right given the 2 x 1200 watt@2 Ohm with the given max efficiency of 96% for the amps + PSU ,this case should have the ability to dissipate more than 150 watt.
It certainly does not look like it given the size and the small heatshinks and I don't believe they use active cooling.

(Calcs,here )

 

[welwynnick]

There are several ways of looking at the price.

• It's not too much to ask for what may be the best amplifier ever made.
• They will probably sell every one they can make.
• With limited initial supply, residual values might even go up.
• Audiophonics are a lot cheaper though, and there will be other options in future.
• The benefit is probably more in bragging rights than actual audible benefit.
• There are several other Hypex and Purifi amps that are good enough.
• You don't even have to buy one at all.

 

[mocenigo]

Too bad that there is no 45V version of the SMPS3k...

Connex has a 2K at 40V, but I am quite sure they could provide a 45V version.

 

[Buckeye Amps]

Micro Audio will have a 46v that is going to fit the bill for a mono build.

 

[goryu]

It really is hard to understand why Purifi, which has long claimed it would be offering its own supplies, is now on the third model in their amp line with no SMPS of their own anywhere in sight.

It's coming. Eventually...

So is fusion power I am told.

Then we won't need efficient amplifiers any more

Exactly. So let's all just wait, right?

 

[MAB]

A S/N ratio of about 150Db.

I think measurements, would help.
What's a 'Db'?
