[This an updated posting. The measurement result was better than anything else on the market at any price  ]
I will post more information on the website but here's the summary.  We have listened to early production P-9 last week and totally impressed.  P-9 is expected to retail for $2950 and it will match the performance of Mark Levinson No.326S $10,000 (yes, we have this preamp in our lab to do AB comparison). The software still need some revision (some cool features such as the motorized Apls volume pot will slowly go back to its previous position when power on!). Some distributors and reviewers will be getting them in January but customers will get the volume shipment starting from end of Feb. This is a major break-through from Nuforce. By the way, we can't claim all the credit. The core of P-9 is designed by Demain Martin. We did the integration.

Outstanding news Jason!   Looking forward to upgrading my P-8/Ref9's to P-9/RefSE as soon as humanly possible.  Can you provide a few pix of the new units?

[beachbum]

yea jason, how about some pics.  aa

[rustydoglim]

Will have pic in another day or two. We're waiting for photo from the studio.
0.0004% THD+N, Zero phase shift. Very scary. Click on the link on P-9 product page to see the plot. Show me another preamp that come close to it  .  Wait till you hear it at CES 2007.
Well, for those of you who doesn't know Demian Martin, read his brief profile on our product page.

Are the 3 power supplies SMPS or linear?  Thanks!

[beachbum]

hey jason if it sounds as good as it looks, you will have another winner, thanks for the pics,

The audio stages are powered by 2 separate linear supplies. In our CES demo, we are using an SMPS for the logic supply, although we may change it to a linear for production.

Take a look at the plot http://www.nuforce.com/plots_p9.htm
No other preamp in the world can handle a 125KHz square wave input as clean as P9.

           Jason,
                 How much gain does this unit offer ?

Why do you want to pass 125k square waves, ie what does the output of your companion power amp look like with realistic loads at full power if you do?

thanks

Gain is 5dB.   It can be adjusted up to 20dB of gain (factory option).

That's what it takes to preserve music's transients.

I don't know what source you might be using, but what would your companion power amp look like with realistic loads at full power if you do?

THD, phase-shifts, and bandwidth limitation are cumulative, so a preamp that does not corrupt music would be ideal, and P-9 is Nuforce's attempt to accomplish the goal of 'a straight wire with gain'.   Indeed when the preamp 'no longer matters', then the limiting factors in the music reproduction are now the loudspeakers and the power amplifiers, these are no yet 'a straight wire with gain', as of today, but surely we are working towards that goal.

You can refer to the measurement plots of Nuforce amplifier published on our web site.

Casey,

Considering that the P-9 is a two chassis design, do you think it would be possible to include a DAC with a couple of digital inputs? The AVP 16 has a preamp and a DAC section and that price point it is unbelieveable IMO. The P-9 with a great built in DAC would be a killer combination.

[beachbum]

can anyone who has a p-9 up and running in there system give some feedback on your thoughts, and comments, i have ref 9ses and its seems like a no brainer to add a p-9, any replies would be appreciated, thanks

[rustydoglim]

P-9 has been in field testing with 8 distributors around the world at trade shows and dealers visits during the past few weeks.  It was also sent to an indpendent lab/review. The comment was that the spec is the best ever measured and the sound is world class.  I will publish more plots when I get the chance.

During the field testing, we found some minor bugs and will be sending the revised units to distributors again for qualification.  P-9 will likely ship to dealers around Mid March even through we are producing them at end of Feb.  We want to ensure a perfect release of this world class preamp.

[beachbum]

ok jason thanks for the update, have been using a marsh tubed preamp lately, and will sure try the p-9 when available, mike
