RE: Firmware 8.0 - PhilP - 03-Jun-2015 @Antoine - Thanks for your detailed response. I'm thinking about upgrading my system may try a P3 or P5 at the same time... RE: Firmware 8.0 - Antoine - 03-Jun-2015 Great PhilP, enjoy the auditioning, I'm curious to know what you think of it!

No one can state an opinion on the P3/P5/P10 based solely on having heard these older models! I did what Kerry suggested and put the Dev 250 straight into the wall. Indeed it made a diference for a better midband presence and fluidity, although with some loss in bass articulation (it´s just my first impression on two of my reference CDs). The rest of the system remained plugged on the PPPremier. My next adventure is to finally have a go with the V8... RE: Firmware 8.0 - Antoine - 03-Jun-2015 Happy to read that! My experience with the P3 (which is a different machine than the PPP) is different but I guess that's already quite clear from my earlier posts. RE: Firmware 8.0 - Manoet - 03-Jun-2015 Antoine, I have serious doubts about these units, if now running closer to 30 watts continuous at 'normal' listening volumes being able to run continuously at 20X that (600 watts) and holding together for any length of time. Hard for me to imagine anything currently running at/near 30 watts at ~45C only running 60-65C at 20X the power consumption. Seems to me people would start smelling melting plastic, cap wraps, phenolic, insulation and not be able to touch these things without oven mitts within a half hour of power-up. What am I missing? RE: Firmware 8.0 - AaronG - 04-Jun-2015 I have the PS Audio Premier for my 120 and it is barely hot to the touch, less than the Devialet. It makes a very noticeable difference -- but I live in the city with lots of crap in the power lines. It's a bit shocking when you see how variable the voltage is going into the unit, and a relief that it all goes out 120v RE: Firmware 8.0 - MusicFirst - 04-Jun-2015 I agree, Devialet's choice of the words 'at least' are a mistake and the word 'maximum' should have been used: At its rated output and their stated 85% power supply efficiency, the D250 consumes 588 watts RMS into 6 ohms (250wpcx2ch)/.85 and 889 watts RMS into 4 ohm loads (378x2)/.85. If one assumes +6db of dynamic headroom (6-9 db is typical in high end SS amplifiers) the peak power requirement is between 2352 watts (6 db headroom) to 4704 watts (9 db headroom) depending on the design of the power supply and the ADH amplifier. So Devialet's assertions are far from cow dung. For me music is all about the dynamics! So if one ignores the real world power requirements of your amplifiers (and other components), you do so at your own peril. In this case it is never about the RMS power. It is about the peaks. I was off this thread branch, but misunderstandings are rampant. Kerry B.A.Sc. P. Eng RE: Firmware 8.0 - Manoet - 04-Jun-2015 I just nominated a 'power' section in the suggestion box as I feel its important enough and doubt when this thread runs its course that'll be the end of it since its part & parcel to everything we dabble at here. But hey, that's just me. RE: Firmware 8.0 - Antoine - 04-Jun-2015 Just one final response to wrap it up from my side. I think Manoet is right in his post in the suggestion box, we're going very off topic here. Unfortunately we're really missing the detailed specs here. The P3 for example can supply up to 9200W of short term peak power (P=V*I, 9200=230V*40A) we however don't know for how long. The tightly digitally controlled power supply inside the Devialet could use up to 3000W in peaks, again we don't know for how long. I'm also not sure under what real world conditions this may happen but I don't feel it'll happen at every kickdrum at volume levels that are just tolerable. But of course I don't have the numbers and measurements so I could be wrong and of course it is system dependent as some loudspeakers are easier loads than others. "Mitigating factors' to prevent current starvation is the power storage inside the Devialets (13.200μF of capacitance) but I suppose the possible energy reserves inside the P3 are already taken into account in the mentioned 40A. Fortunately I have never noticed a shortage of power/restriction of dynamics but my situation is even more difficult than just described as I also use an active subwoofer which of course also has it's own internal power storage reserves. And finally my Devialet has a 2nd order high pass filter active @ 80Hz so doesn't have to work as hard in the lower frequencies compared to a setup without an active sub.

From the PS Audio P3 Owner's Manual: "All P3’s labeled US or JP can output a continuous load of up to 800 Volt-Amps of pure, regulated AC, with peak momentary output capabilities of up to 1000 Volt-Amps. All P3’s labeled EX, GR, or UK can output a continuous load of up to 900 Volt-Amps of pure, regulated AC, with peak momentary output capabilities of up to 1000 Volt-Amps." Kerry |
