My understanding is that both the D800 and Pro had been powered up for many hours, overnight I think. So after a listening session with the D800, temperatures checked as follows: A=43° D=42° S=41°. It was at this point that we noticed that DPM was on. (I think the way V10 is working is tricking people with default options etc.) This is worth mentioning because having realised the D800 listening session was with DPM, to keep things simple, we ran the Pro with DPM. Alasdair is of the view that DPM does not make much difference. I tend to agree with this but I have found some stuff at home with the Blades to sound a touch better without DPM, so in casual listening I might keep it on, but sometimes it goes off if I'm having a serious listen to something. So, my Pro observations above were with DPM on. So to temperatures on the Pro. I was perhaps expecting these to be similar or lower, with all the new cooling material, solid copper base, higher power PSU, and so on, but no! The Pro was reading A=57° D=48° S=50°. Ouch!! It has been noted a few time in the past that Devialet's can run quite hot when they are new, they then settle down after some use. So this is interesting, does the Pro run hotter, or is it simply a case of OAC's demo unit being only two weeks old. It does offer the tantalising prospect that OAC's demo Pro is not quite at it's best yet, but if it sounded that good when not at it's best, it'll be happy days when it settles down!
Analogue=57 with DPM ON? Did I understand You well?
IMO this is too hot. With DPM OFF it will be for sure more than 61 degrees...
Using 1000 with low sensitivity loudspeakers, volume -10dB and with DPM OFF will cause even 65 or more degrees...not very good...
maybe Devialet should construct 1000 100% copper chassis...?
