Hi Guidoo
I was so excited to receive the 825 last Thursday. Setting up took quite awhile as a large effort was made to put this monster into the Finite Elemente Pagode Aps rack as the space just only fit the monster. After playing for 2 hours I realized the potential of what it can do to my sonus faber Amati Anniversario. It presents a bigger soundstage better imaging and detail except that its raw and lack the finesse as compared to my previous 625. The bass was already better than 625. This is without doubt as the 825 packs with much more power. However, the next day when I switched the amp on again, i heard a loud crank sound inside the chassis and thereafter there was no sound coming out from the speaker. Yes no signal. Following day, the dealer took it back promising to replace a new one. This happening prompted me to learn more about class d amp. I saw this website below and read it had to say. I m particular concern that it said that the switch mode power supply is so complex that if it stay on operating pass 7 years, then you are lucky. More often than not it wouldn't survive pass the 7 year mark. What it is trying to say is that the reliability is limited in a switch mode power supply and that it virtually can't be repaired AT ALL. What's your take on this?
