I want to replace my NAD c315 with a lab gruppen iP900 or cambridge 840A V2.
I now the cambridge audio 840A..but not the lab gruppen... My dealer tells me about the iP900 which apparently has a very good sounding,dynamic,...The only drawback for me it's the fan noise...I don't know if it's audible.
So if you have any experiences with lab gruppen or if someone could advice me.
An amp with a fan will either be tiny/compact with no room to 'breathe' or in the case of lower powered stuff, Class 'A'. In either case, fans are generally noisy unless special low speed or specialty fans are used. You need to check it out to see if it is distracting or runs too warm. If you have it enclosed, that may help with the noise, but cook it even faster.
my small dish / satellite receiver has a very tiny fan which you can hear during quiet passages in the sound track, later at night and when the fridge in the other room is off.
Who's your dealer....sounds like they could be a pro-audio / DJ supply shop? That amp with the fan...that's commercial stuff. If you're attracted to the rugged stuff...take a look at Bryston...no fans, by-the-way.
goin' on 30 years ago I built a 4" box fan for the back of my Carver Cube. No matter WHAT I did to it, there was never any heat build up. Of course, the fan was really loud, but that was ok, since the music was WAY louder! And I mean near redline for hours.
