New classe delta preamp and classe stereo amp?

@fredrik222 According to classe, you can stick these in a cabinet because they have the fans. as long as the back of the cabinet is open. Have you ever pulled the front grille off the amp and look at the filter or blow it out?

@oldaudiophile That is the delta series I am talking about. There is no way for me to test them at home.I have the accuphase e5000 already and if I want to, I have the option to trade it in for the Delta pre and Delta stereo amp. I used to own the classe cp500 pre and ca2200 amp for 20 years. Got bored and got the accuphase e5000. It's great, just thinking of this option on the new stuff.

@duketbrd88 yep, I am aware of it that you can, but I’d like glass so you can see it, since it is a pretty piece. 
 

I have not pulled off the front grill, but maybe I will do.

just for reference, the fan doesn’t register on a spl meter.

@fredrik222 That's good about he fan noise. It's a good looking unit for sure.

@fredrik222 With regard to racks, have you checked out Salamander?

I've got one of their Synergy modular racks without any front, side or back panels and this works quite well with my McIntosh integrated.  My MAC doesn't have a fan and, frankly, stays quite cool to the touch, even after many hours of duty but MAC recommends good ventilation.  Even with a glass front panel, dust will always find a way, if you know what I mean.  If you kept it covered when not in use, you could still remove the cover and watch the meters dance around when the music is playing.

Another thought:  is your amp positioned in proximity to a back wall?  Since the fan exhausts to the rear of the casework, any chance what you're hearing is actually the fan pushing air up against a back wall that is too close and not fan noise itself?  The shop I was in when I spent time with this amp had it on a rather tall rack, as I indicated in my initial post, and the wall behind it was probably a good 3' away.  Of course, I didn't know it had a fan at the time and, as such, wasn't making a point of listening for that sort of thing.  However, I was close enough to this beast and spent more than a few minutes eyeing and coveting it without noticing any fan noise at all.  Maybe dust accumulation on the fan?  I know this is nitpicking but just trying to help.  Bottom line:  If ya can't hear it when the music's playing; ain't a problem!

Enjoy!  Go play some music!
