Help My Krell amp is too big.

How's the ventilation around the EVO? And how do you like it? Congrats on a nice purchase too. : )

I don't have an FPB 400cx. I have the FPB 600. The 402 fits but just by a little where the 600 was just too big.

Hiernote : you confirm that the Evo 402 is really better sounding thant the fpb series amps ? On what particular point ?
Thanks for help.

The EVOs get hot as heck too, and the 402 is still only a inch and half less in width, a little less than an inch taller, about 3 inches deeper than the FPB 400cx (??) you have. If your cabinet is only 22 inches deep, doesn't this make things worse for you?

Thanks for the great responses. After considering everything said, I plan to get a Krell 402 Evolution and sell the FPB 600. Thanks again!

as a builder i suggest you talk to your contractor. even if the cabinet is finished and installed he should STILL be able to work out something more than likely. you sound as tho it is not finished however... is there some 'other' reason for wanting to switch amps? as mentioned before, i hope that space is well vented ;^)

I would say go with either the EVO 402
or step down to a 400cx
You'll hear a drastic improvement with the 402 and should not be giving anything up except pounds going with a 400cx

Unless you are in a shear-wall configuration it should be easy to get a few more inches in depth.

You you need to have a converation. Lots of suggestions hereabouts if you contractor can't think 'inside the box..'

If you like Krell sound why not stay with Krell mono?

Will the stereo cabinet allow for adequate ventilation of your Krell?

Bust out the back of your stereo cabinet. Have a carpenter bust it out and expand it into the stud wall, there's atleast 4" hidden back there. I've seen it done for TV's, why not your amp?

You must have forgotten the proper sequence to getting things done - You build your new home to fit your audio system and not the other way around :-).

I would suggest you not sell off your Krell but instead try to work with what you have. Firstly they are good amps and secondly it is not advisable to place your power amp in an enclosure. You'll going to have heating problem, regardless of whatever amps you are going to get. The only amp I know that does not get too hot are the McIntosh because they are class B amps. If you insist on fitting your amps in your cabinet and the McIntosh sound fits your taste, you might want to give it a shot.

How about the new Ayre MX-R monoblocks--only 18 3/4 inches long. From the Ayre website:
Dimensions
11" W x 18.75" D x 3.75" H
(28cm x 48cm x 9.5cm)

But probably too beautiful to hide in a cabinet! There is a new review in Stereophile.

Interesting that you're building a new home, have an amp that you love and couldn't find a way to accommodate it somehow into the new architecture. Is this cabinet custom built or off the shelf and that's the reason it won't fit?
