Amp ventilation question

Hi group,
I have my eyes on the Marantz Reference PM15S2B Limited integrated; Marantz recommends a minimum of about 8" clearance on top, back and sides for proper ventilation. I have a Timbernation maple rack that's open on the sides and back, so that's not a problem. However, this amp would be going on a shelf with about 7" clearance on top.

Think that would be a problem? We're only talking about an inch, which I don't think would be a big deal, but wanted to run it by you folks.

Thanks in advance for your input,
Jeff

I own the amp you are looking at. I also have 4 1/2" of top clearance for it my open rack. Absolutely no problems whatsoever.

As is the case with just about anyone offering a product or service, they are being overly cautious in this hyper-litigious society of ours. I believe their 8" caveat is right next to the warning not to spill any McDees hot coffee on it either.

BTW, its a great amp and I highly recommend it. I don't know what you intend on driving with it, but I drive a pair of 4 Ohm Vienna Acoustic Bach Grands with mine, and the Marantz has taken these speakers to new heights.

Very nice speakers Jeff. Thanks for sharing.
I am curious though...sounds like your a fan of bi-amping but why consider two integrateds to get the job done? Seems like a waste of a pre-amp section on one of the Marantz's.

Why not consider one integrated and a power amp? Or a pre-amp and two power amps? I have seen and heard B&W 805 Diamonds bi-amped using an Arcam A38 integrated ($2400) and an Arcam P38 power amp ($1600) with very impressive results. It would be cheaper too than two PM15S2's. And your an Arcam guy!
