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 group of us all bought an amplifier of Japanese origin, I was the only one that installed fans, and my unit lasted about 2-3 times longer than the rest of them before the caps failed. So I strongly recommend installing the fans for proper cooling.

Czarivey,
Are you an anesthesiologist? Are you even connected to the medical profession?

Anesthesia is a dangerous drug. FYI Doubling the dose can kill someone.

Paraneer,
The amp would be driving a pair of B&W 805 Nautilus speakers, using Kimber 8TC speaker cable.
I am thinking of getting two PM152SB's, and running them in bi-amp mode.
That's what I do with my current amps, a pair of older Arcams.

I'm biomed tech. I'm between medicine and technology.

The current doses practiced in US for local anasthesia are way more than enough and it takes extremely long time for post-anasthesia recovery. I've compared the dosages given between different countries even vs. Canada as well.

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!
