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

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!

Paraneer,
You're absolutely right: it is a bit overkill getting an extra pre-amp, which is what I'd be getting with two Marantz PM15S2's. I would prefer a power amp/integrated, but Marantz is not offering that option.

That's what I currently do: I bi-amp my Arcam Alpha 9 integrated with my Alpha 9 power amp.

Yes, I'm a big Arcam fan; I'm waiting to see what comes next: the A38/P38 is now several years old, and Arcam tells me they are coming out with something new soon.

I also own Marantz, and do really like the Marantz sound; the PM15S2 is on sale right now, so it's making me take a serious look at this.

My budget is roughly $4,000, and I keep saving up. I'm open to all suggestions about the best combination I can get to bi-amp with my B&W's.

Thanks again,
Jeff

Nah, that means nothing ...
I dont want to get off track. But this is an irreponsible comment.
Doses are giving by body weight/BMI, which would be higher than other countries in the US.
Just looking at data means nothing ... sorry, a lot of other variable are reponsible for changing dosage amount.
