Tube preamp top clearance--McIntosh or in general


Does a tube preamp really need 6-inches of top clearance?
Specifically, the McIntosh C2300, already 7+ inches high,
according to the manual, needs 6 inches clearance. Thats 13+ inches, unusually high for a rack shelf that is not
the topmost one (mine at least). There are 6 12ax7 tubes.
Any thoughts? Thanks.

Keep in mind that the style of rack matters a lot. If you have a rack that's open on all sides, I do, then top clearance isn't as crucial. If the rack is enclosed or partially enclosed then it' very important. As someone said you can use a fan, and as always a little common sense goes a long way. Happy listening!
Go over to Audiokarma and do a search on the McIntosh Discussion Forum. You will find a lot of (mostly) useful information on the C2300 including comparisons with other McIntosh preamps.

Here is one link to a review by TonePub:

I listen to vinyl 90%+ of the time, but the line stage seems good on its own and most of my CD's are very listenable through it. I can't compare to your C46 because I have never heard it.
