I spoke with Steve McCormack about this issue recently. In fact, I originally e-mailed Steve, and he called me personally to discuss the topic because he believed it was important.
Steve was adamant about the amplifier (DNA-2 Deluxe Rev. A+) having sufficient room to "breath" and dissipate heat. The DNA-2 gets pretty warm, though not hot. As I recall, 6" minimum all around was the minimum requirement, and he wasn't thrilled with the amp being in a cabinet even with perforated sides and open back, although he said the addition of a small fan to circulate air around the amp would be beneficial and allow placement in a cabinet. He said the amp would operate properly if it got hot, but over time the excess heat would prematurely wear the electronics leading to a shortened life span of the amp.
The requirements for your amp may vary due to the lower power output, and smaller dimensions, but the concept remains the same...room for air to circulate around the amp and dissipate heat.
