Pass X350.5 Heat Output

I also have the XA30.5, and find it runs quite cool relative to my tube amp.

A couple of moderating factors: 1) It's in my main living area (about 900 sq. feet) so the heat it generates is not a problem. 2) My speakers (the Acoustic Zen Adagio's are an easy load for the amp at 6 ohms and 89 dB efficiency.

I will say that it generates less heat that my Audio Research VT-100 Mk II does. So if you're coming from another solid state amp, particularly a Class D amp, you will notice that it runs warm. However, if you are coming from a tube amp, however, you might find it runs cooler.

I owned the pass labs 350.5 and heat was never an issue, I currently own the pass xa 160.5 monoblocks and they can produce enough heat to be uncomfortable at times. Good luck

Great. Thank you for all the responses. My listening sessions are usually 1-2 hours so the X350.5 might be fine. I have been advised that the X250.5 puts out 40% less heat so that might be just right.

What I said earlier; use a Purist Audio powercable. Wenn you buy a X250.5 it will give you the feeling you bought a X350.5. Goodluck!
