Pass X350.5 Heat Output

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

The xa160.5 is like listening to tubes, very easy on your ears, with a blacker background and a cleaner sound across the board it also has more density, a richer sound, the 350.5 brings loads of detail from the midrange and higher but lacks the fullness and detail in the midbass perhaps a little thin in that area but it has excellent jump factor, tremendous speed, hope that helps Bmwmcab I'm not real good with words.

Like Bo said the 350.5 has more speed at the bottom end and more jump factor but the XA160.5 has more mid bass detail and purity the advantage the 160.5 has over the 100.5 is more details can be heard. If I needed a sub woofer amp I would choose the 350.5 but for everything else in my system the 160.5 was superior. Good Luck Hasse
