Also the EV Q44 isn't "some model of good PRO amps years 78 /85" but rather 2009 or so... So you need to clarify this matter. BTW Bryston 4B Pro, no fan, could be another nice possibility but not sure it would fit the max price target of 500 Euros. You'll see in Europe (if they were distributed there). Regards,

BGW 750 series, at least the "D" has a fan "high or low" switch. I bypassed and mounted a muffin fan with a speed control and run that whisper quiet, doesn't even get warm when pushed.

My little BGW 250D does not have a fan.
