can the allen heath cq-18 power the sennheiser HD 650 headphones
To compare I can only state that my DT770 PRO at 250 ohm work very well.
I would say that it is OK at 300 ohm also.
Thank you! I am trying to decide which is the best headphone to use. But I do not want to buy just any other headphone as I already have great bluetooth headphones (PX7 S2 and the Apple Max) … so I want to as close to an audiophole “WIRED” headphone, without selling my kidney. LOL!
