HE4THENThanks for the reply. I've done a bit of searching for a suitable amplifier but could not really say what is the proper one for such a scenario (NU Audio Pro -> Amp -> JBL Control 5 + sub.) Does it affect or do I lose any benefits of the card and sound quality going from the card into an amplifier and then going to the speakers (absolute greenhorn when it comes to audio)? Would it be be better to just go directly into some active speakers such as the Presonus Eris E5 for example? Though I'd really prefer to use the Control 5's with a sub to be honest.
HE4THENThanks for your extensive answer. Learned quite a lot.So that would mean I would be able to drive these with, let's say, either one of these for example: the t.amp E-400 (2 x 190 W at 4 ohms) - just about enoughMalone DX800 (2 x 400W at 4 ohms) - more than necessary(?) As for the sub-woofer I would just get a separate (active) one and connect it to the 'C/SUB' port on the second NU Audio Pro card? I've used them (JBL Control 5's) only for a day or so with an old Denon AV Receiver. That thing went ablaze so I had not used them since and was probably not suitable anyway. Is 2x2.5mm² (OFC copper) for a cable sufficient? There are listings for ~19USD at 15m length. To EVGA: For some posts there should be a 'buy me a coffee option'. Vivicector surely would deserve one.
