Hi guys, have a question, I am using PrimaLuna Integrated Tube Amp where it comes with 4Ohm and 8Ohm output. I am paring the Amp with my ProAc Tablette 10 Signature Speakers which published to have 10 ohm nominal impedance. I have tried both output and 4 ohm seems to gives better high end output but lack on bass. and 8ohm is more for overall. My question is which output should I choose 4ohm or 8ohm and is it safe connecting for 4ohm? thanks.

It’s best to connect to the output of the tube amp with the nearest ohm rating to the speaker to get best results.

No, you will not damage anything if you connect to 4ohms, but you will not be getting the best out of the combination.

Why not send an email to manufactures, As there 10omh i would have thought 8 would be the best setting

Definitely 8ohm.
If you connect to 4ohm, the reflected impedance at the valves will be higher, which may or may not be a problem. Better not to risk it.
