Advice on Integrated Receiver

@carlsbad no power conditioners, etc. in the setup.  P6 --> Schiit Mani phono pream --> CAX81 --> Speakers

Any floor standing you’d recommend? I know that’s a pretty open-ended question, just soliciting some opinions.

The speakers are fine. I still own the MA Silver 8s in a second system. When they were in my main system I drove them with a Krell (150/300 W/ch) and a Vincent (also 150/300 w/ch).

I auditioned these speakers (with PrimaLuna Evo 300) and I was not impressed.  And I think highly of Monitor Audio, I loved my bookshelf speakers. I just found no musicality/soul from the Silver 300s.

But maybe with more raw power? Under 5K you have a lot of choices.  such as 

If you don't like them with 80WPC I don't see how more WPC will make them different enough to change their signature. You will likely be happier spending any $ on new speakers instead of a new amp. Keep the amp, change speakers.

Been awhile, but I remember reading the review in Stereophile of those speakers. I'm inclined to think it may be your amp. And not necessarily the power, but the amp itself.You know anyone else with another integrated you could try?
